Why DevOps is the Perfect Choice for Mobile App Development?

Monday, September 14th, 2020

DevOps for mobile app development is a smart approach to ensure smooth application delivery from initiation to production. It makes the process more efficient, streamlined, and flexible. How? By breaking the development operations barrier. Read this post to know the significance of DevOps in Mobile App Development and how it can benefit your business.

What is DevOps?

DevOps

DevOps isn’t a technique or process, it is a unique approach that ensures effective collaboration between all the stakeholders (developers, managers, and other operations staff) included in creating a reliable digital product. DevOps helps to:

  • Bridge the gap between operations & development so that all can work in a team;
  • Overcome the challenges involved in continuous software delivery;
  • Brings together agile, continuous delivery, and automation.

Moreover, DevOps lowers development costs, accelerates the release cycle, and improves efficiency. According to a study (Source: UpGuard), organizations integrating DevOps showed:

  • 63% improvement in the quality of their software deployments
  • 63% released new software more frequently
  • 55% noticed improved cooperation and collaboration
  • 38% reported a higher quality of code production

Six Essential Elements of the DevOps Approach

DevOps

Continuous Planning

It brings together the complete project team to a single platform to define application scope and determine the possible outcomes & resources.

Continuous Integration

It emphasizes frequent error-free builds and ensures its seamless integration into the last developed code.

Continuous Testing

It helps in the early detection of bugs. It ensures the performance and reliability of the application and the infrastructure as it moves from development to production.

Continuous Monitoring

It helps in issues identification and resolution. It ensures the stability and proper functioning of the app.

Continuous Delivery

It assists in the delivery of software/updates to the production environment in smaller increments and ensures faster release.

Continuous Deployment

It is a strategy where any code that crosses the automated testing phase gets auto release to the production environment.

How to Implement Mobile DevOps?

The three fundamentals to implement mobile DevOps:

DevOps implementation

Continuous Integration and Delivery

The code should be written in such a manner that other teams can easily integrate. All assets—from scripts, text files, configuration, documents, to code should be traceable. Continuous integration comes with continuous delivery. It ensures fast delivery.

Testing and Monitoring

Mobile app testing is quite significant and should be carried out in the real environment in addition to emulators & simulators. An automated tested process has numerous benefits— it is problem-solving, results in early bug detection, & helps in frequent build handling. Continuous performance monitoring can be done by integrating third-party SDKs (like a crash report, log, etc.) to identify the cause of failure.

Quality Control

It is imperative to measure and verify all components of the code from inception to production, including all modifications that took place during the process. The ratings and feedback on the app store need to be monitored constantly to address the issues quickly and determine the scope of improvement.

How Mobile DevOps is going to Benefit Your Business?

Reduced Release Time

Mobile DevOps offer a smart way to fix issues that originated within the product. The continuous integration in DevOps along with the best test setup ensures a faster solution to problems and compresses applications time to release.

Better Customer Experience

The prime goal of a company is to deliver better services and products. DevOps help to create a quality app using continuous automated testing. This results in better customer experience and satisfaction.

Better Software Quality

DevOps ensures fast development, high quality, stable software, and more frequent releases. When coupled with Agile, it results in better collaboration and helps in solving a problem quickly. DevOps ensures close monitoring of everything from user experience, performance, to security. Thus results in stable and robust software delivery.

Reduced Risks

Mobile DevOps significantly reduces risks. Automated Testing in the development lifecycle ensures that every bug is detected and resolved before the release of the product.

Innovative Toolkits

DevOps offers creative & feature-rich tools to enhance mobile application quality and scalability. These tools foster capabilities for implementing continuous delivery for a large number of releases. Also, the release management tool offers a single collaboration platform for all the teams and provide traceability of every product release.

Microservices

Monday, July 13th, 2020

The world we live in is dynamic, in fact, the only sure-fire constant that you may find in it is the fact that change here, is a rather constant set of affairs. When we narrow down our view of the world to software and technology this seems to take a whole other meaning, not only is change constantly occurring, it is occurring so rapidly that even the best of our brains have difficulty keeping up with it.

This brings us to a very interesting question- how can the various applications and other software on your electronic devices accommodate such a variety of change and that too this fast? This question lies in the mind of all developers, before they even launch a new application, for example, they build it already capable of inculcating new updates, etc. Now comes the question of rapidity. Earlier the applications used to have monolithic architecture. Under this, the entire application was built as one independent unit. This resulted in any induction of change to be an extremely time-taking and tedious process as any change affected the entire system- even the most minuscule modification to even a tiny segment of the code could require the building or deployment new version of the software.

But the world as we know it needed to be much faster than that, this where Microservices came and replaced Monolith applications. Microservice Architecture or as it is popularly known- Microservices is today one of the foundation components of creating a good application aimed and precise and immersive delivery of service. It is a style of Architecture that designs the application as an amalgamation of services that can easily be maintained over a long period of time and deployed if need be both with one another or independently. It tackles the problems posed by earlier models by being modular in every single aspect. It is a rather distinctive method of creating systems of software that emphasizes the creation of single-function modules with strictly defined operations and interfaces.

Since there are no official templates available to either design or develop or even base microservice architecture upon, providers of these services often find themselves in a more creative space than usual, however over time there has come some uniformity in types and characteristics of services offered or how this architecture is developed. Topping the charts, of course, is its uncanny ability to be divided into numerous components with each being able to be tweaked and redeployed independently so if one or more service is to be changed, the developers do not have to undertake the gargantuan task of changing the entire application.

Another defining characteristic carried by it is the simple fact that this is built for business. In previous architectures the traditional approach with separate teams for User Interface, Technology layers, Databases, and other services and components was present. Microservice comes with the revolutionary idea of cross-platform teams, with each team being given the task of developing one or more very specific products based on any number of services (as available within the architecture) with the help of a message bus for the purpose of communication. It functions on the motto- “You build it, you run it.” Hence these teams are allowed to assume ownership of their developed product for its lifetime.

Another well-founded achievement of Microservices is its quality of resistance to failure. The probability of failure is extremely plausible since a number of services which on their own are quite diverse as well are continuously communicating and working together. The chance of a service failing is rather high. In such cases, the client should withdraw peacefully allowing other services around its function. Moreover, Microservices come with the ability to monitor over these services which exponentially reduces these chances of failure, and if and when one service or the other does fail it is thus well equipped to cope up with it.

As you may realize reading thus far, that Microservice architecture in all its application and potential seems to be a design capable of bringing a revolution in the industry, hints of which have already been seen as it has efficiently and rather completely replaced the traditional monolith models. It is an evolutionary design and it is an ideal choice for a designer who is unable to anticipate the types of changes that product may have to undergo in the future. In fact, it is built to accommodate unforeseen changes and that is why as development becomes more and more rapid a larger share of industry is switching from Monolithic to Microservices.

Some of the big players adding to its prestige are Netflix and Amazon. Both requiring one of the most widespread architectures possible in the industry. They get a number of calls from a variety of devices which would simply have been impossible to be handled by the traditional models they used before that.

One major drawback faced globally among Microservices enthusiasts is the fact that the logic, schema and other information that would otherwise have been the company’s intellectual property implicit their own minds now have to be shared across the various cross-platform services. But there is no way around it, in the world around us where most software is being developed over cloud environments this is more or less a philosophical question that whether we should even keep a secret. But along with this aby accepting regression tests and planning around backward compatibility a lot of such tricky scenarios could easily be avoided. Anyway, compared to the ocean of benefits that one receives from Microservice architecture it can remain a rhetorical question whether companies have any other options available. The pros outweigh the cons by far and in the coming times, this is going to be even more sought after model than it is now.

7 Hybrid Cloud Essential Security Elements

Tuesday, June 16th, 2020

Globally, the emergence of cloud computing and cloud storage has changed the dynamics of how the organizations create, store, execute, and operate the data. It is well known that public cloud platforms allow organizations with little or no cloud structure to migrate to the cloud. But several organizations set up their private cloud networks as it allows them to protect their intellectual property more securely. 

Hybrid Cloud: An Intro

No doubt, security is a big concern for every organization. As IT applications and infrastructure move to the public cloud, the chances of a security breach can increase exponentially. But the problem isn’t the cloud service!

According to Gartner, public cloud services offered by leading providers are secure and identified the real problem as the way in which those services are used. The challenge, then, is figuring out how to deploy and use public cloud services in a secure manner. And hence the emergence of hybrid cloud is considered as the game-changing scenario as it offers the best of both the cloud platforms. 

Security Threats in Hybrid Cloud Platform

There are few security challenges which you need to address while working on the hybrid cloud platform. Check out these 7 most crucial hybrid cloud challenges here-

Adherence to Compliance-Regulation

With the rigorous data security norms such as GDPR coming into effect, the regulatory requirements for staying compliant have become even stricter. As the data moves from your private cloud network to the public cloud network in the hybrid cloud computing model, you need to take extra preventive measures to stay compliant.

Maintaining Data Protection and Encryption

Every database, workloads, and content in cloud must be protected from internal and external threats aimed at stealing critical data. In such a case, Encryption helps offset concerns associated with relinquishing data control in the cloud because it limits the chance of a breach and hackers won’t be able to decrypt the data. 

Ambiguity in Service Level Agreements (SLAs)

When you are opting for a hybrid cloud platform, you are also allowing the administration of the data to your public cloud service provider. There are also challenges that companies face with regard to the accountability of the data loss. It is important to make sure that the service providers have ensured the confidentiality of the data. 

Network Security

Managed network security services help simplify network security by reducing the complexity that evolves from managing different operating systems, network asset failures, and remote access queries. Software-defined network technologies and automation are increasingly being used with the hybrid cloud to centralize security monitoring, management, and inter-workload protection. 

Data Redundancy Policy and MFA

It is recommended that organizations must have a data redundancy policy in place to ensure the back-up in case there is only one data center. Moreover, organizations need to set up the multi-factor authentications methods to prevent any unauthorized access.

Workload-centric Capabilities

Since workloads can move between clouds, they need to carry their security methods with them. With workload-centric security, controls are built-in and stay with each workload wherever it runs. The plus point is that it can benefit DevOps as well, enabling security controls to be more easily integrated into new applications. Every time a new workload is provisioned, security controls are already there. 

Strict Monitoring of Regulatory Changes

With new mandates continuously in the action for cybersecurity and data protection, financial firms need a mechanism for proactively tracking these changes for betterment. Robust predictive analytics, such as those used by a controls database, is designed to simplify and accelerate the discovery of regulatory changes and can deliver actionable insights for rectification.

Conclusion

Before starting your organization’s hybrid cloud journey, think carefully about your long-term approach and what you will expect from your hybrid cloud environment in the years to come. No solution is perfect, though, so they need to keep the challenges associated with hybrid clouds in mind as they roll out their network deployments. By considering these seven elements of hybrid cloud security, you can help your organization transition smoothly between on-premises and cloud environments.

Device Shadow

You can create a determined, virtual version or Device Shadow of every device connected to an AWS IoT core. It is a virtual representation of every device by which you can virtually analyze a device’s real-time state w.r.t applications and other devices interacting with it. It also lets you recover the last reported state of each device connected to the AWS cloud. Besides, the Device Shadow provides REST APIs that make it more convenient to create interactive applications.

Rules Engine

The Rules Engine empowers you to create a scalable and robust application that exchanges, processes the data generated by the connected devices. It prevents you from managing the complex and daunting software infrastructures. Moreover, it evaluates and modifies the messages published under the AWS IoT Core and delivers them to another device or cloud service.

Authentication and Authorization

AWS IoT Core provides industry level security for the connected devices as it allows mutual authentication and peer-to-peer encryption at every connection point. This means that the data is only transferred between the devices that have a valid and proven identity on AWS IoT Core. There are majorly three types of authentication mechanism:

  • X.509 Certificate-Based Authentication
  • Token-Based Authentication
  • SigV4

Devices connected using HTTP can use either of the above-mentioned authentication mechanisms whereas devices connected through MQTT can use certificate-based authentication.

AWS IoT and Mobile SDKs

The AWS IoT Device SDK allows you to connect your hardware device or your application to AWS IoT Core instantly and efficiently. It enables your devices to connect, validate, and exchange messages with AWS IoT Core incorporating the web protocols like MQTT, HTTP, or WebSockets. Moreover, developers can either use an open-source AWS SDK or can create their SDK to support their IoT devices.

Collaborative Development: This part involves drafting a development plan, programming required, and focusing on the architectural infrastructure as it the building block for an enterprise. It is considered as a business strategy, working process, and an assemblage of software applications that promotes several enterprises to work together on the development of a product. Whereas, the infrastructure management incorporates systems management, network management, and storage management which are handled on the cloud.

Continuous Testing: This stage increases the efficiency and speed of the development by leveraging the unit and integration testing. The payoff from continuous testing is well worth the effort. The test function in a DevOps environment supports the developers in effectively balancing speed and quality. Leveraging automated tools can decrease the cost of testing and enable QA experts to invest their time more productively. Besides, CT compresses the test cycles by allowing integration testing earlier in the process.

Continuous Monitoring: Consistent monitoring maintains the quality of the process. Hence, this stage monitor changes and address the flaws & mistakes immediately, the moment they occur. Besides, it enables enterprises to effectively monitor the user experience and improve the stability of their application infrastructure.

Continuous Release & Deployment: This step incorporates monitoring release and deployment procedures. Here, a constant CD pipeline will help in implementing code reviews and developer check-ins seamlessly. This step incorporates monitoring release and deployment procedures. Here, a constant CD pipeline will help in implementing code reviews and developer check-ins seamlessly. The main focus is to depreciate the manual tasks, scale the application to an Enterprise IT portfolio, provide a single view across all the applications and adopt a unified pipeline that will integrate and deploy tasks as and when they occur.

Collaborative Customer Feedback & Optimization: Customer feedbacks are always important as it helps organizations to make adjustment decisions and actions that can enhance the user experience. This stage enables an instant acknowledgment from the customers for your product and helps you implement the corrections accordingly. Besides, customer feedbacks enhance the quality, decreases risks & costs, and unifies the process across the end to end the lifecycle.

Now let us move on to the how DevOps helps driving business growth but before that:

Azure Bastion: Secure way to RDP/SSH Azure Virtual Machines

Monday, March 2nd, 2020

Microsoft Azure has recently launched Azure Bastion; a managed PaaS service to securely connect to Azure Virtual Machines (VMs) directly through the Azure Portal without any client needed.

Generally, we connect to the remote machines by either RDP or SSH. Before Bastion, if we need to connect to a VM in Azure we either need to expose a public RDP/SSH port of the server(s) or we need to provision a separate jump box server with said ports exposed and then connect to the private machines via the jump box server.

Exposing RDP/SSH ports over the Internet is not desirable and considered as a security threat, and with Azure Bastion, we can connect to Azure VM(s) securely over SSL, directly in Azure Portal and without exposing any ports. This also enables clientless connectivity meaning no client tool like mstsc is needed. It just requires a supported browser to access the VM.

Key points

  • Azure Bastion is a fully managed PaaS service that provides secure and seamless RDP/SSH access to Azure VM(s)
  • No RDP/SSH ports need to be exposed publicly
  • No public IP is required for VM(s)
  • Access VM(s) directly from the Azure portal over SSL
  • Help to limit threats like port scanning and other malware
  • Makes it easy to manage Network Security Groups (NSGs)
  • It is basically a scale set under the hood, which can resize itself based on the number of connections to your network
  • Azure Bastion is provisioned within a Virtual Network (VNet) within a separate subnet. The name of the subnet must be AzureBastionSubnet
  • Once provisioned, access is there for all VMs in the VNet, across subnets
  • Get started within minutes

Getting Started

  • Select the VNet, in which you have the VM(s), which you want to connect. Create a subnet on which the bastion host will be deployed. Make sure that the range of networks is at least /27 or larger and the name of the subnet is AzureBastionSubnet.
  • Now go to the Azure portal and create a Bastion service and fill in the required details.
  • Once the Bastion is provisioned, just navigate to the VM, you want to RDP/SSH and click Connect. There you will see an option to connect using Bastion.
  • Just enter the username and password and Connect. You can also login using a username and SSH private key for Linux if it is configured.
  • This is it. When connected, the remote session will start in the browser window.

Limitations

The service is not available in all regions, and the Azure folks are working on adding it to all regions eventually. As of now, the file transfer service is not available but we hope this feature will get added in the future, however, text copy-paste is supported. Keep visiting the service documentation for more details and feature updates.

Microservices

Friday, January 24th, 2020

The world we live in is dynamic, in fact, the only sure-fire constant that you may find in it is the fact that change here, is a rather constant set of affairs. When we narrow down our view of the world to software and technology this seems to take a whole other meaning, not only is change constantly occurring, it is occurring so rapidly that even the best of our brains have difficulty keeping up with it.

This brings us to a very interesting question- how can the various applications and other software on your electronic devices accommodate such a variety of change and that too this fast? This question lies in the mind of all developers, before they even launch a new application, for example, they build it already capable of inculcating new updates, etc. Now comes the question of rapidity. Earlier the applications used to have monolithic architecture. Under this, the entire application was built as one independent unit. This resulted in any induction of change to be an extremely time-taking and tedious process as any change affected the entire system- even the most minuscule modification to even a tiny segment of the code could require the building or deployment new version of the software.

But the world as we know it needed to be much faster than that, this where Microservices came and replaced Monolith applications. Microservice architecture or as it is popularly known- Microservices is today one of the foundation components of creating a good application aimed and precise and immersive delivery of service. It is a style of Architecture that designs the application as an amalgamation of services that can easily be maintained over a long period of time and deployed if need be both with one another or independently. It tackles the problems posed by earlier models by being modular in every single aspect. It is a rather distinctive method of creating systems of software that emphasizes the creation of single-function modules with strictly defined operations and interfaces.

Since there are no official templates available to either design or develop or even base microservice architecture upon, providers of these services often find themselves in a more creative space than usual, however over time there has come some uniformity in types and characteristics of services offered or how this architecture is developed. Topping the charts, of course, is its uncanny ability to be divided into numerous components with each being able to be tweaked and redeployed independently so if one or more service is to be changed, the developers do not have to undertake the gargantuan task of changing the entire application.

Another defining characteristic carried by it is the simple fact that this is built for business. In previous architectures the traditional approach with separate teams for User Interface, Technology layers, Databases, and other services and components was present. Microservice comes with the revolutionary idea of cross-platform teams, with each team being given the task of developing one or more very specific products based on any number of services (as available within the architecture) with the help of a message bus for the purpose of communication. It functions on the motto- “You build it, you run it.” Hence these teams are allowed to assume ownership of their developed product for its lifetime.

Another well-founded achievement of Microservices is its quality of resistance to failure. The probability of failure is extremely plausible since a number of services which on their own are quite diverse as well are continuously communicating and working together. The chance of a service failing is rather high. In such cases, the client should withdraw peacefully allowing other services around its function. Moreover, Microservices come with the ability to monitor over these services which exponentially reduces these chances of failure, and if and when one service or the other does fail it is thus well equipped to cope up with it.

As you may realize reading thus far, that Microservice architecture in all its application and potential seems to be a design capable of bringing a revolution in the industry, hints of which have already been seen as it has efficiently and rather completely replaced the traditional monolith models. It is an evolutionary design and it is an ideal choice for a designer who is unable to anticipate the types of changes that product may have to undergo in the future. In fact, it is built to accommodate unforeseen changes and that is why as development becomes more and more rapid a larger share of industry is switching from Monolithic to Microservices.

Some of the big players adding to its prestige are Netflix and Amazon. Both requiring one of the most widespread architectures possible in the industry. They get a number of calls from a variety of devices which would simply have been impossible to be handled by the traditional models they used before that.

One major drawback faced globally among Microservices enthusiasts is the fact that the logic, schema and other information that would otherwise have been the company’s intellectual property implicit their own minds now have to be shared across the various cross-platform services. But there is no way around it, in the world around us where most software is being developed over cloud environments this is more or less a philosophical question that whether we should even keep a secret. But along with this aby accepting regression tests and planning around backward compatibility a lot of such tricky scenarios could easily be avoided. Anyway, compared to the ocean of benefits that one receives from Microservice architecture it can remain a rhetorical question whether companies have any other options available. The pros outweigh the cons by far and in the coming times, this is going to be even more sought after model than it is now.

Queuing Tasks with Redis

Thursday, January 23rd, 2020

Introduction and background

Redis is an open-source data structure that is used for in-memory storage and helps developers across the globe with the quick and efficient organization and utilization of data. Even though many developers worldwide are still struggling to decide which open-source software application to use, Redis is quickly growing to be a widely popular choice. Currently, more than 3000 tech joints, including our team, are using Redis.

Redis supports several data structures, including lists, sets, sorted sets, hashes, binary-safe strings, and HyperLogLogs. Our team uses Redis to support queuing in this project.

Queuing is the storing or deferring of tasks of operation inside a queue so that they can be used later. It comes into use for operations which are large in number and/or takes up a lot of time. Tasks can be executed in two different methods –

  • Tasks can be executed in the same order they were inserted, or
  • Tasks can be executed at a specific time.

Challenges

For this project, we needed to download large files, which is extremely time-consuming. To make the process more time-efficient, we decided to use queuing to effectively manage the download request. These download requests were added and served in the FIFO order.

Moreover, we wanted to retry the request in the time interval of one hour if it fails, until it fails three times. After this, the request is marked as failed and then removed from the queue. Our team soon found that manually creating and managing separate queues was rather inefficient, time-consuming, and troublesome, which hinted that we needed a new solution. This is where Redis comes in.

Solution

To create and manage separate queues more effectively, we put Kue npm package to the test. We hoped that it would make our task less time-consuming and more efficient.

And what exactly is Kue? Kue is a priority job queue package that is built for node.js and backed by Redis. What makes Kue so appealing for developers is that it provides us with a UI where the status of queues is displayed. This means that we can see the current status of the queues in real-time, thus helping us work better and smarter.

To use Kue, you have to first install it, then create a job Queue with Kue.createQueue(). The next step is to create a job of type email with arbitrary job data using create() method. This enables the return of a job, which will be saved in Redis using save() method.

Then, after the jobs are created, the next step is to process them using process() method, after which failed jobs should be removed. You can then add Kue UI if you choose and install kue-UI package.

With this, you will be able to store your request in the Redis queue and then process them in FIFO order.

Connecting GraphQL using Apollo Server

Thursday, January 23rd, 2020

Introduction

Apollo Server is a library that helps you connect a GraphQL schema to an HTTP server in Node.js. We will try to explain this through an example, the link used to clone this project is mentioned below:-

git clone https://[email protected]/prwl/apollo-tutorial.git

This technology and its concepts can be best explained as below.

Challenge

Here, one of the main goals is to create a directory and install packages. This will eventually lead us to implement our first subscription in GraphQL with Apollo Server and PubSub.

Solution

For this, the first step includes building a new folder in your working directory. The current directory is changed to that new folder, and a new folder is created to hold your server code in and run. This will create the package.json file for us. After this, we install a few libraries. After the installment of these packages, the next step is to create an index.js file in the root of the server.

Create Directory

npm init -y

Install Packages

npm install apollo-server-express express graphql nodemon apollo-server

Connecting Apollo Server

Index.js first connects to the Apollo server. Every library is set to get started with the source code in the index.js file. To achieve this, you have first to import the necessary parts for getting started with Apollo Server in Express. Using Apollo Server’s applyMiddleware() method, you can opt-in any middleware, which in this case is Express.

import express from 'express';
import { ApolloServer, gql } from 'apollo-server-express';

const typeDefs = gql`
type Query {
hello: String
};
const resolvers = {
Query: {
hello: () => 'Hello World!'
}
}
`;
const server = new ApolloServer({ typeDefs, resolvers });
const app = express();
server.applyMiddleware({ app });

app.listen({ port: 4000 }, () =>
console.log(`? Server ready at http://localhost:4000${server.graphqlPath}`)
);

The GraphQL schema provided to the Apollo Server is the only available data for reading and writing data via GraphQL. It can happen from any client who consumes the GraphQL API. The schema consists of type definitions, which starts with a mandatory top-level Query type for reading data, followed by fields and nested fields. Apollo Server has various scalar types in the GraphQL specification for defining strings (String), booleans (Boolean), integers (Int), and more.

const typeDefs = gql`
type Query {
hello: Message
}Type Message {salutation: String}
`;
const resolvers = {
Query: {
hello: () => 'Hello World!'
}
};

In the GraphQL schema for setting up an Apollo Server, resolvers are used to return data for fields from the schema. The data source doesn’t matter, because the data can be hardcoded, can come from a database, or from another (RESTful) API endpoint.

Mutations

So far, we have only defined queries in our GraphQL schema. Apart from the Query type, there are also Mutation and Subscription types. There, you can group all your GraphQL operations for writing data instead of reading it.

const typeDefs = gql`
type Query {

}type Mutation {createMessage(text: String!): String!}
`;

As visible from the above code snippet. In this case, the create message mutation accepts a non-nullable text input as an argument and returns the created message as a string.

Again, you have to implement the resolver as counterpart for the mutation the same as with the previous queries, which happens in the mutation part of the resolver map:

const resolvers = {
Query: {
hello: () => ‘Hello World!’
},
Mutation: {
createMessage: (parent, args) => {
const message = args.text;
return message;
},
},
};

The mutation’s resolver has access to the text in its second argument. The parent argument isn’t used.

So far, the mutation creates a message string and returns it to the API. However, most mutations have side-effects, because they are writing data to your data source or performing another action. Most often, it will be a write operation to your database, but in this case, we are just returning the text passed to us as an argument.

That’s it for the first mutation. You can try it right now in GraphQL Playground:

mutation {
createMessage (text: “Hello GraphQL!”)
}

The result for the query should look like this as per your defined sample data:

{
“data”: {
“createMessage”: “Hello GraphQL!”
}
}

Subscriptions

So far, you used GraphQL to read and write data with queries and mutations. These are the two essential GraphQL operations to get a GraphQL server ready for CRUD operations. Next, you will learn about GraphQL Subscriptions for real-time communication between GraphQL client and server.

Apollo Server Subscription Setup

Because we are using Express as middleware, expose the subscriptions with an advanced HTTP server setup in the index.js file:

import http from ‘http’;…server.applyMiddleware({ app, path: ‘/graphql’ });const httpServer = http.createServer(app);
server.installSubscriptionHandlers(httpServer);httpServer.listen({ port: 8000 }, () => {
 console.lo;
});…

To complete the subscription setup, you’ll need to use one of the available PubSub engines for publishing and subscribing to events. Apollo Server comes with its own by default.

Let’s implement the specific subscription for the message creation. It should be possible for another GraphQL client to listen to message creations.

Create a file named subscription.js in the root directory of your project and paste the following line in that file:

import { PubSub } from ‘apollo-server’;export const CREATED = ‘CREATED’;export const EVENTS = {
MESSAGE: CREATED,
};export default new PubSub();

The only piece missing is using the event and the PubSub instance in your resolver.

…import pubsub, { EVENTS } from ‘./subscription’;…const resolvers = {
Query: {

},
Mutation: {…
},Subscription: {messageCreated: {subscribe: () => pubsub.asyncIterator(EVENTS.MESSAGE),},},};…

Also, update your schema for the newly created Subscription:

const typeDefs = gql`
type Query {

}
type Mutation {

}type Subscription {messageCreated: String!}
`;

The subscription as a resolver provides a counterpart for the subscription in the message schema. However, since it uses a publisher-subscriber mechanism (PubSub) for events, you have only implemented the subscribing, not the publishing. It is possible for a GraphQL client to listen for changes, but there are no changes published yet. The best place for publishing a newly created message is in the same file as the created message:

…import pubsub, { EVENTS } from ‘./subscription’;…const resolvers = {
Query: {

},
Mutation: {
createMessage: (parent, args) => {
const message = args.text;pubsub.publish(EVENTS.MESSAGE, {messageCreated: message,});
return message;
},
},
Subscription: {

},
};…

We have implemented your first subscription in GraphQL with Apollo Server and PubSub. To test it, create a new message on a tab in the apollo playground. On the other tab, we can listen to our subscription.

In the first tab, execute the subscription:

subscription {
messageCreated
}

In the second tab execute the createMessage mutation:

mutation {
createMessage(text: “My name is John.”)
}

Now, check the first tab(subscription) for the response like this:

{
“data”: {
“messageCreated”: “My name is John.”
}
}

We have implemented GraphQL subscriptions.
