How to Create CI-CD Pipeline for ReactJS application

What is the CI/CD pipeline?

Continuous integration/continuous delivery (CI/CD) is a software development practice that involves frequently merging code changes into a central repository and automatically building, testing, and deploying code changes. The goal of CI/CD is to enable organizations to release software updates more frequently, with fewer errors, and with more confidence.

A CI/CD pipeline is a set of automated processes that manage the build, test, and deployment of code changes. The pipeline typically consists of several stages, such as:

  • Build: This stage compiles the code and runs automated tests to ensure that the code is working as expected.
  • Test: This stage runs a variety of tests on the code, including unit tests, integration tests, and automated acceptance tests.
  • Deploy: This stage takes the code that has been built and tested and deploys it to production or staging environments.
  • Monitor: This stage monitors the deployed code for any issues or failures and generates alerts if necessary.

CI/CD pipelines can be implemented using a variety of tools, such as Jenkins, GitLab, or Azure DevOps. These tools provide a way to automate the build, test, and deployment process, as well as track the progress of code changes through the pipeline.

Using a CI/CD pipeline can help organizations release software updates more quickly and with fewer errors, as well as improve collaboration among developers by enabling them to merge code changes more frequently.

A sample CI/CD pipeline for a ReactJS application

Here is an example of a CI/CD pipeline for a React.js application using AWS CodeBuild:

First, you will need to create an AWS CodeBuild project. This can be done through the AWS Management Console or using the AWS CLI.

Next, you will need to set up your source code repository. This could be a Git repository hosted on GitHub, GitLab, or Bitbucket, or it could be an Amazon S3 bucket.

In the CodeBuild project settings, you will need to specify the build environment for your project. This will include the operating system, runtime, and build tools that will be used to build and test your code.

You will also need to specify the build commands that CodeBuild should run. These will typically include commands to install dependencies, build the React.js application, and run tests.

Once the CodeBuild project is set up, you can trigger a build by pushing code changes to the source code repository or by manually starting a build through the CodeBuild console.

As the build runs, CodeBuild will execute the specified build commands and report the build status in real time.

If the build is successful, you can configure the pipeline to automatically deploy the built application to a staging or production environment. This could be done using AWS CodeDeploy or another deployment service.

Finally, you can set up monitoring and alerts to notify you if the deployed application experiences any issues or failures.

This is just one example of a CI/CD pipeline for a React.js application using AWS CodeBuild. There are many other tools and services that can be used to implement a CI/CD pipeline, and the specific steps will vary depending on your specific needs and requirements.

A sample buildspec file given below for the reference

version: 0.1
      - echo Installing source NPM dependencies...
      - npm install
      - cp .env.development .env.production.local
      - echo Build started on `date`      
      - npm run build
    - '**/*'
  base-directory: build
    - './node_modules/**/*'
