Building a React application is only one part of modern web development. Once a project grows, developers also need to check code quality, run automated tests, create production builds, manage environment variables, deploy applications, and make sure every release works correctly.
Performing all these steps manually can become slow and repetitive. Moreover, manual deployment increases the chance of mistakes, especially when several developers work on the same application.
This is where CI/CD for React applications becomes useful.
CI/CD allows developers to automate important development and deployment tasks. For example, a CI/CD pipeline can install Node.js dependencies, run lint checks, execute automated tests, create optimized production builds, store build artifacts, and automatically deploy React applications.
In this complete guide, you will learn what CI/CD means for React, how a React CI/CD pipeline works, which tools you can use, how to create a GitHub Actions workflow, how to manage environment variables, and how to deploy React applications automatically.
What Is CI/CD for React Applications?
CI/CD stands for:
- CI – Continuous Integration
- CD – Continuous Delivery
- CD – Continuous Deployment
In React development, CI/CD is an automated workflow that checks, tests, builds, and optionally deploys your application whenever developers make changes to the source code.
A typical React CI/CD pipeline may look like this:
Developer Writes Code
↓
Push Code to Git Repository
↓
CI/CD Pipeline Starts
↓
Install Node.js
↓
Install Dependencies
↓
Run Lint
↓
Run Tests
↓
Create Production Build
↓
Store Build Artifact
↓
Deploy Application
As a result, developers do not need to repeat the same commands manually for every release.
What Is Continuous Integration in React?
Continuous Integration, or CI, focuses on validating new code changes.
Suppose multiple developers are working on the same React application.
One developer adds authentication.
Another developer updates the dashboard.
Meanwhile, another developer modifies API integration.
If these changes are merged without automated validation, one update may accidentally break another part of the application.
Continuous Integration helps prevent this problem.
Whenever developers push code or open a pull request, the CI pipeline can automatically run commands such as:
npm install
npm run lint
npm test
npm run build
If one of these steps fails, the pipeline reports the problem.
Therefore, developers can fix issues before merging the code into the main branch.
What Is Continuous Delivery for React?
Continuous Delivery extends the CI process.
Once the application passes lint checks, tests, and build verification, the pipeline prepares a production-ready version of the application.
For example:
npm run build
Depending on the React project setup, this command creates an optimized production build.
The generated application can then be stored as an artifact or sent to a staging environment.
However, a team may still require manual approval before publishing the application to production.
This workflow is known as Continuous Delivery.
What Is Continuous Deployment?
Continuous Deployment takes automation one step further.
After all validation stages succeed, the pipeline automatically deploys the application.
For example:
Developer Push
↓
Run Lint
↓
Run Tests
↓
Create Production Build
↓
Deploy Automatically
This approach can make releases extremely fast.
However, larger teams may still prefer approval before production deployment.
Why Use CI/CD for React Applications?
React applications can become large and complex. As features increase, manual testing and deployment become difficult to manage.
CI/CD helps automate many repetitive tasks.
For example, developers may normally run:
npm install
npm run lint
npm test
npm run build
Instead of running these commands manually before every release, the CI/CD system can execute them automatically.
This provides several advantages.
Automatic Code Quality Checks
React projects often use tools such as ESLint to identify potential code problems.
A pipeline can automatically run:
npm run lint
This can help detect problems such as unused variables, incorrect syntax, inconsistent coding patterns, and other issues defined by your lint configuration.
As a result, code quality problems can be detected before deployment.
Automated Testing
A CI pipeline can automatically run React tests.
For example:
npm test
Depending on the project, tests may check components, functions, hooks, API-related logic, or complete application flows.
If an important test fails, the pipeline can stop immediately.
Consequently, broken code does not move to the deployment stage.
Automatic Production Builds
A CI/CD pipeline can also create optimized production builds.
For example:
npm run build
The exact output directory depends on the React build tool being used.
For example, some projects generate:
build/
while others may generate:
dist/
Once the build finishes, the pipeline can store or deploy those files automatically.
Faster Deployment
Without automation, developers may need to build the application locally, manually upload files, configure hosting, and verify the deployment.
With CI/CD, the process becomes much simpler.
Merge Code
↓
Run Tests
↓
Build React App
↓
Deploy Automatically
Therefore, development teams can release updates faster.
Consistent Builds
Different developers may have different versions of Node.js, npm, or other development tools.
These differences sometimes cause applications to behave differently across machines.
CI/CD creates builds inside a controlled environment.
As a result, every release follows the same process.
Fewer Human Errors
Manual deployment creates opportunities for mistakes.
For example, a developer may forget to run tests, use the wrong environment configuration, deploy an outdated build, or publish code from the wrong branch.
Automation reduces these risks because the pipeline follows the same predefined steps every time.
How Does a React CI/CD Pipeline Work?
A practical React CI/CD pipeline usually contains several stages.
Source Code
↓
Checkout Repository
↓
Setup Node.js
↓
Install Dependencies
↓
Lint Code
↓
Run Tests
↓
Build Application
↓
Store Artifact
↓
Deploy
Now, let’s understand each stage.
Stage 1: Source Code
The pipeline normally starts from a Git repository.
React projects are commonly hosted on platforms such as GitHub, GitLab, or Bitbucket.
A React project may look like:
react-app/
│
├── public/
├── src/
├── package.json
├── package-lock.json
├── vite.config.js
└── README.md
Different Git events can start different CI/CD workflows.
For example:
Pull Request
↓
Lint + Tests
Push to Develop
↓
Lint + Tests + Build
Push to Main
↓
Production Build
Version Tag
↓
Production Deployment
This approach gives teams better control over releases.
Stage 2: Checkout the Repository
The CI server first needs access to your application source code.
In GitHub Actions, this is commonly done with:
- name: Checkout repository
uses: actions/checkout@v4
After checkout, the CI runner can access files such as:
src/
package.json
package-lock.json
The next stage prepares the Node.js environment.
Stage 3: Setup Node.js
React applications depend on Node.js for package installation, testing, and build tooling.
The CI environment must therefore use a compatible Node.js version.
In GitHub Actions:
- name: Setup Node.js
uses: actions/setup-node@v4
with:
node-version: '20'
The exact Node.js version should match your project requirements.
You can check your local version with:
node --version
You can also check npm with:
npm --version
Keeping Node.js versions consistent helps prevent unexpected differences between development and CI environments.
Stage 4: Install React Dependencies
After setting up Node.js, the pipeline installs project dependencies.
A common command is:
npm install
However, CI environments often use:
npm ci
npm ci installs dependencies based on the lock file and is designed for clean, repeatable installations.
A typical pipeline stage looks like:
- name: Install dependencies
run: npm ci
If dependency installation fails, the pipeline should stop because the application cannot be tested or built correctly.
npm install vs npm ci in CI/CD
Both commands install Node.js dependencies, but they serve slightly different purposes.
npm install is commonly used during normal development.
Meanwhile:
npm ci
is especially useful for CI environments because it installs dependencies according to package-lock.json.
This helps make builds more predictable.
For many CI/CD pipelines, npm ci is therefore a better choice.
Stage 5: Run React Lint Checks
After installing dependencies, the pipeline can analyze the code.
Many React projects use ESLint.
Run:
npm run lint
Your package.json may contain:
{
"scripts": {
"lint": "eslint ."
}
}
If ESLint finds errors that violate your configured rules, the pipeline can fail.
This prevents problematic code from moving to later stages.
Stage 6: Run Automated Tests
Next, execute automated tests.
Depending on your React setup, the command may be:
npm test
or another custom test command.
React applications commonly include several types of tests.
Unit tests can verify small functions or utilities.
Component tests can verify React components.
Integration tests can check interactions between multiple components.
End-to-end tests can verify complete application workflows.
A CI pipeline may therefore look like:
Install Dependencies
↓
Lint
↓
Unit Tests
↓
Component Tests
↓
Build
Fast tests should usually run before expensive build stages.
Example React Component Test
A simple React component might look like:
function Welcome() {
return <h1>Welcome</h1>;
}
export default Welcome;
A testing library can verify that the expected content appears.
For example:
test('shows welcome message', () => {
render(<Welcome />);
expect(
screen.getByText('Welcome')
).toBeInTheDocument();
});
CI automatically runs these tests after developers push code.
Stage 7: Create the Production Build
Once lint and tests succeed, the pipeline can create a production build.
Run:
npm run build
The exact build process depends on your React setup.
For example, a Vite-based project may generate:
dist/
Other build systems may use another output directory.
The production build contains optimized assets prepared for deployment.
Why Production Builds Matter
Development environments contain tools that help developers work efficiently.
Production builds focus instead on delivering optimized files to users.
The build process may optimize JavaScript, CSS, and static assets.
Therefore, production deployments should normally use the generated production build rather than development files.
Stage 8: Store Build Artifacts
Once the build completes, the CI platform can save the output as an artifact.
For example:
CI Pipeline
↓
npm run build
↓
dist/
↓
Upload Artifact
Artifacts can be useful for QA testing, release tracking, debugging, and deployment.
Moreover, the same tested build can move from one environment to another instead of being rebuilt repeatedly.
Stage 9: Deploy the React Application
After creating the production build, the pipeline can deploy it.
React applications can be deployed to many types of hosting platforms.
Depending on your infrastructure, the deployment stage may upload files to a static hosting service, cloud server, container platform, CDN-backed hosting solution, or another web environment.
The general workflow remains similar:
Build React App
↓
Generate Production Files
↓
Authenticate with Hosting Provider
↓
Upload Files
↓
Production Website Updated
Popular CI/CD Tools for React Applications
Several platforms can run React CI/CD workflows.
Common choices include GitHub Actions, GitLab CI/CD, Jenkins, CircleCI, Bitbucket Pipelines, Azure DevOps, and other cloud-based CI platforms.
The best platform depends on where your code is hosted, your deployment infrastructure, and your team’s requirements.
GitHub Actions for React CI/CD
GitHub Actions is a convenient option for React projects hosted on GitHub.
Workflow files live inside:
.github/workflows/
For example:
.github/
└── workflows/
└── react-ci.yml
The workflow can automatically run whenever developers push code or create pull requests.
Create a React CI Pipeline with GitHub Actions
Create:
.github/workflows/react-ci.yml
Then add:
name: React CI
on:
push:
branches:
- main
- develop
pull_request:
branches:
- main
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Checkout repository
uses: actions/checkout@v4
- name: Setup Node.js
uses: actions/setup-node@v4
with:
node-version: '20'
cache: 'npm'
- name: Install dependencies
run: npm ci
- name: Run lint
run: npm run lint
- name: Run tests
run: npm test -- --runInBand
- name: Build application
run: npm run build
This workflow creates a basic React Continuous Integration pipeline.
Understanding the React GitHub Actions Workflow
The workflow begins with:
name: React CI
This gives the workflow a readable name.
Next, the trigger configuration decides when the pipeline runs.
on:
push:
branches:
- main
- develop
The pipeline starts when developers push code to either branch.
Pull request validation is configured with:
pull_request:
branches:
- main
Therefore, developers can detect problems before merging changes into production code.
Setup Node.js in GitHub Actions
The following step installs Node.js:
- name: Setup Node.js
uses: actions/setup-node@v4
with:
node-version: '20'
cache: 'npm'
The cache option can speed up dependency-related operations in future workflow runs.
However, always choose a Node.js version compatible with your project.
Install Dependencies
The workflow then runs:
- name: Install dependencies
run: npm ci
This installs dependencies from your lock file.
Once installation succeeds, the pipeline can continue with code validation.
Run ESLint
Add:
- name: Run lint
run: npm run lint
This checks the source code according to your ESLint configuration.
If linting fails, the job can stop before testing or building.
Run React Tests
Next, execute:
- name: Run tests
run: npm test -- --runInBand
The exact test command depends on your project’s testing tools.
Therefore, use the script defined in your package.json.
Build the React Application
Finally:
- name: Build application
run: npm run build
If the build completes successfully, your React project has passed the basic CI workflow.
Upload React Build Artifact
You can also save the generated production files.
For a project that creates a dist directory:
- name: Upload build artifact
uses: actions/upload-artifact@v4
with:
name: react-production-build
path: dist/
If your project generates build/, update the path accordingly.
This gives your team access to the exact build generated by the CI pipeline.
Complete React GitHub Actions Pipeline
A more practical workflow may look like this:
name: React CI
on:
push:
branches:
- main
- develop
pull_request:
branches:
- main
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Checkout repository
uses: actions/checkout@v4
- name: Setup Node.js
uses: actions/setup-node@v4
with:
node-version: '20'
cache: 'npm'
- name: Install dependencies
run: npm ci
- name: Run lint
run: npm run lint
- name: Run tests
run: npm test -- --runInBand
- name: Build application
run: npm run build
- name: Upload build artifact
uses: actions/upload-artifact@v4
with:
name: react-build
path: dist/
If your React project does not use dist/, replace it with the correct build directory.
CI/CD for React Applications Using Vite
Many React projects use Vite as their development and build tool.
A typical package.json may contain:
{
"scripts": {
"dev": "vite",
"build": "vite build",
"lint": "eslint .",
"preview": "vite preview"
}
}
The CI pipeline can simply run:
npm ci
npm run lint
npm test
npm run build
Vite commonly places production files inside:
dist/
The pipeline can then deploy that directory.
Environment Variables in React CI/CD
Real-world React applications usually require different environment configurations.
For example:
Development
Staging
Production
Each environment may use different values for API endpoints, analytics settings, application names, feature flags, or other public configuration.
Instead of hardcoding values, the CI/CD pipeline can provide the appropriate environment configuration during the build.
Development and Production API Example
Development may use:
https://dev-api.example.com
while production uses:
https://api.example.com
Your pipeline can select the correct value depending on the target environment.
For example:
develop branch
↓
Development API
staging branch
↓
Staging API
main branch
↓
Production API
This separation reduces accidental environment mistakes.
Important Security Rule for React Environment Variables
Environment variables used during a React client build are not automatically secret.
A React application runs inside the user’s browser.
Therefore, values that become part of the JavaScript bundle can potentially be inspected by users.
Never place highly sensitive credentials such as:
Database Password
Payment Gateway Secret Key
Backend Private Key
Service Account Secret
Server Administrator Credentials
Private Signing Key
inside frontend code.
Keep true secrets on your backend server.
The React application should communicate with the backend through secure APIs.
Managing CI/CD Secrets
Although frontend applications should not contain backend secrets, deployment pipelines may still need private credentials.
For example, CI/CD may require authentication credentials to deploy the application.
Store these values inside your CI/CD provider’s encrypted secret storage.
A secure process looks like:
CI/CD Secret Storage
↓
Deployment Job
↓
Authenticate
↓
Deploy Build
↓
Job Ends
Restrict production secrets to trusted branches and deployment jobs.
React CI/CD with Different Environments
A professional application may use:
Development
Staging
Production
The pipeline can deploy each branch to the correct environment.
For example:
feature/*
↓
CI Only
develop
↓
Development Environment
staging
↓
Staging Environment
main
↓
Production Environment
This gives developers and testers a safer workflow.
Recommended React Branch Strategy
A simple branch strategy may look like:
feature/*
↓
develop
↓
main
Feature branches contain active development.
Next, completed features move to develop.
Finally, production-ready changes move to main.
Your CI/CD pipeline can assign different actions to each branch.
For example:
| Branch or Event | CI/CD Action |
|---|---|
| Pull Request | Lint + Tests |
| Develop | Lint + Tests + Build |
| Main | Full Build + Deployment |
| Release Tag | Production Release |
This approach prevents unnecessary production deployments.
Separate CI and CD Pipelines
Larger React projects should consider separating code validation from production deployment.
The CI workflow can run:
Pull Request
↓
Install Dependencies
↓
Lint
↓
Tests
↓
Build Verification
The deployment workflow can run later:
Merge to Main
↓
Production Build
↓
Upload Artifact
↓
Deploy
Separating the two workflows provides better control and security.
GitLab CI/CD for React Applications
GitLab also provides integrated CI/CD functionality.
GitLab pipelines are usually configured inside:
.gitlab-ci.yml
A React pipeline may include stages such as:
Install
↓
Lint
↓
Test
↓
Build
↓
Deploy
GitLab can be a convenient solution when the project already uses GitLab repositories.
Jenkins CI/CD for React Applications
Jenkins can also automate React builds and deployments.
A typical Jenkins workflow may perform:
Checkout Repository
↓
Install Node.js
↓
npm ci
↓
npm run lint
↓
npm test
↓
npm run build
↓
Deploy
Jenkins offers extensive customization.
However, teams usually need to manage the Jenkins server, plugins, runners, and security configuration themselves.
CI/CD with Docker for React Applications
Docker can make React CI/CD workflows more consistent.
Instead of depending entirely on the runner’s environment, teams can build applications inside containers.
A simplified workflow might look like:
Git Push
↓
CI Pipeline
↓
Build Docker Image
↓
Run Tests
↓
Create Production Image
↓
Push Image
↓
Deploy Container
This approach becomes especially useful when the React application is part of a larger containerized system.
Docker Multi-Stage Build for React
A simple example may look like:
FROM node:20 AS build
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build
A production setup can then copy the generated static files into an appropriate web-serving environment.
Multi-stage builds can help keep production containers smaller.
Automated React Testing in CI/CD
Testing should happen before deployment.
A mature React pipeline may include several levels of testing.
For example:
Lint
↓
Unit Tests
↓
Component Tests
↓
Integration Tests
↓
End-to-End Tests
↓
Production Build
However, not every project needs every test type.
Start with the tests that protect your most important application behavior.
End-to-End Testing for React Applications
End-to-end tests can simulate real user workflows.
For example:
Open Website
↓
Go to Login Page
↓
Enter Credentials
↓
Submit Login
↓
Open Dashboard
↓
Verify Content
Tools such as Playwright or Cypress can support this type of testing.
Because end-to-end tests can take more time, teams often run fast unit tests first.
React Test Coverage in CI
Some projects generate test coverage reports.
The pipeline might perform:
Run Tests
↓
Generate Coverage
↓
Upload Coverage Report
Coverage can help teams identify areas with little automated testing.
However, a high coverage percentage does not guarantee high-quality tests.
Testing important behavior is more valuable than chasing a percentage alone.
Caching Dependencies in React CI/CD
Installing dependencies on every pipeline run may take time.
Caching can improve CI performance.
A basic caching workflow looks like:
First Pipeline
↓
Install Dependencies
↓
Save Cache
Next Pipeline
↓
Restore Cache
↓
Install Required Changes
↓
Continue
CI platforms often provide built-in caching support for npm.
However, keep cache configuration tied to lock files so outdated dependencies do not remain indefinitely.
package-lock.json in CI/CD
The lock file plays an important role in consistent dependency installation.
You should generally commit:
package-lock.json
to your repository when using npm.
Then CI can run:
npm ci
This allows the pipeline to install the dependency versions defined by the lock file.
As a result, local and CI environments become more predictable.
Build Artifacts in React CI/CD
A build artifact is the output generated by your pipeline.
For React applications, this is commonly:
dist/
or:
build/
The exact folder depends on the build tool.
Artifacts can help with deployment, QA testing, release history, and debugging.
A typical process looks like:
Source Code
↓
npm run build
↓
Production Files
↓
Artifact Storage
↓
Deployment
React CI/CD Deployment Strategy
A production deployment should follow a controlled process.
For example:
Developer Creates Pull Request
↓
CI Runs
↓
Tests Pass
↓
Code Review
↓
Merge to Main
↓
Production Build
↓
Deploy
↓
Verify Application
This process helps reduce production errors.
Staging Before Production
Deploying directly from development to production is not always ideal.
A staging environment allows the team to test the application in a production-like environment first.
A safer workflow is:
Development
↓
CI Checks
↓
Staging Deployment
↓
QA Testing
↓
Approval
↓
Production
This approach becomes especially valuable for large applications.
What Happens When a React CI Pipeline Fails?
Suppose a developer introduces code that breaks a unit test.
The pipeline might look like this:
Developer Push
↓
npm ci ✓
↓
Lint ✓
↓
Tests ✗
↓
Pipeline Failed
Because the tests failed, the build and deployment stages do not continue.
The developer fixes the problem and pushes again.
New Push
↓
Lint ✓
↓
Tests ✓
↓
Build ✓
↓
Deploy ✓
This fast feedback is one of the biggest advantages of Continuous Integration.
Common React CI/CD Problems
React pipelines can fail for several reasons.
One common issue is a Node.js version mismatch.
Your local machine may use one Node.js version while the CI server uses another.
This can cause dependency or build problems.
Therefore, define a compatible Node.js version in your workflow.
npm ci Fails
If:
npm ci
fails, check your dependency files.
Common causes include an outdated package-lock.json, dependency conflicts, incompatible Node.js versions, missing private package authentication, or corrupted project configuration.
Fix dependency issues before continuing with tests or builds.
Lint Passes Locally but Fails in CI
This can happen because of configuration differences.
Possible causes include different Node.js versions, different dependency versions, platform-specific file naming, or files that were not committed correctly.
For example, case-sensitive filenames can behave differently across operating systems.
Always review CI logs carefully.
Tests Work Locally but Fail in CI
Tests may behave differently in CI because the environment is clean and automated.
Possible causes include missing environment variables, time-dependent tests, external network dependencies, unavailable APIs, incorrect mock configuration, or differences between local and CI environments.
Reliable tests should avoid depending unnecessarily on one developer’s machine.
React Build Fails in CI
If:
npm run build
fails, check the build logs.
Common causes include missing environment configuration, TypeScript errors, dependency issues, invalid imports, incorrect paths, or production-only configuration problems.
Fix build failures before allowing deployment.
Environment Variables Missing During Build
Suppose the application requires an API base URL.
If the CI environment does not provide it, the production build may fail or use an incorrect value.
Therefore, configure environment variables before running:
npm run build
Also remember that frontend environment variables should not contain true backend secrets.
CI/CD Pipeline Takes Too Long
Large pipelines can become slow.
To improve performance, run inexpensive checks first.
For example:
Lint
↓
Unit Tests
↓
Integration Tests
↓
Build
↓
Deployment
You can also use dependency caching, parallel jobs where appropriate, and separate CI from production deployment.
React CI/CD Best Practices
A reliable React CI/CD workflow should stay understandable and secure.
First, run fast validation before expensive tasks.
Next, keep Node.js and dependency versions consistent.
Use npm ci when appropriate for repeatable CI installations.
Keep your lock file in version control.
Additionally, protect production branches with required CI checks and code review.
Never put private backend credentials inside React bundles.
Finally, deploy only after tests and production builds succeed.
Protect the Main Branch
Your production branch should not accept unchecked code.
A recommended workflow is:
Feature Branch
↓
Pull Request
↓
Lint
↓
Tests
↓
Code Review
↓
Merge
Repository protection rules can require successful CI results before merging.
This adds another layer of quality control.
Do Not Deploy Every Commit to Production
A small commit to a feature branch does not need a production deployment.
A better strategy is:
Feature Branch
↓
Lint + Test
Develop
↓
Lint + Test + Build
Staging
↓
Build + Staging Deploy
Main
↓
Production Deployment
This keeps production releases controlled.
CI/CD for Small React Projects
Small applications do not need complicated DevOps infrastructure.
Start with:
npm ci
npm run lint
npm test
Once that works, add:
npm run build
Finally, connect the build to your hosting environment.
A simple pipeline already provides significant value.
CI/CD for Large React Applications
Large applications may require more advanced workflows.
For example, a mature React pipeline may include multiple environments, pull request checks, TypeScript validation, linting, unit testing, component testing, integration testing, end-to-end testing, production builds, artifact management, staging deployments, production approvals, monitoring, and rollback strategies.
However, complexity should solve real project problems.
Do not add pipeline stages only because another team uses them.
Recommended React CI/CD Pipeline
A practical pipeline can begin with:
npm ci
Next, run:
npm run lint
After that, execute tests:
npm test
Then create the production build:
npm run build
Finally, deploy the generated files.
The complete process looks like:
Checkout Repository
↓
Setup Node.js
↓
npm ci
↓
Lint
↓
Tests
↓
Production Build
↓
Store Artifact
↓
Deploy
This workflow is simple enough for beginners while still being useful for production projects.
Complete React CI/CD Workflow Example
Suppose a development team is preparing version 2.0.0.
The release process might look like:
Feature Development
↓
Create Pull Request
↓
Run Lint
↓
Run Tests
↓
Build Verification
↓
Code Review
↓
Merge to Main
↓
Create Production Build
↓
Deploy to Staging
↓
QA Testing
↓
Production Deployment
↓
Monitor Application
This creates a clear and repeatable path from development to production.

npm run build
It can then store or deploy the generated production files.
Can a React application deploy automatically?
Yes.
After tests and the production build succeed, a CI/CD pipeline can deploy the generated files to your hosting environment.
Should I use npm install or npm ci in CI?
For many npm-based CI environments, npm ci is a good choice because it installs dependencies according to the lock file and starts from a clean dependency state.
Can CI/CD run React tests automatically?
Yes.
The pipeline can run your configured test script whenever developers push code or create pull requests.
For example:
npm test
Should API secrets be stored in a React application?
No.
React applications run in users’ browsers, so values included in the frontend bundle may be visible.
Keep true backend secrets on your server.
Should every React commit deploy to production?
Usually, no.
A better workflow is:
Pull Request
↓
Lint + Tests
Develop
↓
Build + Development Deployment
Staging
↓
Staging Deployment
Main
↓
Production Deployment
This provides better release control.
Final Thoughts
CI/CD for React applications can transform a repetitive development and deployment process into a faster, more reliable, and more consistent workflow.
Without CI/CD, developers may repeatedly perform tasks such as:
Install Dependencies
Run Lint
Run Tests
Create Production Build
Upload Files
Deploy Website
With automation, the pipeline can handle most of these tasks.
A complete React CI/CD workflow may look like:
Developer Push
↓
Checkout Repository
↓
Setup Node.js
↓
Install Dependencies
↓
Run Lint
↓
Run Tests
↓
Create Production Build
↓
Store Artifact
↓
Deploy
If you are new to React CI/CD, begin with:
npm ci
npm run lint
npm test
Next, add:
npm run build
After the basic pipeline works correctly, gradually introduce environment management, build artifacts, staging deployments, automated end-to-end tests, branch protection, deployment approvals, and production monitoring.
Most importantly, keep the workflow easy to understand and maintain.
A good React CI/CD pipeline should help your team detect problems earlier, reduce manual work, create consistent builds, and release React applications with greater confidence.
