Article 9: Modern Deployment and CI/CD for React Apps — Featuring GitHub Actions, Cloudflare Pages, and Workers

Learning Objectives

By the end of this article, you will:

Know how to automate building, testing, and deploying React apps using modern CI/CD pipelines.
Understand best practices for seamless, zero-downtime deployment—fit for both startups and industry giants.
Confidently deploy React projects to Cloudflare Pages and harness Cloudflare Workers for backend and edge logic (with special tips for fans!).
Practice DevOps skills that recruiters and top teams value.

Why Modern Deployment and CI/CD?

Shipping features fast isn’t enough—your app needs to reach users reliably and safely, every time. With Continuous Integration and Continuous Deployment (CI/CD), every code change is automatically tested and published. For Indian developers, this shift means less worrying about “deployment-day disasters,” and more productivity as a team.

Cloudflare Pages and Workers are changing the game—offering global scale, security, and edge computing, often for free.

Overview: Deployment Options for React in 2025

Cloudflare Pages: Jamstack-friendly, instant global edge deployment, zero config, free tier for hobby to pro.
Cloudflare Workers: Run backend code/functions “at the edge” for lightning-fast APIs alongside your static front-end.
Vercel and Netlify: Also popular for React, with automatic deployments from Git.
AWS Amplify, Azure Static Web Apps: Enterprise-oriented alternatives.
GitHub Actions: The CI/CD system that ties it all together—build, test, and deploy from your repo.

End-to-End Deployment Flow

Push code to GitHub (or GitLab/Bitbucket).
GitHub Actions runs tests, builds the app, lints code, and optionally deploys artifacts.
Cloudflare Pages (or Vercel/Netlify) picks up your branch, builds, and deploys globally.
Preview URLs for every pull request, ensuring safe reviews before going live.

Deploying to Cloudflare Pages: The Developer’s Dream

Why Choose Cloudflare Pages?

Seamless GitHub integration—auto-deploy on every push.
Indian users (and global!) get fast, secure experience thanks to Cloudflare’s edge.
Preview deployments for QA, pull requests, and team review.
Zero config: works out of the box with React (Vite, Next.js, CRA, etc.).

Quick Start

Create your React app locally (Vite, Next.js, or any modern setup).
Push it to GitHub.
Connect your repo to Cloudflare Pages:
- Go to Cloudflare dashboard → Pages → Create Application → Connect to Git.
- Choose your repo, set build command (npm run build), and build directory (dist for Vite, build for CRA).
Cloudflare auto-builds and deploys on every git push—including to preview branches.
Share your live app at: https://your-app.pages.dev

See Cloudflare’s docs for React setup for more details.

Using Cloudflare Workers with React

Workers let you run serverless code (e.g., APIs, authentication, routing) right beside your static app, globally.

Typical Use Cases

Implement custom backend APIs (orders, chat, payments) with near-zero latency.
Modify responses “at the edge” (e.g., localization, A/B tests, analytics).
Run SSR/React Router logic via Workers for lightning-fast navigation (React Router Worker Guide).

How to Use

Build your React app with Vite or similar tooling.
Add Cloudflare Worker using Wrangler CLI:
- npm install wrangler --save-dev
- Configure via wrangler.toml for build/deploy.
Develop locally and deploy:
- Run and test your Worker functions alongside your React app.
- Deploy both static assets and API logic via the Cloudflare platform.
CI/CD ready: Connect to GitHub and automatically deploy with each commit.

Setting up CI/CD with GitHub Actions

GitHub Actions automates your workflow for React apps:

Build, test, lint on every push/PR.
Deploy to Pages, Vercel, AWS, or any platform automatically.
Enforce code quality with automated checks—no more manual releases!

Example: GitHub Actions Workflow for React + Cloudflare Pages

# .github/workflows/deploy.yml
name: Build and Deploy React App

on:
      push:
            branches: [main]
      pull_request:

jobs:
      build:
            runs-on: ubuntu-latest

            steps:
                  - uses: actions/checkout@v3
                  - name: Use Node.js
                    uses: actions/setup-node@v4
                    with:
                          node-version: 20
                  - run: npm ci
                  - run: npm run build
                  - name: Deploy to Cloudflare Pages
                    uses: cloudflare/pages-action@v1
                    with:
                          apiToken: ${{ secrets.CF_API_TOKEN }}
                          accountId: ${{ secrets.CF_ACCOUNT_ID }}
                          projectName: your-pages-project
                          directory: ./dist

Replace your-pages-project and secrets with your Cloudflare details for secure, automated deploys. See CI/CD pipeline with React & GitHub Actions for details.

Real-World Best Practices for Indian Teams

Preview Deploys: Use branch-specific previews for QA and stakeholder demos—no more “it works on my machine”!
Automate everything: Lint, test, build, and deploy—consistent quality.
Keep secrets safe: Use GitHub’s secrets manager for API keys and tokens.
Monitor and rollback easily: Cloudflare Pages keeps deployment history for quick fixes.

Cloudflare Workers: The Secret Super-Charge

Use Workers for:
- Lightning-fast REST/API endpoints (auth, search, webhooks)
- SSR for React Router v7
- Edge caching and smart routing
Full-stack feel—without servers!
Indian startups: Avoid expensive servers—run logic globally on-demand.

Practice Exercises

CI Pipeline: Set up a GitHub Actions pipeline that builds, tests, and deploys your React app to Cloudflare Pages.
Edge Function: Write a simple Cloudflare Worker that adds a custom HTTP header to your React app for analytics.
Preview Deploy: Push a pull request and check the preview deploy URL from Cloudflare Pages.

Project Idea

Professional Feature: Build and deploy an end-to-end e-commerce storefront:

Automated CI/CD with GitHub Actions, linting and testing.
Frontend on Cloudflare Pages, API logic on Workers.
Preview URLs for every PR. Bonus: India-specific currency formatting “at the edge” using a Worker.

Final Thoughts: Putting Your App in the World

There’s nothing as exciting as shipping your work to users—and nothing as empowering as knowing it’s always secure, up-to-date, and fast, thanks to the right deployment and automation stack. With Cloudflare Pages and Workers, you’re not just deploying—you’re delivering a world-class, resilient experience, every time.
