Deploying a React App

1. Introduction

React is a JavaScript library that helps to easily build and manage UI components.
To provide the developed React app to users, deployment is necessary. Deployment refers to the process of uploading the application to a server and making it accessible to users. In this course, we will learn about various methods to deploy a React app.

2. Preparing for Deployment

Before deploying a React app, the following preparations are needed.

1. Code Cleanup and Testing: Before deployment, unnecessary parts of the code should be cleaned up, and functionality tests should be conducted.
2. Environment Configuration: Understand the differences between development and production environments, and set up the .env file as needed.

3. Creating a Production Build

To deploy a React app, a production build must be created. You can create a build using the following command.

npm run build

Executing this command will generate optimized files in the build folder. These files are the ones that will be deployed to the web server.

4. Deployment Options

There are several platforms available for deploying React apps. Here, we will introduce the most commonly used deployment options.

• Vercel
• Netlify
• AWS S3
• GitHub Pages
• Heroku

5. Deploying with Vercel

Vercel is a platform that allows for easy deployment of static sites and JAMstack applications. The process for deploying a React app with Vercel is as follows.

1. Create a Vercel account
2. Connect the project: Link your GitHub, GitLab, or Bitbucket account.
3. Select the project and deploy: Choose the desired React project and click deploy.

Vercel automatically creates and optimizes the build for deployment.

6. Deploying with Netlify

Netlify is also a platform that makes it easy to deploy React apps. The deployment process is as follows.

1. Create a Netlify account
2. Connect to your GitHub repository
3. Deployment settings: Configure the build commands and outputs.
4. Deploy: Click the ‘Deploy site’ button to deploy.

7. Deploying to AWS S3

AWS S3 is a service for file storage, capable of hosting the static files of a React app. The process of deploying to S3 is as follows.

1. Create an AWS account.
2. Create an S3 bucket: Define a name for the bucket and perform the deployment settings.
3. Upload React build files: Upload the content of the generated build folder to S3.
4. CORS settings and static website hosting: Activate CORS settings and static website hosting options.

8. Troubleshooting and FAQ

Here, we summarize common issues that may arise during deployment and their solutions.

• 404 Error: Check React routing settings.
• HTTPS Error: Verify the SSL certificate.
• API Call Failure: Check CORS policy.

9. Conclusion

Deploying a React app can be somewhat complex, but using various platforms can make it much easier. We hope this course helps you successfully deploy your React apps.
