How do I set up environment variables for a React app?
To set up environment variables in a React app, you need to create a file named .env in the root of your project.
What format should I use for the variables in the .env file?
You should use the format REACT_APP_YOUR_VARIABLE_NAME=value. For example, REACT_APP_API_URL=https://api.example.com.
How do I access these variables in my code?
You can access the variables using process.env.REACT_APP_YOUR_VARIABLE_NAME. For example, const apiUrl = process.env.REACT_APP_API_URL;.
Do I need to restart the server after adding new variables?
Yes, you need to restart your development server for the changes to take effect.
