Managing Environment Variables in React Properly
Managing environment variables in React is crucial for maintaining secure and reliable applications across different environments. Common mistakes include using incorrect prefixes, exposing sensitive data, and improper configuration management. Proper practices involve using tool-specific prefixes, avoiding secrets in client-side code, and validating variables before use.
- ▪Environment variables in React must use specific prefixes like REACT_APP_ for Create React App and VITE_ for Vite to be accessible in the client code.
- ▪Client-side environment variables are embedded in the browser bundle and should never contain secrets such as API keys or credentials.
- ▪Using .env.local and adding environment files to .gitignore helps prevent sensitive configuration from being committed to version control.
