How can I protect my API keys in a React application?
An example of an AI chatbot conversation about protecting API keys in React applications.
How can I protect my API keys in a React application?
To protect your API keys in a React app, avoid hardcoding them in your source code. Instead, use environment variables.
What are environment variables and how do I use them?
Environment variables are key-value pairs stored outside your code. In React, you can create a .env file and prefix your variables with REACT_APP_.
Is it safe to store API keys in a .env file?
Yes, it's safer than hardcoding, but remember to add the .env file to your .gitignore to prevent it from being pushed to version control.
What if I need to expose some API keys to the client?
For public APIs, you can expose keys, but consider using a proxy server to handle sensitive operations securely.
