What are source maps and how do they affect security?

Source maps are files that map your minified code back to the original source code. They help in debugging but can expose sensitive information if not handled properly.

What kind of sensitive information can be exposed?

If source maps are publicly accessible, they can reveal variable names, function names, and even the structure of your code, which can be exploited by attackers.

How can I secure my source maps?

You can secure your source maps by restricting access to them, using a build process that doesn't expose them in production, or by removing them entirely from production environments.

Are there any tools to help with source map security?

Yes, tools like Webpack and Rollup can help manage source maps, and you can configure them to avoid exposing sensitive information.
