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 comments from the original code, which could aid attackers.

How can I secure my source maps?

You can secure source maps by restricting access to them, using server-side configurations, or by not deploying them in production environments.

Are there any tools to help with source map security?

Yes, tools like Sentry and Rollbar can help manage and secure source maps, ensuring they are only accessible to authorized users.
