Note: Bugfender now has automatic mapping in beta. If you'd like to help testing it, please contact support for access.

When building a Javascript app, sometimes the source code goes through a series of transformations, such as obfuscation (sometimes called "uglifying"), minification, or source-to-source compilation (or transpilation). This process makes the final code less readable, so a file called source map can be generated to find out the original names of functions, file names and line numbers in case you need to.

When you're debugging an application, you can use these source maps to map stacktraces, for example.
