13.1 Understanding source maps ¶

Source maps are files generated during the build process that associate minified or transpiled code with its original source. They are particularly useful for JavaScript and TypeScript applications using bundlers such as Webpack, Rollup, or Vite, where production code is optimized for size and performance. Without source maps, error stack traces reference the minified code, complicating issue identification. When uploaded to Telebugs and linked to a release, source maps allow automatic unminification, displaying errors with references to the original file, line, and code context.

To generate source maps, enable the appropriate option in your bundler configuration (e.g., set sourceMap: true).
