source-maps-debugging

Debugging TypeScript in the browser requires configuring source maps to map compiled JavaScript back to original TS files. This Skill guides you through tsconfig.json and build tool settings to align emitted JS with TS sources for accurate stack traces and breakpoints.

The best way to configure TypeScript source maps with webpack involves adjusting tsconfig.json and webpack settings to generate and consume mapping files. This ensures browser DevTools correctly resolves compiled bundle lines back to their original TypeScript source locations.

TypeScript breakpoints fail in browser DevTools when source maps are missing or misconfigured, preventing the debugger from mapping runtime JavaScript to TS files. You must enable correct source map generation and source root settings in your build tool configuration.

Yes, this source map configuration approach works with Vite, Rollup, and webpack. It guides you through the specific build tooling settings needed to emit source maps that correctly map TypeScript files to emitted JavaScript across these environments.

To map a runtime error in a compiled file like app.js back to the original TypeScript file, you need source maps. This Skill helps configure TS and build tool source map generation so stack traces display the original TS file and line numbers.

Yes, you can use TypeScript source maps for debugging in Node.js as well as the browser. This Skill configures source maps to bridge TypeScript source code with runtime JavaScript, enabling accurate stack traces and breakpoints in Node debuggers.
