The Sources workspace combines raw protocol fidelity with original-source mapping and embedded language services, so navigation, refactoring, debugging, and live editing operate on one coherent project view.
- 01
Original-source and indexed source maps
- 02
Persistent, conditional, function, and instrumentation breakpoints
- 03
Live-edit preview and source regeneration
- 04
TypeScript navigation, refactoring, and WebAssembly disassembly
How it composes
From intent
to working system.
Connect
The client preserves raw V8 messages and target capabilities across the Inspector session.
Map
Indexed and ordinary source maps connect generated code, original sources, breakpoints, and edits.
Debug
Pause state, lazy variables, scopes, return values, run-to-cursor, blackboxing, and breakpoints stay synchronized.
Edit
Validation and regeneration adapters preview safe live edits before mutating the running target.
Quick start
Adopt this
capability.
Start with the primary module, then add the related packages only when the application needs those layers. Replace VERSION with the current NuGet version.
dotnet tool install --global Chrome.DevTools.Inspector --prereleasecdp-inspector --url http://127.0.0.1:9229# Open Sources, select the V8 target, and debug mapped code.Modules in this capability
Use one layer.
Compose the rest.
Source of truth
Read the module beside the complete system.
The implementation, samples, issues, and release notes stay in the parent repository so module details remain connected to the product architecture.
