The Deno runtime that ChiselStrike server uses under the hood supports the V8 Inspector Protocol, which allows you to attach a debugger to a running application.

To activate the inspector, pass the --inspect flag as follows:

npm run dev -- --inspect

You will see the ChiselStrike server output something like:

Debugger listening on ws://
Visit chrome://inspect to connect to the debugger.

To attach a debugger, install Google Chrome, and go to the chrome://inspect URL, and pick the ChiselStrike server to attach to.


The inspector integration is currently useful for CPU and heap profiling. You cannot configure a ChiselStrike project as a workspace so you cannot set breakpoints to application code. This is a limitation in ChiselStrike server and will be lifted in a future release.
