VSCode - Lerna - Typescript - Monorepo Code Navigation

Question

We have a monorepo for all our Javascript related SDKs here at Sentry. https://github.com/getsentry/sentry-javascript

If you clone this repo, set it up properly with yarn install and then open any file like packages/node/src/backend.ts and try to jump to the implementation of another package like the function limitObjectDepthToSize that lives in the utils package.

First of all, if you did not build the project before (have all type definitions in place) this error pops up:

But even if you built everything before, CMD+Click on the function now always jumps to the built object.d.ts instead of what I really want is that it jumps to the implementation source file which can be found in packages/utils/src/object.ts instead of /packages/utils/object.d.ts.

My question now is, is our setup wrong, is there any option in VSCode or maybe tsconfig.json that fixes this code navigation?

Or is this a currently known limitation of VSCode in monorepo environments?

Any help is appreciated and I hope it's nothing really obvious I just missed, thanks!

Answer 1

Set declarationMap to true to generates a sourcemap for each corresponding '.d.ts' file. It will allow IDE to jump to correct line at implementation file.

TS Documentation:

We’ve also added support for declaration source maps. If you enable --declarationMap, you’ll be able to use editor features like “Go to Definition” and Rename to transparently navigate and edit code across project boundaries in supported editors.
