Setting "typeRoots" in tsconfig.json for jest

[jangxyz]

I am trying to make vscode understand describe, it and etc for test files, but following the document on typescript did not help.

Googling around for couple of hours, I found out that setting compilerOptions.typeRoots option to something else prevents from finding jest types.

From the tsconfig docs:

By default all visible ”@types” packages are included in your compilation. Packages in node_modules/@types of any enclosing folder are considered visible. For example, that means packages within ./node_modules/@types/, ../node_modules/@types/, ../../node_modules/@types/, and so on.

If typeRoots is specified, only packages under typeRoots will be included.

typeRoots is currently set to "../.redwood", which I guess is mainly for types built by redwood like routes, but this is blocking the default behavior.

I have actually succeeded on removing errors by commenting out the typeRoots option.

(Which I guess means that I can't use named routes)

I don't know if I can set the default behavior of recursively searching for node_modules/@types, but I'm assuming setting only for the root directory will be fine for redwood?

...
  "typeRoots": ["../.redwood", "../node_modules/@types"],
...

This is the same issue with #1400 (comment) . I don't know if others are having same issues -- vscode errors seem to pop all over the place. If it is a common issue, I wonder if this can be included in the docs.

"typeRoots": ["../.redwood", "../node_modules/@types"], looks good to me. But I'd wait for @peterp and/or @dac09 to comment as well.

If they don't see any problems with this it should definitely be added to https://redwoodjs.com/docs/typescript#web

👍 This is the way.

@jangxyz Would you be keen to open a PR for this?

Ran into this as well and just wanted to make sure API's tsconfig isn't left out of the party :)
