This PR updates the extension-cookiecutter to jupyterlab>=4.0.0a37 (with yarn3).

It includes the changes of https://github.com/jupyterlab/extension-cookiecutter-ts/pull/291 by @trungleduc.

It also adds some missing devDependencies which should allow yarn install using nodeLinker: pnpm.

some missing devDependencies

Do you know if that was because the cookiecutter setup was making explicit use of them, and expecting these dev dependencies to be installed via another dependency? For example via @jupyterlab/builder.

No, it is not explicit use.

• react is a peer dependency of @rjsf/utils, imported via @jupyterlab/settingregistry.
• @type/json-schema is also expected by @rjsf/utils, but I don't really understand why, for me it should be included in the package.
• yjs is a peer dependency of y-protocol
• the others are necessary to build the extension (probably for webpack): https://github.com/jupyterlab/jupyterlab/blob/a3a0e3e7abf75e53810ed7ff8037c439cbb07697/buildutils/src/ensure-repo.ts#L71-L81. But it seems that not all of them were necessary.

Still wondering why we need to explicitly list these devDependencies.

the others are necessary to build the extension (probably for webpack): https://github.com/jupyterlab/jupyterlab/blob/a3a0e3e7abf75e53810ed7ff8037c439cbb07697/buildutils/src/ensure-repo.ts#L71-L81. But it seems that not all of them were necessary.

Normally the extension code should not have to care about these webpack dependencies, since they are already dependencies of @jupyterlab/builder.

Asking because the same list of devDependencies can also be found in the extension template: https://github.com/jupyterlab/extension-template

This is due to stricter check of pnpm packager about dependency specifications.

[jtpio]

Maybe these devDependencies could be put behind a "use pnpm?" copier flag, to remove noise for extensions staying on the default jlpm?

Strict control also applies to the use of node-modules. By the way, extension-cookiecutter-ts generate an extension using node-modules: https://github.com/jupyterlab/extension-cookiecutter-ts/blob/0ba10b8e268135a9c4c0283c8498a5d8f4a62c8f/%7B%7Bcookiecutter.python_name%7D%7D/.yarnrc.yml#L3
