Any other ideas for this API?

It might be nice if we didn't have this scenario where 1/4 of the states is basically invalid and has an odd non-intuitive default. Maybe just throw when false/false and then the other 3 states are valid and understandable?

dev = True|False|None or something like that is one alternative, although the word "dev" in the API without "prod" in the API is confusing imo. Or type = "dev"|"prod"|None but I'd want a term better then "type".

Actually is this API simply a copy of npm_translate_lock? In which case we should do exactly as you have and my suggestion can be considered in rules_js v3 or something like that...

Yeah, it's just following the prod/dev API from npm_translate_lock. I agree that an API that excludes invalid states by design would be better for v3.

This current API does not allow a single BUILD to have a mix of these though, correct? If you wanted to include dev deps for some targets (such as tests) but not for others (such as libraries).

Would something such as :node_modules[__{dev,prod}] as the API also solve this?

It does allow a mix. You could write npm_link_targets() and npm_link_targets(prod = True) and npm_link_targets(dev = True) in the same BUILD if you wanted.

I was thinking you can't have multiple npm_link_all_packages() targets though...?

Do we need the npm_link_all_packages API changes in this PR at all?

I can't remember why I included the npm_link_all_packages changes originally; I guess just for parallelism with npm_link_targets. We're only using npm_link_targets(prod = True).

+            link_targets.append("//{}:{}/abortcontroller-polyfill".format(bazel_package, name)) if (not prod and not dev) or (prod and not True) or (dev and True) else None


This generated if ... is ugly and I'm pondering how else we can do it. I think we can generate something simpler.

Can't we just compute a few vars at the top of the method such as include_dev and include_prod? Then this will be if include_dev else None or if include_prod else None or blank (or if True else None instead of blank).

Yeah, something like that should be possible I think.

After taking another look, I don't think it is possible. The contents of this fragment depend on whether the package in question is a production or dev dependency for the bazel_package in question. I.e., it's not a simple include_dev / include_prod boolean for each package, but rather a matrix of bazel_package x link_alias, which we're encoding as a nested conditional.

There might be some other way to structure this, but it would require a more invasive change.

jbedard · 2025-01-03T20:56:30Z

IIUC this solves the issue where rules_js currently treats the lockfile dev flag incorrectly, but does not add the API suggested in #1879?

This is my suggested solution for #1879. I think it's orthogonal to the lockfile dev flag issue. The determination of dev versus non-dev is done per pnpm workspace member, based on the devDependencies arrays in pnpm-lock.yaml, not the dev flag.

            # make available to all build targets; this includes devDependencies
            "all_deps": all_deps,


Is this still used?

No, will remove.

jbedard · 2025-05-01T16:45:24Z

@jfirebaugh have you had a chance to make any updates here? Are you using the patch in your repo?

WDYT of npm_link_all_packages(name = "node_modules") simply producing additional targets instead of accepting the flags?

:node_modules__dev
:node_modules__prod

Or would that add more confusion with things like :node_modules/@types? 🤔

Then npm_link_targets(dev, prod) like you already have here when we're just returning a list of targets.

jfirebaugh · 2025-07-14T23:27:55Z

Still using this in our repo. Just updated the patch for 2.3.8 and removed the change to npm_link_all_packages's API.

jfirebaugh · 2025-07-14T23:31:42Z

Hmm, removing that breaks something for us. Will have to investigate later.

jbedard · 2025-08-08T04:47:45Z

@jfirebaugh this has been picked up in #2298, would you be able to test that out to see if it works for you?

jbedard · 2025-10-15T17:27:41Z

#2298 has merged, let us know if that is missing anything
