fix(compiler): reorder tsconfig#path transforms #4501

rwaskiewicz · 2023-06-21T19:21:20Z

What is the current behavior?

In very specific circumstances, Stencil might not detect the correct h and Host functions as a result of transforming import paths specified in tsconfig.json#paths (see testing section).

GitHub Issue Number: N/A

What is the new behavior?

this commit reorders the transformations run for rewriting paths to
modules in import statements.

previously, modules in import statements would be rewritten based on
the contents of tsconfig.json#paths before any other transformation
was run. this would conflict with the updateStencilCoreImports
transformation if @stencil/core (or any of its valid subpaths) were
listed in tsconfig.json#paths. this would cause the wrong versions of
helpers such as h and Host to be picked up when a project used the
--prerender flag on a component that imported either of the above
helpers (the lazy output target version would be inlined to the output
rather than the hydrate version).

this commit removes the transformation run-program and places it
(conditionally) in the "before" transformers list after stencil
imports are transformed.

Does this introduce a breaking change?

Yes
No

Testing

I generated a dev build of this branch - @stencil/core@3.4.0-dev.1687377141.615ce97

Locally

The underlying issue can be reproduced by using https://github.com/rwaskiewicz/transform-import-paths

this reproduction expects that the location of a built stencil compiler to exist at ~/workspaces/stencil/bin/stencil.
if your local stencil exists at ~/dev/username/projects/stencil, update occurences of ~/workspaces with the parent directory of your stencil repo.

this project contains build and build-local scripts.
the former will run a build against your local stencil project, the latter against the version of stencil installed by npm.
when running without this PR built locally, we expect both to fail.
once this PR is built, build ought to work, while build-local continues to fail
if npm i @stencil/core@3.4.0-dev.1687377141.615ce97 is run, build-local will pass

likewise, without building this pr, npm run prerender will fail.
upon building it, npm run prerender will pass

Ionic Framework

Ionic Framework already uses the transformAliasedImportPaths and has a few paths in tsconfig.json set. With that in mind, the test here is that existing aliasing doesn't break when we exercise the entirety of the CI pipeline in Framework.

I created a temporary branch in the Ionic Framework repo that would run the stencil-nightly job with my dev build. Specifically, I applied this patch:

Noticed a couple discrepancies when testing:

(I think this might actually be behavior we want, just noting the difference). With this change, aliased paths aren't re-written for the dist-collection target when transformAliasedImportPaths is set. Instead, these paths only get transformed when transformAliasedImportPathsInCollection is set on the dist target or transformAliasedImportPaths is set directly on the dist-collection target.
Doesn't look like aliased imports in typedefs are getting transformed. I made a change in framework to add an aliased path to an interface used in a component but the path does not transform in the output in the dist/types directory like it does in v3.3.0

code looks straightforward, just had a few questions about it

should this function possibly be called getCustomBeforeTransformers? that would be consistent with the property added to BundleOptions I think

checking my understanding: this is because the updateStencilCoreImports transformer has to run before the rewriteAliasedSourceFileImportPaths transformer in order to avoid the reported bug?

Yup - exactly.

In the future it might be interesting to try to remove the need for updateStencilCoreImports and avoid subtle-ish bugs like this. I thought about pulling that thread, but felt that would have been much bigger in scope 😅

similarly I'm wondering if this should be getCustomAfterDeclarationsTransformers

I ended up removing these functions in 9b9eb7e

it makes sense that you had to put that back into the earlier pre-output target transformation since iirc it's in that run of the typescript compiler that we do declaration: true if you have certain options set, so I think adding a transformer for afterDeclarations wouldn't have an effect if it's added in the output target code

question: we have this same function copy-pasted essentially. does it make sense to try to carve out a getSharedCustomAfterDeclarationsTransformers function that would pull out the transfomers which are common to all of our output targets? Likewise we could maybe pull out shared logic for setting up the transformers which are shared by output targets for the before bit. Might be more trouble than it's worth though...

I thought about that - and I almost did it. @tanner-reits noticed that type transformations aren't working in all cases in Framework. I think I'm going to end up putting the afterDeclarations stuff back in run-program.ts, but need to do some testing first before I commit to that

Yup - removing these in 9b9eb7e

Instead, these paths only get transformed when transformAliasedImportPathsInCollection is set on the dist target or transformAliasedImportPaths is set directly on the dist-collection target.

That seems right to be, since we set that flag for DIST_COLLECTION when an OT has collectionDir set:

stencil/src/compiler/config/outputs/validate-dist.ts

Lines 66 to 72 in 1a2c160

    
           if (distOutputTarget.collectionDir) { 
        
             outputs.push({ 
        
               type: DIST_COLLECTION, 
        
               dir: distOutputTarget.dir, 
        
               collectionDir: distOutputTarget.collectionDir, 
        
               empty: distOutputTarget.empty, 
        
               transformAliasedImportPaths: distOutputTarget.transformAliasedImportPathsInCollection,

Doesn't look like aliased imports in typedefs are getting transformed. I made a change in framework to add an aliased path to an interface used in a component but the path does not transform in the output in the dist/types directory like it does in v3.3.0

Good catch! Fixed in 9b9eb7e

@tanner-reits @alicewriteswrongs Thanks for the feedback! Everything should be fixed/addressed!

alicewriteswrongs

all good! confirmed the issue w/ the reproduction (after a little trouble 😅) and then confirmed that the fix eliminates the issue

tanner-reits · 2023-06-23T13:43:08Z

Typedefs are working as expected again. 🚢 it!

this commit reorders the transformations run for rewriting paths to modules in import statements. previously, modules in import statements would be rewritten based on the contents of `tsconfig.json#paths` before any other transformation was run. this would conflict with the `updateStencilCoreImports` transformation if `@stencil/core` (or any of its valid subpaths) were listed in `tsconfig.json#paths`. this would cause the wrong versions of helpers such as `h` and `Host` to be picked up when a project used the `--prerender` flag on a component that imported either of the above helpers (the `lazy` output target version would be inlined to the output rather than the `hydrate` version). this commit removes the transformation `run-program` and places it (conditionally) in the "before" transformers list _after_ stencil imports are transformed.
