What is the current behavior?

The aliased path transformation logic for the dist-collection output target does not correctly account for the case where the imported file is a sibling of the importing file. In this case, the generated import path is missing the leading ./.

This was caused by changes in #4501

GitHub Issue Number: N/A

What is the new behavior?

In the case that a generated import path does not start with a ., a ./ will be pre-pended to the path

Does this introduce a breaking change?

  • Yes
  • No

Testing

A reproduction can be found here. Brief testing steps can be found in the repro readme.

Other information

This is also a problem in v3.4.1. We'll want to backfill this change to the v3 maintenance branch as well

--strictNullChecks error report

Typechecking with --strictNullChecks resulted in 1625 errors on this branch.

That's the same number of errors on main, so at least we're not creating new ones!

One quick question

src/compiler/transformers/map-imports-to-path-aliases.ts
// Note also that any relative paths as module specifiers which _don't_
// need to be transformed (e.g. `'./foo'`) have already been handled
// above.
importPath = importPath.startsWith('.') ? importPath : './' + importPath;

Is there ever a scenario where we could expect importPath to start with '..' here (e.g. '../foo/bar.ts')?

It can, but the conditional here will only prepend the ./ if the path is not already relative. Some scenarios:

  • ../my/import/path -> ../my/import/path (no change)
  • ./my/import/path -> ./my/import/path (no change)
  • my/import/path -> ./my/import/oath (was not relative, so we make it relative)

It's safe to do this because we check that the path TS resolves is not external (i.e. a part of node_modules) before any of this transformation stuff happens. So, by this point, we know the path needs to be relative

@tanner-reits I'm having trouble reproducing the warnings in this step:

  1. Run npm run build and observe bundling warnings for unresolved imports

Thus far, I've done the following (added additional detail in bold)

  1. Create a blank Stencil starter (npm init stencil component path-test)
  2. Install Ionic Framework (npm i @ionic/core) (npm ls @ionic/core returns v7.1.3)
  3. Add import '@ionic/core' to src/ my-component/ my-component.tsx
diff --git a/src/components/my-component/my-component.tsx b/src/components/my-component/my-component.tsx

@rwaskiewicz I'm a dummy and forgot you need to use some local builds of framework since there were some config changes they needed to make. There's a lot of steps, so I'll just create a repro and link that for testing purposes

@tanner-reits can you upload the tarball used to create the custom framework builds? I can't install deps in your reproduction case ATM due to that being missing

@rwaskiewicz Ugh I hate trying to link all the local build crap 🙄 I added that artifact and made a few tweaks so it should resolve correctly. Nuked my local package-lock.json and node_modules and things worked
