Pull request type

Please check the type of change your PR introduces:

What is the current behavior?

The dist-collection output target currently does not transpile path aliases defined in a project's tsconfig.json. Instead, the import paths are left unchanged and thus reference modules that cannot be resolved.

GitHub Issue Number: #2815

What is the new behavior?

A transformation step has been added as a part of the dist-collection output target that will transpile path aliases and convert them in to relative paths based on the output files from the TS compilation

Does this introduce a breaking change?

Yes
No

Testing

Unit tests have been added for the new transformer, and existing unit tests continue to pass. (Further testing will be possible once infrastructure is in place related to STENCIL-223).

E2E tests continue to pass (as consistently as they did before)

Validated output on test repos (including Ionic framework)

src/compiler/transformers/map-imports-to-path-aliases.ts

This commit adds a transformer to the transpilation process to resolve module imports and replace path aliases with auto-generated relative paths. Resolves issue reported in STENCIL-437

This commit adds code comments and tests for the import path TS transformer. It also reverts some temp changes in a previous commit

This commit updates the path alias transformation behavior to only occur on the written files for the `dist-collection` output target

Only downside to this approach is, for this target, we'll essentially end up transpiling each module twice. However, I ran a couple builds with this change and without and only seemed to affect Stencil build times within a project by a second or so (that testing was done with the framework code base)

I was able to see the same thing:

Last thing we should need to decide is how to handle this release/deployment. Basically if we feel like this can be merged directly, considered a breaking change for V3, or something we would want to keep behind a config flag.

Last thing we should need to decide is how to handle this release/deployment. Basically if we feel like this can be merged directly, considered a breaking change for V3, or something we would want to keep behind a config flag.

I think we should add a configuration flag to the collections output target for folks to try this out and report any issues to us. My thoughts are we do the following:

resolve comments from @alicewriteswrongs and I on this PR
Create a separate PR that targets this one that adds the flag
- We'll also want to update our internal doc for flags for V3
Create a sibling PR with the associated documentation

do you know which tsconfig.json this pulls in? I was trying to modify the one at ./tsconfig.json from here (which inherits from ../../../testing/tsconfig.internal.json) but modifying that file doesn't seem to affect this test - is it pulling in our root tsconfig.json maybe? idk I tried modifying that file and it doesn't seem to affect the test output either. Just asking to make sure we aren't coupling these tests to something unexpectedly

This was a good catch. I didn't actually need to pull in that config anymore with how we handled these tests so I just stripped that entirely.

so right now basically the TS stuff is all being mocked out anyhow right? I didn't quite realize that when I first read through the tests

src/compiler/transformers/map-imports-to-path-aliases.ts

This commit addresses some final feedback items. Only the final file extension will be removed from the generated import path rather than all extensions. Additional tests were added to test path generation for the supplied output directory locations. And a strict null check was resolved in the transformer visit callback

src/compiler/transformers/map-imports-to-path-aliases.ts

This commit fixes a small issue with the generated regular expression for removing generated path file extensions.

LGTM 👍 Gonna hold off on the official approval until we decide how we want to handle the child PR(s)

I think this looks good! 👍

* fix(compiler): add config flags for transpiling path aliases This commit adds config flags to enable the transpilation of import path aliases as a part of the `dist-collection` output target. Part of the work for STENCIL-437 * fix(compiler): update terminology from 'transpile' to 'transform' This commit updates the language for the config option of `dist-collection` from `transpileAliasedImportPaths` to `transformAliasedImportPaths`. This also adds validation logic and test coverage for the `validateCollection` function * fix(compiler): use `@example` JSdoc tag for code formatting * fix(compiler): test cleanup for `dist` targets This commit cleans up some test code for the `dist` and `dist-collection` targets * fix(compiler): fix overwrite race condition for `dist-collection` This commit fixes an overwrite race condition for duplicate `dist-collection` output targets writing to the same file location(s). * test(compiler): fix transform test normalization? * fix(compiler): use `normalizePath` util in path alias transformer

This implements a transformer which is very similar to the one added in #3523 but which is run earlier in the build process and which can therefore rewrite aliased paths in both emitted JS and typedef files. This matters if the user has the `generateTypeDeclarations` option set to `true` on one of their output targets. The new behavior implemented here, however, is no longer specific to a particular output target, and applies to all TypeScript code which runs through Stencil. Accordingly, the behavior is opt-in, and is controlled by a new configuration value, `transformAliasedImportPaths` which defaults to `false`.
