This release includes various refinements and improvements. One thing if fixes is an issue where previously an exported class declaration that included a static property would be not have the export keyword put directly on the class declaration, but instead the symbol would be exported.

So with the following typescript:

export class MyClass {
  static foobar: string = "baz";
}

the compiler would emit code like this:

class MyClass {
  static foobar = "baz";
}
export { MyClass }

instead of

export class MyClass {
  static foobar = "baz;
}

The former output causes an issue with Rollup, so that issue being fixed is part of the impetus for this upgrade.

Try this out here on the TS playground to confirm (toggle between version 5.1 and 5.2 and look at the change in output).

See https://www.typescriptlang.org/docs/handbook/release-notes/typescript-5-1.html for a full list of changes and improvements.

Does this introduce a breaking change?

  • Yes
  • No

Testing

I built and packed Stencil locally with this change and then used it to build Framework without any issues. I'd suggest taking a look through the TypeScript release notes to see if anything jumps out that we should test specifically. Maybe try building a little sample project too!

--strictNullChecks error report

Typechecking with --strictNullChecks resulted in 1595 errors on this branch.

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

Nice! I wanna do some playing around with this, but have a few initial asks:

  1. Can we update the Renovate config to ignore TS 5.2?
  2. Can we update the doc site by adding this version of TypeScript to the support table? (I suppose this'd go under "Stencil 4.2.0"

@alicewriteswrongs there's a small chance we'll need to remove some of the workarounds I put in place a while ago for dealing with the issue you described in the PR summary. I think that's why the karma tests are failing

yeah, I'll look into that this afternoon

@alicewriteswrongs I think the attached patch file should get you most of the way - there's one karma test that's still failing I couldn't figure out just yet, but that patch ought to revert all of the workarounds we had to do for TS 5.0.

For posterity, these are what we need to (mostly) roll back

thanks for those patches! I made a change here to ensure that the export injection stuff we do is just limited a little bit to situations where we actually want to do it (to avoid a rollup error relating to double exports)

All in all, this looks good to me! I played around with the dev server (flashbacks from the TS 4.8/9 upgrade) to verify we weren't constantly reloading when doing unrelated FS activity (e.g. git status). I also ran this through the Ionic Framework locally, and couldn't find any errors. Also ran this through the Stencil/Framework nightly build, and couldn't find any issues there 😆

I have a couple minor suggestions/asks, LMK what you think!

  1. Can we update the Renovate config to ignore TS 5.2?
  2. Can we update the doc site by adding this version of TypeScript to the support table? (I suppose this'd go under "Stencil 4.2.0"

This might be a bit of a premature optimization, but since retrieveTsModifiers can call through to ts.getModifiers, which can allocate a new array on each call, it may be beneficial to extract this call into its own variable, so we don't end up doing this work here and down below when we attempt to figure out the opposite

Sure we can do that. I actually originally had let classHasExportKeyword = false; and then updated the variable in the .filter callback below but I thought it was too confusing and I didn't want to couple those two checks together like that, but I think pulling out const tsModifiers = retrieveTsModifiers(classNode) ?? []; into a separate call is a happy medium

For my own edification, are these changes necessary for the Karma tests to pass?

I think they were but I'll do a remove-and-replace to confirm the minimum that was needed

actually didn't need them! before applying that patch they got some of the karma test components to build, but with that patch they're not needed

No concerns on my end

This release includes various refinements and improvements. One thing if
fixes is an issue where previously an exported class declaration that
included a static property would be not have the export keyword put
directly on the class declaration, but instead the symbol would be
exported.

So with the following typescript:

```ts
export class MyClass {
  static foobar: string = "baz";
}
```

the compiler would emit code like this:

```js
class MyClass {
  static foobar = "baz";
}
export { MyClass }
```

instead of

```js
export class MyClass {
  static foobar = "baz;
}
```

The former output causes an issue with Rollup, so that issue being fixed
is part of the impetus for this upgrade.

Try this out [here on the TS
playground](https://www.typescriptlang.org/play?useDefineForClassFields=true&target=9&ts=5.1.6&ssl=1&ssc=1&pln=3&pc=1#code/KYDwDg9gTgLgBAYwDYEMDOa4GFUbgbwFgAoOMuNGFGASwTgDNoBbAQQwgRuuABM4AvHBhQArsADcJAL5A)
to confirm (toggle between version 5.1 and 5.2 and look at the change in
output).

for a full list of changes and improvements.
