Pull request checklist

Please check if your PR fulfills the following requirements:

  • Tests for the changes have been added (for bug fixes / features)
  • Docs have been reviewed and added / updated if needed (for bug fixes / features)
  • Build (npm run build) was run locally and any changes were pushed
  • Unit tests (npm test) were run locally and passed
  • E2E Tests (npm run test.karma.prod) were run locally and passed
  • Prettier (npm run prettier) was run locally and passed

Pull request type

Please check the type of change your PR introduces:

  • Bugfix
  • Feature
  • Refactoring (no functional changes, no api changes)
  • Build related changes
  • Documentation content changes
  • Other (please describe):

What is the current behavior?

When generating a hydrateFactory, rollup may split the output into multiple files. As Stencil only outputs the content of the first file this results in a broken hydrate script.

/dist/hydrate/index.js

// ...
var _appFactoryEntry = require('./@app-factory-entry-5119d8cd.js');
require('punycode');


exports.hydrateApp = _appFactoryEntry.hydrateApp;
// ...

When running stencil build --prerender:

[39:02.7]  prerendering failed in 64 ms
[ ERROR ]  Hydrate Error
           Error: Cannot find module './@app-factory-entry-5119d8cd.js' Require

What is the new behavior?

By using the inlinedynamicimports option, rollup bundles to hydrate factory to a single file, and hydrate, --prerender work as expected.

Does this introduce a breaking change?

  • Yes
  • No

Testing

Tested with yarn link against failing project.

Other information

To reproduce:

  1. Clone Event Store Design System
git clone [email protected]:EventStore/Design-System.git
  1. Checkout update-stencil branch
git checkout update-stencil
  1. Install dependencies
corepack enable
yarn
  1. Attempt to build documentation site
yarn docs

  1. Observe failure.

  2. If you want to observe more directly, you can edit node_modules/@stencil/core/compiler/stencil.js on line 58112 to log rollupOutput, and see that there are multiple files.

  3. Using this PR, build a new version of stencil and link the build:

yarn link ~/path/to/stencil
  1. re-run docs build
yarn docs
  1. Observe success 🎉

--strictNullChecks error report

Typechecking with --strictNullChecks resulted in 2094 errors on this branch.

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

Hey @George-Payne 👋

Thanks for submitting this! Checking it out now, but running into some issues when going through the reproduction steps. Before and after using a version of Stencil with the changes in this PR I get a TS error:
TypeError: tag.content.at is not a function

This could very well be something I'm doing wrong on my end with the project setup. Could you provide some additional steps if any are necessary (i.e. any build or other commands needed before trying to build the docs) or a separate minimum reproduction to validate against?

Thanks in advance! Hopefully we can get this verified and addressed quickly!

Hi @tanner-reits

TypeError: tag.content.at is not a function

Couple of things to try:

  • Ensure your node version is >=16.10, or better yet, current LTS (18.13.0)
  • Between step 3 and step 4, run yarn build just to make sure that typedoc-plugin-usage is built.

a separate minimum reproduction to validate against?

Unfortunately I couldn't figure out what causes rollup to decide to start splitting the file, so couldn't make a minimum reproduction, it works fine on a clean yarn create stencil, rollup puts it all in one file. It could be just project size.
