DEV: introduce Embroider behind a flag, and start testing in CI (#23005) Discourse core now builds and runs with Embroider! This commit adds the Embroider-based build pipeline (`USE_EMBROIDER=1`) and start testing it on CI. The new pipeline uses Embroider's compat mode + webpack bundler to build discourse code, and leave everything else (admin, wizard, markdown-it, plugins, etc) exactly the same using the existing Broccoli-based build as external bundles (<script> tags), passed to the build as `extraPublicTress` (which just means they get placed in the `/public` folder). At runtime, these "external" bundles are glued back together with `loader.js`. Specifically, the external bundles are compiled as AMD modules (just as they were before) and registered with the global `loader.js` instance. They expect their `import`s (outside of whatever is included in the bundle) to be already available in the `loader.js` runtime registry. In the classic build, _every_ module gets compiled into AMD and gets added to the `loader.js` runtime registry. In Embroider, the goal is to do this as little as possible, to give the bundler more flexibility to optimize modules, or omit them entirely if it is confident that the module is unused (i.e. tree-shaking). Even in the most compatible mode, there are cases where Embroider is confident enough to omit modules in the runtime `loader.js` registry (notably, "auto-imported" non-addon NPM packages). So we have to be mindful of that an manage those dependencies ourselves, as seen in #22703. In the longer term, we will look into using modern features (such as `import()`) to express these inter-dependencies. This will only be behind a flag for a short period of time while we perform some final testing. Within the next few weeks, we intend to enable by default and remove the flag. --------- Co-authored-by: David Taylor <david@taylorhq.com>

DEV: convert I18n pseudo package into real package (discourse-i18n) (#23867) Currently, `window.I18n` is defined in an old school hand written script, inlined into locale/*.js by the Rails asset pipeline, and then the global variable is shimmed into a pseudo AMD module later in `module-shims.js`. This approach has some problems – for one thing, when we add a new V2 addon (e.g. in #23859), Embroider/Webpack is stricter about its dependencies and won't let you `import from "I18n";` when `"I18n"` isn't listed as one of its `dependencies` or `peerDependencies`. This moves `I18n` into a real package – `discourse-i18n`. (I was originally planning to keep the `I18n` name since it's a private package anyway, but NPM packages are supposed to have lower case names and that may cause problems with other tools.) This package defines and exports a regular class, but also defines the default global instance for backwards compatibility. We should use the exported class in tests to make one-off instances without mutating the global instance and having to clean it up after the test run. However, I did not attempt that refactor in this PR. Since `discourse-i18n` is now included by the app, the locale scripts needs to be loaded after the app chunks. Since no "real" work happens until later on when we kick things off in the boot script, the order in which the script tags appear shouldn't be a problem. Alternatively, we can rework the locale bundles to be more lazy like everything else, and require/import them into the app. I avoided renaming the imports in this commit since that would be quite noisy and drowns out the actual changes here. Instead, I used a Webpack alias to redirect the current `"I18n"` import to the new package for the time being. In a separate commit later on, I'll rename all the imports in oneshot and remove the alias. As always, plugins and the legacy bundles (admin/wizard) still relies on the runtime AMD shims regardless. For the most part, I avoided refactoring the actual I18n code too much other than making it a class, and some light stuff like `var` into `let`. However, now that it is in a reasonable format to work with (no longer inside the global script context!) it may also be a good opportunity to refactor and make clear what is intended to be public API vs internal implementation details. Speaking of, I took the librety to make `PLACEHOLDER`, `SEPARATOR` and `I18nMissingInterpolationArgument` actual constants since it seemed pretty clear to me those were just previously stashed on to the `I18n` global to avoid polluting the global namespace, rather than something we expect the consumers to set/replace.
