Summary
Related to #62263
This removes the processing we do on bundles to inject the base path into bundles at runtime. Instead, bundles built by the
@kbn/optimizerpackage will now look for a public path defined on a key in a global object:window.__kbnPublicPath__. These keys are populated by the bootstrap.js script and map each entry point id to the directory containing all of the outputs for that webpack build.This unblocks efforts to use the brotli compression algorithm instead of gzip. This is necessary because brotli compression is slow, so we must do it at build time. This is only possible if we do not need to do any processing before serving the file to the client.
Unfortunately, this PR is mostly a "works by coincidence" situation, meaning that the integration between
@kbn/optimizerand the bundle serving and bootstrapping logic must align in order for this work. There's not a great way to test this directly, but it is covered by existing e2e test coverage.I would like to create unit tests for the
ui_render_mixinandbootstrap.jsscript, however it seems impractical to do so until these are migrated to the Kibana Platform.Checklist
