The Angular Language Service package is now tested & compiled using ESM. Previously it was a mismatch of CommonJS and ESM. Still the language-service ESM output is transformed into a single UMD bundle to allow for module resolution to be overriden. See `bundles/BUILD`. This is kept as is. To fully ship ESM (language-service is an exception here), we need to: * Update all code to no longer reference typescript via import. Instead typescript needs to be passed around so that the extension can control the version * The VSCode extension/ the TS server needs to be able to load ESM. It looks like the server supports ESM global plugins, but the extension might not yet. This is out of scope for the dev-infra effort as it requires more insight into VSCode & the extension system & the TS language server. PR Close #48521
