Currently there are two entry points for the `@angular/language-service` package: - `@angular/language-service` This default entry point is for View Engine LS. Through the redirection of `main` field in `package.json`, it resolves to `./bundles/language-service.js`. - `@angular/language-service/bundles/ivy.js` This secondary entry point is for Ivy LS. TypeScript recently changed the behavior of tsserver to allow only package names as plugin names [1] for security reasons. This means the secondary entry point for Ivy LS can no longer be used. We implemented a quick hack in the module resolver (in the extension repo) to fix this, but the long term fix should be in `@angular/language-service`. Here, the `main` field in `package.json` is changed to `index.js`, and in the index file we conditionally load View Engine or Ivy based on the input config. This eliminates the need for multiple entry points. As part of this PR, I also removed all source code for View Engine and Ivy included in the NPM package. Consumers of this package should run the bundled output and nothing else. This would help us prevent an accidental import that results in execution of unbundled code.
