These patches are no longer necessary with the current state of the type packages and the code within the repository. The types are now included in the already required babel.d.ts file for the relevant babel packages (currently: `@babel/core` and `@babel/generator`). PR Close #53441

// The following modules are declared to work around a limitation in tsc_wrapped's `strict_deps`
|
|
// check. Since Babel uses scoped packages, the corresponding lookup for declaration files in the
|
|
// `node_modules/@types/` directory follows a special strategy: the `@types` package has to be
|
|
// named `{scope}__{package}`, e.g. `@types/babel__generator`. When `tsc` performs module
|
|
// resolution for the `@babel/generator` module specifier, it will first try the `paths` mappings
|
|
// but resolution through path mappings does _not_ apply this special naming convention rule for
|
|
// `@types` packages, `tsc` only applies that rule in its `@types` resolution step. Consequently,
|
|
// the path mapping into Bazel's private `node_modules` directory fails to resolve, causing `tsc`
|
|
// to find the nearest `node_modules` directory in an ancestor directory of the origin source
|
|
// file. This finds the `node_modules` directory in the workspace, _not_ Bazel's private copy of
|
|
// `node_modules` and therefore the `@types` end up being resolved from a `node_modules` tree
|
|
// that is not governed by Bazel, and therefore not expected by the `strict_deps` rule.
|
|
// Declaring the modules here allows `strict_deps` to always find a declaration of the modules
|
|
// in an input file to the compilation, therefore accepting the module import.
