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. declare module '@babel/core' { export * from '@types/babel__core'; } declare module '@babel/generator' { export { default } from '@types/babel__generator'; }
