Description

TypeScript allows to modify module resolution using the paths configuration option on the compilerOptions object. The mechanics of this are described in https://www.typescriptlang.org/docs/handbook/module-resolution.html. This feature is necessary for avoiding the relative path hell by aliasing the root of the current project, and importing files relative to that root.

Currently imports that contain an alias from the paths configuration are reported with the "Cannot find module" error, even though tsc resolves them correctly.

Research direction

No source file, test, or entry point is named. Start by tracing how the plugin reports module-resolution diagnostics and compare its handling of tsconfig compilerOptions.paths with tsc; done means aliased imports no longer produce the "Cannot find module" error and the behavior is covered by a regression test.
