typescript - Exclude/overwrite npm-provided typings

Question

I've got an npm package with badly written, out of date typings. I've written my own typings and now I'm wondering if I can somehow exclude the original typings from the npm package. It's not a simple extension of interfaces, the originals are basically garbage at this point.

Using the exclude list in tsconfig.json does not work for this purpose of course, since it still loads files from node_modules even if you exclude that folder.

Answer 1

Create node_modules folder under your src, then put typings of module(s) you want to overwrite inside:

├── node_modules
│   └── ...
│
└── src
    ├── index.ts
    ├── ... your codes ...
    │
    └── node_modules
        └── <module-to-be-overwritten>
            └── index.d.ts

No need to modify compilerOptions in tsconfig.json.
