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I\'ve got an npm package with badly written, out of date typings.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

You can get the desired behavior with the paths option in the tsConfig It could look something like this:

{
    "compilerOptions": {
       ...
        "paths": {
            "*": [
                "src/*",
                "declarations/*"
            ]
        }
    },
    ...
}

With this config typescript looks for modules in src (there should be all the app source) and also in declarations, in the declarations folder I usually place my extra needed declarations.

To override the typings of a node module there are two options:

1. place a folder named like the module inside the declarations folder, containing a file called index.d.ts for the typings

2. place a declaration file, named like the module, inside the declarations folder

As a working example you can take a look at this repo https://github.com/kaoDev/react-ts-sample

An important hint by Bernhard Koenig:

The order of the paths matters. I had to put the path with my overrides before the path with the original type definitions so my overrides get picked up first. – Bernhard Koenig
