Avoid installing @types typings in dependencies

Can I prevent global typings from being included in installed dependencies?

I recently installed a local dependency, which led to the node_modules folder of that dependency being copied over. Within this node_modules folder are @types typings that clash with those already installed for the main project.

For example,

project-path/node_modules/local-dependency/node_modules/@types/react
conflicts with
project-path/node_modules/@types/react
.

Is there a way to instruct the TypeScript compiler to disregard the typings within that local dependency?

Answer №1

Another option is to include "skipLibCheck": true in the compiler settings.

Answer №2

Have you attempted to utilize an empty array in the types option?

{
  "compilerOptions": {
    ...,
    "types": []
  }
}

This will deactivate the automatic inclusion of types.

For further information, please refer to the TypeScript documentation.

Answer №3

One way to have more control over which files the TypeScript compiler includes is by using the include and exclude properties in your tsconfig.json file:

Check out this link for more information.

The "include" and "exclude"properties allow you to specify glob-like file patterns. You can use wildcards like * to match characters, ? to match any one character, and **/ to recursively match subdirectories.

You can customize your configuration further by specifying specific exclusions, such as excluding the node_modules directory:

{

    ...    

    "exclude": [
        "node_modules"
    ]
}

If needed, you can create a targeted glob pattern to exclude only the problematic dependencies, like node_modules, while still including other necessary files.

If you're facing conflicts with different versions of modules, consider updating your dependencies or app to ensure they both use the same version. This may require deleting existing npm modules and performing a fresh npm install to resolve conflicts and ensure a shared module version.
