Setting up TypeScript to function with Webpack's resolve.modules

Imagine having a webpack configuration that looks like this:

resolve: {
  extensions: ['.ts', '.tsx', '.js', '.jsx', '.json'],
  modules: ['my_modules', 'node_modules'],
},

You have a unique directory named my_modules that functions in a similar way as the standard node_modules directories. Most guides and queries regarding TypeScript integration with webpack's resolve.modules setting focus on absolute paths, rather than using a specific directory name like my scenario.

Is there a method to instruct TypeScript to recognize module resolution within webpack's resolve.modules configuration above? Specifically, for incorporating another custom directory (similar to node_modules)?

Answer №1

If you're looking to streamline your module imports, consider utilizing a combination of baseUrl and paths in your tsconfig.json. For detailed information, refer to the comprehensivedocumentation provided here.

An example presented in the documentation closely resembles your situation:

With "paths," you can create more complex mappings that include multiple fallback locations. Imagine a project setup where specific modules are located in one place while others are in separate directories. After a build process consolidates these modules, the project structure may appear as follows:

projectRoot
├── folder1
│   ├── file1.ts (imports 'folder1/file2' and 'folder2/file3')
│   └── file2.ts
├── generated
│   ├── folder1
│   └── folder2
│       └── file3.ts
└── tsconfig.json

The corresponding configuration within tsconfig.json would be:

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "*": [
        "*",
        "generated/*"
      ]
    }
  }
}

This setup instructs the compiler to search in two locations - baseUrl and generated/ for any module import matching the "*" pattern.

import ‘folder2/file3’

    - the wildcard captures the entire module name under the '*' pattern
    - first substitution attempt: ‘*’ -> folder2/file3
    - non-relative name result requires combining with baseUrl -> projectRoot/folder2/file3.ts.
    - File not found, move to second substitution
    - second substitution ‘generated/*’ -> generated/folder2/file3
    - non-relative name result requires combining with baseUrl -> projectRoot/generated/folder2/file3.ts.
    - File found. Process complete

In your scenario, consider using my_modules instead of generated/*:

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "*": [
        "my_modules/*",
        "*",
      ]
    }
  }
}
