Checking a TypeScript project with various start points for linting

Within my extensive application that is constructed using webpack, there are numerous entry points that are generated dynamically. Each entry point requires specific target files to be created during the build process.

I have already realized that when building, ts-loader must be utilized with just the transpileOnly option enabled. However, I am facing difficulties on how to use tsc to verify for any type errors.

My initial idea was to simply run tsc --noEmit ./**/*.ts after running 

tslint --config tslint.json ./**/*.ts
in my npm lint script. Unfortunately, this approach does not work because tsc does not support wildcards. There must be a straightforward solution out there, but I have yet to discover it.

Answer №1

To avoid code emission when transpiling with ts-loader, simply add the following configuration to your tsconfig.json:

{
  "compilerOptions": {
    "noEmit": true,
    /* ... */
  },
  "include": [
    "your-source-directory"
  ]
}

After making this change, you can simplify your npm script by running just tsc.

"scripts": {
  "type-check": "tsc"
}
