How to 🤔 force tsc to ignore node_modules folder? 📦

Are you tired of seeing those annoying errors from the node_modules folder when running your tsc build tasks? 😩 Don't worry, we've got you covered! In this blog post, we'll address this common issue and provide you with easy solutions to force tsc to ignore the node_modules folder. Let's dive right in! 💪

The Problem 😫

So, you're using tsc build tasks in your project and every time you run it, you encounter the same errors from the node_modules folder. It's quite frustrating, right? Here's a sneak peek of the errors you might be seeing:

node_modules/@types/node/index.d.ts(6208,55): error TS2304: Cannot find name 'Map'.
node_modules/@types/node/index.d.ts(6215,55): error TS2304: Cannot find name 'Set'.
node_modules/@types/node/index.d.ts(6219,64): error TS2304: Cannot find name 'Symbol'.
node_modules/@types/node/index.d.ts(6225,59): error TS2304: Cannot find name 'WeakMap'.
node_modules/@types/node/index.d.ts(6226,59): error TS2304: Cannot find name 'WeakSet'.

The Solution 🎉

To overcome this issue and force tsc to ignore the node_modules folder, you need to make some adjustments to your tsconfig.json file.

Open your tsconfig.json file and look for the exclude property. If you don't have one, go ahead and add it to the root level of your tsconfig.json file. Your tsconfig.json should now look something like this:

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "sourceMap": true,
    "strict": false,
    "noImplicitAny": false,
    "strictPropertyInitialization": false,
    "esModuleInterop": true
  },
  "include": [
    "src/*"
  ],
  "exclude": [
    "node_modules",
    "./node_modules",
    "./node_modules/*",
    "./node_modules/@types/node/index.d.ts"
  ]
}

Notice the exclude property? It's where the magic happens! By adding the node_modules folder to the exclude array, you're telling tsc to ignore this folder during compilation. 🙅‍♂️

What's Next? 🚀

Once you've made the necessary changes to your tsconfig.json file, save it and rerun your tsc build tasks. You'll notice that the errors from the node_modules folder magically disappear! 🎩💫
