What is the best way to prevent TSC from including the node_modules folder in my compilation

I have encountered a persistent issue that all previous solutions have failed to address. Here is the snippet from my tsconfig file that I believe should resolve the problem:

...
  "compilerOptions": {
    "skipLibCheck": true,
...
"exclude": ["node_modules/*"]

Despite these configurations, I continue to encounter TypeScript errors related to files in my node_modules directory. Adding "explainFiles": true only confirms their inclusion.

What am I overlooking here?

Below is the complete configuration:

{
  "forceConsistentCasingInFileNames": true, 
  "noImplicitReturns": true, 
  "noUnusedLocals": true, 
  "compilerOptions": {
    "target": "es2015",
    "explainFiles": true,
    "allowJs": true,
    "checkJs": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "forceConsistentCasingInFileNames": true,
    "strict": false,
    "module": "esnext",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "preserve",
    "lib": ["dom", "es2015", "es2020"],
    "baseUrl": "./",
    "paths": {
      "src/*": ["src/*"],
    },
    "types": ["jest", "chrome"]
  },
  "include": ["src", "test"],
  "exclude": ["node_modules"]
}

Answer №1

To assist you better, could you please share the complete package.json and tsconfig.json files so we can investigate the issue further?

Based on my own experience, considering your input, here are some potential solutions:

  1. Try clearing the TypeScript compiler cache and rebuilding your project - delete the node_modules/.cache and dist (or out) folders then recompile TypeScript

  2. Thoroughly check your tsconfig.json file for any errors

  3. Make sure that your tsconfig.json is placed in the root directory and properly referenced

I also came across this suggestion online: 4. If "noImplicitAny": true is set in your tsconfig.json, consider temporarily changing it to false to see if it resolves the problem

These are initial steps based on the information provided; feel free to try them out.
