Typescript not ignoring node_modules

Question

My directory structure:

• frontend

  -- node_modules

• backend

  -- node_modules

• tsconfig.json

In my tsconfig.json, I have:

"exclude": [
    "frontend/node_modules", "backend/node_modules"
  ]

Still, I get errors from packages in node_modules.

What am I doing wrong?

Why "exclude" doesn't work:

"exclude" only prevents items from being included by "include"; it doesn't prevent them from being included via import statements or <reference>s. If you import [the module] levelup, and levelup imports leveldown, then excluding leveldown or node_modules won't have an effect. (reddit)

Maybe you should try the option --skipLibCheck.
