TSC cannot find name of Global Object

Question

In my typescript code I am trying to access the __dirname global object: https://nodejs.org/docs/latest/api/globals.html

I am seeing a compile error: TS2304:Cannot find name '__dirname'. I can run the code without any issue. How can I get tsc to compile without error?

Answer 1

In tsconfig.json add "node" to compilerOptions.types.

Example:

{
 "compilerOptions": {
  ...
  "types": [
    "node"
  ]
  ...
  }
}

Then run npm install @types/node --save-dev
