Question

I installed npm i @types/node but process still doesn't register as existing. What else do I need to do to have type definitions for node?

Answer 1

You not only have to install the types for node (ie npm i @types/node ), but you also have to list "node" under "types" in tsconfig.json

// example tsconfig.json
{
  "compilerOptions": {
    "module": "CommonJS",
    "target": "ES2018",
    "baseUrl": ".",
    "importHelpers": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "types": ["node"]
  }
}
