[Question] Is `baseUrl` needed in `tsconfig.json` ?

[jeniabrook]

First of all big fan of what are you doing with "Monorepo Maestros"!

I've read your TypeScript docs and wondering if we need to have a baseUrl in the tsconfig.json file that references @repo/tsconfig?

Meaning:

// packages/logger/tsconfig.json file
{
  "$schema": "https://json.schemastore.org/tsconfig",
  "extends": "@repo/tsconfig/base.json", // Using our base config!
  "compilerOptions": {
    "tsBuildInfoFile": "node_modules/.cache/tsbuildinfo.json",
    "baseUrl": ".",
  },
  "include": ["."],
  "exclude": ["node_modules"]
}

If we don't need it, in which scenarios do we need it in monorepo? In conjunction with paths maybe?

You're correct, baseUrl tends to get used with paths but it also can be used for non-relative module names. Documentation here: https://www.typescriptlang.org/tsconfig#baseUrl
