tsc creates src folder in dist

Question

I have this folder structure:

- src
 - subdir1
 - subdir2

This is my tsconfig.json:

{
  "compilerOptions": {
    "target": "es2015",
    "module": "commonjs",
    "sourceMap": true,
    "declaration": true,
    "outDir": "./dist",
    "rootDir": "./src",
    "strict": true,
    "types": [
      "mocha",
      "node"
    ]
  }
}

Calling ./node_modules/.bin/tsc results in this folder structure:

- dist
  - src
   - subdir1
   - subdir2
- src
 - subdir1
 - subdir2

Why is src included in dist?

Answer 1

I ran the same thing and in fact it is a building error. In my case, i needed to get information of a file that was outside of 'src'.

Therefore, the TSC created the dir 'src' because my code "needed" to access something outside the folder 'src'.
