How to do module resolution in typescript to output for node?

Question

tsconfig.json

{
  "compilerOptions": {
    "baseUrl": "./",
    "allowJs": false,
    "strict": true,
    "target": "es6",
    "module": "commonjs",
    "lib": ["dom", "es6", "es5", "es2017", "esnext.asynciterable"],
    "sourceMap": true,
    "moduleResolution": "node",
    "paths": {
      "src/*": ["src/*"]
    },
    "declaration": true,
    "rootDir": "./src",
    "outDir": "dist"
  },
  "exclude": ["dist"],
  "include": [ "src"]
}

Original Folder structure

src /
  util/
    getSomething.ts
  index.ts

Output Folder structure

dist /
  util/
    getSomething.js
  index.js

index.ts

import getSomething from 'src/util/getSomething';

package.json script

{
"build": "tsc && tspath -f",
"start": "node dist/index.js"
}

The build works but when I run start I get error. Is there a way to have a root based module resolution? I followed this example (just replacing ~ with src) and it is giving me this problem. Unless there is an alternative solution to tspath. https://haseebmajid.dev/blog/better-imports-with-babel-tspath

Note: I am using windows 10.

npm start

Error: Cannot find module './src\util\getSomething' Require stack: c:\apps\example-typescript-node\dist\index.js

I have resolved my problem. I had to ensure my rootDir was ./ not src. Then targeting index.js inside dist/src/ not dist/

tsconfig.json

{
  "compilerOptions": {
    "rootDir": "./"
  }
}

package.json

{
"build": "tsc && tspath -f",
"start": "node dist/src/index.js"
}
