Finding dead code in the typescript project

For finding "dead" code in a typescript project, I use package:
yarn add -D ts-prune

after installation, add a script to package.json file:

{
...
  "scripts": {
    "find-deadcode": "ts-prune"
  }
}

now use yarn find-deadcode it will find and shows all unused exports in a project

The script above will detect unused exports, even if they are used internally within the module. So you can remove export to make this code local only, or you can modify script to ignore this behavior:

{
...
  "scripts": {
    "find-deadcode": "ts-prune | grep -v '(used in module)'"
  }
}
