unimpl

• TypeScript todo(), unimplemented() and unreachable() functions
• Inspired by Rust todo!(), unimplemented!() and unreachable!() macros
• Can develop a project without type check errors

Install

npm i unimpl

Usage

import { todo, unimplemented, unreachable } from 'unimpl';

function function1(): string {
  const needToImplement = true;
  if (needToImplement) {
    return todo(); // Throws an error 'Not yet implemented'
  }
}

function function2(): string {
  const needToImplement = true;
  if (needToImplement) {
    return unimplemented(); // Throws an error 'Not implemented'
  }
}

function function3(): string {
  const needToExit = true;
  if (needToExit) {
    return 'Exit function here';
  }
  return unreachable(); // Throws an error 'Internal error: entered unreachable code'
}
