Entry point

Zero dependency, simple typescript decorator that makes OOP-like execution easier for class-contained, asyncrhonous entry points.

This is specially oriented to node CLI apps, that need a "main" method that usually is asyncrhonous. But can be synchronous and the environment can be the browser alike.

Also, in case that you're running the process in NodeJS, you'll receive an args array, from process.

Examples

You'll need to enable experimental decorators via experimentalDecorators and Es6 target is recommended (Lower versions might lack builtin Promise objects):

{
  "compilerOptions": {
    "experimentalDecorators": true,
    "target": "ES6"
  }
}

Example of usage:

import entry from 'ts-entry-point'

/**
 * Classical entry point main class.
 */
@entry
class Main {
  static main(args: string[]) {
    console.log(`Hello wordl! arg count = ${args.length}`)
  }
}

See example.ts for more insight.

Right now the setup for the TS compiler constraints is quite loose, feel free to open a pull request to make the project more compatible across different setups.
