Commander.js Decorators

Small library used to create Commander js command using Annotation.

Installation

$ npm install commanderjsdecorators

Usage

Create a class with @command annotation as well as a method with the @action annotation.

example

import { command, action } from "commanderjsdecorators";
import commander from "commander";

@command({
  commander: commander,
  title: "XYZ",
  description: "saying hello",
  options: [
    { title: "-h, --hello [name]", description: "say hello" },
    { title: "-z, --sleep", description: "going to sleep" }
  ]
})
export class hello {
  @action()
  action(cmd: string, options: commander.Command) {
      console.log("launching hello");
      if(options.hello){
        console.log("hello: " + options.hello);
      }
      if(options.sleep){
        console.log("sleep: " + options.sleep);
      }
  }
}

Import the class for side effects only in you main file

import "./hello";

//rest of your application

This is all you need. The reset of the commander configuration can be done the same as before. Any class with the annotation will automatically be picked up by commander.js ,will be displayed in the help and execute the action when called.

TODO

• Add additional help annotation
• Figure out what is still to do
