Custom egg-bin for your team

You maybe need a custom egg-bin to implement more custom features if your team has develop a framework base on egg.

Now you can implement a Program sub class, and Command sub class to do that. Or you can just override the exists command.

Example: Add nsp for security scan

nsp has provide a useful security scan feature.

This example will show you how to add a new NspCommand and MyProgram to create a new egg-bin tool.

• Full demo: my-egg-bin

MyProgram

const Program = require('egg-bin').Program;

class MyProgram extends Program {
  constructor() {
    super();
    this.version = require('../package.json').version;

    this.addCommand('nsp', path.join(__dirname, 'NspCommand.js'));
  }
}

module.exports = MyProgram;

NspCommand

const Command = require('egg-bin').Command;

class NspCommand extends Command {
  * run(cwd, args) {
    console.log('run nsp check at %s with %j', cwd, args);
  }

  help() {
    return 'nsp check';
  }
}

module.exports = NspCommand;

my-egg-bin.js

#!/usr/bin/env node

'use strict';

const run = require('egg-bin').run;

run(require('../lib/my_program'));

Run result

$ my-egg-bin nsp

run nsp check at /foo/bar with []
