Usage

const Mod = require('rddx-mod');

let mod = Mod({
  path: __dirname,   // module files base path
  reload: true,      // set to true to auto reload module when it has been changed. default to false
  delay: 100,        // when module has been changed, auto reload it after a while. default to 100ms
});

// register modules
// mod.register('name', 'path to');
mod.register('a', './a');
mod.register('b', './b');
// register third-part package
// mod.register('name', 'package');
mod.register('express', 'express');
// specified dependencies, after one of the dependencies has been reloaded, will reload this module automatically
mod.register('c', './c', {dependencies: ['a', 'b']});

// unregister module, and remove cache
mod.unregister('a');

// reload module although it has not changed
mod.reload('a');

// use module
// get property
mod('a').name;
mod('a', 'name');     // will throws error if "name" does not exists
mod.get('a', 'name'); // will throws error if "name" does not exists
// call method
mod('a').hello(msg);
mod('a', 'hello')(msg);      // will throws error if "hello" does not exists or is not a function
mod('a').get('hello')(msg);  // will throws error if "hello" does not exists or is not a function
mod.call('a', 'hello', msg); // will throws error if "hello" is not a function

const hello = mod.bind('a', 'hello');
hello(msg);

// emit "reload" event when module has been reloaded
mod.on('reload', function (name, file) {
  // name: registered name
  // file: absolute file path
});

// emit "register" event when module has been registered
mod.on('register', function (name, file, pkg) {
  // name: registered name
  // file: absolute file path (if your register a package, this is the "package.json" file of the registered package)
  // pkg:  package name (if your are not register a package, pkg is null)
});

// emit "unregister" event when module has been unregistered
mod.on('unregister', function (name, data) {
  // name: registered name
  // data: cache data
});

// if you want to catch the event of specified module,
// listen "eventName moduleName" event,
// for example:
mod.on('reload a', function (name, file) {
  // when module "a" has been reloaded, will emit this event
});

mod.on('destroy', function () {
  console.log('has been destroyed');
});

// all of above events has the "before eventName" event
// for example:
mod.on('before reload a', function (name, file) {
  // before "reload a" event emit, will emit this event
});

// unwatch all files and destroy mod instance
mod.destroy();
