Dizzy-Promisify-Bluebird

When you use Dizzy to perform dependency injection you could also want the things to use promises. For instance, using fs.readFile() can get you into a mess with callbacks. By leveraging Bluebird, you can make all node-style callback functions return promises. That call to fs.readFile() turns into fs.readFileAsync() and you've started a promise chain.

Overview

First, you will likely want to get Dizzy up and running.

var container, Dizzy;

Dizzy = require('dizzy');

Next, call the plugin and pass in your reference to Dizzy.

require('dizzy-promisify-bluebird')(Dizzy);

Make your container.

container = new Dizzy();

Finally, register some modules to be promisified.

// One module
container.register("fsAsync", "fs").fromModule().promisified().cached();

// Multiple modules
container.registerBulk({
    cryptoAsync: "crypto",
    globAsync: "glob",
    zlibAsync: "zlib"
}).fromModule().promisified().cached();

Want to use TypeScript?

import { default as Dizzy } from 'dizzy';
import { default as dizzyPromisifyBluebird } from 'dizzy-promisify-bluebird';

dizzyPromisifyBluebird(Dizzy);
container = new Dizzy();
// and then use your container.
