node-di-modules

Simple helper to create module specification objects for node-di. It gives you two methods to add modules to the container. The first one, .add(), is nothing more than just setting modules[moduleName] = [type, module] manually. The reason why I built this is the second method, .addDir(), which dynamically requires all *.js files in the given folder and adds them to the module container, using the file name as the module name and assuming type = 'factory'.

Installation

npm install di-modules

Usage

var di = require('di');
var modules = new (require('di-modules'))();

modules.add('fs', 'value', require('fs'));
// directory paths must be relative to __dirname of the calling file
modules.addDir('./src'); // contains myModule.js and yourModule.js, which must be "factory" modules
modules.addDir('./src2', true); // recursively goes deeper into subdirectories
// add all node_modules entries (in the same directory as the calling file)
modules.addNodeModules();
// add specific modules by name
modules.addNodeModules(['events', 'express', 'async']);

// use di as if you filled the modules container manually
new di.Injector([modules]).invoke(async, fs, events, express, myModule, yourModule) {
  ...
});

Ideas

• .addDir() could support other module types than 'factory', either by specifying when calling it or by indicating it in the file name
