dynmod

dynmod

Auto-installs npm (node module package) dependencies as needed.

Works both synchronous and asynchronous.

Stores npm packages per user (no need for sudo rights) but still makes packages available system-wide.

Handles multiple versions of npm packages, so despite being system-wide, so your projects can still link different versions.

Why?

• Asynchronous require rocks
• Not everyone likes to check out all the npm packages in all the project directories (time, disk space etc)
• Allows your project to install dependencies only when they actually use them.

Install

Global install makes it available for all of your projects plus it makes the command line version available system wide. Requires administrator permissions (sudo).

[sudo] npm install dynmod -g

Local install

npm install dynmod

API

Asynchronous

• require('dynmod').require(npm_module_name, function callback(err, module) {});
• require('dynmod').remove(npm_module_name, function callback(err) {});
• require('dynmod').list([npm_module_name, ]function callback(err, versions) {});

Synchronous

• var mod = require('dynmod').require.sync(npm_module_name);
• var mod = require('dynmod').remove.sync(npm_module_name);
• var mod = require('dynmod').list.sync([npm_module_name]);

Examples

Code requires latest (or most current locally installed version) of ExpressJS - asynchronous

var dynmod = require('dynmod');
dynmod.require('express', function (err, express) {
  var app = express();
  // ... my express app logic
});

Code requires a specific version of ExpressJS - asynchronous

var dynmod = require('dynmod');
dynmod.require('express@3.5.0', function (err, express) {
  var app = express();
  // ... my express app logic
});

Code requires a specific version of ExpressJS - synchronous

var dynmod = require('dynmod')
  , express = dynmod.require('express@3.5.0')
  , app = express();

Command line examples

dynmod install express

Install a specific version of express

dynmod install express@3.5.0

Remove an installed version of express

dynmod remove express@3.5.0

List installed versions of express

dynmod list express
