npm metadata mirror

Monitor NPM changes and keep an up-to-date mirror of modules metadata (not the whole data, i.e. including attachments info, but not attachments body).

This module is intended to be part of a wider project, so it may not be as generic as it could, but feel free to use it for your own needs.

Installation

Install this like any other node module.

If you don't know how to do it, you don't need a npm metadata mirror, do you ?

Usage

Module

Load module:

var mirror = require('npm-metadata-mirror');

Standard usage:

// Start mirroring to local Redis database
mirror();

Don't have Redis installed ? Oh dear, you should :-\ You can still store data in-memory, but that's not a very good idea:

// Start mirroring to memory
// Each time you start this, it will restart mirrorring from nothing
// Which means loading 6000+ modules in memory
// Again and again
// You're really sure you want to do this ?
mirror({
  "store": new mirror.store.Memory
});

Command line

npm-sync [options]

Options are all the available options passed to mirror function. Except for the store option, as it's the initialization of an object:

• --store.engine the standard engine used, can be "Memory" or "Redis", default is "Redis".
• --store.module the engine class will be loaded from this module, instead of default mirror.store.
• --store.options the options passed to the engine constructor.

Example:

# Redis is installed on a special port
npm-sync --store.engine=Redis --store.engine.options.port=12093

TODO

• Add options to Redis engine: host, port, authentication...
• Add tests.
• Add doc (like all the options available, how to build a custom engine, etc...).
• Use log4js
