Mementoweb.js

This is an express 4.X routing plugin to easily add Memento Datetime versioning to your application. It is an implementation of RFC7098.

Install mementoweb.js via npm

npm install mementoweb

Create a simple application by specifying which Datetime Negotiation pattern you want to use (2.1 is default).

var express = require('express'), 
	memento = require('mementoweb');

var app = express();

var memento = memento(app,{pattern:21});

Create routes as with any other express application

app.get('/hello', function(req, res){
	res.send('Hello World');
});

var server = app.listen(3000, function() {
	console.log('Listening on port %d', server.address().port);
});

The resources /hello?memento=timegate, /hello?memento=timemap, /hello?memento={version} will be automatically available, together with the required hypermedia.
