Express NodeJs Implementation Of Escaped Fragment

escaped_fragment.js

//declarations
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var compress = require('compression');
//catch all get requests and determine if there is an escaped_fragment, if so reroute to a relative folder public/_escaped_fragment_/{}.html
//if you have more complex hashes than `#!Something` then you may have to mod this logic to suit your needs.
app.get("*", function (req, res, next) {
    if (req.query._escaped_fragment_) {
        //pull file from escaped fragments folder and serve it
        res.sendFile(__dirname + '/public/_escaped_fragment_/' + req.query._escaped_fragment_ + '.html');
    } else {
        //continue down the next express routes and get caught in static files or potentially other routes you have declared
        next();
    }
});
//serve static files from public
app.use(express.static('public'));
