media_streamer.coffee

fs = require 'fs'
path = require 'path'
util = require 'util'
express = require 'express'
app = module.exports = express.createServer()

app.get '/', (req, res, next) ->
    music_path = path.join __dirname, 'music'
    fs.readdir music_path, (error, files) ->
        output = []
        for file in files
            output.push "<audio controls preload=\"auto\" autobuffer src=\"http://192.168.253.142:9001/play/#{file}\"></audio>"
            output.push '<br />'
        res.send output.join('\n'), {"content-type": "text/html"}, 200


app.get '/play/:file', (req, res, next) ->
    filePath = path.join __dirname, 'music', req.param 'file'
    stat = fs.statSync filePath
    
    res.header 'content-type', 'audio/ogg'
    res.header 'content-length', stat.size
    res.sendfile filePath
app.listen 9001
