Node.js et NPMDe la gestion de dépendances à la publication de packages
NodeJS
- Environnement d'exécution asynchrone- Basé sur V8 - Permet d'utiliser Javascript côté serveur- Mais surtout ...
Une communauté très active !
NPM
- Gestionnaire de paquets (Equivalent de pip en python ou gem en Ruby)- Registry (annuaire, moteur de recherche)- Basé sur un manifeste (package.json)

grunt.loadNpmTasks('grunt-contrib-coffee'); grunt.registerTask('default', ['coffee']);};
Cake - Cakefile$ npm install -g coffee-script$ cake build
task "build", "Compile coffee files to JS", ->
console.log "Compile main file..." command = "coffee -c main.coffee" exec command, (err, stdout, stderr) -> if err console.log "Error: \n #{err}" process.exit 1 else console.log "Compilation succeeded."
