The Node Beginner Book » A comprehensive Node.js tutorial Using Google's Closure to Compile and Verify your JavaScript 7, Mar 2013 A large application is nearly guaranteed to come with an equally large amount of JavaScript attached to it. During development it makes sense to divide the JavaScript of the application into multiple sensibly named files both to make finding specific functionality in the code base easier, and to keep the file length to a reasonable size for readability/comprehension purposes. More importantly though, this allows you to build modular, reusable components by separating functionality and sharing common methods within the application. However, when it comes time to move your site to the production environment, this development processes' inefficiencies become noticeable in slow loading pages. The most obvious pitfall is the fact that having multiple different files means that new HTTP requests have to be issued for each file, bringing with it an additional round trip time. Introducing Google Closure The Google Closure Compiler is a tool designed to solve these problems.
Documentation JSHint is a program that flags suspicious usage in programs written in JavaScript. The core project consists of a library itself as well as a CLI program distributed as a Node module. More docs: List of all JSHint options · CLI flags · Writing your own reporter · FAQ Basic usage The easiest way to use JSHint is to install it as a Node program. To do so, simply run the following command in your terminal (flag -g installs JSHint globally on your system, omit it if you want to install JSHint in the current working directory): $ npm install jshint -g After you've done that you should be able to use the jshint program. $ jshint myfile.js myfile.js: line 10, col 39, Octal literals are not allowed in strict mode. 1 error If a file path is a dash (-) then JSHint will read from standard input. Configuration JSHint comes with a default set of warnings but it was designed to be very configurable. This setup allows you to have different configuration files per project.

repeatingbeats/invoke - GitHub TechCrunch - The latest technology news and information on startups Dos días de diseño y hacking en la web El viernes 24 y sábado 25 se llevó a cabo el evento Mejorando.la/Conferencia enfocado al diseño y desarrollo web con sede en México. Vivimos horas intensas de aprendizaje y nuevos conocimientos en las 10 conferencias y dos panel realizados en el transcurso del evento, lo genial fue que para quienes no pudimos estar en las sedes era posible ver el evento y participar por medio de redes sociales gracias al streaming.
