Detect Errors and Potential Problems in JavaScript

Posted · Category: Code, License Free, Tools

JSHint is a community-driven tool to detect errors and potential problems in JavaScript code and to enforce your team’s coding conventions. It is very flexible so you can easily adjust it to your particular coding guidelines and the environment you expect your code to execute in. The goal is to help JavaScript developers write complex programs without worrying about typos and language gotchas.

Any code base eventually becomes huge at some point, and simple mistakes–that would not show themselves when written–can become show stoppers and waste hours of debugging. And this is when static code analysis tools come into play and help developers to spot such problems. JSHint scans a program written in JavaScript and reports about commonly made mistakes and potential bugs. The potential problem could be a syntax error, a bug due to implicit type conversion, a leaking variable or something else.

Easily Organize Your Code Snippets with GistBox

Posted · Category: Code, License Free

GistBox is the beautiful way to organize code snippets. Your library is saved to the cloud for backup. Never worry about snippets getting lost in the shuffle. GistBox was built on standard HTML5 technologies. On the go or at the office, you’ll always have GistBox.

GistBox uses GitHub’s backend but adds its own layer of label and search functionality. It was designed to be a curated, personal snippet library – like long term memory for the practicing software engineer. Multiple instances of GistBox will sync with each other in realtime. Change code once, see it everywhere.

Interactive Challenges & Writing jQuery in the Browser

Posted · Category: Code, License Free

Try jQuery is a combination of videos, interactive console challenges, and writing code in the browser. You’ll need about 2 hours of time to make it through everything. There is a gentle introduction to what jQuery is, and what it can do.

It tells you how to search and walk through the DOM with selectors and traversing. Add & remove from the DOM, more traversing, and user events. Listen for events, handle them, and change the default event behavior of web browsers. Before landing, tame CSS with jQuery and animate elements on the page.

How to Optimize Your Code in JavaScript

Posted · Category: Code, Information

This article recently appeared on BuildNewGames.com, a collaboration by the teams at Bocoup and Internet Explorer. It is authorized to publish on WebAppers.

At Bocoup, my colleagues and I often laze about in antique leather armchairs, sipping Mai Tais, waxing rhetoric about important issues-of-the-day including international politics and automatic semicolon insertion. One thing I find fascinating is how people working on different types of projects have different wisdom to share: best practices for jQuery plugins are different than those for Facebook apps, and tips for Backbone.js ecommerce sites may not be useful when developing real-time strategy games.


What I’d like to share in this article is some code organization tips and tricks I’ve learned while making HTML5 games. I’ve tried to keep them as generally useful as possible, but you’ll definitely get the most out of this if you make games like I do.

First I’ll discuss organizing JavaScript code into files and modules. Then I’ll talk about code sharing approaches such as component systems. Lastly I’ll share some ideas for writing data-driven code in games.

Check HTML Source Code Conforms to Coding Standard

Posted · Category: BSD License, Code

HTML_CodeSniffer is a client-side script that checks HTML source code and detects violations of a defined coding standard. HTML_CodeSniffer is written entirely in JavaScript, does not require any server-side processing and can be extended by developers to enforce custom coding standards by creating your own “sniffs”.

HTML_CodeSniffer will provide a list of known and potential violations to the calling script. It also comes with a pop-up auditor interface, accessible via a bookmarklet, letting you browse through messages emitted from one of the defined standards. Where possible, the auditor also points you to the HTML element causing the problem. HTML_CodeSniffer is released under a BSD-style licence.

Online CSS Sandbox & Google’s Code Playground

Posted · Category: Code, License Free

CSSDesk is an Online CSS Sandbox. It allows people to quickly test snippets of CSS code, and watch the result appear live. I had very high ambitions for the project. There are line numbers and syntax highlighting appear live in the text box as you type. One of the greatest things is that it allows users to share their code with others as well.

And also, if you haven’t heard about Google’s Code Playground, it’s a web-based tool that lets web developers try out all of the APIs that Google provides, tweak the code, and see the results. Google’s Code Playground lets you play around without opening an external editor, and all of the APIs are loaded for you in the Pick an API box.

Repo.js is a jQuery plugin that lets you easily embed a Github repo onto your site. This is great for other plugin or library authors that want to showcase the contents of a repo on their project pages.

Repo.js uses Markus Ekwall’s jQuery Vangogh plugin for styling of file contents. Vangogh, subsequently, utilizes highlight.js, written by Ivan Sagalaev for syntax highlighting.

Open Source Code Editor Built on Top of HTML, CSS & JS

Posted · Category: Code, MIT License

Brackets is an open-source editor for web design and development built on top of web technologies such as HTML, CSS and JavaScript. The project was created and is maintained by Adobe, and is released under an MIT License. What makes Brackets different from other web code editors?

Instead of cluttering up your coding environment with lots of panels and icons, the Quick Edit UI in Brackets puts context-specific code and tools inline. With Live Development, Brackets works directly with your browser to push code edits instantly, set breakpoints, and jump back and forth between your real source code and the browser view.
