100+ Awesome Web Development Tools and Resources

The best and worst thing about being a web developer is that the web is constantly changing. While this is exciting it also means that web developers must always be proactive in learning new techniques or programming languages, adapting to changes, and be willing and eager to accept new challenges. This could include tasks such as adapting existing frameworks to meet business requirements, testing a website to identify technical problems, or optimizing and scaling a site to better perform with the backend infrastructure. We thought we would compile a comprehensive list of web development tools and resources that can help you be more productive, stay informed, and become a better developer.

A lot of these web development tools below are ones we use at KeyCDN on a daily basis. We can't include everything, but here are a couple of our favorites and other widely used ones. Hopefully, you find a new tool or resource that will aid you in your development workflow. The tools and resources below are listed in no particular order.

JavaScript libraries

JavaScript is one of the most popular programming languages on the web. A JavaScript library is a library of pre-written JavaScript which allows easier access throughout the development of your website or application. For example, you can include a copy of Google's hosted jQuery library by using the following snippet.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>

jQuery: A fast, small, and feature-rich JavaScript library.

BackBoneJS: Give your JS app some backbone with models, views, collections, & events.

Frontend frameworks

Frontend frameworks usually consist of a package that is made up of other files and folders, such as HTML, CSS, JavasScript, etc. There are also many stand-alone frameworks out there. We are a big fan of Boostrap and the main KeyCDN website is built on it. A solid framework can be an essential tool for frontend developers.

Web application frameworks

A web application framework is a software framework designed to aid and alleviate some of the headache involved in the development of web applications and services.

Ruby: Ruby on Rails is a web-application framework that includes everything needed to create database-backed web applications, with the MVC pattern.

AngularJS: Lets you extend HTML vocabulary for your web application. AngularJS is a framework, even though it's much more lightweight and sometimes referred to as a library.

Task runners / Package managers

Tasks runners are all about automating your workflow. For example, you can create a task and automate the minification of JavaScript. Then build and combine tasks to speed up development time. Package managers keep track of all the packages you use and make sure they are up to date and the specific version that you need.

Grunt: JavaScript task runner all about automation.

Gulp: Keeps things simple and makes complex tasks manageable, while automating and enhancing your workflow.

npm: Pack manager for JavaScript.

Bower: A web package manager. Manage components that contain HTML, CSS, JavaScript, fonts or even image files.

Languages / Platforms

Behind all the web development tools is a language. A programming language is a formal constructed language designed to communicate with a computer and create programs in which you can control the behavior. And yes we realize some of these might not always be referred to as a language.

PHP: Popular general-purpose scripting language that is especially suited to web development.

Code sharing / Code experimenting

There is always that time when you are on Skype or Google hangout with another developer and you want him or her to take a quick look at your code.
