In this article I will show you the Angular.js tips that will help your Angular.js application to run at its best. While there are plenty of Angular.js guides out there that can be used to help you get started, in my opinion the best Angular.js tips come from the developer who knows the framework inside and out.
The very first thing you need to do is make sure that your Angular.js codebase has all the prerequisites built-in. Some projects do not have prerequisites which will leave your application unable to run. In my experience these days, it’s rare to find a project that does not have a prerequisites system built-in. So if your project doesn’t have a prerequisite’s system then it’s probably a good idea to move it over to the next project.
When working with Angular.js applications, it’s a good idea to run your application through a continuous integration server. These types of servers to help ensure that you have the latest changes from the Angular.js team included in your source code.
One of the best Angular.js tips is to never modify the DOM directly. Modifying the DOM directly can make Angular.js crash. Therefore the best Angular.js tips suggest instead that you use directive objects to make your changes.
The problem with modifying the DOM directly is that when you modify an element on the page it will update the view. This is important in Angular.js because it needs to be able to know when a change has been made. As a result you should avoid doing direct DOM manipulation in Angular.js code. Direct manipulation of DOM nodes will cause a lot of confusion to the Angular.js framework.
Another Angular.js tip is to always use local variables. The use of local variables in Angular.js is essential because it helps avoid many common problems caused by scope pollution.
A common problem in Angular.js code is scope pollution. Scope pollution is, where the scope of an Angular.js directive or controller becomes polluted due to multiple accesses.
By having an Angular.js codebase that is dirty-cleaned you can avoid scope pollution problems. Angular.js is completely object oriented so any time you access an Angular.js object within your codebase you are doing a scope pollution.
While there are plenty of Angular.js tips to apply, I will provide you with two Angular.js tips that I use on a daily basis. The first is to never let your Angular.js code run without a debug toolbar. The second tip is to have at least one production build for every Angular.js application.
If you choose to build Angular.js extensions, you should avoid modifying your source code directly. Instead you should build your extension using a combination of templates and custom directives. When you build your extension, you should compile it to a precompiled extension to avoid modifying your source code directly.
As you can see these Angular.js tips apply to any type of Angular.js application, but particularly for people who build Angular.js extensions. Use these Angular.js tips and you’ll be well on your way to building Angular.js extensions in no time!
