Source: indepth.dev

Angular is a popular front-end JavaScript library that helps developers create user interfaces. With its easy-to-use features, Angular can help you build complex and interactive web applications quickly and easily.

This guide is for beginner developers who want to get started with Angular. We’ll cover the basics of setting up a development environment, writing basic code, and building simple user interfaces. By the end of this guide, you’ll have the skills you need to start developing with Angular.

What is Angular?

Angular is a popular front-end JavaScript framework that helps developers build user interfaces more quickly and easily. It allows for declarative programming, which makes your code easier to read and understand. Additionally, it uses dependency injection, which allows for components to be organized into reusable chunks. This makes development more efficient and reduces the time needed to develop new features. An Angular interceptor is also available that can be used to add new functionality to your application without having to modify the source code. This is a great feature when you need to add features that are not directly supported by the framework.

  1.  Use the Angular CLI to scaffold your projects.
  2.  Use the ng-model directive to bind data to input fields.
  3.  Use the ng-repeat directive to loop through arrays or lists of data.
  4.  Use the ng-show and ng-hide directives to control which parts of a view are visible or hidden.
  5.  Use the ng-model-options directive to configure input field behavior.

Tips for Debugging and Optimizing Your Angular Applications

If you are new to Angular, or even more so if you are working on your first Angular application, then you will likely find yourself debugging and optimizing your code a number of times. In this article we are going to share some tips with you that will help make your life as a developer easier.

– Debugging. When debugging an Angular application, it is important to understand the difference between the ng-debug and ng-info directives. The ng-debug directive will disable all rendering (including DOM updates) while the ng-info directive will only show information about the current module, service, or controller. When debugging an application using the Chrome Developer Tools it is often helpful to set breakpoints in the code and use the Watch feature to automatically run the code when a specified condition is met.

When debugging an application, it can be helpful to set a watch for any changes made in components or services that you’re trying to troubleshoot. This can be done by adding [change] tags around those components or services and specifying a change trigger (such as when a property value changes).

Optimization. One of the most common tasks that developers have to do when building Angular applications is optimize them for performance. There are a number of different optimization techniques that can be used and it really depends on what kind of experience you have with JavaScript and web development. However, some general tips that may help include minifying your CSS and JavaScript files, removing unused dependencies, and applying modularity and best practices when building your code.
