So why not start exploring what the angular ecosystem has to offer today?

Building a Solid Foundation for Your Angular Application

To build a solid foundation for your Angular application, you should be familiar with TypeScript. TypeScript offers typing, which is not available in plain JavaScript. This means that you can write valid TypeScript code, which will be converted into valid JavaScript meaning that you can have maintainable code while minimizing bugs.

When building an Angular application, it is essential to use components as your building blocks. Each component includes a TypeScript class that defines the component's properties and methods. By using concise syntax and following best practices when creating these components, you can ensure that your code is easy to read, maintainable and scalable. By taking these steps to build a solid foundation for your Angular application, you will set yourself up for success in the long term.

Get familiar with your Angular application

When starting to work with Angular, it is essential to understand the structure of your application source files. This tutorial focuses on the appmodule.ts file, which acts as a central hub for your entire application. It specifies what components and services are included in your project.

The template determines the logic view of a specific component, while the style defines styles for that component. The app.component.ts and app.component.html file separates the structure of your application from its logic view.

To help manage all of these files and create new ones quickly, developers use the Angular CLI. The CLI generates automatically include files such as component testing called app.component.spec.ts. With just one command, the CLI creates a new component for you to start working on.

Get Your Application Ready for Use

To start building an AngularJS application, you can use the Angular CLI. This is a command-line interface that provides developers with various tools to create, generate, build, test and deploy Angular applications. To begin, navigate to your desktop directory and create an application called "todo" using the "ng new todo" command. This will create a minimal starter Angular application with some additional flags like --routing to handle navigation and --style define to enforce stricter type checking.

Once you have created your starter application, you can run it by using the "ng serve" command in a terminal tab. The cli prompts you for any additional information needed for analytics answer them if necessary. The ng serve command creates a server that serves your source files in the browser. It also automatically reloads your application when changes are made to the codebase.

Now that your application is running, you can begin making changes and testing them out. You can stop serving the application at any time by running the "ctrl + c" command or by typing "ng serve -s". This tutorial describes only a small portion of what can be accomplished with Angular CLI commands. By familiarizing yourself with these tools and commands, you will be able to streamline your development process and get your AngularJS applications ready for use in no time!

Angular vs. AngularJS: Which one is right for you?

If you’re looking to start building web applications, then AngularJS and Angular are two frameworks that you might consider. Google designed both frameworks but they differ significantly in their features and functions.

AngularJS is an older framework, whereas Angular is a ground-up rewrite of the previous version. The primary architectural characteristic of Angular is elements, which are the building blocks of any application. Angular also has a cleaner expression syntax focusing on property binding and event binding.

On the other hand, AngularJS provides all the core functionality required to build web applications without much configuration or setup. It recommends using static typing including generics and type annotations for better code organization. In addition, dynamic loading and asynchronous template compilations are provided through iterative callbacks. Both frameworks have their strengths and weaknesses, so it's important to evaluate which one suits your requirements before running angular applications.

1. Naming[edit]

Naming is always an important factor when it comes to software development. AngularJS, being a popular framework, has had its fair share of naming issues. For instance, when the team announced the release of a new version, it caused confusion as they called it Angular 2 instead of simply upgrading the 1x versions.

This led to many debates and discussions within the community about how to differentiate between the two versions. Ultimately, the team settled on referring to them with separate names - with AngularJS referring to versions 1.x and Angular JS referring to versions 2 and above. This naming convention has now become widely accepted and makes it easier for developers to refer to specific versions of the framework.

2. Version 2[edit]

AngularJS is one of the most popular front-end JavaScript frameworks used in web development. In April 30, 2015, Angular developers announced that they were working on a new version called "Angular 2." This version created considerable controversy because it was a complete rewrite of the original framework and had many breaking changes.

The developer preview of Angular 2 moved from alpha to beta in December 2015, and then to release candidate in May 2016. Finally, on September 14, 2016, Angular 2 was released as the final version. With Angular 2 came many improvements such as better performance, easier debugging and testing capabilities. Many developers who had initially opposed the rewrite ended up loving it because of its simplicity and ease of use. Overall, Angular 2 has proven to be an excellent upgrade to AngularJS with its robust features and improved functionality.

3. Version 4[edit]

Version 4 of AngularJS was announced on 13 December 2016, skipping version 3 due to confusion. The final version was released on 23 March 2017 and is backward compatible with Angular 2. This means that it can be used as a drop-in replacement for version 2 or easily upgraded from an existing set up.

One major improvement in Angular version 4 is the introducing of HttpClient, a smaller and easier to use library for making HTTP requests. Another addition is the ability to conditionally disable animations using router life cycle events such as guardsCheckStart, guardsCheckEnd, resolveStart, resolveEnd, and join. These powerful life cycle events allow developers to better control the behavior of their applications.
