Angular has become the most prominent and widely used javascript framework nowadays. This is because of its ability to build websites with a seamless user interface and experience. Whenever it comes to front-end development there is always a consistent requirement for diverse Angular web development skills.
To become a professional Angular developer, one needs to be good enough not only in the Angular framework but also in a wide range of UI tech stacks. Just learning more technologies won’t make you a better professional, A professional is one who has the knowledge to Identify and use the right tool at the right place.
So if you are a newbie to Angular, here are 8 important skills that you must look into for becoming a professional Angular developer.
Node Package Manager (NPM)
Node Package Manager is one of the first command line tools that you will come across when you do Angular web development. NPM packages various libraries and installs their dependencies to the application that we can make use of to develop the web pages. The NPM uses the package.json file to keep track of the libraries installed.
Angular CLI
This is one of the common command line tools that we will be using in our daily Angular development. The Angular command line interface gives the user the simplified command to initialize, develop, scaffold, and maintain angular applications. The main advantage of using the angular CLI is that it reduces our work of creating the files, adding a proper extension, writing its dependencies, etc. These are automatically handled when CLI is used.
HTML and CSS
HTML and CSS are the important tools that you should know once you are into web development. Angular is just a framework, without writing the proper HTML and proper CSS styling it is of no use to the end user. HTML is a markup language that is used by the web browser to display the contents to the user. Nowadays cross-browser and cross-device web development has gained prominence. So in this world, if the web page is not presented properly then it will be a failure. This is where the CSS comes into play to add styles to the HTML tags and make them compatible with a wide range of devices.
Javascript
Angular is nothing but a Javascript framework, which means a developer who is an expert in angular will also be an expert in JS. JS is a powerful scripting tool that is useful by the browser to manage client-side web-behavior. No matter what code we develop using angular, in the end, it is converted to JS while the application is run on the browser. Learning JS is the only way you can write high-performance web applications. JS provides a huge list of data structures, loops, and functions that make our web development much easier and more scalable.
Typescript
Typescript lets you write javascript more simply and efficiently. It is the superset of javascript. From Angular version 2 onwards it enables you to use Typescript for coding in Angular. But the typescript is not recognized by the browsers so the transpilation is always carried out at the end of the development to convert the TS files to plain js. Typescript gives you more advantages over JS like static typing and defining interfaces which give you the benefit of using types. It helps you to make use of ES6 and ES7 features, great tooling support for IntelliSense, etc. Typescript knowledge becomes an inevitable aspect when coming to Angular web development nowadays.
RxJS
Whenever you are developing an Angular application there will be some scenarios where you may want to handle some asynchronous events; this is where the RxJS comes into play. RxJs is a JS library is useful for reactive programming. It provides a variety of operators and methods to handle asynchronous events. RxJs is often very difficult to understand and use all the RxJs library tools due to its multitude of concepts, large API surface, and fundamental shift in mindset from an imperative to declarative style. However, the basic RxJs concepts like observables, pipes, etc. can be useful in your daily application development, and refer to the documentation more to dive deeper.
Responsive Design
Cross-browser compatibility and cross-device compatibility have now become inevitable skills when it comes to web development. Responsive web design is an approach to designing and developing web applications that are compatible with all the major browsers and screen ratios. The web designer has to define some media queries to identify the size of the devices and make the web page adjust accordingly. Using direct media queries to create responsive design has become an older fashion now. Now libraries like bootstrap help us by giving direct APIs that will adjust on their own for different screen ratios.
Testing and Debugging
Testing and debugging are important parts of the software development process. An Angular developer should possess these skills to become a good professional. Angular provides testing frameworks like Jasmine, Jest, etc. to write various unit test cases and verify the code works well for a wide range of inputs. The test-driven development makes sure that the new modules added to the project or modification of the existing logic will not break the business logic defined. Debugging is important to find the erroneous code and rectify it. From a user point of view, a user always expects a bug-free application that gives him all the required features. For this to happen, the application has to be debugged to the maximum extent and eliminate all possible bugs. Google chrome’s developer tools are excellent debugging tools that the developers can make use of to catch and rectify errors.
