![]() Run the following command: npm install -g Once this command has finished running without any errors, we can make sure that the ng command works as expected by running the following command: ng -version This will give us access to the ng command:Ģ. In this exercise, we will use npm to globally install Angular CLI. It's all abstracted away and available through one handy command: ng.įor more information about Angular CLI, refer to the project page on GitHub at. ![]() One of the main benefits of using Angular CLI is that you don't need to configure any build tools. Easily install and add third-party software (using ng add, since version 6).Generate code using the best practices from the Angular team.Run the application in development mode.It's an open source project that is maintained by the Angular team and is the recommended way to develop Angular applications.Īngular CLI offers the following functionalities: Installing Angular CLIĪngular CLI is the officially supported tool for creating and developing Angular applications. Structure that is shown in this application. It should be easy for any Angular developer to extend on the logic and Although the app is simple, we will develop it using best practices for Angular development. From the list of posts, we can click a link that brings us to the post detail page. The Angular application we will build is going to be a list of posts that you regularly see on a social networking site such as Twitter. Users will see a blank page until the whole application is downloaded, and maybe they will just use a small part of it. ![]() This is also the case when sharing links to the sites on social media, since these are generally static instead of dynamic.Īnother weakness is that the initial download is bigger, and this can be an issue on, for instance, mobile devices with slow connections. WeaknessesĬlient-side rendered websites are difficult for a search engine to index, as they need to execute the JavaScript to display how the page looks. This takes load off the server, and this results in better scalability. The server can be mostly stateless as the page is not rendered there it just serves the HTML, JavaScript, and stylesheets one time and is done. Parts of the page can be reloaded or updated without having to refresh the whole browser. This uses less bandwidth and it generally gives the user the feeling that the website or application is very fast. ![]() The benefit of client-side rendering is that the pages are highly interactive. There is often a single page that is downloaded, with a JavaScript file that builds up the actual page (hence the term single-page application). When we talk about client-side rendering, we generally refer to an application or website that uses JavaScript running in the browser to display (render) the pages. This results in more bandwidth and gives the user the feeling that the page is loading slower than it actually is. The downside of server-side rendering is that the pages often have only basic possibilities of interaction with the user, and when the content changes, or the user navigates to another page, they have to re-download the whole page. The content is ready to be consumed, and the client (in this case, the search engine) does not need to run any code to analyze the page. It works great with indexing by search engines and with sharing on social media. The benefits of server-side rendering is that the generation happens on a server, making it ready to consume in the browser once it's downloaded. On this server, web pages are created (rendered) and the output of that rendering (the HTML) is sent to the browser, where it can be displayed directly. When we talk about the server-side rendering of websites, we generally refer to an application or website that uses a programming language that runs on a server.
