You either continue reading from the Angular 4 related content or just jump directly to Angular 5 section. 4
Angular 4 Features Angular 4 is available and comes with many improvements and new features such as: 4
Size and performance: Angular 4 applications are smaller by hundreds of kilobytes, thanks to the improvements to the View Engine which have reduced the size of generated components code by around 60% . The Animations are no longer part of Angular core which means that the apps which don't use them don't need to include the extra code in their final bundles. You can use animations in your apps by using BrowserAnimationsModule which can be imported from @angular/platformbrowser/animations. Improved *ngIf and *ngFor: *ngIf now supports the else syntax, for example it's easy now to write templates in this way
Hello Angular 4
Still loading
If the ready variable is false Angular will show the loading template. You can also assign and use local variables inside both *ngIf and *ngFor expressions, for example: { { el } }
The adoption of Angular universal as part of Angular: the Angular team has adopted Angular Universal which is a community driven project that allows developers to use server side rendering for Angular apps. It's available from @angular/platform-server. You can find more information on:Angular 4.0.0 now available official Angular blog post and Angular 4.1.0 now available official Angular blog post
Getting Started with Angular 4 / Angular 5 If you want to get started developing Angular 4/5 web applications, you have multiple options: Install Angular by hand, Install and use Angular CLI, Upgrade from an existing Angular 2+ project. Before you can install Angular you need to have Node.js and NPM installed on your development machine. So go ahead and open your terminal and type the following node -v
If you get the version of an installed Node.js then you already have the platform installed. If the command is unknown by your terminal then you need to install Node.js. Installing Node.js is easy and straightforward, you just need to visit their official website then grab the installer for your operating system and follow the instructions. Now if you open your terminal under Linux/MAC or command prompt under Windows and execute node -v
You should get an output displaying your Node.js installed version
Updating to Angular 4 from Angular 2 If you have already an Angular 2 project and want to update it to Angular 4, you can do that by simply installing a few npm packages.
Windows Just copy and paste the following command in your prompt
npm install @angular/common@latest @angular/compiler@latest @angular/compiler-cli@latest @angular/core@latest @angular/forms@latest @angular/http@latest @angular/platf
Linux and MAC Copy and execute this on your terminal npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router,animations
Installing the Angular CLI The Angular CLI is a handy command line utility built by the Angular team to easily and quickly generate new Angular applications and serve them locally. It can also be used to generate different Angular constructs such as components, services and pipes etc. Before you can use the Angular CLI, you need to install it via npm, so go ahead and open your terminal or your command prompt then simply enter: npm install -g @angular/cli
To check the version of your installed Angular CLI, type: ng -v
You can also run ng -v from inside an Angular project to get the version of Angular
Generating an Angular 4 / Angular 5 Project Using the Angular CLI Using the Angular CLI, you can generate an Angular 4+ project with a few commands, the CLI will take care of generating the project files and install all the required dependencies. Open your terminal or your command prompt then run: ng new angular4-project
After finishing the installation enter: cd angular4-project ng serve
Your project will be served locally from http://localhost:4200.
Generating an Angular 4 from GitHub Repository You can also clone a quick-start Angular project from GitHub to generate a new Angular 4 project. So make sure you have Git installed then run the following: git clone https://github.com/angular/quickstart my-proj cd my-proj npm install npm start

Angular 5 Features Angular 5, code named pentagonal-donut, was just released. It has new features and internal changes which make Angular applications faster and smaller. In this section we will go over the most important changes and instructions on how to upgrade your existing Angular 2+ project to latest version. As of Angular 5.0.0, the build optimizer is enabled by default which applies a series of optimizations to builds. The Angular team has also improved the compiler which can make now faster rebuilds (especially for production and AOT builds) thanks to incremental compilation. The Angular team has added many features to Angular decorators. Developers can now ship faster and smaller bundles by removing white spaces. The Angular compiler now supports TypeScript 2.3 Transforms a new feature that enables you to hook into the standard TypeScript compilation pipeline. Make sure to use the --aot switch to enable this feature. ng serve --aot
You can now get rid of white spaces in template's code by setting preserveWhitespaces to false in the component's decorator. You can also turn it on globally by setting "preserveWhitespaces":false
underangularCompilerOptions in tsconfig.json . This will help reduce your
app's final bundle size. You can now use lambdas inside Angular componet's decorator. New improved number, date, and currency pipes that have better standardization support across browsers without i18n polyfills. The old HTTP module is now deprecated in favor of HttpClient which was introduced in Angular 4.3
Changes before Upgrading If you have an existing Angular 2 or Angular 4 project, you need to make sure you apply some changes to your project's source code before you can upgrade to Angular 5. This is the list of changes that need to be done. https://angular-update-guide.firebaseapp.com/ First of all, upgrade essential Angular packages to latest version 5.0.0. $ npm install @angular/{animations,common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router
Upgrade to TypeScript 2.4.2 and RxJS 5.5.2. RxJS v5.5.2 is the default reactive library for Angular 5. Change to in your project's code. Upgrade HTTP API to HttpClient API since HTTP module is deprecated in Angular 5. If your project is making use of the Flex Layout module, you need to upgrade to its latest release which is compatible with Angular 5 (OpaqueToken was removed in Angular 5).
Getting Started with Angular 5 from Scratch Fortunately for you, if you already have a previous working experience with Angular 2 or Angular 4, starting a new Angular 5 project is very much the same process. In case you don't have any previous experience with Angular framework just follow the instructions below to install Angular 5 from scratch.
Prerequisites Before you can install Angular 5, you need to have some prerequisites. You need to have Node.js installed. You need to have NPM (Node Package Manager) installed. Don't worry both requirements can be installed by going to the official website and download the installer for your operating system. Next install the latest CLI from npm by running the following command from your terminal: npm install @angular/cli -g
Once the Angular CLI v1.5.0 is installed on your system. You can create Angular 5 applications using the ng command. You can check for the installed version of the Angular CLI using: $ ng -v
You should get an output like: Angular CLI: 1.5.0 Node: 6.11.4 OS: linux ia32 Angular: ...
You can create your first Angular 5 project using one command: $ ng new a-new-project --style=scss --routing
You can notice the two flags at the end, --style=scss which instructs the Angular CLI to use SCSS for styling and --routing for adding basic routing support to the new Angular project. Once the project is scaffolded, you can navigate inside your project then serve it. $ cd a-new-project $ ng serve
That's it, you now have a new Angular 5 project ready for you to build your next awesome Angular application. Just like Angular 4, you can also use the quick start project from Github to generate Angular 5 projects. git clone https://github.com/angular/quickstart angular5project cd angular5project npm install npm start
Conclusion Thanks to Angular CLI v1.5.0 you can get started with Angular 5 by generating a new project quickly with a variety of flags to customize and control the generation process. Now that we have created a new project, in the next tutorial, we're going to start learning about the fundamentals of Angular 5 starting with components. On the previous section we have seen different ways to create a new Angular 4 project or updating an existing Angular 2+ project to use Angular 4.
