Angular 4 tutorial pdf free download

PDFs include text, images, embedded fonts, hyperlinks, video, interactive buttons, forms, and more. To handle the UI part, we should install the Bootstrap library in Angular. The PDF. Well, this is it. We have learned how to export data in Angular with jsPDF package. The rationale is that we need to get data from each customer to generate a table row in a table from Part This is the part when things start coming together: we use directive ngFor to loop through each customer in filteredCustomers and interpolate data from a customer into a table row.

We learn a few tricks about rendering data conditionally using ngIf. Event Binding is crucial when we need to handle an event, like a mouse move or a click. In this screencast, Dan guides us through adding functionality to sort the data in our table.

We will start on it in this chapter and finish it when we get to the Services part of our course. We have some data in a people array in our customers. And bind to it in our parent component template to pass data from parent to child app-customers-list in this case :. This is really the way we have our data, so we could just go and update it directly, or we can use a built-in Angular feature called Pipes to update it for us! In this cast, Dan walks us through adding functionality to our filter-textbox.

We learn more about Angular Output and EventEmitter properties, create our filter event handler and bind it to our filter textbox:. In this chapter, we look at Angular Services. We saw services in the diagram earlier. Components should focus on presenting data and handling user events. When additional functionality needs to be performed they should delegate to services to provide for a more maintainable application and better code reuse.

From a chapter earlier we have seen an import of Injectible which is a decorator that allows for something called Dependency Injection or DI for short another powerful feature built-into Angular.

We will be adding HttpClient to a constructor of our data. We will be using Observables to deal with asynchronous code. In a nutshell, it allows us to start an operation and then subscribe to data that is returned. Once the data comes back from the server, the subscription ends and we can unsubscribe. Dan discusses the necessary code to call the server and then subscribe to the response using RxJS piping and operators.

Now that we have a way to get the data, we need to inject the service into one of our components. We can now change this. We need to bring our data. Dan handily provided a prewritten service for us, which we can use, so in this chapter, we will practice bringing in service into our components, in this case, customers-list. Dependency injection makes it extremely easy to access reusable code such as the sorter or data services. This chapter will introduce Routing, which is an essential part of modern applications.

In our case, when a user clicks on a Customer, we might want to show them Orders. Routing is one way to very neatly achieve this. Routes are used to hook a specific URL to a component and in the next few chapters, we will be focusing on the top part of our Angular diagram.

In order to use Routing in Angular in our app. First, we create a customers-routing. A good and stable framework like Angular is already tested and well understood by the others. Business application developers use frameworks, such as the Microsoft Entity Framework, to ease their pain and speed up development when building database-related applications.

I hope I have explained to you the need for a framework and, more specifically, the fact that AngularJS is a great choice. Angular 8 was officially announced in just a few days ago i. The new release version is not a complex major update. But still, this version contains many features include some opt-in features. Also, this version contains some new features and also upgradation of the previous version features.

Some of the important features which included in Angular 8 versions are — Typescript 3. LTA What is TypeScript? As all, we know that Angular 8 or earlier versions up to Angular 2. So, it is necessary to understand some basic concepts of Typescript. Typescript is basically a super-set scripting language of JavaScript. It is a strict syntactical superset of JavaScript and adds optional static typing to the language.

Typescript is totally based on the OOPs concept. Actually, Typescript is basically acted as a transpiler. Although we can develop and compile the code in Typescript. But it is actually a transpiler. Since code written in Typescript has been converted into another language like Javascript after compilation.

And then compiled Javascript-based code is run in the browser for the application. So, in a simple word, transpiler means it basically converts one language to another language. In spite of that, we can also create any class and its related functionalities or objects in Typescript.

The said project folder contains the below folder structure — The created project contains the following folders — e2e - This folder is for an end to end testing purposes. It contains the configuration files related to performing the unit test of the projects. It contains 3 subfolders as — app - App folder contains the Angular project-related files like components, HTML files, etc. About Different Config Files When we create any Angular based project using Angular CLI, then every time it will create 3 different configuration files which help us to configure the projects along with its related dependencies.

These configuration files are — tsconfig. The tsconfig. Sample of tsconfig. Also, we can provide the build definition of the project using this file. It tells the system which files need to change when we use ng build or ng serve command. This file is responsible for the bootstrapper operation of our Angular modules.

Disabling Development mode turns off assertions and other model-related checks within the framework. AppModule — This option indicates which module acts as a root module in the applications. An Angular application may contain more than one Angular module. Angular modules is a process or system to assemble multiple angular elements, like components, directives, pipes, service, etc.

In Angular, NgModule decorator is used to defining the Angular module class. Sometimes, this class is called a NgModule class.
