Angular is a platform and framework for building single-page client applications using HTML and TypeScript. The basic building blocks of Angular include components, modules, directives, decorators, pipes, data binding, templates, and services. Components define views with templates and logic. Modules organize related code. Directives modify DOM elements. Decorators add metadata. Pipes transform data. Data binding syncs data and UI. Templates define views. Services provide reusable functionality.
The Lifecycle Hooks makes every complex state management easier and simpler, so let's explore the Lifecycle Hooks of Angular to fine-tune the behavior of our components.
This document discusses data binding in Angular, including the differences between HTML attributes and DOM properties, the three types of data binding (one way and two way), and examples of each type of binding. It explains that one way binding can update properties, classes, styles, attributes and listen to events, but not read values. Two way binding uses the NgModel directive to both display and update a data property when the view changes. The document provides examples of property, event, class, style and attribute binding and how Angular matches bindings to component properties and events.
The document summarizes Angular directives including ngIf, ngFor, ngSwitchCase, ngClass, and ngStyle. It describes how ngIf and ngFor are structural directives that change the DOM layout by adding and removing elements. NgIf and ngFor use an asterisk syntax that gets desugared into <ng-template> elements. NgFor iterates over collections and supports additional syntax like trackBy. NgSwitch is a set of cooperating directives that displays different elements based on a switch expression. NgClass and ngStyle are attribute directives that update CSS classes and styles on elements.
This document provides an overview and explanation of React Hooks. It introduces common Hooks like useState, useEffect, useReducer, and custom hooks. useState is used to add local state to functional components. useEffect is similar to component lifecycle methods and lets you perform side effects. useReducer is an alternative to useState for managing state in a single object. Custom hooks let you extract reusable logic and share it without changing components. The document also includes a FAQ addressing questions about hooks and class components.
This document outlines an AngularJS certification training agenda that covers directives. It defines directives as classes that extend HTML and transform the DOM. There are three types of directives: components, structural directives, and attribute directives. Built-in directives like NgFor and NgIf are covered, which add and remove elements. The document demonstrates how to create a custom attribute directive by using the @Directive decorator and accessing native DOM elements.
This document provides an overview of Angular's template-driven and model-driven forms. It describes the key directives, classes, and interfaces used for building forms in Angular. It explains how to add validation, track form state, create custom validators, and tie forms to components and templates. The document also demonstrates how to set up two-way data binding between forms and models using directives like ngModel, ngFormControl, and ngForm.
This document discusses React hooks and how they enhance functional components. It explains that hooks allow functional components to maintain state and lifecycle methods like class components. The key hooks discussed are useState for managing state, useEffect for side effects like data fetching, and useCallback and useMemo for optimization. Custom hooks are also covered as a way to extract reusable logic. Overall, hooks improve on class components by making code more modular, reusable and easier to test.
A directive is a custom HTML element that is used to extend the power of HTML. Angular 2 has the following directives that get called as part of the BrowserModule module.
ngif
ngFor
If you view the app.module.ts file, you will see the following code and the BrowserModule module defined. By defining this module, you will have access to the 2 directives.
This document discusses Angular components, dependency injection, and routing. It defines Angular as being built on modules, components, templates, and services. Components are the basic building blocks and make up a hierarchical tree structure. Dependency injection allows components to access services. Routing in Angular uses a router to navigate between views and components based on URL changes.

The session will provide the knowledge about react page life cycle and how more precise actions or operations can be performed using react hooks concepts
- Angular modules help organize an application into blocks of related functionality. Modules declare components, directives, pipes and services that belong to that module.
- There are different types of modules like root modules, feature modules, and shared modules. The root module launches the app. Feature modules extend functionality. Shared modules contain reusable constructs.
- Modules can import and export specific constructs to make them available to other modules. Services declared in a module are singletons app-wide unless the module is lazy loaded. Core modules contain global services imported by the root module only.
Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript. It is an update to AngularJS with a focus on mobile and typesafety. Major versions include Angular 1.x, 2.x, 4.x and 5.x. Angular uses components, services and modules to build applications with templates and styles. It is compiled to JavaScript using transpilation and supports AOT and JIT compilation. Common tools used with Angular include the Angular CLI, Webpack and Zone.js.
Angular Kickstart document provides an overview of Angular including:
- Angular is a client side JavaScript framework that allows building of single page applications.
- A single page application loads initial content via the first page load and subsequent content without reloading the page.
- The document discusses Angular features such as modularity, performance, TypeScript support, and building blocks like modules, components and directives. It also provides instructions on setting up the development environment for Angular applications.
Debugging in JavaScript
It is common to have errors while writing codes and the errors can be due to syntax or logical. These errors create a lot of ambiguity in the logic and understanding of both users and programmers. There can also be errors in the code which can remain invisible to the programmer’s eye and can create havoc. To identify these errors we need Debuggers that can go through the entire code or program, identify the errors and also fix them.
-Debugger
The debugger keyword is used in the code to force stop the execution of the code at a breaking point and calls the debugging function. The debugger function is executed if any debugging is needed at all else no action is performed.
Angular is a JavaScript framework for building client-side web applications. It was created and is maintained by Google. Some key points:
- Angular uses components to build modular applications
- It utilizes TypeScript for type safety and features like classes and interfaces
- The framework emphasizes dependency injection, data binding, and directives
The document provides an introduction to building a simple web server in Node.js. It discusses organizing the code into modules, including a server module to start the web server, a routes module to route requests, and a request handlers module. It also covers basic concepts like using the http module to create a server, handling requests, and returning responses. The server currently returns the same "Hello World" response for all requests, and next steps involve routing requests to proper handlers to return the appropriate content based on the URL.
This document discusses different types of data binding in Angular, including interpolation, property binding, event binding, and two-way binding. Interpolation is used to display data in templates. Property binding passes data from the component to an element property. Event binding handles user interactions by passing events from the template to event handler methods. Two-way binding uses ngModel to establish bidirectional data flow between a component and view. The document also provides examples of parent to child component communication using input binding to pass data from parent to child components.
Angular IO Overview
The presenter introduces foundational Angular IO concepts like components, TypeScript, and the Angular CLI tool. Angular IO is a component-based framework for building single page applications. It uses TypeScript for strong typing. Components couple custom HTML elements to functionality. The Angular CLI helps generate and build Angular applications.

The document discusses Angular routing and provides an example implementation. It first generates components for home, about, userList and user pages. It then sets up routes in app.module.ts to link URLs like /home and /about to their corresponding components. Navigation links using routerLink are added. To handle empty/invalid URLs, a default route is set to redirect to /home. Sub-routes are created under /user linking /user/list to UserListComponent, which displays a list of users. Clicking a user name creates a child route passing the name as a parameter to the UserComponent to display that user's details page.

Angular App Bootstrapping
main.ts AppModule AppComponent
❖ Main typescript file from where
the execution begins
❖ Initializes the platform browser
where the app will run and
bootstrap AppModule
❖ Root Module of Angular App
❖ Bootstrap AppComponent and
inserts it into the index.html
host web page
❖ Root Component under which
other components are nested
❖ First Component to inserted in
the DOM.
27. Software IndustrySultan Ahmed Sagor
Why Angular App is bootstrapped
❖ Allow us to write Angular App that can be hosted on other environments
❖ Import the platform based Applications
❖ For example,
❖ @angular/platform-browser-dynamic is used for running the app on
browser.
Angular is not only a framework for creating WEB-only Applications
29. Software IndustrySultan Ahmed Sagor
Tour Of Heroes
❖ By the end of this tutorial, we will create the following web page using Angular components.
30. Software IndustrySultan Ahmed Sagor
Tour Of Heroes
❖ You can click the two links above the dashboard
("Dashboard" and "Heroes") to navigate between this
Dashboard view and a Heroes view.
❖ If you click the dashboard hero "Magneta," the router o
pens a "Hero Details“ view where you can change the hero's name.
31. Software IndustrySultan Ahmed Sagor
Tour Of Heroes
Clicking the "Back" button returns you to the Dashboard. Links at the top
take you to either of the main views. If you click "Heroes," the app
displays the "Heroes" master list view.
32. Software IndustrySultan Ahmed Sagor
Tour Of Heroes
❖ When you click a different hero name, the read-
only mini detail beneath the list reflects the new
choice.
❖ You can click the "View Details" button to drill into
the editable details of the selected hero.
34. Software IndustrySultan Ahmed Sagor
Tour Of Heroes
❖ Let us create a Hero component.
❖ Command of creating hero component:
❖ ng generate component heroes
❖ As a result, the following classes/html file will be created:
❖ heroes.component.ts
❖
36. Software IndustrySultan Ahmed Sagor
Create a Hero class
❖ Let us create a Hero class to hold all the information that hero can contain
❖ Path: src/app/hero.ts
export class Hero {
id: number;
name: string;
}
37. Software IndustrySultan Ahmed Sagor
Show the Hero Object
❖ Let us create a Hero class to hold all the information that hero can contain
<h2>{{hero.name}} Details</h2>
<div><span>id: </span>{{hero.id}}</div>
<div><span>name: </span>{{hero.name}}</div>
38. Software IndustrySultan Ahmed Sagor
Format with UpperCasePipe
❖ Let us create a Hero class to hold all the information that hero can contain
<h2>{{hero.name | uppercase}} Details</h2>
39. Software IndustrySultan Ahmed Sagor
Edit The hero
❖ Users should be able to edit the hero name in an <input> textbox.
❖ The textbox should both display the hero's name property and update that property as the user types.
❖ That means data flows from the component class out to the screen and from the screen back to the class.
❖ To automate that data flow, setup a two-way data binding between the <input> form element and the
hero.name property.
41. Software IndustrySultan Ahmed Sagor
The missing FormsModule
❖ Notice that the app stopped working when you added [(ngModel)].
❖ To see the error, open the browser development tools and look in the console for a message like
42. Software IndustrySultan Ahmed Sagor
AppModule
❖ Angular needs to know how the pieces of your application fit together and what other files and libraries the
app requires. This information is called metadata.
❖ Some of the metadata is in the @Component decorators that you added to your component classes. Other
critical metadata is in @NgModule decorators.
❖ The most important @NgModule decorator annotates the top-level AppModule class.
❖ The Angular CLI generated an AppModule class in src/app/app.module.ts when it created the project. This is
where you opt-in to the FormsModule.
43. Software IndustrySultan Ahmed Sagor
Import FormsModule
❖ Open AppModule (app.module.ts) and import the FormsModule symbol from the @angular/forms library.
import { FormsModule } from '@angular/forms'; // <-- NgModel lives here
❖ Thenn add FormsModule to the @NgModule metadata's imports array, which contains a list of external modules that the app
needs.
imports: [
BrowserModule,
FormsModule
],
44. Software IndustrySultan Ahmed Sagor
Declare the HeroesComponent
❖ Every component must be declared in exactly one NgModule.
❖ You didn't declare the HeroesComponent. So why did the application work?
❖ It worked because the Angular CLI declared HeroesComponent in the AppModule when it generated that component
❖ Open src/app/app.module.ts and find HeroesComponent imported near the top.
45. Software IndustrySultan Ahmed Sagor
Declare the HeroesComponent
import { HeroesComponent } from './heroes/heroes.component';
❖ The HeroesComponent is declared in the @NgModule.declarations array.
declarations: [
AppComponent,
HeroesComponent
],
