Angular is a platform that makes it easy to build applications with the web. Angular combines declarative templates, dependency injection, end to end tooling, and integrated best practices to solve development challenges. Angular empowers developers to build applications that live on the web, mobile, or the desktop.
TEMPLATE WITH SINGLE LINE CAN BE USED SINGLE OR DOUBLE QUOTES import { Component } from '@angular/core' ; @ Component ({ selector: 'app-root' , template: "hi {{title}}" }) export class AppComponent { title : string = 'angular' ; } TEMPLATE MORE THAN 1 LINE USED BACKTICKS import { Component } from '@angular/core' ; @ Component ({ selector: 'app-root' , template: `hi {{title}} ABC XYZ` }) export class AppComponent { title : string = 'angular' ; } USING TEMPLATEURL import { Component } from '@angular/core' ; @ Component ({ selector: 'app-root' , templateUrl: './app.component.html' }) export class AppComponent { title : string = 'angular' ; }
What is force re-rendering? Force re-rendering in React is like pressing the refresh button on a webpage, even when the page seems just fine. In React, it means telling a component to update and redraw itself, even if nothing has really changed in the data (stat/props) it uses. Although React is usually good at knowing when it is time to update a component, there are moments when you want to take the reins and tell it to refresh a certain part of the codebase. In this article, we will explore this in more detail. Understanding React’s rendering behavior Let’s take a closer look at how React’s rendering process works by default. To understand when and why you might need to nudge React into re-rendering, you need to get familiar with its underlying architecture. At the heart of React’s rendering magic lies the Virtual DOM. Imagine it as a clone of the actual DOM, the structure of your webpage. React uses this Virtual DOM to figure out what needs to be updated when your data ch...
Disclaimer Let’s get this over with as quickly as possible. I need to mention two things. First, some of the information in this book may be incorrect (I’m a human being that makes mistakes). Also, this book is somewhat opinionated. I have tried my best to be as technically accurate as possible, but I’m still learning a lot and have much yet to learn about Angular 4. I do have some strong opinions, but please don’t take them as gospel. I don’t intend to harm anything or anyone—I’m not smart enough for that. Scope This scope of this book is to help developers get started in Angular 4. You’re not going to read and learn all there is to know about Angular54. That’s not the purpose of this book; getting up to speed as a developer is. In my opinion, getting up to speed means having a good overall knowledge—sufficient to start working. Approach This book contains chapters with small code examples built with the Angular CLI. You’ll be able to try out code without being burden...
