Detailed explanation of using Router in Angular 5.x
This time I will bring you a detailed explanation of the use of Router in Angular 5.x. What are the precautions when using Router in Angular 5.x. The following is a practical case, let's take a look.
Preface:
Jumping between Angular APP views depends on Router (routing). In this chapter, we will talk about the application of Router
The running results are as follows. Three navigation bars are set up, Home, About, and Dashboard. Click on different navigation bars to jump to the corresponding page:
Create 3 components
-
ng g c home
ng g c about
- ##ng g c dashboard
Routing and configuration
(1)**Introduce Angular Router **When using Angular Router, you need to introduce RouterModule, as follows:
// app.module.ts import { RouterModule } from '@angular/router'; imports: [ BrowserModule, RouterModule ],(2) Routing configurationRemember who manages the component? Yes, it is managed by the module. Therefore, introduce the newly created component into app.moudle. As follows:
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { RouterModule } from '@angular/router'; import { appRoutes } from './routerConfig'; import { AppComponent } from './app.component'; import { AboutComponent } from './components/about/about.component'; import { HomeComponent } from './components/home/home.component'; import { DashboardComponent } from './components/dashboard/dashboard.component';Tips: Pay attention to the path of the component. For ease of management, we moved the newly created component to the components folder.
Create the Router Configure file
In the app directory, create the routerConfig.ts file. The code is as follows:import { Routes } from '@angular/router'; import { HomeComponent } from './components/home/home.component'; import { AboutComponent } from './components/about/about.component'; import { DashboardComponent } from './components/dashboard/dashboard.component'; export const appRoutes: Routes = [ { path: 'home', component: HomeComponent }, { path: 'about', component: AboutComponent }, { path: 'dashboard', component: DashboardComponent } ];Description: Angular 2.X and above, start using TypeScript to write code instead of
JavaScript, so the suffix of the file is: ts instead of js
How to call this routerConfigue file? It needs to be loaded into app.module.ts because app.moudle.ts is the entrance to the entire Angular App.// app.module.ts import { appRoutes } from './routerConfig'; imports: [ BrowserModule, RouterModule.forRoot(appRoutes) ],
Declare Router Outlet
In the app.component.html file, add the code:<p> </p><h1> {{title}}!! </h1> <nav> <a>Home</a> <a>About</a> <a>Dashboard</a> </nav> <router-outlet></router-outlet>
Run
Enter the path where the project is located and run;ng serve --openWhen webpack is compiled successfully, in the browser address bar, enter: http://localhost:4200That is You can see the results at the beginning of this article.
Regarding Router, change the way of writing:
In the app.moudle.ts file, the code is as follows:imports: [ BrowserModule, RouterModule.forRoot( [ { path: 'home', component: HomeComponent }, { path: 'about', component: AboutComponent }, { path: 'dashboard', component: DashboardComponent } ] ) ],In this way, you can There is no need to create a separate routerConfigure.ts file.
Summary
Since the introduction of component-oriented (component), routing management is much more convenient thanAngularJS (1.X).
Further optimization:Perhaps you have noticed that when accessing http://localhost:4200, its path should be "/", and we should set this default path.{ path: '', redirectTo:'/home', pathMatch: 'full' },I believe you have mastered the method after reading the case in this article.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.
