前端框架完全不懂。
看着angular中文官网的英雄编辑器教程和核心知识,用偷懒的类比法,从flask django的角度 记录一下自己对angular的理解.
这个文件有点类似extends.py 在这里import各种依赖的插件。比如要双向绑定,就要import FormsModule
import { NgModule } from ‘@angular/core‘; import { BrowserModule } from ‘@angular/platform-browser‘; import { FormsModule } from ‘@angular/forms‘; // <-- NgModel lives here import { AppComponent } from ‘./app.component‘; @NgModule({ imports: [ BrowserModule, FormsModule // <-- import the FormsModule before binding with [(ngModel)] ],
import { NgModule } from ‘@angular/core‘; import { BrowserModule } from ‘@angular/platform-browser‘; import { FormsModule } from ‘@angular/forms‘; import { AppComponent } from ‘./app.component‘; import { DashboardComponent } from ‘./dashboard.component‘; import { HeroDetailComponent } from ‘./hero-detail.component‘; import { HeroesComponent } from ‘./heroes.component‘; import { HeroService } from ‘./hero.service‘; import { AppRoutingModule } from ‘./app-routing.module‘; @NgModule({ imports: [ BrowserModule, FormsModule, AppRoutingModule ], declarations: [ AppComponent, DashboardComponent, HeroDetailComponent, HeroesComponent ], providers: [ HeroService ], bootstrap: [ AppComponent ] }) export class AppModule { }
类似
from flask import Flask from scenario import scenario from situation import situation from posture import posture from assistant import assistant from do_action import do_action from rule import rule # ————————注册blueprint———————— app.register_blueprint(scenario) app.register_blueprint(situation) app.register_blueprint(posture) app.register_blueprint(do_action) app.register_blueprint(assistant) app.register_blueprint(rule) app = Flask(__name__)
import { Component } from ‘@angular/core‘; @Component({ selector: ‘my-app‘, template: ` <h1>{{title}}</h1> <nav> <a routerLink="/dashboard" routerLinkActive="active">Dashboard</a> <a routerLink="/heroes" routerLinkActive="active">Heroes</a> </nav> <router-outlet></router-outlet> `, styleUrls: [‘./app.component.css‘], }) export class AppComponent { title = ‘Tour of Heroes‘; }
@Component 相当于 flask里
1 /templates/每个blueprint下的用 jinja2 语法的XXX.html,
2 /static/下的 css
区别在于:flask强调"动静分离"。这样部署的时候,static的东西用nginx, web api部分 用 gunicorn
angular 的component(有点类似Unity3d里的gameobject),把css 模板 都封装在了组件里,写在了代码里。
angular的“前后端”统统用ts/js搞了。这样开发者不需要太在乎“动静”与“前后"的分野。
Model部分
export class Hero {
id: number;
name: string;
}
类似 models.py定义的ORM类。可以送进模板用双括号访问属性 {{hero.name}}
ng的双向绑定很给力。
<div> <label>name: </label> <input [(ngModel)]="hero.name" placeholder="name"> </div>
