ionic generator是命令行的功能，ionic2自动帮我们创建应用程序，从而节省了大量的时间，并增加我们的速度来开发一个项目的关键部分。
一、创建页面：ionic g page [PageName]
ionic g page login # Results: √ Create app/pages/login/login.html √ Create app/pages/login/login.scss √ Create app/pages/login/login.ts
login.ts：
import {Component} from ‘@angular/core‘;
import {NavController} from ‘ionic-angular‘;
@Component({
templateUrl: ‘build/pages/login/login.html‘,
})
export class LoginPage {
constructor(public nav: NavController) {}
}
login.html：
<ion-header>
<ion-navbar>
<ion-title>
login
</ion-title>
</ion-navbar>
</ion-header>
<ion-content padding class="login">
</ion-content>
二、创建组件：ionic g component [ComponentName]
ionic g component myComponent # Results: √ Create app/components/my-component/my-component.html √ Create app/components/my-component/my-component.ts
my-component.ts:
import {Component} from ‘@angular/core‘;
@Component({
selector: ‘my-component‘,
templateUrl: ‘build/components/my-component/my-component.html‘
})
export class MyComponent {
text: string = "";
constructor() {
this.text = ‘Hello World‘;
}
}
ionic g directive myDirective # Results: √ Create app/components/my-directive/my-directive.ts
my-directive.ts:
import {Directive} from ‘@angular/core‘;
@Directive({
selector: ‘[my-directive]‘ // Attribute selector
})
export class MyDirective {
constructor() {
console.log(‘Hello World‘);
}
}
四、创建服务提供者：ionic g provider [ProviderName]
ionic g provider userService # Results: √ Create app/providers/user-service/user-service.ts
服务代码如下：
user-service.ts:
import {Injectable} from ‘@angular/core‘;
import {Http} from ‘@angular/http‘;
import ‘rxjs/add/operator/map‘;
@Injectable()
export class UserService {
data: any = null;
constructor(public http: Http) { }
load() { if (this.data) {
}
return new Promise(resolve => {
this.http.get(‘path/to/data.json‘)
.map(res => res.json())
.subscribe(data => {
this.data = data;
resolve(this.data);
});
});
}
}
五、创建管道pipe：ionic g pipe [PipeName]
ionic g pipe myPipe # Results: √ Create app/pipes/myPipe.ts
我们的管道的代码如下
myPipe.ts:
import {Injectable, Pipe} from ‘@angular/core‘;
@Pipe({
name: ‘my-pipe‘
})
@Injectable()
export class MyPipe {
transform(value: string, args: any[]) {
value = value + ‘‘; // make sure it‘s a string
return value.toLowerCase();
}
}
最后，我们生成的应用程序结构如下图：
