# 爱奥尼亚的Hello World !!
### 这是一篇社论它将通过你在Ionic制作一个简单的Hello World程序。
### 脚步
#### 1.如果没有安装,请安装`ionic` `npm` `angular`和`cordova` 。\[有关详细信息,请参阅[第一篇](https://guide.freecodecamp.org/ionic)介绍\]
```shell
sudo apt-get install nodejs
sudo apt-get install npm
sudo npm install -g ionic cordova
```
#### 2.创建名为`helloworld`的文件夹
```shell
ionic start helloworld blank
```
注意: 由于这是小项目因此在程序执行期间出现提示时输入No或N.
#### 3.将目录更改为`helloworld` \[这是您的离子目录\]
```shell
cd helloworld
```
#### 4.在文本编辑器中打开文件夹。你会看到各种文件和子文件夹。
不要惊慌这些文件由npm为你自动生成。只需转到`src` - > `page` - > `home` - > `home.html`
#### 5.基本文件格式
```
`home.html` is the html page where you can write html syntax.<br/>
`home.scss` is the css page to write css syntax.<br/>
`home.ts` is the typescript page to write typescript code.
```
#### 6.删除模板并添加html语法如图所示。
```html
<ion-header>
<ion-navbar>
<ion-title>
Ionic Project
</ion-title>
</ion-navbar>
</ion-header>
<ion-content padding>
<h2>Hello World </h2>
</ion-content>
```
#### 7. Save the code and run
```

#### 8.要查看运行的代码请转到浏览器并在URL中打开localhost8100。
