|
||
* [💯Omiu 打造的 Omi Admin](https://tencent.github.io/omi/packages/admin/dist/index.html)
|
||
|
||
|
||
使用 TypeScript 开发跨框架的按钮组件:
|
||
|
||
```ts
|
||
import { tag, WeElement, h, extractClass } from 'omi'
|
||
import * as css from './index.scss'
|
||
|
||
interface Props {
|
||
size?: 'medium' | 'small' | 'mini',
|
||
type?: 'primary' | 'success' | 'warning' | 'danger' | 'info' | 'text'
|
||
plain?: boolean,
|
||
round?: boolean,
|
||
circle?: boolean,
|
||
loading?: boolean,
|
||
disabled?: boolean,
|
||
icon?: string,
|
||
autofocus?: boolean,
|
||
nativeType?: 'button' | 'submit' | 'reset',
|
||
block?: boolean
|
||
text?: string
|
||
}
|
||
|
||
@tag('o-button')
|
||
export default class Button extends WeElement<Props>{
|
||
static css = css
|

|
||
disabled: false,
|
||
autofocus: false,
|
||
nativeType: 'button',
|
||
block: false
|
||
}
|
||
|
||
static propTypes = {
|
||
size: String,
|
||
type: String,
|
||
plain: Boolean,
|
||
round: Boolean,
|

|
||
}
|
||
|
||
render(props) {
|
||
return <button disabled={props.disabled} {...extractClass(props, 'o-button', {
|
||
['o-button-' + props.type]: props.type,
|

{props.loading && <i class='icon-loading'></i>}
|
||
{props.text}
|
||
<slot></slot>
|
||
</button>
|
||
}
|
||
}
|
||
```
|
||
|
||
|
||
## 快速开始开发项目
|
||
|
||
```bash
|
||
$ npm i omi-cli -g # install cli
|
||
$ omi init my-app # 初始化项目，也可以在空目录里执行 'omi init'
|
||
$ cd my-app # 如果在空目录里执行 'omi init' 忽略这条命令
|
||
$ npm start # 开发
|
||
$ npm run build # 编译发布
|
||
```
|
||
|
||
> `npx omi-cli init my-app` 也支持(要求 npm v5.2.0+)
|
||
|
||
## 快速开始开发跨框架组件

```bash
|
||
$ npm i omi-cli -g # install cli
|
||
$ omi init-component my-component # 初始化项目，也可以在空目录里执行 'omi init'
|
||
$ cd my-app # 如果在空目录里执行 'omi init' 忽略这条命令
|
||
$ npm start # 开发
|
||
$ npm run build # 编译发布
|
||
```
|

### 特性
|
||
|
||
- 框架无关，任何框架可以使用 Omi 自定义元素
|
||
- 提供桌面、移动和小程序整体解决方案
|
||
- 无状态视图的架构设计
|
||
- 小巧的尺寸和[高性能](https://tencent.github.io/omi/packages/omi/examples/perfs/)
|
||
- 对 custom elements 友好, 通过字符串 `'0'`或者`'false'`传递 `false`，[通过`:`和`Omi.$`传递任意复杂类型](https://github.com/Tencent/omi/releases/tag/v6.8.0)
|
||
- 拥有官方跨框架 UI 组件库 - [omim](https://tencent.github.io/omi/packages/omim/docs/build/cn.html)
|
||
- [很容易通过 extend api 实现双向绑定](https://codepen.io/omijs/pen/aeLYjx)
|
||
- 增强了 CSS, [支持 rpx 单位](https://github.com/Tencent/omi/releases/tag/v4.0.26)，基于 **750** 屏幕宽度
|
||
- [基于 Shadow/Light Dom 设计](https://developers.google.cn/web/fundamentals/web-components/shadowdom?hl=zh-cn)
|
||
- 利用 [Chrome 开发工具扩展 ](https://github.com/f/omi-devtools)轻松调试，[从 Chrome 应用商店安装](https://chrome.google.com/webstore/detail/omijs-devtools/pjgglfliglbhpcpalbpeloghnbceocmd/related)
|
||
- 符合浏览器的发展趋势以及 API 设计理念
|
||
- [**Web Components**](https://developers.google.com/web/fundamentals/web-components/) + [**JSX**](https://reactjs.org/docs/introducing-jsx.html) 融合为一个框架 Omi
|
||
- Web Components 也可以数据驱动视图, `UI = fn(data)`
|
||
- JSX 是开发体验最棒(智能提示)、[语法噪音最少](https://github.com/facebook/jsx#why-not-template-literals)、图灵完备的 UI 表达式，模板引擎不完备，模板字符串完备但是语法噪音太大
|
||
- 看看 [Facebook React 和 Web Components 对比优势](https://www.cnblogs.com/rubylouvre/p/4072979.html)，Omi 融合了各自的优点，而且给开发者自由的选择喜爱的方式
|
||
- `Shadow/Light DOM` 与 `Virtual DOM` 融合，Omi 既使用了`虚拟 DOM`，也是使用真实 `Shadow DOM`，让视图更新更准确更迅速
|
||
- 局部 CSS 最佳解决方案(`Shadow DOM`)，社区为局部 CSS 折腾了不少框架和库(使用 js 或 json 写样式，如:`Radium`，`jsxstyle`，`react-style`；与 webpack 绑定使用生成独特的 className `文件名—类名—hash值`，如：`CSS Modules`，`Vue`)，还有运行时注入`scoped atrr` 的方式，都是 hack 技术；`Shadow DOM Style` 是最完美的方案
|
||
|
||
对比同样开发 TodoApp， Omi 和 React 渲染完的 DOM 结构，Omi 使用 Shadow/Light DOM 隔离样式和语义化结构:
|
||
|
||
| **Omi** | **React** |
|
||

* [build env doc](https://facebook.github.io/create-react-app/docs/adding-custom-environment-variables#referencing-environment-variables-in-the-html)
|
||
|
||
比如在 windows 下:
|
||
|
||
```json
|
||
"scripts": {
|
||
"start": "node scripts/start.js",
|
||
"_build": "node scripts/build.js",
|
||
"build":"set PUBLIC_URL=https://fe.wxpay.oa.com/dv&& npm run _build"
|
||
}
|
||
```
|
||
|
||
在 mac os 中:
|
||
|
||
```json
|
||
"scripts": {
|
||
"start": "node scripts/start.js",
|
||
"_build": "node scripts/build.js",
|
||
"build":"PUBLIC_URL=https://fe.wxpay.oa.com/dv npm run _build",
|
||
"fix": "eslint src --fix"
|
||
},
|
||
```
|
||
|
||
如果你只想使用相对地址:
|
||
|
||
```
|
||
"build":"set PUBLIC_URL=.&& npm run _build" //windows
|
||
"build":"PUBLIC_URL=. npm run _build", //mac os
|
||
``` -->
|
||
|
||
### 项目模板
|
||
|
||
| **Template Type**| **Command**| **Describe**|
|
||
| ------------ | -----------| ----------------- |
|
||
|基础模板(v3.3.0+)|`omi init my-app`| 基础模板，支持 omi 和 omio(IE8+)|
|
||
|Kbone Template|`omi init-kbone my-app` | 使用 omi 开发小程序或者 Web|
|
||
|
||
### Hello Element
|
||
|
||
先创建一个自定义元素:
|
||
|
||
```js
|
||
import { define, WeElement } from 'omi'
|
||
|
||
define('hello-element', class extends WeElement {
|
||
onClick = evt => {
|
||
// trigger CustomEvent
|
||
this.fire('Abc', { name: 'dntzhang', age: 12 })
|
||
evt.stopPropagation()
|
||
}
|
||
|
||
//如果需要在 html 里直接使用 <hello-element></hello-element>，必须声明 propTypes
|
||
static propTypes = {
|
||
msg: String
|
||
}
|
||
|
||
static css = `
|
||
div {
|
||
color: red;
|
||
cursor: pointer;
|
||
}`
|
||
|
||
render(props) {
|
||
return (
|
||
<div onClick={this.onClick}>
|
||
Hello {props.msg}
|
||
<div>Click Me!</div>
|
||
</div>
|
||
)
|
||
}
|
||
})
|
||
```
|
||
|
||
使用该元素:
|
||
|
||
```js
|
||
import { define, render, WeElement } from 'omi'
|
||
import './hello-element'
|
||
|
||
define('my-app', class extends WeElement {
|
||
data = { abc: 'abc' }
|
||
|
||
// define CustomEvent Handler
|
||
onAbc = evt => {
|
||
// get evt data by evt.detail
|
||
this.data.abc = ' by ' + evt.detail.name
|
||
this.update()
|
||
}
|
||
|
||
static css = `
|
||
div{
|
||
color: green;
|
||
}`
|
||
|
||
render(props) {
|
||
return (
|
||
<div>
|
||
Hello {this.data.abc}
|
||
<hello-element
|
||
onAbc={this.onAbc}
|
||
msg="WeElement"
|
||
/>
|
||
</div>
|
||
)
|
||
}
|
||
})
|
||
|
||
render(<my-app name="Omi v4.0" />, 'body')
|
||
```
|
||
|
||
告诉 Babel 把 JSX 转化成 Omi.h() 的调用:
|
||
|
||
``` json
|
||
{
|
||
"presets": ["env", "omi"]
|
||
}
|
||
```
|
||
|
||
需要安装下面两个 npm 包支持上面的配置:
|
||
|
||
``` bash
|
||
"babel-preset-env": "^1.6.0",
|
||
"babel-preset-omi": "^0.1.1",
|
||
```
|
||
|
||
如果你使用 babel7，也可以使用如下包和配置：
|
||
|
||
```bash
|
||
npm install --save-dev @babel/preset-env
|
||
npm install --save-dev @babel/preset-react
|
||
```
|
||
|
||
```js
|
||
{
|
||
"presets": [
|
||
"@babel/preset-env",
|
||
[
|
||
"@babel/preset-react",
|
||
{
|
||
"pragma": "Omi.h",
|
||
"pragmaFrag": "Omi.h.f"
|
||
}
|
||
]
|
||
]
|
||
}
|
||
```
|
||
|
||
如果不想把 css 写在 js 里，你可以使用 webpack [to-string-loader](https://www.npmjs.com/package/to-string-loader), 比如下面配置:
|
||
|
||
``` js
|
||
{
|
||
test: /[\\|\/]_[\S]*\.css$/,
|
||
use: [
|
||
'to-string-loader',
|
||
'css-loader'
|
||
]
|
||
}
|
||
```
|
||
|
||
如果你的 css 文件以 `_` 开头, css 会使用 to-string-loader, 如：
|
||
|
||
``` js
|
||
import { tag, WeElement render } from 'omi'
|
||
|
||
define('my-app', class extends WeElement {
|
||
|
||
css = require('./_index.css')
|
||
...
|
||
...
|
||
...
|
||
```
|
||
|
||
你也可以忘掉这一对繁琐的配置直接使用 omi-cli，不需要你配置任何东西。

<!-- ### TodoApp
|
||
|
||
下面列举一个相对完整的 TodoApp 的例子:
|
||
|
||
```js
|
||
import { define, render, WeElement } from 'omi'
|
||
|
||
define('todo-list', class extends WeElement {
|
||
static propTypes = {
|
||
items: Array
|
||
}
|
||
|
||
render(props) {
|
||
return (
|
||
<ul>
|
||
{props.items.map(item => (
|
||
<li key={item.id}>{item.text}</li>
|
||
))}
|
||
</ul>
|
||
)
|
||
}
|
||
})
|
||
|
||
define('todo-app', class extends WeElement {
|
||
items = []
|
||
text = ''
|
||
|
||
render() {
|
||
return (
|
||
<div>
|
||
<h3>TODO</h3>
|
||
<todo-list items={this.items} />
|
||
<form onSubmit={this.handleSubmit}>
|
||
<input
|
||
id="new-todo"
|
||
onChange={this.handleChange}
|
||
value={this.text}
|
||
/>
|
||
<button>Add #{this.items.length + 1}</button>
|
||
</form>
|
||
</div>
|
||
)
|
||
}
|
||
|
||
handleChange = e => {
|
||
this.text = e.target.value
|
||
}
|
||
|
||
handleSubmit = e => {
|
||
e.preventDefault()
|
||
if (!this.text.trim().length) {
|
||
return
|
||
}
|
||
this.items.push({
|
||
text: this.text,
|
||
id: Date.now()
|
||
})
|
||
this.text = ''
|
||
this.update()
|
||
}
|
||
})
|
||
|
||
render(<todo-app />, 'body')
|
||
``` -->
|
||
|
||
<!--
|
||
使用 Store 体系可以告别 update 方法，基于 Proxy 的全自动属性追踪和更新机制。强大的 Store 体系是高性能的原因，除了靠 props 决定组件状态的组件，其余组件所有 data 都挂载在 store 上,
|
||
|
||
```js
|
||
export default {
|
||
data: {
|
||
items: [],
|
||
text: '',
|
||
firstName: 'dnt',
|
||
lastName: 'zhang',
|
||
fullName: function () {
|
||
return this.firstName + this.lastName
|
||
},
|
||
globalPropTest: 'abc', //更改我会刷新所有页面,不需要再组件和页面声明data依赖
|
||
ccc: { ddd: 1 } //更改我会刷新所有页面,不需要再组件和页面声明data依赖
|
||
},
|
||
globalData: ['globalPropTest', 'ccc.ddd'],
|
||
add: function () {
|
||
if (!this.data.text.trim().length) {
|
||
return;
|
||
}
|
||
this.data.items.push({
|
||
text: this.data.text,
|
||
id: Date.now()
|
||
})
|
||
this.data.text = ''
|
||
}
|
||
//默认 false，为 true 会无脑更新所有实例
|
||
//updateAll: true
|
||
}
|
||
```
|
||
|
||
自定义 Element 需要声明依赖的 data，这样 Omi store 根据自定义组件上声明的 data 计算依赖 path 并会按需局部更新。如:
|
||
|
||
```js
|
||
define('todo-app', class extends WeElement {
|
||
static get data() {
|
||
//如果你用了 store，这个只是用来声明依赖，按需 Path Updating
|
||
return { items: [], text: '' }
|
||
}
|
||
...
|
||
...
|
||
...
|
||
handleChange = (e) => {
|
||
this.store.data.text = e.target.value
|
||
}
|
||
|
||
handleSubmit = (e) => {
|
||
e.preventDefault()
|
||
this.store.add()
|
||
}
|
||
})
|
||
```
|
||
|
||
* 数据的逻辑都封装在了 store 定义的方法里 (如 store.add)
|
||
* 视图只负责传递数据给 store （如上面调用 store.add 或设置 store.data.text）
|
||
|
||
需要在 render 的时候从根节点注入 store 才能在所有自定义 Element 里使用 this.store:
|
||
|
||
```js
|
||
render(<todo-app></todo-app>, 'body', store)
|
||
```
|
||
|
||

|
||
|
||
总结一下:
|
||
|
||
* store.data 用来列出所有属性和默认值(除去 props 决定的视图的组件)
|
||
* 组件和页面的 data 用来列出依赖的 store.data 的属性 (omi 会记录 path)，按需更新
|
||
* 如果页面简单组件很少，可以 updateAll 设置成 true，并且组件和页面不需要声明 data，也就不会按需更新
|
||
* globalData 里声明的 path，只要修改了对应 path 的值，就会刷新所有页面和组件，globalData 可以用来列出所有页面或大部分公共的属性 Path -->

## Mitt
|
||
|
||
如果不想使用 store 的 data 体系，也可以使用发布订阅模式。比如在 Omi 中使用 [mitt](https://github.com/developit/mitt) 跨组件通讯:
|
||
|
||
* [cross-component-communication](https://github.com/Tencent/omi/blob/master/packages/omi-30-seconds/README.md#cross-component-communication) -->

如果你想要兼容 IE11,请使用 `omi-mobx` 代替 omi 自带的 observe，往下看..
|
||
|
||
### Omi Mobx
|
||
|
||
```js
|
||
import { tag, WeElement } from "omi"
|
||
import { observe } from "omi-mobx"
|
||
|
||
@observe
|
||
@tag("my-app")
|
||
class MyApp extends WeElement {
|
||
install() {
|
||
this.data.name = "omi"
|
||
}
|
||
|
||
onClick = () => {
|
||
this.data.name = "Omi V4.0"
|
||
}
|
||
|
||
render(props, data) {
|
||
return (
|
||
<div onClick={this.onClick}>
|
||
<h1>Welcome to {data.name}</h1>
|
||
</div>
|
||
)
|
||
}
|
||
}
|
||
``` -->

||
### 生命周期
|
||
|
||
| 钩子方法 | 触发时机 |
|
||
| ---------------- | -------------------------------------------- |
|
||
| `install` | 初始化安装 |
|
||
| `installed` | 插入到文档之后且安装完成 |
|
||
| `uninstall` | 从文档中卸载移除 |
|
||
| `beforeUpdate` | update 之前 |
|
||
| `updated` | update 之后 |
|
||
| `beforeRender` | `render()` 之前 |
|
||
| `receiveProps` | 父组件更新时候触发, 返回 false 可以阻止更新 |
|
||
|
||
### 查看所有注册的元素
|
||
|
||
```js
|
||
console.log(Omi.elements)
|
||
