### promise-dictionary（获取异步数据字典的解决方案）



适用场景:

* 组件后续的组件渲染所依赖的数据字典需要从后台异步获取的场景
* 数据字典返回值是固定值



> 高阶组件版本

```react
import React from "react";
import {injectDictionary} from "@yushicheng/promise-dictionary";


@injectDictionary({
  test: Promise.resolve(111)
})
class TestinjectDictionary extends React.Component {

  constructor(props) {
    super(props);
    this.state = {};
  };

  render() {
    const { $dictionary: { test } } = this.props;
    return (
      <div>
        <div>测试高阶组件</div>
        <div>{test}</div>
      </div>)
  };
};

export default TestinjectDictionary;
```



> hooks版本

```react
import React from "react"
import {useDictionary} from "@yushicheng/promise-dictionary";


export default function TestUseDictionary(props) {
  const dictionaryValue = useDictionary(Promise.resolve(445454))
  return (
    <div>
      <div>测试useDictionary:</div>
      <div>{dictionaryValue}</div>
    </div>)
};
```
