如何将这个功能性 React 组件更改为使用 Recompose 的组件?

How would one change this Functional React Component to one that uses Recompose?

我有以下功能组件,我有兴趣了解如何将其更改为 branch 增强组件,而不是 if 声明。

import React from 'react'
import PropTypes from 'prop-types'
import { Button, Icon, Label } from 'semantic-ui-react'
import { Link } from 'react-router-dom'
import { setPropTypes, branch } from 'recompose'

const LoginOrMiniProfile = ({presence}) => {
    if (presence.account) {
        return (
            <Link to='/profile'>
                <Label>
                    <Icon name='user circle outline' />
                    {presence.account.firstName}
                </Label>
            </Link>
        )
    } else {
        return (
            <div>
                <Button primary className={`login ${presence.loading && 'loading'}`}>Signup</Button>
                <Button className={`login ${presence.loading && 'loading'}`}>Login</Button>
            </div>
        )
    }
}

export default setPropTypes({
    prensence: PropTypes.object.isRequired
})(LoginOrMiniProfile)

为了加分,如何使用 Recompose 访问和更改 Redux 存储中的 presence

这里是一个简单的例子来实现你想要的。您可以(并且应该)进行一些重构,例如在其他地方定义内联功能组件。

compose(
  connect(
    ({ presence }) => ({ presence }), // get presence from the redux store via `connect`
    {
      updatePresence: updatePresenceActionCreator // inject dispatch(updatePresence) to props
    }
  ),
  setPropTypes({
    prensence: PropTypes.object.isRequired,
    updatePresence: PropTypes.func.isRequired
  }),
  branch(
    ({ presence }) => presence.account,
    renderComponent(({ presence }) =>
      <Link to="/profile">
        <Label>
          <Icon name="user circle outline" />
          {presence.account.firstName}
        </Label>
      </Link>
    )
  )
)(({ 
  presence,
  updatePresence // you can update your presence by invoking this function
}) =>
  <div>
    <Button primary className={`login ${presence.loading && "loading"}`}>
      Signup
    </Button>
    <Button className={`login ${presence.loading && "loading"}`}>Login</Button>
  </div>
);
