在这篇文章，我们将把我们已经非常出色的弹出式浏览器扩展变得更加个性化。

为了维护用户选择的内容，我们将利用 chrome 的存储能力。

增加浏览器扩展存储权限

修改manifest.json，在权限数组新增storage

{
  "permissions": ["alarms", "notifications", "storage"]
}

编写扩展主体

import {useState} from 'react'

const colorMatch = {
  indigo: 'bg-indigo-400',
  pink: 'bg-pink-400',
  purple: 'bg-purple-400'
}

export function App() {
  const [color, setColor] = useState('indigo')

  const createNotification = () => {
    chrome.alarms.create('motivation_alarm', {
      periodInMinutes: 60
    })
    window.close()
  }

  const stopNotification = () => {
    chrome.alarms.clearAll()
    window.close()
  }

  chrome.storage.sync.get('color', (storedColor) => {
    setColor(storedColor.color)
  })

  const pickColor = (pickedValue) => {
    setColor(pickedValue)
    chrome.storage.sync.set({color: pickedValue})
  }

  return (
    <div
      className={`flex flex-col items-center justify-center w-screen h-auto ${colorMatch[color]} p-4`}
    >
      <select
        onChange={(event) => pickColor(event.target.value)}
        value={color}
        className="bg-gray-50 border border-gray-300 text-gray-900 text-sm rounded-lg focus:ring-indigo-500 focus:border-indigo-500 block w-full p-2.5 dark:bg-gray-700 dark:border-gray-600 dark:placeholder-gray-400 dark:text-white dark:focus:ring-indigo-500 dark:focus:border-indigo-500"
      >
        <option>Pick a color</option>
        <option value="indigo">Indigo</option>
        <option value="pink">Pink</option>
        <option value="purple">Purple</option>
      </select>
      <br />
      <button
        className="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 text-2xl px-4 rounded"
        onClick={createNotification}
      >
