在哪里/如何存储数据集合

Where/how to store a collection of data

本文关键字：数据 数据集 集合 存储 何存储 在哪里      更新时间：2023-09-26

我有一个时区数据集(见下文)，我需要在我的应用程序的不同部分访问。

我习惯于OO方法，我将它存储在类方法中，例如在Timezone中。all_zones (Ruby)，可以从任何地方访问。

是否有可能做类似的事情，即有一个组件，唯一的目的是存储这些数据，然后我可以从我的应用程序的不同部分检索?

否则，还有什么更快捷的方式来存储/检索这些静态数据呢?

const timezone_objects = [

如果这是一个真正的静态资源，它不会被修改，你可以把它放在一个自己的js文件中，并在你需要它的组件中导入/需要它

您可以使用redux

对于静态数据，您可以创建一个data.js文件: 
export default function(){
    return[
        {value: "-12.00", text: "(GMT -12:00) Eniwetok, Kwajalein"},
        {value: "-11.00", text: "(GMT -11:00) Midway Island, Samoa"}
    ]
}

然后你可以把它加载到你的react应用中，像这样:

import getData from './data'

然后，例如在渲染方法:

render(){
    console.log(getData())
    ...
