If you mean html 5 localStorage, there's no such a thing since node.js is a server-side technology. Html 5 localStorage is a client side feature supported

如果您的意思是 html 5 localStorage，则没有这样的事情，因为 node.js 是一种服务器端技术。Html 5 localStorage 是支持的客户端功能

Found this store

找到这个 store

// Store current user 
store.set('user', { name:'Marcus' })

// Get current user 
store.get('user')

// Remove current user 
store.remove('user')

// Clear all keys 
store.clearAll()

// Loop over all stored values 
store.each(function(value, key) {
    console.log(key, '==', value)
})

LocalStorage is never accessible by the server. Ever. It would be a huge security issue.

服务器永远无法访问 LocalStorage。曾经。这将是一个巨大的安全问题。

If you need to send it to a server, then you have to have a client-side JS script which retrieves it, and then sends it to the server as part of an Ajax or POST request.

如果您需要将它发送到服务器，那么您必须有一个客户端 JS 脚本来检索它，然后将它作为 Ajax 或 POST 请求的一部分发送到服务器。

Cookies work well for when you need to pass small amounts of data regularly between server and client.

当您需要在服务器和客户端之间定期传递少量数据时，Cookie 非常有用。

Databases on your server are best if you need to store data long-term.

如果您需要长期存储数据，则服务器上的数据库是最佳选择。

For Node.js you can use HandyStorage, a fast and small npm package which behaves data like a stateHere's an example:

对于 Node.js，您可以使用HandyStorage，这是一个快速且小型的 npm 包，其行为类似于state以下示例：

const HandyStorage = require('handy-storage');

const storage = new HandyStorage('./store.json');

storage.setState({
    name: 'Alireza',
    lastname: 'Sh',
    friends: [
        'Jane',
        'John'
    ],
    visited: storage.state.visited || 0
})

storage.setState({
    visited: storage.state.visited + 1
})

It automatically changes the JSON file, just give it a try!

它会自动更改 JSON 文件，试试看吧！
