You can use :

<code>node-localstorage</code> npm module to use <code>localStorage</code> at the <a href="/questions/tagged/nodejs" class="post-tag" title="show questions tagged &#39;nodejs&#39;" rel="tag">nodejs</a> server side.

<pre><code>var LocalStorage = require('node-localstorage').LocalStorage,
localStorage = new LocalStorage('./scratch');
</code></pre>

blocks|key|584581|text|如果你指的是html5+localStorage，因为node.js是一种服务器端技术，所以没有这样的东西。HTML5+localStorage是支持的客户端功能|type|unstyled|depth|inlineStyleRanges|entityRanges|data|584582|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

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

blocks|key|369062|text|对于Node.js，您可以使用HandyStorage，这是一个快速且小巧的npm包，它像state一样处理数据。下面是一个示例：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|369063|const+HandyStorage+=+require('handy-storage');

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

storage.setState({

++++lastname:+'Sh',
++++friends:+[
++++++++'Jane',
++++++++'John'
++++],
++++visited:+storage.state.visited+%7C%7C+0
})

storage.setState({
++++visited:+storage.state.visited+%2B+1
})|code-block|syntax|javascript|369064|它会自动更改JSON文件，只需尝试一下！|369065|entityMap|0|LINK|mutability|MUTABLE|url|https://www.npmjs.com/package/handy-storage^0|19|5|F|C|0|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@$9|V|A|W|B|C]]|D|@$9|X|A|Y|1|Z]]|E|$]]|$1|F|3|G|5|H|7|10|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|11|8|@]|D|@]|E|$]]|$1|M|3|-4|5|6|7|12|8|@]|D|@]|E|$]]]|N|$O|$5|P|Q|R|E|$S|T]]]]

For Node.js you can use <a href="https://www.npmjs.com/package/handy-storage" rel="nofollow noreferrer">HandyStorage</a>, a fast and small npm package which behaves data like a <code>state</code>
Here's an example:

<pre><code>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
})
</code></pre>

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

blocks|key|584748|text|服务器永远不能访问LocalStorage。永远不会。这将是一个巨大的安全问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|584749|如果需要将其发送到服务器，则必须有一个客户端JS脚本来检索它，然后将其作为Ajax或POST请求的一部分发送到服务器。|584750|当您需要在服务器和客户端之间定期传递少量数据时，Cookie工作得很好。|584751|如果您需要长期存储数据，则服务器上的数据库是最好的。|584752|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

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

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.

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

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

We can not save to localStorage on Node.js.

I tried searching the web for a node module that can access the client's localStorage but wasn't able to find anything. Anyone know of one?

How to access localStorage in node.js?

数据库

服务器

HTML5

JSON

我尝试在网络上搜索可以访问客户端localStorage的节点模块，但什么也找不到。有谁知道一个吗？
