Lightweight Javascript DB for use in Node.js
提问by ConfusedNoob
Anybody know of a lightweight yet durable database, written in Javascript, that can be used with Node.js.
任何人都知道用 Javascript 编写的轻量级但持久的数据库，可以与 Node.js 一起使用。
I don't want the 'weight' of (great) solutions like Mongo or Couch. A simple, in memory JS database with the capability to persist to disk as a file would be enough. I would only use it to store small amounts of data.
我不想要像 Mongo 或 Couch 这样的（伟大的）解决方案的“重量”。一个简单的内存 JS 数据库能够作为文件持久化到磁盘就足够了。我只会用它来存储少量数据。
Requirements:
要求：
- can run in process with a node.js server application
- can save the whole database to disk and recover after a failure
- NO need for atomic writes or transaction supports
- fast queries and sorting would be nice
- only needs to support small data volumes, up to 1MB in total
- 可以与 node.js 服务器应用程序一起运行
- 可以将整个数据库保存到磁盘并在失败后恢复
- 不需要原子写入或事务支持
- 快速查询和排序会很好
- 只需要支持小数据量，总共最大1MB
I've come across TAFFY db so far but it really doesn't seem optimized for use in Node.js. Anybody seen what I'm looking for out there?
到目前为止，我遇到了 TAFFY db，但它似乎并没有针对在 Node.js 中使用进行优化。有人看到我在外面寻找什么吗？
Thanks
谢谢

I'm only familiar with Mongo and Couch, but there's also one named Persistence.
我只熟悉 Mongo 和 Couch，但也有一个名为Persistence 的。

I had the same requirements as you but couldn't find a suitable database. nStore was promising but the API was not nearly complete enough and not very coherent.
我和你有同样的要求，但找不到合适的数据库。nStore 很有前途，但 API 还不够完整，也不是很连贯。
That's why I made NeDB, which a dependency-less embedded database for Node.js projects. You can use it with a simple require(), it is persistent, and its API is the most commonly used subset of the very well-known MongoDB API.
这就是我制作NeDB的原因，它是一个用于 Node.js 项目的无依赖嵌入式数据库。您可以将它与简单的 一起使用require()，它是持久的，并且它的 API 是非常著名的 MongoDB API 中最常用的子集。

NeDBseems to be what you are looking for. From the blurb:
NeDB似乎正是您要找的。从简介：
Embedded persistent database for Node.js, written in Javascript, with no dependency (except npm modules of course). You can think of it as a SQLite for Node.js projects, which can be used with a simple require statement. The API is a subset of MongoDB's. You can use it as a persistent or an in-memory only datastore.
Node.js 的嵌入式持久数据库，用 Javascript 编写，没有依赖性（当然 npm 模块除外）。您可以将其视为 Node.js 项目的 SQLite，可以与简单的 require 语句一起使用。API 是 MongoDB 的一个子集。您可以将其用作持久或仅内存中的数据存储。

Take a look at http://www.tingodb.com. I believe it does what you looking for. Additionally it fully compatible with MongoDB API. This reduces implementation risks and gives you option to switch to heavy solution as your app grows.
看看http://www.tingodb.com。我相信它可以满足您的需求。此外，它与 MongoDB API 完全兼容。这降低了实施风险，并让您可以选择随着应用程序的增长而切换到重型解决方案。

Try nStore, it seems like a nice key/value lightweight dembedded db for node. See https://github.com/creationix/nstore
试试 nStore，它似乎是一个很好的键/值轻量级节点嵌入数据库。见https://github.com/creationix/nstore

I had trouble with SQLite3, nStore and Alfred.
我在使用 SQLite3、nStore 和 Alfred 时遇到了麻烦。
What works for me is node-dirty:
对我有用的是node-dirty：
path = "#{__dirname}/data/messages.json"
messages = db path
message = 'text': 'Lorem ipsum dolor sit...'
messages.on "load", ->
messages.set 'my-unique-key', message, ->
console.log messages.get('my-unique-key').text
messages.forEach (key, value) ->
console.log "Found key: #{key}, val: %j", value
messages.on "drain", ->
console.log "Saved to #{path}"
