Lightweight Javascript DB for use in Node js

Question

Anybody know of a lightweight yet durable database  written in Javascript  that can be used with Node js    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    Requirements    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   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   Thanks

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   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   https   github com louischatriot nedb
