What Hacker News says
13 sourcesYeah, it's called EJDB. https://github.com/Softmotions/ejdb
In LiteDB – A .NET NoSQL Document Store in a Single Data FileEJDB [0] is pretty good and seems to be actively developed again after a period of inactivity. It uses BSON rather than JSON directly but close enough, and the queries are modelled after Mongo too.
I made a C++14 wrapper [1] a while ago which will probably still work unless EJDB itself had some drastic API changes. (I also have a C++14/1y BSON/JSON library [2] that's handy for working with EJDB, but is a bit of a playground for template metaprogramming so compile times will explode with certain functionality).
The main problem with EJDB is that it's not crash tolerant so you need signal handlers to attempt a graceful flush/close on a global handle.

In JSONlite – A self-contained, serverless, zero-configuration, JSON document storeIt is not clear to me from the committed CoffeeScript how this will work, but is this going to build on top of ejdb project [0] mentioned here a month or so ago?
