node-embedded-db

Embedded persistent database for Node.js, with no dependency (except npm modules of course). The API is the same as MongoDB.

Why?

I needed to store data from another project ([https://github.com/louischatriot/braindead-ci](Braindead CI)). I needed the datastore to be standalone (i.e. no dependency except other Node modules) so that people can install the software using a simple npm install. I couldn't find one without bugs and a clean API so I made this one.

Installation, tests

It will be published as an npm module once it is finished. To launch tests: npm test. You

Performance

Speed

Performance is pretty good on the kind of datasets it is designed for (10,000 documents or less). On my machine (3 years old, no SSD), with a collection with 10,000 documents:

• An insert takes 0.1ms
• A read takes 5.7ms
• An update takes 62ms
• A deletion takes 61ms Read, update and deletion times are pretty much non impacted by the number of concerned documents. Inserts, updates and deletions are non-blocking. Read will be soon, too (but they are so fast it is not so important anyway).
