WaveDB

Javascript document database based on LevelDB.

This library is meant for sites with low to medium traffic demands running on a single machine. It does not require installing a separate database server and is portable, moving your data is just zipping up the database directory and copying it somewhere else.

Install

In Node.js: npm i wavedb

Usage

// Require library
const db = require('wavedb')()

// Create document, 'user' is the name of the model/collection
const result = await db('user').create({ email: '[email protected]' })

// Returns an object with the id
{ id: 'ck2a5xf2c0000okk3dbvz4n3i' }
