LowDB构建在 Lo-Dash, 这使得它非常不同、独特，相比其他往往是基于MongoDBAPI的无服务器数据库。
LowDB powers JSON Server and JSONPlaceholder.
Usage
var low = require('lowdb') low('songs').insert({title: 'low!'}) Database is automatically created and saved to db.json in a readable format.
{ "songs": [ { "title": "low!", "id": "e31aa48c-a9d8-4f79-9fce-ded4c16c3c4c" } ] } To query data, you can use Lo-Dash methods.
var songs = low('songs').where({ title: 'low!' }).value() Or LowDB equivalent short syntax.
var songs = low('songs', { title: 'low!' }) Changes can also be monitored.
low.on('add', function(name, object) { console.log(object + 'added to' + name) }) Benchmark
