lowdb/lib/fp
⚠️ Experimental
lowdb/lib/fp lets you use lodash/fp, Ramda or simple JavaScript functions with lowdb.
It can help reducing the size of your bundle.js
Usage
import low from 'lowdb/lib/fp'
import { concat, find, sortBy, take, random } from 'lodash/fp'
const db = low()
// Get posts
const defaultValue = []
const posts = db('posts', defaultValue)
// replace posts with a new array resulting from concat
// and persist database
posts.write(
concat({ title: 'lowdb is awesome', views: random(0, 5) })
)
// Find post by id
const post = posts(
find({ id: 1 })
)
// Find top 5 fives posts
const popular = posts([
sortBy('views'),
take(5)
])
API
lowdb/lib/fp shares the same API as lowdb except for the two following methods.
db(path, [defaultValue])([funcs])
Returns a new array or object without modifying the database state.
db('posts')(filter({ published: true }))
db(path, [defaultValue]).write([funcs])
Add .write when you want the result to be written back to path
db('posts').write(concat(newPost))
db('user.name').write(set('typicode'))
