reql-pointfree#

Functional RethinkDB functions for point free programming

works on the RethinkDB official driver and rethinkdbdash

Installation#

just

npm install --save reql-pointfree

and you're set

Usage#

import createReQL from 'reql-pointfree'
const { db, compose, filter, take, table, add, execute } = createReQL(r) // the rethink driver

// create a `reql` function to call your ReQLs
let reql = execute(r.connection) // rethinkdbdash is just execute()

// some functions
let exclaim = add('!') // r.something().add('!')
let head = take(0) // r.something()(0)
let getName = map(take('name')) // r.something().map(e => e('name'))
let filterSuperheroes = filter({ isSuperhero: true }) // r.something().filter({ isSuperhero: true })
let users = table('users') // r.table('users')
let earth = db('earth') // r.db('earth')

let getSuperheroesFromUsers = compose(filterSuperheroes, users, db)
let getNameOfFirstSuperheroFromUsers = compose(getName, head, getSuperheroesFromUsers)

// then, in your app..
reql(getNameOfFirstSuperheroFromUsers).then(....)
// and even
reql(getSuperheroesFromUsers).then(...)

this is the concept. you don't have to compose everything, but you CAN compose things. which is great IMO.
