pogo-builder v1.1.1

POGO

Installation

npm i pogo-builder

Usage

Path: The first argument is a path string. With in the path a : represents a seperate key and defaults to an object. The terminal key in a path defaults to an object if no data is provided. [] at the end of a key represents an array; to have an array mid path, prefix the : with a []. ex: foo:bar[]:fizz becomes { foo: bar: [{ fizz: { } }] }.

Data: The second argument is any data you want to be stored at the end of the object described in the path.

Reducing Object: The third argument is the object to add to, defaults to an object. If the terminal keys overlap with existing data in both, the data argument will overwrite other values. However, if both are objects or both are arrays they will be combined. (Order preference to the data in the reducing object's array.)

// ex:
pogo(`foo:bar`, true, { foo: { bar: false } }) // => { foo: { bar: true } }
pogo(`foo:bar`, { fizz: {} }, { foo: { bar: { buzz: {} } } }) // => { foo: { bar: { buzz: {}, fizz: {} } } }
pogo(`foo:bar[]`, 5, { foo: { bar: [9] } }) // => { foo: { bar: [9, 5] } }

// more examples
const pogo = require('pogo')
// simple object
pogo('foo:bar') // => { foo: { bar: {} } }
// simple object with arr
const pojo = pogo('foo:bar[]') // => { foo: { bar: [] } }
pogo('foo:bar') // => { foo: { bar: {} } }
// simple object with arr and with data
const pojo = pogo('foo:bar[]', { fizz: true }) // => { foo: { bar: [{bar: true}] } }
// can add to and merge complex objects or arrays
pogo('foo:bar[]', { buzz: true }, pojo) // => { foo: { bar: [{ fizz: true }, { buzz: true }] })

Motivation

Having written so many elasticsearch queries out by hand I wanted a simple way to build them without being tied to orm or something bulky. Pogo allows you to maintain fine control over queries while simplifying writing them.
