@ianwalter/find-nested

A utility that searches through nested layers for values

About

findNested and findAllNested are a couple of simple recursive functions that return the first value or all values (respectively) that are assigned to a given key and/or pass a given filter function. I wrote this in order to more easily retrieve values from JSON objects with multiple layers of nesting that were generated from converting API Blueprints to JSON with blueline.

Installation

yarn add @ianwalter/find-nested

Usage

const { findNested, findAllNested } = require('@ianwalter/find-nested')

// Return the first value for someKeyName in obj:
findNested(obj, 'someKeyName')

// Return the first value for soneKeyName in obj that also causes the given
// descriminator function to return true:
findNested(obj, 'someKeyName', val => val.isActive)

// Returns all objects in an array (thats why the key name is undefined) that
// have a headers property with an array that contains at least one object with
// a value property that includes the string 'json'.
const hasJsonBody = obj => obj.headers.some(h => h.value.includes('json'))
findAllNested(obj, undefined, hasJsonBody)
