normalize-api

This function pulls out models from nested object. And removes model nesing alltogether. Makes data easy to store in redux store

Single object

import normalize from 'normalize-api'


const post = {
  id: 1,
  title: 'My first post',
  user: { id: 4, name: 'Post Writer' },
  comments: [
    {
      id: 1,
      message: 'First comment',
      post_id: 1,
      user: { id: 1, name: 'User 1' }
    },
    {
      id: 2,
      message: 'Second comment',
      post_id: 1,
      user: { id: 2, name: 'User 2' }
    },
    {
      id: 3,
      message: 'Third comment',
      post_id: 1,
      user: { id: 2, name: 'User 2' }
    }
  ]
}

const models = normalize(post, 'post')

/* response of normalize
