flattn

There are lots of flattening libraries out there, but I decided to write my own because I wanted to write my own :)

Mainly, I wanted to write it in the latest ES6 that nodejs 6.x gives us, with beautiful things like default params!

If you use this in a frontend project, make sure it gets transpiled!

Getting started

npm install flattn

Then, in your JS file:

const flattn = require('flattn');

const myCrazyDeepObject = {
  nested: {
    stuff: 'here'
  }
};

flattn(myCrazyDeepObject); // outputs a beautifully flat object

Options

flattn(object, {}) takes a couple optional params:

• crush (array) - this will remove a nesting namespace from the final product (ie. if you crush [ 'metadata' ], then { metadata: { hello: 'world' }} will return { hello: 'world' })
• stringifyNull (boolean) - this will turn nulls into ''
• separator (string) - by default, this lib uses an underscore. But, if you want something else...
• pruneFunctions (boolean) - if the value of a key is a function, then you can opt to not have those in the result
