append-field

A W3C HTML JSON forms spec compliant field appender (for lack of a better name). Useful for people implementing application/x-www-form-urlencoded and multipart/form-data parsers.

It works best on objects created with Object.create(null). Otherwise it might conflict with variables from the prototype (e.g. hasOwnProperty).

Installation

npm install --save append-field

Usage

import appendField from 'append-field'

const obj = Object.create(null)

appendField(obj, 'pets[0][species]', 'Dahut')
appendField(obj, 'pets[0][name]', 'Hypatia')
appendField(obj, 'pets[1][species]', 'Felis Stultus')
appendField(obj, 'pets[1][name]', 'Billie')

console.log(obj)

{ pets:
   [ { species: 'Dahut', name: 'Hypatia' },
     { species: 'Felis Stultus', name: 'Billie' } ] }

API

appendField(store, key, value)

• store (object, required)
• key (string, required)
• value (any, required)

Adds the field named key with the value value to the object store.
