form-data-body v0.1.0

form-data-body

A tiny, dependency-free node module for generating a form's multipart/form-data body for a POST request.

This is meant to be a simple, no frills module for generating a string to send as the body for a POST request simulating a form submission. If you need something with more bells and whistles, check out the form-data module.

Installation

npm install --save form-data-body

Usage

const formDataBody = require('form-data-body')

// Specify form fields
const fields = {
  name: 'My test post',
  description: 'This is just a test post',
  items: ['First Item', 'Second Item'],

  // Files should be an object with the name, type, and data set to strings
  image: {
    name: 'hello.jpg',
    type: 'image/jpeg',
    data: binaryImageData
  }
}

const boundary = formDataBody.generateBoundary()
const header = {
  'Content-Type': `multipart/form-data; boundary=${boundary}`
}
const body = formDataBody(fields, boundary)
