multipartish

Dead simple way of producing multipart/* data. Works in browser, node, or anywhere else (hopefully), because it's super simple.

Installation

npm install multipartish --save

Example

Hello world

var MultiPartish = require('multipartish')

console.log(new MultiPartish().header("Content-Type", "text/plain").part("hello world").get())

This example shows how to upload file to Google drive

// prepare data
var MultiPartish = require('multipartish')
var name = "My File"
var body = "text\n"

var m = new MultiPartish()
m.header("Content-Type", "application/json; charset=UTF-8")
m.part(JSON.stringify(name: name))
m.header("Content-Type", "text/plain")
m.part(body)

var body_data = m.get()
var contentType = m.contentType()

// upload
gapi.client.request({
   'path': 'https://www.googleapis.com/upload/drive/v3/files',
   'method': 'POST',
   'params': {'uploadType': 'multipart'},
   'headers': { 'Content-Type': contentType },
   'body': body_data
})

Usage

Constructor

Constructor accepts a single object as parameter, encapsulating the optional arguments. Only one key is currently defined:

• boundary: set boundary value, use is discouraged, but it makes writing unit tests possible

Examples:

   var MultiPartish = require('multipartish')

   var a = new MultiPartish()
   var b = new MultiPartish({boundary: 'my-boundary'})

Methods

get()

Returns the complete multipart message. Most important method! Returns this.

part(body)

Adds a part. Second most important method! Returns this.

header(value)

Specifies a header for following part, for example .header("Content-Type: text/plain")

header(name, value)

Specifies a header for following part, for example .header('Content-Type', 'text/plain')

Equavalent to:

header(name + ": " + value)

contentType()

Returns multipart/mixed; boundary=XXX.

contentType(something)

Returns multipart/something; boundary=XXX. According to RFC you can set something to: mixed, alternative, digest or parallel.

Public properties

boundary

Boundary of multipart message. Consider this property read-only, if you feel you want to set this property, you should use the contructor argument instead.
