Minimal dependency http(s) library for node & modern browsers with:

Browser support: IE9+, with browserify/webpack Node support: v4.4+

Callback API

const request = require('honeybee')
let cancel = request({url}, function (err, res) {
  if (err) console.warn(err.statusCode, err.stack)
  else console.log(res)
})

// Immediately abort the XHR or the node http request
// The callback will not be invoked
cancel()

Native Promises

import {withPromise as request} from 'honeybee'
request({url})
  .then(res => console.log(res))
  .catch(err => console.warn(err.statusCode, err.stack))

Bound Promise

const Promise = require('bluebird')
const request = require('honeybee').withBindings(Promise)
request({url})
  .then(res => console.log(res))
  .catch(err => console.warn(err.statusCode, err.stack))
  .cancel()

Bound Defaults

// or withBindings(Promise, defaults)
const request = require('honeybee').withBindings({
  low: 500,
  high: 2000,
  total: 3,
  parseError: parseMyErrorFormat
})
request({url})

Common options

  • {string} opt.url
  • {string} opt.method GET, PUT, PATCH, POST, DELETE
  • {object} opt.headers e.g. Content-Type, Request-Id
  • {object} opt.body Will be processed by opt.serialize
  • {object} opt.query Will be serialized as the url query string
  • {number} opt.low (default: 200) Initial retry delay in milliseconds
  • {number} opt.high (default: 1000) Maximum retry delay between attempts
  • {number} opt.total (default: 5) Number of connection attempts before giving up
  • {function|string} opt.serialize(req) Should convert req.body to a string or Buffer for transport and set req.headers['content-type'] as appropriate
    • "json" => "application/json" (default)
    • "form" => "application/x-www-form-urlencoded"
    • "noop"
  • {function|string} opt.parseResponse(req, res) => Error|any res.body is a string (browser) or a Buffer (node). Called with 2xx response codes
    • "json" => Object (default)
    • "raw" => Buffer (node) or string (browser)
  • {function|string} opt.parseError(req, res) => Error called with non-2xx response codes
    • "json"
    • "text"

Browser-only options

  • {bool} opt.withCredentials Enable cross-origin cookies
  • {function} opt.onProgress(percent) 0-50: upload, 50-100: download

Node-only options

AuthorizationAgent

class AuthorizationAgent {
  /**
   * Called (once) in the event of a 401 statusCode
   * Use this to fetch a new access token for .toHeader()
   * Supports both the node-callback style as well as a Promise
   * @function refresh(opt, done)
   * @param {object} req Current request options, including headers
   * @param {function} done(err)
   * @return {function|Promise} abort()
   */

  /**
   * @function toHeader()
   * @return {string|null} The "Authorization" header
   * @example => "Bearer 718b3f..."
   */
}

Examples

import request, {Error as RequestError, parseJSON} from 'honeybee'

// Get a Google OAuth2 access token
request({
  method: 'POST',
  uri: 'https://www.googleapis.com/oauth2/v3/token',
  // Encode the request as
  serialize: 'form',
  body: {
    refresh_token: refreshToken,
    client_id: CLIENT_ID,
    client_secret: CLIENT_SECRET,
    grant_type: 'refresh_token'
  },
  parseError: function parseGoogError(req, res) {
    // Every API is different so we need to to some extra work
    // to get a useful Error out of the response
    var payload = parseJSON(res.body)
    var message  = payload && payload.error ? payload.error.message
      ? payload.error.message
      : payload.error
      : 'invalid JSON response'
    return new RequestError(res.statusCode, message, res.constructor)
  }
}, function (err, creds) {
  // The response is JSON encoded and may be handled by the default parser
  if (err) console.warn(err.stack)
  else console.log('Authorization: Bearer ' + creds.access_token)
})

// Custom serializer & response parser
request({
  method: 'POST',
  url: 'http://localhost',
  body: {foo: 1, bar: 2},
  headers: {
    'content-type': 'text/plain;charset=utf-8',
    'accept': 'text/plain;charset=utf-8'
  },
  serialize: (req) => { req.body }
  parseResponse: (res) => res.body,
  parseError: (res) => new RequestError(res.statusCode, res.body)
})

Standalone module

Create a standalone UMD bundle (which exports to window.honeybee as a last resort):

$ browserify -s honeybee . | uglifyjs -cm >honeybee-$(git describe --abbrev=0 --match 'v[0-9]*' --tags).min.js
