then-busboy

then-busboy

Promise-based wrapper around Busboy, inspired by async-busboy

Installation

Use can install then-busboy from npm:

npm install then-busboy --save

Or with yarn

yarn add then-busboy
yarn

Usage

busboy(request[, options]) -> Promise

• http.IncomingMessage request - HTTP request object
• object options
  • boolean split - If set as true, the data object will be split into two other objects: fields and files.
  • more information about busboy options here.

Just import then-busboy and pass request object as first argument.

For example:

var busboy = require("then-busboy");
var createServer = require("http").createServer;

function callback(req, res) {
  if (req.method === "GET") {
    res.statusCode = 404
    return res.end("Not Found");
  }

  if (req.method !== "POST") {
    res.statusCode = 405;
    return res.end("Method Not Allowed");
  }

  // Get result from then-busboy
  function onFulfilled(data) {
    res.writeHead("Content-Type", "application/json");
    res.end(JSON.stringify(data));
  }

  // Handle errors
  function onRejected(err) {
    res.statusCode = err.status || 500;
    res.end(String(err));
  }

  // Call `then-busboy` with `req`
  busboy(req).then(onFulfilled, onRejected);
}

createServer(callback)
  .listen(2319, () => console.log("Server started on http://localhost:2319"));

then-busboy always returns a Promise, so you can use it with asynchronous function syntax:

// Some of your awesome code with async workflow...
var data = await busboy(req);

And the same code, but with split: true option:

var {fields, files} = await busboy(req, {split: true});
