So heres my setup:

var Promise = require("bluebird");
var request = Promise.promisify(require('request'));

This works:

request('url')

It returns a promise

This doesn't:

request.post('url', {form: {type: 'artist'}})

gives me this error:

TypeError: Object function promisified(_arg0,_arg1) { ... }has no method 'post'

any ideas on how to make this work? What is the correct way to do this?

• javascript
• node.js
• request
• promise
• bluebird

When you promisify the request return you promisify only the returned function. Instead - use promisifyAll which promisifies a whole object. Since request is both you didn't get an error.

var Promise = require("bluebird");

var request = Promise.promisifyAll(require('request')); // this will work
