Using Highland in combination with node-client

Question

I'm trying to use highland in combination with the heroku-client. But internally in the heroku client it uses this, even if I try to bind to bind this, the function gives and error message where there is a refrance to this I'm not able to get it to work.

Right no the code looks like this

const Heroku = require('heroku-client');
const hl = require('highland');
var hk = new Heroku({
  token: process.env.HEROKU_API_TOKEN
});
var list = hl.wrapCallback(hk.apps().list.bind(hk));
list().toArray((a) => 'console.log(a)')

So this code snippet fails with the following error message:

...node_modules/heroku-client/lib/resourceBuilder.js:35
if (this.params.length !== pathParams.length) {
               ^

TypeError: Cannot read property 'length' of undefined

Yo! :-)

You're binding to hk and not what hk.apps() return, which is what the list function depends on (it's a member of what hk.apps() returns)

Try this:

const Heroku = require('heroku-client');
const hl = require('highland');
const hk = new Heroku({
  token: process.env.HEROKU_API_TOKEN
});
const hkApps = hk.apps();
const list = hl.wrapCallback(hkApps.list.bind(hkApps));
list().toArray((a) => 'console.log(a)')
