REST API v2 candles always return [] !

[jwchen119]

Here's part of my code below. However, it always return empty array.

const BFX = require('bitfinex-api-node')
const bfxRest = new BFX('1234', '4321', {version: 2}).rest

var opts = {};
opts.timeframe= "1m";
opts.symbol= "tIOTUSD";
opts.section= "hist";

bfxRest.candles(opts, (err, res) => {
    if (err) console.log(err)
    console.log(res)
})

I also tried : bfxRest.candles((err, res) => {

Nothing helped, it still return []. I'm pretty sure there's some bugs, somehow I'm not able to point it out.

@jwchen119 are you using the latest version of the library (v2 beta)? If so, the constructor signature changed, it should be:

const bfxRest = new BFX({
  apiKey: '...'
  apiSecret: '...'
}).rest(2)

Yes @f3rno , I'm trying to use the candles function which only available in v2 beta. By migrating v1 to v2, there's some new problem here. I think it might be the problem of my environment? My full code is below, I'm using Heroku to build my app for testing:

'use strict';

const express = require('express');
const SocketServer = require('ws').Server;
const path = require('path');
const BFX = require('bitfinex-api-node');

const bfx = new BFX({ 
    apiKey: '1234',
    apiSecret: '4321',
})

const bfxRest = bfx.rest(2);

const PORT = process.env.PORT || 3000;
const INDEX = path.join(__dirname, 'index.html');

const server = express()
  .use((req, res) => res.sendFile(INDEX) )
  .listen(PORT, () => console.log(`Listening on ${ PORT }`));

const wss = new SocketServer({ server });

wss.on('connection', (ws) => {
  console.log('Client connected');
  ws.on('close', () => console.log('Client disconnected'));
});

var Crypto = "請稍後....";

var opts = {timeframe:"30m", symbol:"tIOTUSD", section:"hist"};

bfxRest.candles(opts, (err, res) => {
    if (err) console.log(err)
    console.log(res)
})

setInterval(() => {
    wss.clients.forEach((client) => {
    bfxRest.ticker('tIOTUSD', (err, res) => {
        if (err) console.log(err)
        console.log(res)
        Crypto = res
    })
      client.send(JSON.stringify(Crypto));
    });
}, 3000);

Build succeeded but shows this error when start up:

const rest = bfx.rest(2)
                  ^
 TypeError: bfx.rest is not a function

I know here's not the place like StackOverflow, I'm also new to node.js. If this is not related to the sourcecode please let me know and I'll close this issue, thank you.

Alright, I did make a mistake. I was using old version of "bitfinex-api-node" declare in package.json which lead to the problem. After using the version of "2.0.0-beta" all the problem solved.
