Tradologics JavaScript SDK

This is the initial version of Tradologics' JavaScript SDK.

At the moment, it only supports a wrapper for the awesome axios library that will automatically:

• prepend the full endpoint url to your calls
• attach your token to the request headers
• add datetime to your order when in backtesting mode

Install using NPM

npm install @tradologics/tradologics

Using the library

JavaScript

const axios = require('@tradologics/tradologics');

axios.setToken('MY AWESOME TOKEN');

axios.get('/orders')
  .then((res) => {
    // do anything with response
    console.log(res.data);
  })
  .catch((err) => {
    // handle any error
    console.error(err.message);
  });

axios.post('/orders', {
  key1: 'val1',
  key2: 'val2'
  // ...
}, {
  headers: {
    'Custom-Header-Key': 'Custom-Header-Value'
    // ...
  }
})
  .then((res) => {
    // do anything with response
    console.log(res.data);
  })
  .catch((err) => {
    // handle any error
    console.error(err.message);
  });

TypeScript

import axios, { AxiosError, AxiosResponse } from '@tradologics/tradologics';

axios.setToken('MY AWESOME TOKEN');

axios.get('/orders')
  .then((res: AxiosResponse) => {
    // do anything with response
    console.log(res.data);
  })
  .catch((err: AxiosError) => {
    // handle any error
    console.error(err.message);
  });

axios.post('/orders', {
  key1: 'val1',
  key2: 'val2'
  // ...
}, {
  headers: {
    'Custom-Header-Key': 'Custom-Header-Value'
    // ...
  }
})
  .then((res: AxiosResponse) => {
    // do anything with response
    console.log(res.data);
  })
  .catch((err: AxiosError) => {
    // handle any error
    console.error(err.message);
  });

Sandbox

const { Sandbox } = require('@tradologics/tradologics/sandbox');
const { strategy } = require('./strategy');

Sandbox.setToken('MY AWESOME TOKEN');
Sandbox.price_monitor(strategy);

Running your own server

const Server = require('@tradologics/tradologics/server');
const { strategy } = require('./strategy');

Server.start(strategy, '/my-strategy', '0.0.0.0', '5000');

Using helpers

const helpers = require('@tradologics/tradologics/helpers');

helpers.sum([1, 2, 3, 4]);
helpers.mean([1, 2, 3, 4]);
helpers.median([1, 2, 3, 4]);
