Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Live order board

Live order board is Javascript/ typescript utility library that provides helper functions to place, cancel crypto orders. Also, you can get your all orders summary.

Live order board example.

Install

npm i live-order-board-crypto-inc

Place order

You can send order request to BUY or SELL crypto. E.g.

{
    userId: 'user 1',
    coinType: 'Bitcoin',
    orderQuantity: 100,
    pricePerCoin: '£40',
    orderType: 'Buy',
}

Orders summary

You can view top 10 orders in summary. Orders summary is organised using following assumptions:

  1. Buy orders are organised in DESC order of pricePerCoin.
  2. Sell orders are organised in ASC order of pricePerCoin.
  3. Orders of same pricePerCoin and coinType are merged using orderQuantity for both buy & sell orders.

**NOTE: In requirement document it has been mentioned to merge orders using pricePerCoin. But, I've considered merging them using both pricePerCoin & coinType. This can be change by making simple change in createOrdersSummary function.

Usage

Place Order

import { placeOrder } from 'live-order-board-crypto-inc';

const orderId = placeOrder({
  userId: 'user 1',
  coinType: 'Bitcoin',
  orderQuantity: 100,
  pricePerCoin: '£40',
  orderType: 'Buy',
});

Cancel Order

import { cancelOrder } from 'live-order-board-crypto-inc';

cancelOrder('orderId');

Orders Summary

import { getOrdersSummary } from 'live-order-board-crypto-inc';

getOrdersSummary(count);

"count" is optional. Default order summary count is 10.
