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 🙏

AWS CodeBuild NPM

Overview

Barchart offers streaming market data for a wide range of asset classes which trade on exchanges around the world. Review our market data catalog for details.

This SDK enables your applications to consume real-time market data, as follows:

  • A WebSocket connection is established between your application and Barchart's quote servers, then
  • Your application requests market data for one or more symbols, then
  • Your application receives a market data stream for subscribed symbols.

Openfeed

This library receives market data using a proprietary protocol called DDF. For new development, Barchart has switched to an open-source protocol called Openfeed to transfer market data. Consequently, this library will be marked as deprecated in the near future. You can access new SDK libraries for Openfeed here.

Documentation

Complete documentation for this SDK can be accessed here:

Demos

Working demos are available for web browser and Node.js environments. Please refer to the documentation.

Package Managers

This library has been published to NPM as @barchart/marketdata-api-js. Install as follows:

Build

Source code is written in ES2018. Consequently, transpilation is recommended for use in web browsers.
