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 🙏

ComPort

A simple package to use the new Serial Api available in Chrome

🔥 Notice : Serial Api is under Chrome experimental flag for Chrome 79 and expected to goes on Origins Trail on Chrome 80

Why Serial Api

Although WebUSB has been around for some years, it is mainly targeted at companies intending to developed web-based firmwares. A major downside of WebUSB is once a native driver is installed on the OS, the device will no longer be recognized by WebUSB. Unlike WebUSB, the Serial Api is intended for use as a traditional COM port (Serial port) which includes many microcontroller based devices and USB-to-Serial devices such as FTDI and Cypress chipsets. Additionally, you can still implement your own USB CDC protocol, and have the OS driver and Web driver co-exist. The Serial Api opens doors for new and exciting web-based front-ends for small and medium sized embedded projects.

Why ComPort

ComPort makes it easy for embedded developers to quickly build a modern front-end for their applications. It removes the hassle of dealing with async/await functions. This package is not intended for high-performance and high data-rate applications, but for quick and simple development. If high-performance is required then a browser based app is probably the wrong choice.

Potential use cases

all serial communication to and from embedded hardware via USB-to-Serial bridges like FTDI cables and Arduino boards.

How to enable Serial Api (Chrome 79)

Enable it in: chrome://flags/#enable-experimental-web-platform-features

Build instructions

npm i
npm run build

installation

npm i @danchitnis/comport

Examples

See here examples tested with Arduino Nano 33 BLE, but also extendable to other boards as it is simply using serial communication.
