tech-conferences/javascript-conferences ? reverse-engineered prompt

Build me a simple website that lists JavaScript conferences for frontend and Node.js developers.

It should show conferences in a clean, easy to scan way, grouped by year, with the important details like name, dates, city, country, website, call for papers link, and Twitter handle when available. Make it feel like a helpful public directory, not a big complicated app.

I also want a straightforward way to add new conferences using JSON data in the format described in the README, and please make sure it ignores workshops and user group meetups. If it helps, look up the current docs online and keep the setup simple so it’s easy to maintain later. Include a basic code of conduct and an issue template if that fits the project.
