Hey HN. We’re Jay and Vadim from Highlight.io (https://highlight.io). We’re building an open source [1] monitoring platform for web applications. Today we’re excited to be sharing a performance tool we’ve been working on, which helps you inspect the latency of code execution from the client to the server. As engineers at past startups, we often had to debug slow queries, poor load times, inconsistent errors, etc... While tools like Jaegar [2] helped us inspect server-side performance, we had no way to tie user events to the traces we were inspecting. In other words, although we had…

Here's a project I've been working on for a little while now. Ripl is a JS library that provides a unified API for rendering shapes on both canvas and SVG interchangeably. Over the years I've used D3 extensively to create data visualisations so I figured I'd have a go at making my own version with a slightly more modern API and stricter TypeScript support.

Two clip-paths, over the navigation: - The first clip-path is a circle (top-left corner) - The second clip-path is a polygon, that acts like a ray (hardcoded, can be improved) The original work by Iventions Events https://iventions.com/ uses JavaScript, but I found CSS-only approach more fun Here's a demo and the codebase: https://github.com/Momciloo/fun-with-clip-path
