Building a Rich Text Editor in React Native

Rich text editing on the web is a solved problem. On mobile, it's a battlefield. At Digg, we built a rich text editor in React Native anyway. This talk covers what we built, what broke, and the one architectural decision that made everything else possible: a universal content format that every platform, from the editor to the backend to moderation, agrees on. You'll walk away with a practical framework for designing cross-platform content formats, useful well beyond rich text for any unified system.

How I Brought React Into a Preact Form Engine: A Production Bridge Pattern

How I Brought React Into a Preact Form Engine: A Production Bridge Pattern

Saman Abaasi

MTN Irancell — Staff Frontend Engineer & Squad Lead

In my work at MTN Irancell, we are building a Camunda-based workflow platform on top of bpmn-io Form-JS, a form engine that is rendered in Preact. The first time I had to bring a React component inside that Preact tree, it took me 2 weeks. I faced the famous "h is undefined" error one hundred times, two copies of React in memory, hooks failing, and re-render fights between Preact and React owning the same DOM. In this talk I will show the bridge I designed to solve all of this in production, with a live demo on stage where I mount a React component inside a Preact form engine in front of you.
