Thanks David! Working on @aula_education's editor has been an unforgettable experience. I got to work with an incredible team - on a great piece of software 💜
Easily the best browser based text-editing app I have worked on 🎉
27 Sep 2021
It's @_jkrsp's last week @aula_education after working with us architecting and building our brand new content editor for 9 months
💜He has been fundamental to us being able to deliver an editor that is performant, accessible, well tested, easy to extend and feels great to use.

From the docs: “Code is increasingly written, reviewed, and transformed with machine assistance. When UI structure is more explicit, editors, compilers, and code generation tools have a better surface to work with without changing the framework semantics underneath.”

Happy to announce TSRX. Think it as the spiritual successor to JSX.
We extracted it from Ripple, and made it framework agnostic. It can compile to React, Ripple and Solid, other frameworks to come soon.
It's a TypeScript superset language, with a parser, compiler and a selection of plugins for editors Prettier ESlint, etc
It's early alpha but we thought people might be interested in it. 🧵
ALT export component Greeting({ name }: { name?: string }) { <div class="card"> if (name) { <p>{`Hello, ${name}`}</p> } else { <p>{'Hello, stranger'}</p> } </div> <style> .card { padding: 1rem; } </style> }

Meet weareonhire! or WAOH! an invite-only talent community, moderated by its members.
Invite-only approach slows growth intentionally, preventing typical decline in community quality. Every invite is public and traceable back to founding member, creating accountability and trust

I’ve been building XNS, an Ethereum-native name registry.
The design philosophy behind XNS is:
* Permanent ownership. Identity is not a subscription.
* Simplicity. No governance and configuration overhead.
If ENS expirations ever bothered you, this is for you.

Imagine opening your editor and finding an AI collaborator already working alongside you. Not as a plugin, but as a true writing partner, similar to how we use google docs with our colleagues.
I just wrote about how one could use Yjs rich text editors can make this reality:
• Real-time AI collaboration
• Context-aware suggestions
• Learning from your style
• Ethical considerations

I have been experimenting with building something like this, would you give it a go?

Rich text editors like Lexical are frontend-only, right? Wrong! 🚀
Just wrote a deep dive on processing Lexical content server-side with Rails workers. Think auto-save, content analysis, bulk operations, and search indexing - all without blocking your UI.
Perfect for content platforms that need backend intelligence.

Slate.js doesn't have a great plugin system, but you can add one with just a few lines of code. I wrote this article a few years ago and just updated it with:
✅ Better code examples with proper TypeScript
✅ Testing section with actual test code
✅ Actionable getting started steps
The article is now much more practical for teams actually implementing this approach.

I've open sourced Ripple!
github.com/trueadm/ripple
It's super early days, not much works and there's little to no documentation or guidance. Plus the codebase is raw, but I at least wanted to share my ideas with the community. :)

Google Docs & MS Office HTML is a mess when pasted into web apps. Here's how to convert it to clean, semantic HTML before it hits your editor:
✅ Fixes accessibility issues
✅ Works with Lexical, Slate, ProseMirror
✅ Removes proprietary tags & inline styles
✅ Handles lists, headings, quotes properly
Here's my guide with code examples: jkrsp.com/blog/make-ms-offic…

As someone who works on rich text editors on a daily basis, I really appreciate lexical-js's plugin architecture: It enables you to prioritise event listeners, making plugin-order less important: lnkd.in/ezBKmiqF

- npmjs.com/package/prosemirro…
Hoping this solves some peoples problems!
