DB loads records from your API or sync engine into typed collections. Live queries join and filter across them and update as data changes. Optimistic edits apply at once and sync to your backend, with rollbacks handled for you.

The opportunity nowadays to hire top <1% talent is impossibly slim, and Corbin would be a steal. Don’t pass it up.
I am looking for my next career opportunity! I'm Corbin Crutchley; an engineering leader, consultant, author, and open-source maintainer. Previously as a VP of Eng, I've sped up engineering efforts for companies. My teams rework large-scale systems while building new features at the same time. You may also know of my OSS projects (@tan_stack & others) or my books (@playful_program). Roles I'm looking for: - CTO / VP of Engineering for small/medium companies - Staff+ Engineering roles, esp developer tooling - Consulting gigs Likewise, if your project is particularly challenging and / or complex, let's talk. Know of a good role for me? Book some time on my website or reach out in direct messages: corbincrutchley.com

TanStack Markdown + Highlight 1.0 🏝️ Ship only the syntax, languages, and features users need with balanced flexibility, power and speed. Small enough to ship to the client and 1 less reason for server components 🤷‍♂️ Enjoy! tanstack.com/markdown tanstack.com/highlight
