Is the way we do things today the “one true way”? Will we be doing things this way in 2025? 2050? 2100? Does knowledge always progress from good to better? Are we stuck in a local maxima?

WebNative 🚀 Natural Consequences • Server-focus • Must learn more of stack • Single source of truth • DevOps, Docker, k8s • Latency assumption • FE deeply concerned with data sync

WebNative 🚀 What Even is a “Server”?

Auth gatekeeper (because multi-tenant data) 2. Resource availability 3. Out-of-band compute (e.g. batch tasks)

What if we turn the web architecture Inside Out? 🔁

WebNative 🚀 Like Native… but for the Web 🧐

WebNative 🚀 New Assumptions, New Approach • 2021 != 1991 • Don’t need to rely on client/server • Browsers are super powerful • UI & data = only essential parts • Post-serverless, edge++ • New primitives (“game changers”) • Location independent data 🙌 • Browser-based encryption 💪 • Consistency models (OT, CRDTs, RAFT) 🤝 • i.e. State transfer -> state synchronization • New features naturally fall out of the architecture • Recognize that we’re increasingly connected/networked ffi • Local-first means network e cient (in the normal case)

WebNative 🚀 Bootstrapping from Browsers APIs • WebCrypto API • Web Workers • Service Workers • IndexedDB • PWA & Web App Manifest

If React is “just the view layer”, then WebNative is “just the data layer” It turns out the data layer touches lots of other things

WebNative 🚀 Painting a Picture 🖼 • Go from zero to production on a plane ✈ • Move data to compute and vice versa 🔄 • Publish updates from inside the browser 🚀 • Code is data = self modifying apps 🐣 • Anyone can be a service provider (lower bar to entry) 💁💁 • Including adversarial cooperation
