Ultra is a web framework that leans hard into your browser’s native features. Embrace the future of ES Modules, Import Maps, and Web Streams. All while supporting some of the non-standards that many normal people love for some reason (JSX and TypeScript).

It’s driven by the following hot-takes:

• ESM is non-negotiable in {currentYear}
• SSR is non-negotiable in {currentYear}
• Bundling is an anti-pattern in {currentYear}
• Data can be requested anywhere, and is accessible on the server, always
• Lazy routing with dynamic imports trumps FS routing
• Less magic in tooling and frameworks is a good thing
• Simplify your workflow and tech stack at all costs - life is too short
• Streams are neat

v0.7.0

This is a near full rewrite of Ultra. It includes:

• Removal of Oak, in favour of std/http library. This makes it heaps easier to deploy to multiple targets
• Addition of preloadmodule link header attributes for core and application level assets
• Main app entry point added to importMap
• Deno Deploy support via GitHub Actions
• Fly/Docker support
• Example projects moved into their own repo for easier hacking

v1.0.0 Roadmap (+ Beyond)

As we await the official release of React 18, here some things we are interested in for the future of Ultra:

• Deno vendor: Serve remote packages locally
• Vercel support
• React 18 ESM support
• Native import maps: Browser support for import maps is still a bit sketchy. Instead of using import map polyfills, Ultra inlines your imports directly into the served ES modules.
• Simpler alternatives to esm.sh
• Dynamic import support on Deno Deploy
• Native CSS modules
• A custom request context hook
• Meaningful Puppeteer tests

Thank you for going on this journey with us.
