Less framework, fewer headaches
Jeasx keeps its core small: asynchronous JSX on the server, file-based routing, and little else. Everything beyond that is integrated in userland with code you own and can adapt.

Run it yourself
All examples are on GitHub. Clone the repository to run them locally. Every example links to its source in the top right corner. Change the code freely and see what happens.
Dynamic websites
Render pages on the server with content from a remote API, JSON data or Markdown with MDX.
Web applications without client-side JavaScript
Build interactive apps with plain HTML forms. The server does the work, and view transitions make page changes feel smooth.
Hypermedia with HTMX
Every Jeasx route can return an HTML fragment, so hypermedia libraries like HTMX and Fixi can update parts of a page with markup rendered on the server.
Islands of client-side JavaScript
Add islands of interactivity to server-rendered pages with the client-side library you already know.
Streaming and Server-Sent Events
Use the standards of the web platform: stream HTML with a Response or a ReadableStream or push live updates.
Images, JSON and other content types
Routes aren't limited to HTML: they can return images, SVG, JSON, XML or any other content type.
Rendering with JSX
Compose components, share request context, manage the head, control what JSX renders on the server and in the browser, and test components with unit tests.
Authentication and security
Protect routes with basic auth or sessions, sign cookies, block injected scripts and stop bots with a proof-of-work captcha.
Error handling and post-processing
Catch errors and transform the final HTML before it is sent to the browser.
