Dynamic websites
Render pages on the server with content from a headless CMS, a remote API or Markdown files.
Explore Jeasx
Use asynchronous JSX as an intuitive templating language
for the server-side rendered web.
Visit jeasx.dev to learn more about the framework.
The source code of all examples is on GitHub: clone it to run them on your own computer and start experimenting. Every example links to its source in the top right corner.
The examples are styled with µCSS, a lightweight and mostly classless CSS framework, so their markup stays short and easy to read.
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 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.
