Jaspr is a modern web framework for building websites in Dart with support for both client-side and server-side rendering, as well as static site generation.
Jaspr is an alternative to Flutter Web, when you want to build any kind of website with Dart.
This includes (but is not limited to):
- Static Sites.
- Server-Rendered Sites.
- Single-Page Applications.
Jaspr works by giving you the familiar look and feel of the Flutter framework, while using native web technologies, like HTML, the DOM and CSS to enable you building all kinds of websites using Dart.
This is free and open source software.
Key Features
- Familiar: Works with a similar component model to Flutter widgets.
- Powerful: Comes with server side rendering out of the box.
- Easy: Syncs component state between server and client automatically.
- Fast: Performs direct DOM updates only where needed.
- Flexible: Runs on the server, client or both with manual or automatic setup. You decide.
