Fulcro is a library for building data-driven full-stack applications for the web, native, and desktop (via electron). It uses React and is written in Clojure and Clojurescript.
1. Version Differences
Fulcro has undergone a number of face-lifts over its lifetime.
- 1.x
-
An add-on library for Om Next. Has various limitations as a result of this, and several bugs that are deep within Om Next (which was not getting updates).
- 2.0 - 2.4
-
No longer depends on Om Next. Public API is the same, except where improvements and fixes were needed.
- 2.5
-
Integrated co-located CSS for better support (e.g. localized-dom), made all server dependencies dynamic, rewrite of i18n. This version requires you to change a few i18n things if you were using it, and adds API to the DOM to make UI much more concise.
- 2.6
-
Changes for React 16+. Changes in React led to a change in the underlying rendering refresh optimizations.
- 3.0
-
This version. Rewrote the internals to simplify a lot of things, make others more extensible, all while preserving the shape of the API. It is not 100% API compatible with prior versions, and uses new namespaces. In particular, in the course of fixing some long-standing issues, subtle semantic differences were desirable/unavoidable in the transaction processing system. Most of the surface level differences are simply in the naming of things.
2. Trying it Out
The documentation for this version is in the Developer’s Guide. If you’re using Fulcro 2, you can still read the prior version of the guide.
There is also a template project which you can use as a starting point.
Finally, there is a plenty of great resources collected at the Fulcro Community site.
