A template for starting a new, frontend-only Fulcro application with in-browser Pathom. Intended for playing with and learning Fulcro, not for production apps, and therefore simpler than the official fulcro-template. It is a good starting point for your learning projects that is hopefully simple enough for you to understand.

For a template that has an actual backend, see minimalist-fulcro-template.

Download or clone this repository to your computer and start hacking away.

You will run shadow-cljs, which will watch, compile, and update the sources and also run a HTTP server to serve the application.

Prerequisites: same as shadow-cljs'.

First, install frontend dependencies via npm, yarn, or similar:

npm install # or yarn install # reportedly yarn < v3

then start the application either via

npx shadow-cljs watch main

or, if you have Babashka installed, via

bb run

NOTE: For Calva, do instead start the REPL from the editor - run Jack-in, selecting shadow-cljs then the :main build. Remember to load the page in the browser, see below.

Finally, navigate to http://localhost:8000 and, after that, connect to the shadow-cljs nREPL at port 9001* and switch to the browser REPL by evaluating (shadow/repl :main) (Calva does the latter for you).

You can also compile the sources into a directory via

npx shadow-cljs release main
# or: bb build

and then serve the whole website using a HTTP server, e.g.:

cd resources/public/
python3 -m http.server 8000

No thought was given to security, performance, monitoring, error tracking and other important production concerns. It also bakes in fulcro-troubleshooting, which you do not want unnecessarily increasing your bundle size in production settings. So if you want to use the template as a starting point for a production application, you will need to add those yourself.

• Can we display an error in the UI when we remove the i-fail resolver from Pathom? Currently it returns ::p/errors ::p/not-found, which Fulcro ignores
