A template for starting a new, minimalistic, full-stack Fulcro application. 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.
TIP: For an even simpler template with an in-browser backend, see minimalist-fulcro-template-backendless.
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 separately you will start a HTTP server from the REPL to serve the application and process Pathom requests.
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, it is best to start a client build and REPL from the editor - run Jack-in, selecting shadow-cljs then the :main build.
Now start the server: load com.example.server.main into the Shadow REPL - this will also evaluate the (defonce stop-fn (atom start)) line, starting the server.
NOTE: Now if you ever change Pathom resolvers or something, run the restart code in the (comment ...) in the main ns.
Finally, navigate to http://localhost:8008. Note: You can switch to the browser REPL by evaluating (shadow/repl :main) in the REPL. (Calva does the latter for you).
You can also compile the sources into a directory via
npx shadow-cljs release main
# or: bb build
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.
