Om Tutorial Code

This is a project holding an Om (next) project that is to be used as the basis of a complete overview of the features of Om. For simplicity, the server-side component is simulated in the browser. The code you would write on the server is identical (though you will need some minor plumbing to do the actual network bits).

I try to keep it running at https://awkay.github.io/om-tutorial/, though it is really meant to be cloned locally, as the exercises have you edit the code.

What's inside?

The organization is in flux. The top-level src directory contains:

• tutorial: Devcards with a live tutorial (in progress)
• main: A demo application with simulated remote server (in progress, but working with Om master or alpha25+)
• cards : Some development/tests written in devcards

The latter two are for my internal purposes at the moment, so you can largely ignore them.

Running it

There is a clojure script in the script folder. You can run it with lein or in Cursive (Run..., Add a Clojure Local REPL, Run with Clojure Main (NOT nREPL!), parameters script/figwheel.clj) or at the command line with:

lein run -m clojure.main script/figwheel.clj

Using Emacs, just start up the repl with cider-jack-in (or connect to a running lein repl), and evaluate the contents of script/figwheel.clj in the repl. Similar steps should work find for fireplace in Vim.

Then browse to the following URL:

http://localhost:3450   Devcards-based Tutorial (start here)

Expect things to change often...this is a work in progress that may take several weeks or even months. If you'd like to contribute, I'd love the help. Ping me on Slack (@tony.kay) so we don't stomp on each other.

Some things I'd like to have (but don't have the time to get to):

• Docs in the UI section (or a subsection) that talk about more basics of (stateless) UI. E.g. more references to React docs, what the #js stuff is about and why you only do it on dom elements. Basic gotchas for beginners. Bonus points if anyone wants to hack the cljs ecosystem so that code pretty-printing can handle #js.
• CSS for anything you think is too ugly

Figwheel notes

Once the figwheel REPL is going, you can clean and rebuild with

(reset-autobuild)

after which you probably want to reload the page in your browser to clear out any cruft.
