Follow deployement and operation of micro-service components from GitHub Repositories to AWS CloudFormation stacks.
This repository is in (very) early development stage.
The project use Environ to manage its configuration. You can either set configuration parameters through profiles.clj file, java property file or environment variables.
| Clojure | Provperty | Environement | Description |
|---|---|---|---|
| db-uri | db.uri | DB_URI | URI of the datomic database |
| web-port | web.port | WEB_PORT | TCP port for the web server |
| gh-auth | gh.auth | GH_AUTH | Authentication to GitHub account |
| gh-org | gh.org | GH_ORG | GitHub organisation in whitch components repositories are |
| aws-region | aws.region | AWS_REGION | AWS Region on which CloudFormation Stacks are deployed |
AWS authentication is either done through Amazonica. You can either use local .aws directory or IAM roles.
Open a terminal and type lein repl to start a Clojure REPL
(interactive prompt).
In the REPL, type
(run)
(browser-repl)The call to (run) starts the Figwheel server at port 3449, which takes care of
live reloading ClojureScript code and CSS. Figwheel's server will also act as
your app server, so requests are correctly forwarded to the http-handler you
define.
Running (browser-repl) starts the Figwheel ClojureScript REPL. Evaluating
expressions here will only work once you've loaded the page, so the browser can
connect to Figwheel.
When you see the line Successfully compiled "resources/public/app.js" in 21.36 seconds., you're ready to go. Browse to http://localhost:3449 and enjoy.
Attention: It is not needed to run lein figwheel separately. Instead we
launch Figwheel directly from the REPL
If all is well you now have a browser window saying 'Hello Chestnut',
and a REPL prompt that looks like cljs.user=>.
Open resources/public/css/style.css and change some styling of the
H1 element. Notice how it's updated instantly in the browser.
Open src/cljs/hecatoncheires/core.cljs, and change dom/h1 to
dom/h2. As soon as you save the file, your browser is updated.
In the REPL, type
(ns hecatoncheires.core)
(swap! app-state assoc :text "Interactivity FTW")
Notice again how the browser updates.
Lighttable provides a tighter integration for live coding with an inline browser-tab. Rather than evaluating cljs on the command line with the Figwheel REPL, you can evaluate code and preview pages inside Lighttable.
Steps: After running (run), open a browser tab in Lighttable. Open a cljs file
from within a project, go to the end of an s-expression and hit Cmd-ENT.
Lighttable will ask you which client to connect. Click 'Connect a client' and
select 'Browser'. Browse to http://localhost:3449
View LT's console to see a Chrome js console.
Hereafter, you can save a file and see changes or evaluate cljs code (without saving a file).
CIDER is able to start both a Clojure and a ClojureScript REPL simultaneously,
so you can interact both with the browser, and with the server. The command to
do this is M-x cider-jack-in-clojurescript.
We need to tell CIDER how to start a browser-connected Figwheel REPL though, otherwise it will use a JavaScript engine provided by the JVM, and you won't be able to interact with your running app.
Put this in your Emacs configuration (~/.emacs.d/init.el or ~/.emacs)
(setq cider-cljs-lein-repl
"(do (user/run)
(user/browser-repl))")Now M-x cider-jack-in-clojurescript (shortcut: C-c M-J, that's a capital
"J", so Meta-Shift-j), point your browser at http://localhost:3449, and
you're good to go.
To run the Clojure tests, use
lein testTo run the Clojurescript you use doo. This can run your tests against a variety of JavaScript implementations, but in the browser and "headless". For example, to test with PhantomJS, use
lein doo phantomCopyright © 2016 Sierra Wireless
