Development
Dead simple setup
Get yourself the Elm programming language:
On node 6+: npm install -g elm && npm install
Then you can just do elm-make src/Main.elm --output=elm.js and open index.html.
Nicer workflow
Use elm-live (npm install -g elm-live) and then run npm run dev.
This will open a browser tab with CSS hot reloading and page refreshing on Elm code changes.
Working on the Zendesk App
npm install will install the necessary dev tools.
npm start will run a development server, you can preview your changes on Zendesk by adding the query string: ?zat=true to the end of the Zendesk Support url.
Testing
Setup for first time Elm testers:
npm i -g elm-test
Use npm test to run the elm-test unit, fuzz, and view tests.
