Air Now air quality reports for LaMetric using the Air Now API. Add it to your LaMetric at http://apps.lametric.com/apps/air_quality_now/439
My wife is obsessed with the air quality reports, i tried to put this together a while back but LaMetric had not yet added config params to their UIs and the geo-ip thing seemed to tiring to attempt.
I wanted to do a Travis-CI continuous deployment to heroku deal for this, and it seemed like node.js with express was the easiest way to do this, so that's what i did.
Once i decided on node & express i had been meaning to try out gulp cause i loved SBT so much, so found https://github.com/petecoop/generator-express to build a nice gulp based project, especially since it offered easy CoffeeScript support and i had been hubot'ing as of late.
No idea what all these templating engines are, Jade looked like a lot, i've used mustache and handlebars so wanted to try something new to compare. Swig looked a lot like handlebars. Marko seemed interesting with it's "concise" syntax so went with that.
Installed mocha npm install -g mocha
Installed gulp npm install -g gulp
Found the node.js plugin for intellij...but not sure that's what i want.
Tried running gulp
/lametric-air-now/node_modules/coffee-script/lib/coffee-script/coffee-script.js:234
throw helpers.updateSyntaxError(err, stripped, filename);
^
/lametric-air-now/app/controllers/home.coffee:9:1: error: unexpected indentation
indexTemplate.render
^^^^
Mucked with that quite a bit to get it to compile and show some stuff
started reading https://docs.travis-ci.com/user/languages/javascript-with-nodejs and setup a .travis.yml, but i don't have any tests and don't even know what those would look like...
switched over to heroku docs at https://devcenter.heroku.com/articles/getting-started-with-nodejs#introduction
Downloaded the tool belt and created a new app..but it failed
stumbled upon this https://devcenter.heroku.com/articles/github-integration will need to come back to that
pretty sure i failed cause of port. Need to have a heroku mode.
that wasn't it, heroku logs output

found this http://stackoverflow.com/questions/6356267/can-i-run-coffeescript-in-heroku which didn't directly answer my question, but made me just move coffee to my dependnecies out of devDependencies and that got it kinda working.
The next problem was port, and i had to modify the config.coffee to have a heroku envvironment config and switch port logic to port: process.env.PORT || 3000. i fond that port via this answer http://stackoverflow.com/a/18790034/442773 which let me know PORT was an env variable. finally i had to run heroku config:set NODE_ENV=heroku so on startup it would use my heroku config
After that it went pretty smooth. heroku has come a long way in 2 years. The have a deploy concept where they just auto deploy a commit, and can even tie to to the github status api such that they only deploy if the commit passes the status...but beyond that they kinda formalized the whoel dream of having PRs spin up new instances for testing. They fit it in to this thing called pipelines which let you promote an app from dev->stage->prod but it's way more configurable than that. The dev is by default what they call Review Apps and they really did it smart. PR's get deployed (and they can be tied to status api too) and you can run a setup file and a tear down file, they'll auto kill inactive nodes after 5 days optionally, and it can copy over config vars from a "parent" app or set them specifically or randomly: IE you can define your prod config over. Now they say that's not so good because anyone coudl write code, open a PR and output keys like mad..but it's still pretty rad. They also set some env vars to let your app know that it IS A review app so it could act tricky..maybe.
In summary: you don't deploy to heroku through travis-ci anymore, that's so last year. (YAY).
