Is It Up or Not?
Simple app to monitor a status of environments. Allows to set them "Up" and "Down" and to provide a reason why it's down.
Deployment
App can be deployed simply to Heroku. Run git push heroku master and then heroku run rake db:migrate && heroku run rake db:seed.
After that, you'll need to set environment variables. Right now, SECRET_KEY_BASE is needed:
$ heroku config:set SECRET_KEY_BASE=YOUR_VERY_LONG_RANDOM_HEX_SECRET
Development
Pre-requisites
For local tests, please change the ruby version in Gemfile to whatever your system uses, or install respective version using tool like rbenv.
Environment
In root folder, run:
$ bundle install --without production && bundle exec rake db:migrate
# If you want to pre-load the data:
$ bundle exec rake db:seed
In frontend_app folder:
$ npm install
Development workflow
This app is split into two parts:
- Backend, which is a Rails API providing flags.
- Frontend JS app which uses AngularJS and Lineman for development workflow. Frontend app is stored in frontend_app folder.
To run the app, run two processes:
# In root folder:
$ bundle exec rails server
# In frontend_app folder:
$ lineman grunt pages && lineman run
This will run a backend server on port 3000 and JS server on port 8000. Application can be accessed using localhost:8000. JS server proxies all API requests to port 3000, preventing CORS problems.
Ready for production
Once happy with your changes, you need some work to prepare all CSS/JS files ready for production. To do this:
# In frontend_app folder:
$ lineman build
# In root folder:
$ bundle exec rake assets:precompile
This compiles minified JS and CSS files. The latter puts this in Rails assets folder. Thanks to the extra step, there's no need for NodeJS environment on Heroku.
Known problems
Sometimes lineman stops working complaining about bower:install step failing. Running bower update seems to resolve the issue. Credit to @petems.
lineman grunt pages needs to be ran everytime the generated html gets deleted. I don't know the reason why it's not generated, but this way it works as expected.
