ample application in Javascript on NodeJS for Wercker

This application uses the node container obtained from the Docker Hub

lone this repo and cd into the directory:

git clone https://github.com/wercker/getting-started-nodejs.git
cd getting-started-nodejs

You can run the sample app in a couple of different ways. The first is to simply launch the executable:

node app.js

Now point your browser at http://localhost:8080 to see:

{"cities":["Amsterdam","Berlin","New York","San Francisco","Tokyo"]}

The second, and more useful, way is to use the wercker dev command to launch the binary within a Docker container, using the base image defined in the box/id property at the top of the wercker.yml, like so:

wercker dev --expose-ports

The dev target inside wercker.yml uses the internal/watch step to dynamically reload the runtime container when sourcefile changes are detected, which allows you to quickly test changes without having to kill/rebuild/relaunch the container. For instance, add another city to the array on `app.js:3' like so:

var cities = {"cities":["Amsterdam","Berlin","New York","San Francisco","Tokyo","London"]}

and then refresh your browser pointing to http://localhost:8080 to see:

{"cities":["Amsterdam","Berlin","New York","San Francisco","Tokyo","London"]}}
