Shuttle Tracker    

Tracking and mapping RPI's shuttles with Go, Polymer Web Components, and MongoDB.

Check it out in action at shuttles.rpi.edu.

Setting Up

1. Install Go (https://golang.org/doc/install)
2. Ensure your $GOPATH is set correctly, and is apart of your $PATH
3. Run go get github.com/wtg/shuttletracker
4. Install govendor by running go get -u github.com/kardianos/govendor
5. Run govendor sync
6. Ensure you have NPM, Bower, and MongoDB installed.
7. Run bower install inside the Shuttle Tracker directory ($GOPATH/src/github.com/wtg/shuttletracker) to install dependencies listed in bower.json
8. Rename conf.json.sample to conf.json
9. Edit conf.json with the following:
   • DataFeed: API with tracking information from iTrak... For RPI, this is a unique API URL that we can get data from. It's currently private, and we will only share it with authorized members for now.
   • UpdateInterval: Number of seconds between each request to the data feed
   • MongoUrl: Url where MongoDB is located
   • MongoPort: Port where MongoDB is bound (default is 27017)
10. Start MongoDB, and ensure it is running, and listening on port 27017 (or whichever port you defined in MongoPort within conf.json)
11. Add data to your database. Example DBs are provided in example_database, as well as a simple import/export script to setup the database for you.
    • If using an example database, you might need to check the name of the imported database, and change MongoUrl accordingly.
12. Start the app by running go run main.go in the project root directory.
13. Visit http://localhost:8080/ to view the tracking application and http://localhost:8080/admin to view the administration panel

Configuration

Shuttle Tracker reads from a conf.json file. It can look like this:

{
  "Updater": {
    "DataFeed": "",
    "UpdateInterval": "3s"
  },
  "API": {
    "GoogleMapAPIKey": "",
    "GoogleMapMinDistance": 1,
    "CasURL": "https://cas-auth.rpi.edu/cas/",
    "Authenticate": true
  },
  "Database": {
    "MongoURL": "localhost:27017"
  },
  "Log": {
    "Level": "debug"
  },
  "Server": {
    "ListenURL": "localhost:8080"
  }
}

Environment Variables

Most keys can be overridden with environment variables. The variables names usually take the format SECTION_KEY. For example, overriding database's Mongo URL could be done with a variable named DATABASE_MONGOURL.
