Clone this repo to the Pi 41 | 2. Install node dependencies: ```npm install``` 42 | 3. Set up config file (see below) 43 | 44 | - [Install PM2](http://arroyocode.com/raspberry-pi-nodejs-web-server-with-pm2/) and [fix permissions](https://github.com/Unitech/pm2/issues/1654) 45 | 46 | ## Node app setup 47 | 48 | The file `config.sample.js` should be copied and renamed to `config.js` 49 | 50 | There are a few options to set: 51 | 52 | - `planeData`: Change this to the demo json file to use test data 53 | - `debug`: Output debug statements to both node and chrome console 54 | - `port`: The port to use 55 | - `position`: Your current lat/lon position 56 | - `screen`: The width and height of the display screen, for image resizing 57 | - `maxAge`: How long to store cached images and data 58 | - `timeout`: How frequently to update the screen 59 | - `launch`: The application to launch (and flags to use) on startup 60 | - `googleCseId`: The Google custom search engine ID 61 | - `googleApiKey`: The Google custom search API key 62 | 63 | You should now be able to start the application directly with `node index.js` or via `pm2` to have it automatically restart when the Pi powers up 64 | 65 | ## Placeholder images 66 | 67 | The app uses a collection of placeholder images (selected at random) if no plane is found. These are located in the directory `client/images/placeholder/` and can be replaced with others. 68 | 69 | ## More information and inspiration 70 | 71 | - [ourairports.com](http://ourairports.com/)
