Installation

You will need Node 4.x+ to run vddf-server properly.

• Use npm install to install all the dependencies.
• Run ./scripts/install_adaviz.sh to clone and compile adaviz.
• Run npm run dev to start vddf-server on port 5001.

Chrome Extension Development

Chrome extension is auto built when you run npm run dev. You can load the extension from build/chrome.

Important: in development mode, you will need to configure the extension to use local vddf-server. Please visit the Chrome Extension page, then click on Options link and set VDDF Server to http://localhost:5001.

Deployment

• Run npm run build to build all assets for production
• Run NODE_ENV=production npm start to start server

By default, vddf-server will use the configuration provided in config.json, you can also override the config file with CONFIG_FILE environment variable.

For production environment, you should switch storage from sqlite to mysql. You can do it by edit the database section in config.json. Below is an example for configuration with mysql:

...
  database: {
    client: 'mysql',
    connection: {
      host     : '127.0.0.1',
      user     : 'your_database_user',
      password : 'your_database_password',
      database : 'myapp_test'
    }
  }
...

For some linux distro, you may need to install libfontconfig to make phantomjs works.
