There are three files involved in the system configuration for Track and Trace 2:

• The main backend configuration in /config/tntconfig.js
• The web client configuration in /client/index.html
• The scanner app configuration in /apps/scanner/config/config.js

The following chapter describes theese configuration files in detail.

The directory /config contains several configuration files named [site]_tntconfig.js, one for each site. To determine which one to use a symlink is created that is called tntconfig.js pointing at the chosen site configuration file.

The configuration file exports one single JSON object which is the configuration for all the server backend modules.

Configuration for the behaviour of the app synchronization.

  app: {
    syncallitems:false
  }

• syncallitems (boolean) : If set to true all items in the current store will always be synchronized to the scanner, default false

Configuration for the behaviour of the client backend.

  client: {
    modules: {
      accounts: true,
      reports:true
    }
  }

• modules (object) : A JSON object on the format [module_id]:[active] defining which optional modules are available in the web client. Currently the following modules are implemented [accounts, reports]

Database configuration.

  db: {
    connectionstring: "mongodb://localhost:27017/tnt_test",
    user: "admin",
    pass: "admin"
  }

• connectionstring (string) : The connectionstring telling the system which database to connect to
• user (string) : The username to connect to the database as
• pass (string) : The password for the given user

Error management configuration.

  errorhandling: {
    logconsole: true,
    logfile: "/tmp/tntErrorLog.log",

    email: {
      default: ["user1@domain.sample", "user2@domain.sample"]
    }
  }

• logconsole (boolean) : Log the error message to the console using console.log

The configuration for the web client is in the /client/index.html file and is simply a matter of setting the correct RESTURL identifying the backend REST Service to the global variable in the script.

  var RESTURLs = {
    DEV: "http://192.168.99.2:4912/",
    TEST: "http://192.168.126.130:4912/"
  };	
  RESTURL = RESTURLs.TEST;

There are a couple of preconfigured URLs to choose from and for future maintainability new sites will be added to the RESTURLs object.

The configurations for the scanner app is in the script file /apps/scanner/config/config.js which defines a config_presets global variable to the scanner app. Theese presets are presented to the user of the scanner at the first startup and the user will choose which configuration preset the scanner will use in the future.

  var config_presets = {
    test: {
      RESTURI: "http://192.168.126.130:4912/scn/",
      site: "TestSite",
      defaultStore: "TestStore",

      logoutAfter: 45*60*1000,
      receiptRequireManifest: true,
      syncInterval: 30*60*1000
    }
  }

  • defaultStore (String): The default store to use on first startup before store has been chosen
  • doOnlineSync (boolean): Whether to try to connect to the REST service to fetch items/packs that are scanned but not synchronized to the server. Doing this in bad WiFi situations will make the scanner slower.
  • logoutAfter (int): Number of milliseconds of inactivity that will trigger automatic logout
  • recieptRequireManifest (boolean): Whether to syncrhonize all manifests in state Validated to the scanner to show on Shipment Receipt
  • syncInterval (int): Maximum number of milliseconds to wait before forcing scanner synchronization in the background
