  33. Inventory App - Scenario •  A grocery supplies company owns

    a number of warehouses, and they need a mobile/tablet app for members of staff to lookup details of their large stock, exceeding 230,000 items •  The app needs to work offline, due to limited or no network connectivity in the warehouses or out in the field
  34. Inventory App - Scenario •  The app must be able

    to scan barcodes and quickly retrieve the associated product details, along with a photo of the product •  The app must allow the staff member to perform an inventory of items at a warehouse, capturing multiple barcodes and storing the inventory info on the device
  35. Application details •  Built using Ext JS 5.1, so that

    the grid can be leveraged •  Real dataset that contains over 230,000 grocery items and 90,000 product photos •  All data stored on the device, allowing the app to run in an offline state
  36. SecureSql •  Use of a custom SecureSql proxy enables Ext

    JS Stores to directly interact with the encrypted SQLite database •  Allows buffered stores to select pages of data, along with performing sorting and filtering •  Updates to data can be easily made through record.save Ext.define('Inventory.model.Base', { extend: 'Ext.data.Model', requires: [ 'Inventory.data.proxy.SecureSql', 'Ext.data.identifier.Uuid' ], identifier: 'uuid', proxy: { type: 'securesql', database: 'InventoryDB' } });
  37. Publishing "space": { "id": 63553, "name": "Inventory", "host": "https://api.space.sencha.com/json.rpc", "file":

    "${app.output.base}", "apiKey": "7KxGphKZwtLv+ha5w2G1Xl5FK2Ajdt4dM4uMC5b354jhm3=", "secret": "gf6Gg9Y3QaYKszJJnnnnn8N2TYnaYTaL7S2jaMFTCeLm=" } •  Applications can be deployed as an archive (Zip file) straight to the Sencha Space Management Console for simple and secure deployment to end users •  First, configure the app.json file:
  38. Publishing > sencha config -prop app.version=1.1.3 then app publish • 

    Build your Sencha app for production •  Then deploy using the “app publish” command in Sencha Cmd:
  39. Publishing •  Application runtime is then securely deployed in Sencha

    Space •  Updated app pushed to users •  Negates the need to have a web server to host the source code in an unprotected state •  Provides the capability for the app to run offline
  40. Using Invoke in Sencha Space var  success  =  function  (message)

     {        log('success  '  +  JSON.stringify(message,  null,  2));   };     var  failure  =  function  (error)  {        log('  failure  '  +  json.stringify(error,  null,  2));   };     var  send  =  function  (connection)  {        connection.send(data,  true).then(              success,              failure        );   };     Ext.space.Invoke.get('map').then(send,  failure);  
  41. Handling the Invoke Message            

       Ext.onSpaceReady(function(){                            Ext.space.Invoke.onMessage(function  (senderId,  message)  {                                  var  promise  =  new  Ext.Promise();                                  mapview.name  =  message.name;                                  mapview.setPromise(promise);                                  mapview.handleMessage(me,  message);                                    return  promise;                            });                    });   handler:  function  ()  {        try  {              mapview.getPromise().fulfill({  name:  mapview.name  });        }        catch  (err)  {              alert(err.message);        }   }  
  42. About the Map Application… •  Written with Sencha Touch 2.4.1

    •  Utilized Ext.ux.LeafletMap •  https://market.sencha.com/extensions/ext-ux-leafletmap •  Mapbox.com map tile server (could also have offline access to map tiles) •  geoJSON for building outline layer
