Example of a custom list handler for use with FeedHenry Node.js Data Sync

sample-list-handler.js

const sync = require('fh-mbaas-api').sync
const workorders = require('lib/sql/workorders')

// Typical init code etc...

// Example of getting work orders for a specific user
sync.handleList('workorders', function(datasetId, query, metadata, done) {
  // Getting by the userId passed to the sync framework and the region they are in
  workorders.getDataForUserInRegion(query.userId, query.region, (err, specificUserWorkOrders) => {
    if (err) {
      done(err)
    } else {
      // Assuming the database driver returns an array, we need to convert into an
      // object (hash map) for sync to utilise it
      //  [{
      //    id: 12345
      //    columns: {
      //      customerId: 54321,
      //      address: 'Twin Peaks, WA',
      //      name: 'Packard Sawmill'
      //    }
      //  }]
      
      const ret = {}
      
      // Reformat using a loop, could also use specificUserWorkOrders.reduce
      specificUserWorkOrders.forEach((wo) => {
        ret[wo.id] = wo.columns;
      })
      
      // Return data is of format:
      //  {
      //    12345: {
      //      customerId: 54321,
      //      address: 'Twin Peaks, WA',
      //      name: 'Packard Sawmill'
      //    }
      //  }
      
      done(null, ret)
    }
