Is FromQuery OK with this size of data?

FromQuery chunks the query into smaller batches of data

In queue section how can I send the file to email after the queue is done?!

You have to chain a queued job, please refer to Laravel documentation on how to send an email

controller: function excel(){ return (new UsersExport())->download('invoices.xlsx'); } in the Export folder UsersExport.php file `<?php namespace App\Exports; use App\Models\TEST; use Maatwebsite\Excel\Concerns\FromCollection; use Maatwebsite\Excel\Concerns\Exportable; use Maatwebsite\Excel\Concerns\FromQuery; use Maatwebsite\Excel\Concerns\WithHeadings; use Maatwebsite\Excel\Concerns\WithMapping; use Maatwebsite\Excel\Concerns\FromArray; use Illuminate\Contracts\Queue\ShouldQueue;

class UsersExport implements FromQuery, WithMapping, WithHeadings,ShouldQueue { /**

• @return \Illuminate\Support\Collection */
  use Exportable;

  public function query() { return TEST::query()->where('status_id','!=','12'); }

  public function headings(): array { return [ 'test Id', 'test Tracking Id','test Type','customer name', 'Receiver Info','Pickup','Delivery','cash','Charge','Status','cash Payment','Paid By','Request Time','Pickup Time','Delivery Time','Time Duration' ]; }

  public function map($row): array { if($row->delivery == '0' || empty($row->delivery)){ $delivery = (!empty($row->branch->name)?$row->branch->name:'Not Available'); }else{ $delivery=(!empty(\App\Models\Branch::find($row->delivery)->name)?\App\Models\Branch::find($row->delivery)->name:'Not Available'); }

  $picks =\App\Models\TestLog::where('courier_id',$row->id)->where('status_id','13')->first(); return [ $row->id, $row->tracking_id, $row->test_type->title, !empty($row->customer->name)?$row->customer->name:"Not Available", $row->receiver_name.'-- '. $row->receiver_address .'-- '.$row->receiver_phone, !empty($row->pickup->name)?$row->pickup->name:"Not Available", !empty($delivery)?$delivery:"Not Available", $row->cash, $row->pricing->price, $row->status->name, $row->cash_status, $row->paid_by, date('d-m-Y h:i A',strtotime($row->created_at)), !empty($picks->created_at)?date('d-m-Y h:i A',strtotime($picks->created_at)):"Not Available", !empty($row->delivery_date)?date('d-m-Y h:i A',strtotime($row->delivery_date)):"Not Available", $row->created_at->diffForHumans() ]; }
