Scanning barcode without physical barcode scanner!

Generate Barcode

Let's generate barcode first. To do that, add milon/barcode package first.

composer require milon/barcode

Suppose, we have products ID like P-10001, P-10002, P-10003 and so on. To generate custom database ID like this, you can use Laravel ID generator.

Controller code

public function barcode(Request $request){
  $product = Product::find($request->get('id'));
  return view('barcode',compact('product'));
}

View code

<div class="barcode">
    <p>{{$product->name}}</p>
    <p>Price: {{$product->sale_price}}</p>
    {!! DNS1D::getBarcodeHTML($product->id, "C128",1.4,22) !!}
    <p>{{$product->id}}</p>
</div>

Note: Style the barcode css class according to your need. Please keep in mind most commonly used barcode sticker for printing barcode is 100x150mm

Scanning barcode without physical scanner!

After generating barcode basically we need a real physical barcode scanner for scanning barcode from product sticker and feed the code into our application but there is a free solution where you don't need physical barcode reader!

Barcode Client Server is a free barcode reader android application which can read barcode and send it to your PC. It's free and there is no scan limit!

How the Barcode Client Server works

Laravel 6/7 secret route for maintenance bypass!

Laravel Article — Fri, 01 Jan 2021 04:41:07 +0000

From Laravel 8, you can bypass maintenance mode only for you with a secret route! It's a really nice and flexible feature to bypass maintenance mode only for you and your developer when the application in maintenance mode. We can use this kind of features in our existing laravel 6, laravel 7 projects with a lightweight laravel package called haruncpi/laravel-maintenance. Let's see how we can use it our project.

Install package

composer require haruncpi/laravel-maintenance

Now replace the default maintenance middleware in app/Http/kernel.php

//\App\Http\Middleware\CheckForMaintenanceMode::class,
\Haruncpi\LaravelMaintenance\Middleware\MaintenanceMode::class,

Installation finished!

Enable maintenance mode with secret route

php artisan down --secret="mysecretkey"

Maintenance bypass

https://example.com/mysecretkey

Here mysecretkey is a secret key which we defined earlier in artisan down command. Make sure you make it complex for better security.

After visiting the secret route, you will get the application live only in your side and the rest of the world gets it in maintenance mode.
