I am using a laravel library called `simple-qr-code` in my previous project. It is pretty easy to use and configurable and I would like to share with you today.

Firstly download the package via composer

composer require simplesoftwareio/simple-qrcode "~4"

That is all for the configuration. And you can now generate in controller like this.

use SimpleSoftwareIO\QrCode\Facades\QrCode;

QrCode::generate('Make me into a QrCode!');

This will make a QrCode that says “Make me into a QrCode!”

If you want to generate directly on the view, it is fine too.

{!! QrCode::size(300)->generate('generate Qr code'); !!}

If we want to generate a URL after reading the Qr code, we just have to pass a url string in generate function like this.

{!! QrCode::size(300)->generate('www.google.com'); !!}

You can vary the Qr code designs as well. You can see more detail here. Make sure to use when you have to deal with qr code as it is pretty easy to use.

Today, I would like to highlight a laravel package that will hep you to speed up your laravel website.

It is very important for every website to quick load that means your website should load in few seconds like 4 or 5. We are always fetching issues about page speed like how to increase website speed in laravel, how to reduce loading time of website in laravel, is it possible speed up php execution time of my website, how to optimize php laravel script to increase speed, how to speed up web browsing in laravel. So basically you have several question regarding to improve your website performance.

I found “laravel-page-speed” composer package for 35%+ optimization of laravel website. laravel-page-speed package will minify HTML output and it can be optimization your web page. laravel-page-speed package will delete unused attributes in HTML tags, delete unused quotes in HTML tags, delete unused prefixes from URLs, delete unused whitespace in HTML, delete HTML comments. Also there are several feature. They also minify css and minify js files.

Just grab the package via composer.

 composer require renatomarinho/laravel-page-speed

Publish the configuration file

php artisan vendor:publish --provider="RenatoMarinho\LaravelPageSpeed\ServiceProvider"

And then register it in Kernel file

//app/Http/Kernel.php

protected $middleware = [
    ...
    \RenatoMarinho\LaravelPageSpeed\Middleware\InlineCss::class,
    \RenatoMarinho\LaravelPageSpeed\Middleware\ElideAttributes::class,
    \RenatoMarinho\LaravelPageSpeed\Middleware\InsertDNSPrefetch::class,
    \RenatoMarinho\LaravelPageSpeed\Middleware\RemoveComments::class,
    //\RenatoMarinho\LaravelPageSpeed\Middleware\TrimUrls::class, 
    //\RenatoMarinho\LaravelPageSpeed\Middleware\RemoveQuotes::class,
    \RenatoMarinho\LaravelPageSpeed\Middleware\CollapseWhitespace::class, // Note: This middleware invokes "RemoveComments::class" before it runs.
    \RenatoMarinho\LaravelPageSpeed\Middleware\DeferJavascript::class,
]

And you are good to go.

There are several useful filtering methods that will help you to speed up your website like `RemoveComments, CollapseWhitespace, RemoveQuotes` etc.

You can see more detail in their documentation.
