Today we are going to see how we can image based on resolution. We have the most common issue of loading big images in small devices take time. So, the basic solution is to use the picture element to load a different image in different devices and resolutions.

The <picture> element will be for the art direction of responsive design.

The element contains two tags.

• <source>
• <img>

So, the browser will look for the first <source> element where the media query matches the current width, and then it will display the image. The <picture> element is required as the last child of the <picture> element.

Let me show you an example of how to display a different image in different widths.

Here is a Code example,

<picture>
    <source media="(min-width:900px)" srcset="infyom_logo_lg.jpg">
    <source media="(min-width:700px)" srcset="infyom_logo_md.jpg">
    <source media="(min-width:500px)" srcset="infyom_logo_sm.jpg">
    <img src="infyom_logo_xl.jpg" alt="Flowers" style="width:auto;">
</picture>

Basically, we set up email/username and password login in all our projects. but, sometimes we need to implement s passwordless login in the laravel application,

First of all, what is passwordless login? passwordless login is an authentication method that allows the user to log in without entering a password.

In this article, I show you how to set up passwordless login laravel step by step.

Step 1:

one great laravel package Laravel Passwordless Login provides the ability to log in without a password.

This package provides a temporary signed URL link that logs in a user, What it does not provide is a way of actually sending the link to the route to the user. This is because I don't want to make any assumptions about how you communicate with your users.

Step 2:

Open the terminal and go to the project directory and fire the following command to install

composer require grosv/laravel-passwordless-login

Step 3:

Configure the following variables in your env file

  LPL_USER_MODEL=App\User
  LPL_REMEMBER_LOGIN=false
  LPL_LOGIN_ROUTE=/magic-login
  LPL_LOGIN_ROUTE_NAME=magic-login
  LPL_LOGIN_ROUTE_EXPIRES=30
  LPL_REDIRECT_ON_LOGIN=/
  LPL_USER_GUARD=web
  LPL_USE_ONCE=false
  LPL_INVALID_SIGNATURE_MESSAGE="Expired or Invalid Link"

Step 4:

Create one function in your login controller. it looks like

use App\User;
use Grosv\LaravelPasswordlessLogin\LoginUrl;

function sendLoginLink(\Request $request)
{
    $user = User::where('email','=', $request->get('email))->first();

    $generator = new LoginUrl($user);
    $url = $generator->generate();

    //OR Use a Facade
    $url = PasswordlessLogin::forUser($user)->generate();

    $data['url'] = $generator->generate();
    $data['user'] = $user;

    Mail::to($user->email)->send(new UserLoginMail($data));

    return back();
}

Step 5:

Set following route in your web.php

Route::post('/user/login', [LoginController::class, 'sendLoginLink'])->name('userLogin');

Step 6:

Create one mailable. you can refer to a doc if not familiar. Also, fire the following command to create a mailable

php artisan make:mail UserLoginMail

Step 7: Create an Email UI as per your requirement.

Lots of developers have a question: How do I create a global gitignore file? so, In this article, I show how to set up a global git ignore.

Reviewing pull requests, I often see contributors sneakily adding editor configuration to the repository’s .gitignore file.

If everyone would commit their environment-specific .gitignore rules, we’d have a long list to maintain! My repository doesn’t care about your editor configuration.

There’s a better solution to this: a personal, global .gitignore file for all your repositories. Here’s how you can set one up. create a .gitignore file for your global rules.

You can also see the following video tutorial as well.

You need to set up your global core.excludesfile configuration file to point to this global ignore file. So, let's start step by step

Step 1:

Create a file .gitignore on your profile C:\Users{username} for example C:\Users\Shailesh

Step 2:

Now you can set a .gitignore path with a three-way. we need to tell this to get this my global git to ignore file.

First Way: Using Windows git bash

Let's open Windows git bash and fire the following command,

git config --global core.excludesFile '~/.gitignore'

Second Way: Using Windows cmd

Let's open Windows cmd and fire the following command,

git config --global core.excludesFile "%USERPROFILE%\.gitignore"

Third Way: Using Windows PowerShell

Let's open Windows PowerShell and fire the following command,

git config --global core.excludesFile "$Env:USERPROFILE\.gitignore"

So, you can easily set the .gitignore global file.

Recently, I've started working on one project where we need to set up a virtual host with HTTPS because I need to run that project with expose and Shopify in my local development machine. I've wamp 3.2.3 on my local machine.

I spent a lot of time setting it. so, I thought I should write one article and video for a step-by-step guide. So, I will show you in this article how to set up HTTPS for a local machine.

You can watch the following video tutorial or follow the article.

Step 1 - Install Wamp

Install wamp server if not installed in your local machine. you can download the latest version of the wamp server from here. wamp server is available in 32 bit and 64 bit. make sure you select the correct version of the wamp server based on your operating system (window)'s version.

Step 2 - Install OpenSSL

OpenSSL is an open-source command-line tool that is used to generate the SSL certificate and private key. OpenSSL is available in both versions 32 and 64 bit. download the latest version of OpenSSL from here.

I hope you successfully installed OpenSSL on your machine. let's take the next step

Step 3 - Create a Private key

Open your terminal as an Administrator otherwise you will get a permission denied error. Also, you can provide permission to the OpenSSL directory and run the terminal in normal mode.

Now, let go to where we installed OpenSSL

cd C:\Program Files\OpenSSL-Win64\bin

Let's create a private key which is 2048 bits encryption. fire one by one the following two commands to create it.

openssl genrsa -aes256 -out private.key 2048

openssl rsa -in private.key -out private.key

Your private.key is successfully generated here C:\Program Files\OpenSSL-Win64\bin

Step 4 - Create an SSL Certificate

Let's create a certificate using the following command,

openssl req -new -x509 -nodes -sha1 -key private.key -out certificate.crt -days 36500

You need to enter a detail that looks like

You can verify here

Step 5 - Move both Private Key and a Certificate

Open a directory D:\wamp64\bin\apache\apache2.4.46\conf (Based on where your wamp is installed) and create a key directory.

Now, move both files to the key directory.

Step 6 - Configure Your httpd.conf File

Open your D:\wamp64\bin\apache\apache2.4.46\conf\httpd.conf (the drive should be where your wamp is installed) and un-comment the following 3 lines one by one.

LoadModule ssl_module modules/mod_ssl.so
Include conf/extra/httpd-ssl.conf
LoadModule socache_shmcb_module modules/mod_socache_shmcb.so

Step 7 Configure Your httpd-ssl.conf File

Open your D:\wamp64\bin\apache\apache2.4.46\conf\extra\httpd-ssl.conf (the drive should be where your wamp is installed) and change the following lines.

DocumentRoot "${INSTALL_DIR}/www"
ServerName localhost:443
ServerAdmin admin@example.com
SSLCertificateKeyFile "${SRVROOT}/conf/key/private.key"
SSLCertificateFile "${SRVROOT}/conf/key/certificate.crt"

Make sure, these following all lines are set or not. if not, add it as well.

SSLSessionCache "shmcb:${SRVROOT}/logs/ssl_scache(512000)"
CustomLog "${SRVROOT}/logs/ssl_request.log" \
          "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

Step 8 Configure a Virtual Host

Hope you have created a virtual host. if not, create a virtual host using the virtual host manager which is provided by wamp.

Open an D:\wamp64\bin\apache\apache2.4.46\conf\extra\httpd-vhosts.conf and update your virtual host

Change the port :80 to :443

add the following lines into the VirtualHost.

SSLEngine on
SSLCertificateFile "${SRVROOT}/conf/key/certificate.crt"
SSLCertificateKeyFile "${SRVROOT}/conf/key/private.key"

Now, the code of VirtualHost looks like,

Now, we are done. Let's restart a wamp server.

If you see a green WAMP icon everything should be right. If the icon is orange there is a problem with your syntax somewhere.

Open terminal and go to the D:\wamp64\bin\apache\apache2.4.46\bin and run httpd -t in the command prompt and if there are any syntax errors they will be listed.

if fine then open https://ladumor.test on the browser

In our daily life, we are going through lots of packages, and some of us don't know how to build our own package into Laravel.

We are going to perform the core steps to create your own package in laravel. In this tutorial we are going to build a zoom package, so we will perform steps related to it.

Setup Fresh Laravel Repo

Setup fresh laravel repo, and then create directories within it.

for e.g Create infyomlabs/zoom-api directory into the root.

Now create src directory into zoom-api

Run Composer init Into src Directory

After hitting composer init it will ask for some information from you, as you can see below image I have entered some of the information. you can just hit enter if you do not want to add other information.

Add your config file (Optional)

Create a directory config into the src directory and add your config.php file there from where you can manage your env variables.

Add Service Provider

Create your service provider from where you can do lots of actions. like you can publish config/routes/ migrations files from there. Here we are publishing the zoom config file.

Add your class (Which contains all functions)

Here we have added a Zoom class which will contain all zoom functions.

Update Composer.json

Finally, Test it in your existing project

Put the following code to your main composer.json (in your project's root). and hit composer update

  "repositories": [
        {
            "type": "path",
            "url": "infyomlabs/zoom-api",
            "options": {
                "symlink": true
            }
        }
    ],
    "license": "MIT",
    "require": {
        "infyomlabs/zoom-api": "dev-develop"
    },

Today we are going to see how we can generate a data table with one of the most popular a stisla theme.

We can actually do that in minutes with the package that we Recently developed called stisla-templates .

Our team made a great effort into this package and developed it with a new feature. This template package has Jquery Datatable support. So, anyone can easily generate CRUD(scaffold) with a Data table.

Let's see step by step, how we can do that.

You can watch the following video tutorial or follow the article.

Install Packages

Follow the installation steps given in our official documentation of Laravel InfyOm generator and stisla-templates if not installed.

Now, you have to perform the following steps.

composer require yajra/laravel-datatables-oracle:"~9.0"

This package handles the query and frontend stuff.

Register provider and facade on your config/app.php file.

Now clear your cache and regenerate it using the following command,

php artisan config:cache

We are done with installation and configuration.

Use Generate Scaffold with Datatable

Now I am going to add an option jqueryDT, at last, to use JQuery Datatables while generating scaffolds. the command looks like

php artisan infyom:scaffold Post --jqueryDT

Enter all required inputs and generate a scaffold of Post.

All views are created inside the posts directory in the resource. Also, the post.js file is created inside the js directory in assets that are located inside the resource.

Fire the following command for compile and publish the post.js

npm run dev

Now, the data table is ready for use. you can watch the video tutorial here.

While developing complex applications, sometimes we have to validate fields and data in a totally customized way, at that time you can use laravel's custom validations rules functionality.

In this tutorial, we are going to create our own custom validation rule to compare UUID. In our case, I have to check the UUID which is actually a binary string, whether it exists on DB or not.

Laravel doesn't provide any rule to compare that binary UUID string, so we will create our own validation rule.

So let's create our custom validation rule::

Generate Custom Validation Class

So here we have created a new class named UuidExists into App\Rules

namespace App\Rules;
use Illuminate\Contracts\Validation\Rule;
use Ramsey\Uuid\Uuid;
class UuidExists implements Rule
{

    protected $table;
    protected $column;

    public function __construct($table, $column)
    {
        $this->table = $table;
        $this->column = $column;
    }
    public function passes($attribute, $value)
    {
        $value = Uuid::fromString(strtolower($value))->getBytes();
        return \DB::table($this->table)->where($this->column, $value)->exists();
    }
    public function message()
    {
        return 'The validation error message.';
    }
}

Add Rule to AppServiceProvider

Add your rule to AppServiceProvider.php into boot() method. here I have to give the name uuid_exists to my custom rule. you can give your own name whatever you want.

\Validator::extend('uuid_exists', function ($attribute, $value, $parameters, $validator) {
    list($table, $column) = $parameters;
    return (new UuidExists($table, $column))->passes($attribute, $value);
});

How to use custom rules?

You can use your custom rule as follows. Here we have using the required and uuid_exists rule, where we are passing attributes and values to our custom rule, which will be used to passes($attribute, $value) function.

'tenant_id' => ['required', 'uuid_exists:tenant_id,uuid']

Keep connected to us for more interesting posts about Laravel.

In the last blog we have discussed two perspectives namely Financial Perspective and Internal Process perspective out of four perspectives of BSC. Let's look at the remaining two perspectives.

Customer Perspective

We all know that the 'Customer is the king of the market' and that's why we need to ensure that we have a satisfied customer group in the market.

Each organization serves a specific need in the market and this is done with a target group in mind. There are many points to focus like the Quality, Price, Service, and acceptable Margins on the products and/or services.

The organization always tries to meet customers' expectations in the market and that's why any organization needs to keep its eyes on the market and be ready to adapt to changes quickly.

The existence of alternatives( competitors ) has a huge influence on customers' expectations and we need to focus on overall market trends to build satisfied buyers in the market.

This perspective answer the question: "How attractive should we appear to our customers?"

In short, we need to focus on three points-

1. Target Group in Market
2. The expectation of the Customers
3. Our Competitors

After focusing on these points definitely, we will be able to lure maximum potential customers in the market.

Learning and Growth Perspective

In today's competitive era, if we are not ready/capable of learning something new then it's next to impossible to survive in the market as 'nothing is constant only the change is constant.

Here knowledge is not important but advancing knowledge plays a vital role.

The organization's learning ability and innovation indicate whether an organization is capable of continuous improvement and growth in a dynamic environment or not. The dynamic environment is subject to change on a daily basis due to new laws, economical changes, technological changes, or even increasing competition.

This perspective answer the questions:

"How can we sustain our ability to achieve our chosen strategy ?"
