One of the best examples is the data URLs from AWS buckets. it's not a good idea to store sensitive data into a public AWS Bucket, as the URL is accessible by the people.

Of Course, you can store profile avatars and others data to the public bucket's that not contains any confidential information. so that's fine.

But when it's about confidential information like PAN CARD Details, AADHAR Card Details, Bank Informations we Must Recommend using AWS Protected Bucket.

In this tutorial, we are going to show that how we can prevent that kind of case, Or how we can integrate AWS Protected Bucket in our Laravel Application.

The following code will help you to generate a pre-signed AWS URL that will prevent our data, that URL is non-guessable and it will expire within some minutes/hours specified by us.

So let's start with some code :

$s3 = \Storage::disk(config('filesystems.s3_protected_disk'));
$client = $s3->getDriver()->getAdapter()->getClient();
$expiry = "+1 minutes";
$command = $client->getCommand('GetObject', [
  'Bucket' => \Config::get('filesystems.disks. s3_protected_disk.bucket'),
      'Key'    => 'Path to your file',
    ]);
$request = $client->createPresignedRequest($command, $expiry);
    return (string) $request->getUrl();

So here we have created an s3 instance and it's stored on the $s3 variable, we have specified the expiry time as 1 minute so the given URL for data will be expired within a minute.

Also, we have to specify the bucket name and path to our protected file to generate AWS pre-signed URL.

It will return the pre-signed URL and its looks like as the following URL.

https://pre-signed.s3.au-west-2.amazonaws.com/image.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=xxxxxxxx%2F20180210%2Feu-west-2%2Fs3%2Faws4_request&X-Amz-Date=20210210T171315Z&X-Amz-Expires=60&X-Amz-Signature=xxxxxxxx&X-Amz-SignedHeaders=host

Hope this helps.

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.

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.

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"
    },

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.

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']
