But if you want to add another project as a library in your application. For that, you need to add that library project to your application as a module dependency.

1. Open Your Project in Android Studio.

2. You will find the two main directory name samples and others.

3. Go to Android Studio and navigate to File -> New -> Import Module -> Select the library path -> Finish.

4. Import-Module from Directory.

5. Then right-click on the App directory -> Open Module Settings -> Dependencies -> Click on + button inside Declared Dependencies -> Module Dependency -> Select your library -> Ok.

Another way to add Module Dependency

• Open build.gradle Of the main module

dependencies {

implementation project(":sample")

}

There can be a situation when we need to modify the library code according to our requirement then in that case we can follow this method.

Generally, we are using a Laravel One Signal package for push notification. if you are planning to use one signal in the mobile application then this package right for you.

Recently, I add a new feature UserDevice. let me explain why I added support for user Device APIs.

We need to create an API to register a device because One Signal sends a push notification using os player id. so, we need to store os_player_id in the backend from the mobile application. So, need to create an API for it.

Now. you can save your time using this package. you can Generate APIs using one artisan command,

php artisan one-signal.userDevice:publish

This command generates the following files,

• UserDeviceAPIController
• UserDeviceAPIRepository
• UserDevice (model)
• Migration So, everything is ready in minutes and delivered an API on the spot.

Also, do not forget to add the following routes to the api.php file.

use App\Http\Controllers\API\UserDeviceAPIController;

Route::post('user-device/register', [UserDeviceAPIController::class, 'registerDevice']);
Route::get('user-device/{playerId}/update-status', [UserDeviceAPIController::class, 'updateNotificationStatus']);

We have recently developed a site into the gatsby. Basically, the contact us feature is common on all websites. and we are implementing Mailchimp because it's a very popular platform in the email market. So, I will show you how to set up a Mailchimp on the Gatsby site.

Using gatsby-source-mailchimp

Use your Mailchimp API key to download your campaigns into Gatsby’s GraphQL data layer! Install the package by running the following command: npm i gatsby-source-mailchimp --save. How to configure Once the installation is complete, you can now add this plugin to your gatsby-config.js, like so: Configure mailchimp Key and add this {resolve: gatsby-source-mailchimp} into the plugins array. code looks like

module.exports = {
  // ...
  plugins: [
    {
      resolve: 'gatsby-source-mailchimp',
      options: {
        // Avoid including your key directly in your file.
        // Instead, opt for adding them to .env files for extra
        // security ;)
        key: 'asd712jdas90122jdas90122jkadsd1-usXX',
        rootURL: 'https://usXX.api.mailchimp.com/3.0',
      },
    },
  ],
  // ...
}

This plugin was made out of a specific necessity, so it doesn't cover all of Mailchimp’s data sources, focusing only on campaigns.

This plugin provides few options. you can refer here

Using .env variables to hide your key

If you don’t want to attach your API key to the repo, you can easily store it in .env files by doing the following:

// In your .env file
MAILCHIMP_KEY = 'asd712jdas90122jdas90122jkadsd1-usXX';

// In your gatsby-config.js file
require('dotenv').config({
  path: `.env.${process.env.NODE_ENV}`,
});

module.exports = {
  // ...
  plugins: [
    {
      resolve: 'gatsby-source-mailchimp',
      options: {
        key: process.env.MAILCHIMP_KEY,
        rootURL: '[https://usXX.api.mailchimp.com/3.0',](https://usxx.api.mailchimp.com/3.0%27,)
        // ...
      },
    },
  ],
  // ...
};

Recently, the Laravel team announced a Laravel Fortify. A framework agnostic authentication backend for Laravel applications. It provides registration, authentication along with two-factor authentication.

As said above, it is framework agnostic, so it doesn't provide any blade views with it. You can implement views of your choice of the frontend. Blade, Vue, React with Bootstrap or TailwindCSS, or any other CSS framework.

Today we are going to see how we can use Laravel Fortify with one of the most popular Bootstrap 4 theme AdminLTE v3.

We can actually do that in minutes with the package that we already developed called Laravel UI AdminLTE

This package also works with the previous laravel version to have an authentication system with Laravel UI for Laravel Frontend Scaffolding.

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

Install Packages

Install Laravel Fortify and Laravel UI AdminLTE by the following command,

composer require laravel/fortify infyomlabs/laravel-ui-adminlte

Publish Fortify Resources

This command will publish all required actions in the app/Actions directory along with the Fortify configuration file and migration for two-factor authentication.

php artisan vendor:publish --provider="Laravel\Fortify\FortifyServiceProvider"

Run Migrations

Then run migrations,

php artisan migrate

Add Fortify Service Provider

Next step, add published FortifyServiceProvider to config/app.php

Run AdminLTE Fortify Command

Run the following command,

php artisan ui adminlte-fortify --auth

Install Node Modules and Run a Build

As a next step, install required npm modules and run a build,

npm install && npm run dev

And we are done. Now visit the home page and you should be able to see the full authentication system working including,

Login Registration Forgot Password Reset Password Home page

Laravel AdminLTE UI also provides a starting layout with a sidebar menu and header once you login. so you are all set to go.

Lots of people ask me frequently, "Which are the laravel packages that you use in almost all projects?" when we meet in Meetup or any other events regardless of its online or physical events.

Let me describe today some of the packages that we almost use in all of the projects.

We have been working in Laravel for almost 7+ years and in these years we have used lots of packages, some from the community and some of our own.

I am categorizing these into 2 categories.

1. Most used packages
2. Common Need/Functionality specific packages

Most used packages

These are the packages which must be included in all of our projects. No Excuses.

barryvdh/laravel-ide-helper

Laravel exposes a lot of magic methods and properties. IDE Helper is a very good package when it comes to auto-complete those properties and methods. Even it does an amazing job while refactoring properties or methods of the model.

barryvdh/laravel-debugbar

The second one is from the same author, debugbar helps to debug the request in terms of the number of queries fired, time taken by each query, number models retrieved from db, time taken by each request, and much more.

imanghafoori/laravel-microscope

Laravel Microscope improves the readability of your code. Early returns, unnecessary else statements, and many more. so your code looks clean and efficient in terms of execution as well.

beyondcode/laravel-query-detector

One of the problems that we face is, missing eager loading. In ongoing development, sometimes we add relationships objects in the loops, and then laravel fires tons of queries to the database. Laravel Query Detector detects that and gives a warning while developing the environment.

InfyOmLabs/laravel-generator

No application can be ever built without a few CRUDs. CRUDs are essential in almost all web applications. Also, APIs of CRUDs are essential while building a backend for Mobile or Frontend apps. Laravel Generator is our own developed package that we use in all of the applications to make the CRUD building process faster. It can be used with two themes right now, AdminLTE and CoreUI. But it's also frontend framework agnostic.

Common Need/Functionality specific packages

These are the packages that are used when we particularly need that kind of functionality in the application.

• Single Page application without JS - Livewire
• Role Permissions - spatie/laravel-permission
• Media Management - spatie/laravel-medialibrary
• Full Text Search - Laravel Scout
• Payment - Laravel Cashier
• Frontend Scaffolding - Laravel UI AdminLTE & Laravel UI CoreUI
• APIs token management - Laravel Sanctum
• Realtime Apps - Laravel Echo with Pusher & Laravel Echo Server
• One Signal - Shailesh OneSignal

Will keep this list updating.

We have been working on an inventory system for one of our clients for a long time and recently, what we needed was to retrieve inventory item information by UPC code or ISBN or EAN. so the end customer does not need to fill a full form with all the details.

We implemented a feature where customers can just enter or scan UPC/ISBN/EAN code on the mobile app and we retrieve all the information of the product and auto-fill it with an image of the product as well.

So we started using UPCItemDB which has a very nice database of items. You can call their API and retrieve information about the product by sending UPC code. It has a free plan that you can use for trial purposes.

But there was no proper PHP or Laravel package for that, so we decided to make our own and publish it to Github.

It's called laravel-upcitemdb and here is the link for it: https://github.com/InfyOmLabs/laravel-upcitemdb

Here are the installation steps and how to use this package.

Installation

Install the package by the following command,

composer require infyomlabs/laravel-upcitemdb 

Publish the config file

Run the following command to publish config file,

php artisan vendor:publish --provider="InfyOm\UPCItemDB\UPCItemDBServiceProvider" 

Add Facade

Add the Facade to your config/app.php into aliases section,

'UPCItemDB' => \InfyOm\UPCItemDB\UPCItemDB::class, 

Usage

Lookup

For UPC Lookup, use the lookup method by calling,

\UPCItemDB::lookup('4002293401102'); 

Search

For Search API, you can use the search method,

\UPCItemDB::search('iphone 6'); 
\UPCItemDB::search('iphone 6', ['brand' => 'apple']);
