How to Build and Publish a Laravel Composer Package from Scratch

Tools and Materials

git

composer

IDE

Preparation

Create a blank Laravel 5.6 project:

composer create-project laravel/laravel laraveltest --prefer-dist

Configure the .env file and database settings.

Create a folder in the project root to hold the package resources.

Package Development Process

Develop the package in a separate project (e.g., a routing and permission validation package) and implement the desired functionality.

Copy the developed file structure into the custom folder of the blank Laravel project (e.g., project_root/dongdong/routeauth ).

Create a src directory and add a ServiceProvider.

In the provider implement two methods: register : bind services into the container. boot : publish assets using publishes . Running php artisan vendor:publish --force copies files to the target folder and overwrites existing ones.

Run composer init in the package folder to generate composer.json , then remove the "type": "project" entry.

Local Testing

Modify the main Laravel project's composer.json to point to the local package directory.

Run composer update , then publish with php artisan vendor:publish --force .

Publishing to Packagist

Create a GitHub repository (e.g., https://github.com/dongdonggo/routeAuth ) and push the package files.

Sign up on Packagist and submit the GitHub repository URL.

After approval, the package can be required with composer require vendor/route-auth . If you previously used a Chinese mirror, switch back to the main Packagist URL before requiring.
