Database Configuration & Supported Drivers
Laravel supports MySQL, PostgreSQL, SQLite, and SQL Server out of the box. Database connections are configured in config/database.php, with credentials read from the .env file. You can define multiple connections and switch between them dynamically.
Database Configuration
# .env file
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=my_app
DB_USERNAME=root
DB_PASSWORD=secret
# For SQLite (zero config - great for development)
DB_CONNECTION=sqlite
# Creates database/database.sqlite automatically
# For PostgreSQL
DB_CONNECTION=pgsql
DB_HOST=127.0.0.1
DB_PORT=5432
DB_DATABASE=my_appChoosing a Database
- MySQL: Most popular choice for Laravel apps. Great community support, widely available on shared hosting, solid performance for most workloads
- PostgreSQL: More advanced features - full-text search, JSONB columns, advanced indexing, better ACID compliance. Preferred for complex data models and enterprise applications
- SQLite: File-based, zero configuration. Perfect for local development, testing, and small applications. Laravel uses it for in-memory test databases
- SQL Server: For Microsoft/enterprise environments. Laravel supports it natively through the sqlsrv driver
Industry Best Practices
- Always write tests for this functionality - it's the most reliable way to catch regressions when you refactor or update packages
- Document your implementation decisions in code comments, especially when you deviate from Laravel conventions - future team members (including yourself) will thank you
- Follow the single responsibility principle: each class does one thing. If a method grows beyond 20 lines, consider extracting helper methods or moving logic to a service class
- Profile performance with Laravel Debugbar (composer require barryvdh/laravel-debugbar) during development - it shows query counts, memory usage, and timeline for every request
- Keep dependencies up to date: run composer audit regularly to check for security vulnerabilities in your package dependencies

Tip
Tip
Practice Database Configuration Supported Drivers in small, isolated examples before integrating into larger projects. Breaking concepts into small experiments builds genuine understanding faster than reading alone.
Middleware = filters that run before/after your controller logic
Practice Task
Note
Practice Task - (1) Write a working example of Database Configuration Supported Drivers from scratch without looking at notes. (2) Modify it to handle an edge case (empty input, null value, or error state). (3) Share your solution in the Priygop community for feedback.
Quick Quiz
Common Mistake
Warning
A common mistake with Database Configuration Supported Drivers is skipping edge case testing - empty inputs, null values, and unexpected data types. Always validate boundary conditions to write robust, production-ready laravel code.
