Column Types & Modifiers
Laravel's Schema Builder supports dozens of column types and modifiers. Column types map to database-specific types automatically. Modifiers like nullable(), default(), unsigned(), and unique() customize column behavior.
Common Column Types
- $table->id() - Auto-incrementing BIGINT primary key
- $table->string('name', 255) - VARCHAR
- $table->text('body') - TEXT for long content
- $table->integer('count') / bigInteger / tinyInteger / smallInteger
- $table->decimal('price', 8, 2) - Precise decimal numbers (money)
- $table->boolean('active') - TINYINT(1) true/false
- $table->json('options') - JSON column (native JSON in MySQL/PostgreSQL)
- $table->timestamp('published_at') - TIMESTAMP
- $table->date('birthday') / time('alarm_time') / dateTime('event_at')
- $table->enum('status', ['draft', 'published', 'archived'])
- $table->foreignId('user_id')->constrained() - Foreign key with constraint
- $table->uuid('uuid') - UUID column for non-sequential identifiers
Column Modifiers
$table->string('email')->nullable(); // Allows NULL
$table->integer('votes')->default(0); // Default value
$table->string('name')->unique(); // Unique constraint
$table->bigInteger('votes')->unsigned(); // No negative values
$table->string('bio')->after('name'); // Column position
$table->string('old_col')->change(); // Modify existing column
$table->dropColumn('old_col'); // Remove columnIndustry 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 Column Types Modifiers in small, isolated examples before integrating into larger projects. Breaking concepts into small experiments builds genuine understanding faster than reading alone.
php artisan test. Feature tests most valuable. Use factories + seeders. Aim for 80% coverage.
Practice Task
Note
Practice Task - (1) Write a working example of Column Types Modifiers 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 Column Types Modifiers is skipping edge case testing - empty inputs, null values, and unexpected data types. Always validate boundary conditions to write robust, production-ready laravel code.
