What is Laravel service provider boot vs register lifecycle?
Updated May 16, 2026
Short answer
register binds services to the container, while boot executes after all services are registered.
Deep explanation
Service providers are the central place for Laravel bootstrapping. The register method is used to bind classes into the service container. The boot method runs after all providers are registered, making it suitable for event listeners, route binding, and model observers. Understanding this lifecycle is essential for correct dependency initialization.
Real-world example
Used in package development to initialize services properly.
Common mistakes
- Using boot for bindings causing circular dependency issues.
Follow-up questions
- Why register runs before boot?
- What happens if boot depends on unregistered service?
