Contract Laravel Package
jeckel-lab/contract
A lightweight Laravel package from Jeckel-Lab for defining and enforcing contracts between components. It helps structure your code around clear interfaces, improving maintainability, testability, and predictable behavior across your application.
jeckel-lab/contract is a lightweight Laravel/PHP package for defining explicit contracts between application components. It helps formalize expected behavior, bind concrete implementations through the container, and keep collaborators decoupled, replaceable, and easy to test.
- Define contracts as clean PHP interfaces
- Automatic container binding for implementations
- Helpers for verifying contract compliance
- Seamless Laravel integration and test-friendly design
Frequently asked questions about Contract
- What is jeckel-lab/contract used for?
- jeckel-lab/contract provides reusable PHP interfaces and contracts that you can share across packages in a Laravel application. It helps you depend on abstractions instead of concrete classes, so implementations can be swapped and tested more easily. The package supplies the contracts; you provide and bind the concrete implementations.
- How do I install jeckel-lab/contract in Laravel?
- Install it with Composer by running composer require jeckel-lab/contract. Because it is a contracts package, it may not include a service provider or configuration file. Check the package README for any optional setup steps after installation.
- Which Laravel versions are supported by jeckel-lab/contract?
- The provided package metadata does not list a specific Laravel version constraint. Before installing, check the composer.json file on Packagist or the GitHub repository for the exact PHP and Laravel requirements. That will confirm compatibility with your application.
- How do I bind a concrete class to a jeckel-lab/contract interface?
- Create a class that implements the interface, then register a binding in a Laravel service provider using the container's bind or singleton method. Type-hint the interface in your controllers, services, or jobs and Laravel will resolve the bound implementation. This keeps your consumers decoupled from the concrete class.
- Can I use jeckel-lab/contract outside of Laravel?
- The package is described as providing reusable PHP interfaces for Laravel applications, and contracts are typically plain PHP interfaces. That means they may be usable in other PHP projects, but the documented focus is Laravel. Confirm the package requirements before using it in a non-Laravel codebase.
- Does jeckel-lab/contract require configuration or a service provider?
- Contract-only packages often need no configuration and may not register a service provider. You usually configure Laravel by binding your chosen implementations in your own service provider. Review the README to see whether this package includes any optional provider or config file.
- How does jeckel-lab/contract help with testing?
- Because your code depends on interfaces, you can bind fake or stub implementations in the Laravel container during tests. This lets you isolate the class under test without relying on real services or infrastructure. The result is faster, more predictable unit tests.
- Is jeckel-lab/contract suitable for production use?
- The package provides interfaces, so it adds little runtime behavior beyond autoloading and normal container resolution. For production, make sure your concrete bindings are registered and that Laravel's caches are rebuilt after deployment. You should also review the repository's release history and open issues before adopting it.
- What are alternatives to jeckel-lab/contract?
- Alternatives include Laravel's built-in contracts, PHP-FIG PSR interfaces, or defining your own package-level interfaces. The best choice depends on whether you need framework-specific abstractions or broad interoperability. jeckel-lab/contract is a lightweight option for sharing contracts across packages.
- How is jeckel-lab/contract maintained?
- The provided metadata does not include maintenance details such as release cadence or support policy. Check Packagist and the GitHub repository for recent commits, tagged releases, and open issues. That will help you judge whether the package is actively maintained for your Laravel version.
