Balancing Filament Versions in Platform Development

When developing a platform like Reimpact's, managing dependencies across different environments can become a challenge, especially when using frameworks like Filament. This post explores how to handle version mismatches gracefully during development and deployment.

The Problem: Version Conflicts

Imagine a scenario where your production environment relies on an older version of a framework (e.g., Filament v5), while your local development environment uses the latest version (e.g., Filament v3). Without proper safeguards, this discrepancy can lead to errors and prevent developers from working effectively.

The Solution: Conditional Logic and API Compatibility

To mitigate this, a two-pronged approach can be adopted:

1. API Restoration: Ensure that the codebase remains compatible with the older version of the framework used in production. This might involve reverting certain files or code sections to the older API.
2. Conditional Resource Discovery: Guard resource discovery with a class_exists check. This prevents the application from crashing in local development environments where the newer version of the framework might have different class structures.

Here's how you can conditionally load resources based on class existence in PHP:

if (class_exists(\Filament\PanelProvider::class)) {
    // Load resources compatible with Filament
    Filament::registerResources([
        CustomResource::class,
    ]);
}

This code snippet ensures that CustomResource is only registered if the Filament class PanelProvider exists, preventing errors when running the application in different environments.

Ignoring non-compatible code

PHPStan analyseAndScan can be configured to exclude certain directories. For example, to exclude the Ecodesign directory, you can add it to the exclude list in your phpstan.neon file.

parameters:
    excludePaths:
        - Ecodesign

The Result: Smooth Development and Deployment

By implementing these strategies, developers can seamlessly switch between different environments without encountering version-related issues. This approach ensures that the production environment remains stable while allowing developers to leverage the latest features and improvements in their local setups.

Actionable Takeaway

When working with rapidly evolving frameworks, always consider the potential for version conflicts between development and production environments. Use conditional logic and API compatibility techniques to create a robust and adaptable codebase.
