Upgrading Filament from v3 to v4 in a live, large project involves careful planning, backup, and testing, as v4 includes several breaking changes. Here’s a step-by-step approach:
1. Review the Upgrade Guide
- Visit the official Filament v4 Upgrade Guide and read it thoroughly. Make note of any deprecated features or breaking changes relevant to your project.
2. Backup
- Backup your entire project and database. If possible, use version control (e.g., git) and create a new branch for the upgrade.
3. Update Composer Dependencies
- Update Filament and related packages:
composer require filament/filament:"^4.0" filament/forms:"^4.0" filament/tables:"^4.0" filament/support:"^4.0" --with-all-dependencies
- If you use community plugins, check their compatibility with v4 and update them as well.
4. Review and Update Configuration Files
- Some config files or published assets may need to be updated. Check for new or changed config options:
php artisan vendor:publish --tag=filament-config --force
5. Update Your Code
- Search for deprecated classes, methods, or properties in your resources (
resources/,app/Filament/, etc). - Refactor according to the Upgrade Guide.
For example, replace:
use Filament\Forms\Components\TextInput;
with (if namespace changed in v4):
use Filament\Forms\Components\TextInput;
Check for updates regarding panels, pages, components, etc.
6. Test Everything Locally
- Run your tests (
php artisan test) and manually navigate through your Filament admin panel. - Fix any errors or warnings.
7. Deploy Incrementally
- If possible, deploy to a staging environment first.
- Once confirmed, deploy to production during a scheduled maintenance window.
8. Clear Caches
- After deployment, clear caches:
php artisan cache:clear
php artisan config:clear
php artisan view:clear
9. Watch for Bugs
- Monitor logs and gather feedback from users to catch any issues missed during testing.
Summary:
Always refer to Filament’s official upgrade guide for the full list of changes. Test thoroughly, especially on a large or live project, before deploying to production.
