Getting Started

Install with composer require vendor/package; the 0.2 “correct composer.json” note means package metadata/autoloading should be fixed, so verify normal Composer install and Laravel package discovery work before adding custom registration.
Look first at: composer.json for autoload/provider discovery, the README for routing syntax, the package service/resource provider, and any published config/twig.php or routes file.
Publish package resources if the provider supports it: php artisan vendor:publish --provider="Vendor\Package\PackageServiceProvider". Prefer tag-based publishing if documented.
First use case: define one simple route, render one Twig template, and expose one Twig method/function. Keep it small: install, publish, create template, add route, call helper, confirm output.

Implementation Patterns

Simple routing: Keep package routes in a small dedicated file or routes/web.php; use named routes so Twig templates can generate URLs. Apply Laravel middleware (auth, throttle, etc.) at the route level rather than inside templates.
Twig methods: Register small, deterministic template helpers through the package’s documented extension/config point. Keep methods presentation-focused; move domain logic into services/actions and pass prepared data into the view.
Resource provider: Publish config/views once, then override package views under resources/views/vendor/... rather than editing vendor/. Treat published config as application config and commit it.
Day-to-day workflow: add route → render Twig template → call helper → test response. Use php artisan route:list to verify routes and Laravel’s HTTP tests to assert rendered output.
Integration tip: pass only needed data from controllers into Twig; use Laravel’s route/model binding where supported, but verify package routing handles it before relying on advanced route features.

0.2 is early; pin the version and read the changelog before upgrading. Public APIs for routing and Twig method registration may still change.
After updating, run composer dump-autoload and confirm the provider is discovered. If not, register it manually in bootstrap/providers.php or config/app.php.
Resource publishing can overwrite local changes; publish first, then customize. Use --force only when you intend to replace published files.
Twig helper naming collisions are easy to create; namespace method names and keep them side-effect free. Clear Twig/Laravel caches when changing helper registration.
Simple routing may not cover every Laravel route feature. Test route caching, middleware, route names, and model binding before standardizing on it.
Debug with php artisan route:list, php artisan config:clear, php artisan view:clear, and php artisan cache:clear. If a Twig method is missing, check registration order and whether the template cache is stale.
Extension points to watch: custom Twig extensions/methods, route macros, view composers, and published resource tags. Prefer documented extension points over editing vendor code.
