Layout Component Bundle Laravel Package

Getting Started

Before anything else, verify what you're actually installing. With 0 stars and 0 dependents, there is no community usage to lean on, so the source is the documentation. Confirm the real Composer name first (repo names and Packagist names frequently diverge):

composer show -a igdr/layout-component-bundle

Then:

1. Require it pinned. Given zero downstream users, do not float versions:

   composer require igdr/layout-component-bundle:^0.1 --prefer-stable
   

2. Register the bundle manually. Flex recipes are auto-generated from install counts; a package with no dependents almost certainly has no recipe. Add it to config/bundles.php yourself and clear cache. If the class isn't where you expect, list it:

   bin/console debug:container --parameter=kernel.bundles
   

3. Read src/ in this order, which is the fastest way to reverse-engineer any Symfony bundle:
   • *Bundle.php — what the bundle actually hooks into
   • DependencyInjection/Configuration.php — the entire configuration surface, with defaults
   • DependencyInjection/*Extension.php — which services/tags get registered and under what conditions
   • Resources/config/*.yaml or config/ — service definitions and tags
   • Resources/views/ (or templates/) — the Twig namespace you'll be calling

First use case: render one layout component in an existing template and look at the HTML it emits. Do this in isolation on a scratch route or a render(controller(...)) inside an empty base template, not inside your real layout — you want to see the bundle's markup and CSS/JS requirements before it interacts with your own asset pipeline:

{# templates/scratch.html.twig #}
{{ component('some-layout-component') }}   {# verify exact syntax from the bundle's own templates #}

If the README shows nothing usable, the bundle's own test suite (if present) under tests/ is the most reliable usage example you'll get.

Implementation Patterns

Treat it as a presentation-layer dependency, nothing more. A layout/component bundle should not be reachable from your domain or application services. The clean pattern is:

Controller -> ViewModel -> Twig template -> bundle component

If the bundle exposes services you want in application code, wrap them in a thin interface of your own so the bundle can be swapped or dropped without a refactor. With 0 dependents, assume you may be the only person who ever removes it.

Centralize the seam. Never call bundle tags/components directly from feature templates. Put them behind your own macro or a single set of layout templates:

{# templates/_layout/component.html.twig #}
{% macro render(name, props = {}) %}
    {{ component(name, props) }}
{% endmacro %}

Every call site goes through the macro. When the bundle's API changes between patch versions, or when you migrate off it, you edit one file.

Override, don't fork. Symfony template resolution lets you shadow bundle templates without touching vendor code:

templates/bundles/<BundleName>/<path matching the bundle's views>

This is the correct extension point for styling and markup. Forking vendor gives you a permanent merge burden on an unmaintained package.

Decorate services for behavior changes. If a service registered by the bundle needs extra logic (asset collection, caching, data enrichment), use services.yaml decoration rather than subclassing or editing vendor config:

App\Layout\CachingRenderer:
    decorates: igdr.layout_component.some_renderer
    arguments: ['@.inner']

Keep layout definitions in data, not templates. If the bundle is a layout builder (pages composed of component instances), store the composition as structured config/YAML or a DB row and hydrate it, rather than hardcoding component nesting in Twig. This is what makes a layout system maintainable past the third page.

Test the rendered output, not the internals. Functional Twig rendering assertions are the only stable contract you have with an undocumented bundle:

$html = $this->renderTwig('scratch.html.twig', [...]);
$this->assertStringContainsString('data-layout-component', $html);

Snapshot the output on upgrade so a silent markup change shows up in CI, not production.

Gotchas and Tips

• Vendor risk is the headline. 0 stars and 0 dependents means no maintenance guarantee, no security advisories reaching you, no Stack Overflow answers, and no one to ask. Pin to an exact version, commit composer.lock, and keep a written note of what depends on it. Evaluate the composer.json require constraints — if it permits a wide Symfony range, verify it against your actual Symfony version before adopting.
• Assume no Flex recipe. If composer require doesn't add the bundle to config/bundles.php, that's expected, not broken. Register manually.
• Config quirks live in Configuration.php. Defaults there are the only authoritative documentation of what the bundle expects. If the bundle has no Configuration.php, it takes no config and everything is service-level — adjust your assumptions accordingly.
• Twig namespace confusion. Bundle templates are typically registered under a namespace derived from the bundle name (e.g. @LayoutComponent/...). Confirm with:

  bin/console debug:twig
  

  This single command resolves most "template not found" issues.
• Debugging services and tags:

  bin/console debug:container --tag=twig.extension
  bin/console debug:container <service_id>
  

  Use these to confirm the bundle registered what you think it did — particularly if an extension was conditionally registered based on config.
• Clear cache after config changes. Bundle config changes are not hot-reloaded in prod, and stale Twig caches mask override mistakes in dev if auto_reload is off.
• Nested component recursion can blow up. Layout systems that render components inside components are prone to unbounded depth on malformed data. If you load compositions from a DB, validate depth before rendering.
• Strict variables. If you enable strict_variables, undocumented optional props on components will throw. Check the bundle's templates for default filters before turning it on, or you'll get failures you can't trace to your own code.
• Extension points, in order of preference: template override → service decoration → event listener/subscriber → config. Editing vendor/ is never on the list; it disappears on the next composer install.
• If the README is empty or broken, the tests/ directory and the Resources/config service definitions are the real specification. Budget an afternoon to read both before promising a feature built on this package.
