EloqViz (eloqviz/laravel-eloquent-viz)

EloqViz is a small Laravel package for developers who need to see Eloquent relationships at a glance—especially in large codebases with many models and edges. There is no dashboard or extra ceremony: scan Model classes, render a directed graph (or JSON), and focus the view when the full picture is too dense.

This repository is the package source (PHP, Blade, bundled Cytoscape UI). Consume it via Composer inside any Laravel application; local work here uses Orchestra Testbench for tests instead of maintaining a demo Laravel app.

Available on Packagist: eloqviz/laravel-eloquent-viz

Expectations (what this is and isn’t)

EloqViz is an inspection and orientation tool—it reflects what Eloquent declares in model code (relation methods you can probe), not a substitute for migrations, DB dumps, or governance suites.

Smaller apps with a handful of models often don’t need a graph; value scales with size and unfamiliarity. Teams sometimes pipe the JSON into custom checks or docs—that’s optional and up to you.

What you get

• Routes (no route file) — The service provider registers routes in code, so installing the package is enough (GET /{prefix} for the UI, GET /{prefix}/graph for JSON). You do not need to paste routes into routes/web.php; adjust route_prefix and middleware in config when publishing.
• Web UI — Interactive graph (Cytoscape.js): stable FQCN node ids, configurable labels, search across label / FQCN / file path, scan notes (warnings + skipped relation probes), selection panel shows FQCN + file for each model.
• JSON (graphVersion 2) — Full graph payload with diagnostics (see below).
• Artisan — php artisan eloquent:graph prints the same JSON. Use --path= repeatedly (or once) to override config directories.

Relationships are discovered by inspecting public relation methods on each non-abstract Eloquent model. Each candidate method runs once inside Model::withoutEvents() and Connection::pretend() on that model’s connection so typical relations never hit the database.

Requirements

• PHP 8.2+
• Laravel 11.44+ or 12.x

Install in a Laravel application

composer require eloqviz/laravel-eloquent-viz
php artisan vendor:publish --tag=eloquent-viz

That single tag publishes config/eloquent-viz.php and the bundled JS under public/vendor/eloquent-viz/. Granular tags eloquent-viz-assets / eloquent-viz-config still exist.

Then visit /{your-prefix} (default /eloquent-viz). /{prefix}/graph returns JSON only.

When APP_ENV=production, EloqViz does not register HTTP routes or the eloquent:graph Artisan command—the graph is unreachable and the inspector cannot be run via Artisan. Outside production you can still add auth or custom middleware via middleware as needed.

Configuration (config/eloquent-viz.php)

Configuration is PHP only (no .env keys from this package).

models_paths example

'models_paths' => [
    app_path('Models'),
    base_path('modules/Billing/src/Models'),
],

JSON API (GET {prefix}/graph, eloquent:graph)

graphVersion is 2. Breaking change from older builds: nodes are objects, edges.from / edges.to are FQCNs (same as node id), not short class names.

Payload shape

• graphVersion: 2
• nodes: [{ "id": "<fqcn>", "label": "<display>", "fqcn": "<fqcn>", "file": "<optional relative path>" }]
• edges: [{ "from": "<fqcn>", "to": "<fqcn|null>", "type": "belongsTo", "smart": { ... }, "multiplicity"?: n }]
• warnings: [{ "code": "...", "message": "...", ... }], e.g. graph.external_model when a related class is outside models_paths, or graph.ambiguous_basename / graph.ambiguous_default_user when ?model= or default User focus is ambiguous.
• skippedRelations: [{ "model": "<declaring fqcn>", "method": "...", "reason": "..." }] for methods that advertise a relation return type but do not yield a Relation at runtime.
• availableModels (HTTP only): [{ "id": "<fqcn>", "label": "<display>" }] for the root-model dropdown (full scan, no component filter).
• selectedModel: FQCN of the focused model, or null (all models / no default when ambiguous).

?model= accepts either a full class name or a basename when it is unique among scanned models.

Honest limits

The graph is best-effort static + one guarded call per candidate method under pretend() / withoutEvents(). That is the right trade-off for most apps, not a guarantee for every pattern.

• Cross-connection / exotic relations may still run outside the scanned model’s pretend() scope; warnings and skipped relations record what we could detect.
• Abstract base Model classes are not listed as nodes.
• Relations defined only outside model methods (raw query builders, arbitrary PHP) will not appear as edges.

If you need a line in your internal docs: “EloqViz shows the Eloquent surface of the codebase you configured to scan—not the full business or database story.”
