Laravel Query Gate

A declarative API layer for Laravel that turns Eloquent models into fully featured REST endpoints — with filtering, sorting, actions, versioning, OpenAPI docs, and a type-safe TypeScript SDK.

Features

• Declarative API definition — define filters, sorts, selects, and actions directly on your model
• CRUD actions — built-in create, update, delete, and detail with validation, policies, and custom handlers
• Custom actions — extend your API with reusable action classes
• API versioning — version your endpoints with automatic changelog generation
• OpenAPI documentation — auto-generated spec and UI out of the box
• TypeScript code generation — generate type-safe contracts with php artisan qg:types
• Frontend SDK — fully typed, framework-agnostic query builder for the frontend
• Caching & pagination — cursor and offset pagination, built-in cache support

Requirements

• PHP 8.2+
• Laravel 10, 11, or 12

Installation

composer require behindsolution/laravel-query-gate

Publish the config file:

php artisan vendor:publish --tag=query-gate-config

Quick Start

Add the trait to your model and define the query gate:

use BehindSolution\LaravelQueryGate\Traits\HasQueryGate;
use BehindSolution\LaravelQueryGate\Support\QueryGate;

class User extends Model
{
    use HasQueryGate;

    public static function queryGate(): QueryGate
    {
        return QueryGate::make()
            ->alias('users')
            ->select(['id', 'name', 'email', 'created_at'])
            ->filters(['name' => 'string', 'email' => 'email'])
            ->allowedFilters(['name' => ['like', 'eq'], 'email' => ['eq']])
            ->sorts(['name', 'created_at']);
    }
}

Your API is ready:

GET    /query/users?filter[name][like]=John&sort=-created_at
GET    /query/users/1

Actions

Define mutations with a fluent builder:

QueryGate::make()
    ->alias('posts')
    ->actions(fn ($actions) => $actions
        ->create(fn ($action) => $action
            ->validations(['title' => 'required|string', 'body' => 'required|string'])
            ->policy('create')
        )
        ->update(fn ($action) => $action
            ->validations(['title' => 'string', 'body' => 'string'])
            ->policy('update')
        )
        ->delete(fn ($action) => $action->policy('delete'))
        ->detail()
    );

Custom actions:

->actions(fn ($actions) => $actions
    ->use(PublishPostAction::class)
)

API Versioning

QueryGate::make()
    ->alias('users')
    ->version('2024-01-01', fn ($gate) => $gate
        ->select(['id', 'name', 'email'])
        ->filters(['name' => 'string'])
    )
    ->version('2024-06-01', fn ($gate) => $gate
        ->select(['id', 'name', 'email', 'avatar'])
        ->filters(['name' => 'string', 'email' => 'email'])
    );

Clients select a version via the X-Query-Version header or ?version= query parameter. A changelog is auto-generated at GET /query/users/__changelog.

TypeScript Code Generation

Generate type-safe contracts from your API definitions:

php artisan qg:types --output=resources/ts/contracts

Output example:

export interface UserEntity {
  id: number;
  name: string;
  email: string;
}

export interface UserCreatePayload {
  name: string;
  email: string;
}

export interface UserResourceContract {
  get: UserEntity;
  create: { payload: UserCreatePayload; response: UserEntity };
  // ...
}

Frontend SDK

Install the companion SDK:

npm install laravel-query-gate-sdk

import { configureQueryGate, queryGate } from 'laravel-query-gate-sdk'

configureQueryGate({ baseUrl: 'https://api.example.com/query' })

// List with filters and sorting
const users = await queryGate<UserResourceContract>('users')
  .filter('name', 'like', 'John')
  .sort('created_at', 'desc')
  .get()

// Create
await queryGate<UserResourceContract>('users')
  .post({ name: 'Jane', email: 'jane@example.com' })

// Update
await queryGate<UserResourceContract>('users').id(1)
  .patch({ name: 'Jane Doe' })

// Custom action
await queryGate<PostResourceContract>('posts').id(1)
  .action('publish').post()

OpenAPI Documentation

Enable in config/query-gate.php:

'openAPI' => [
    'enabled' => true,
],

Access the generated docs at GET /query/docs (UI) or GET /query/docs.json (spec).
