Every permission a subject holds on a resource is packed into a single integer column, so checks are a single indexed query with a bitwise `AND` — no joins, no pivot-row lookups. It supports both **object-level** (per-record) and **global** (resource-wide) grants out of the box. Why bitmasks? ------------- [](#why-bitmasks) Traditional permission packages store each grant as one or more rows across several pivot tables. This package stores all of a subject's permissions on a given resource in one `BIGINT`: Pivot-table approachBitmask (this package)Storage per grantmultiple rows across pivot tablesa single integer columnPermission checkrow lookups / joinsone bitwise `AND` in a single indexed queryObject-level permissionsnot first-classnative (`resource_type` + nullable `resource_id`)Combining permissionsinsert / delete rowsbitwise `OR` / `AND`**Trade-off:** the number of distinct permissions per resource type is capped by the integer width (64 with `BIGINT`), and there are no built-in roles/caching helpers. It's optimized for fast, fine-grained, per-resource checks. Requirements ------------ [](#requirements) - PHP `^8.2` - Laravel 10, 11, 12 ,or 13 (`illuminate/database`, `illuminate/support`) Installation ------------ [](#installation) ``` composer require halaabdulmottleeb/bitmask-permissions ``` The service provider is auto-discovered. Publish and run the migration: ``` php artisan vendor:publish --tag=bitmask-permissions-migrations php artisan migrate ``` Optionally publish the config file to change the table name: ``` php artisan vendor:publish --tag=bitmask-permissions-config ``` Usage ----- [](#usage) ### 1. Define your permissions as bit values [](#1-define-your-permissions-as-bit-values) Each permission is a single bit — use powers of two. An enum is a clean way to do this: ``` enum PostPermission: int { case READ = 1; // 0001 case WRITE = 2; // 0010 case UPDATE = 4; // 0100 case DELETE = 8; // 1000 } ``` ### 2. Add the trait to any model that can hold permissions [](#2-add-the-trait-to-any-model-that-can-hold-permissions) ``` use HalaAbdulmottleb\BitmaskPermissions\Traits\HasBitmaskPermissions; use Illuminate\Database\Eloquent\Model; class User extends Model { use HasBitmaskPermissions; } ``` Any Eloquent model works as the **subject** (User, Team, ApiClient, ...) because the relation is polymorphic. ### 3. Grant, check, and revoke [](#3-grant-check-and-revoke) ``` $user->grantPermissionTo(PostPermission::READ->value, $post); $user->grantPermissionTo(PostPermission::WRITE->value, $post); $user->hasPermissionTo(PostPermission::READ->value, $post); // true $user->hasPermissionTo(PostPermission::DELETE->value, $post); // false $user->revokePermission(PostPermission::WRITE->value, $post); ``` ### Combining permissions [](#combining-permissions) Because permissions are bits, you can grant several at once with a bitwise `OR`: ``` $user->grantPermissionTo( PostPermission::READ->value | PostPermission::WRITE->value, $post ); ``` `hasPermissionTo()` checks that **all** requested bits are present (`(mask & permission) = permission`). ### Global (resource-wide) grants [](#global-resource-wide-grants) The `resource_id` column is nullable. A grant with a null `resource_id` applies to **every** record of that resource type, and `hasPermissionTo()` matches either the specific record or the global grant. API --- [](#api) The `HasBitmaskPermissions` trait adds: MethodDescription`grantPermissionTo(int $permission, Model $resource)`Adds the permission bit(s) for the subject on the resource.`hasPermissionTo(int $permission, Model $resource): bool`Returns `true` if the subject has all requested bits (record-specific or global).`revokePermission(int $permission, Model $resource)`Clears the permission bit(s) for the subject on the resource.`grantPermissions(): MorphMany`The underlying polymorphic relation to `PermissionGrant`.Configuration ------------- [](#configuration) `config/bitmask-permissions.php`: ``` return [ 'table' => 'permission_grants', ]; ``` Schema ------ [](#schema) A single table holds everything: - `subject_type` / `subject_id` — polymorphic owner of the permissions - `resource_type` — the resource class (via morph map) - `resource_id` — nullable; `null` means a global grant for that resource type - `mask` — the bitmask of granted permissions - unique on `(subject_type, subject_id, resource_type, resource_id)` — one row per subject–resource pair Testing ------- [](#testing) ``` composer install vendor/bin/pest ``` Tests run against an in-memory SQLite database via Orchestra Testbench.
