Plugin Overview

Casbin’s plugin ecosystem extends the core with storage backends, framework integrations, and distributed sync. Use plugins to connect Casbin to your database, message bus, or web framework.

Plugin categories

Category	Purpose
Enforcers	Specialized enforcers for particular environments or use cases
Adapters	Connect to storage (databases, files, cloud) for model and policy
Watchers	Sync policy changes across multiple enforcer instances
Dispatchers	Coordinate updates in distributed deployments
Role managers	Custom role/hierarchy logic
Middlewares	Integrations for Kong, GraphQL, and cloud-native stacks

Why use plugins?

• Integrate with your existing DB and infra
• Scale to multiple instances with watchers and dispatchers
• Use framework-specific middlewares (e.g. Nest.js, Gin)
• Run in cloud-native and serverless setups

Getting started

1. Choose the plugin type that fits your need (adapter, watcher, middleware, etc.).
2. Install the package for your language.
3. Configure it when creating or configuring the enforcer.
4. See the plugin’s own docs for options and advanced usage.

Use the sections in this category to find and configure each plugin type.
