## Installation

```bash
$ go get github.com/zeiss/fiber-authz
```

## Usage

- [x] [OpenFGA](https://openfga.dev/)
- [x] Team-based access control
- [x] Role-based access control
- [x] Noop (for testing)

Any authorization model can be implemented by implementing the `Authorizer` interface.

## OpenAPI

Using [OpenAPI Extensions](https://swagger.io/docs/specification/openapi-extensions/) individual operations can be protected with [OpenFGA](https://openfga.dev/).

```yaml
x-fiber-authz-fga:
user:
namespace: user
auth_type: oidc
relation:
name: admin
object:
namespace: system
components:
- in: params
name: teamId
```

There are three parts to the OpenAPI extension:

- `user` - The user namespace and authentication type.
- `relation` - The relation name.
- `object` - The object namespace and components.

Then there are components to construct the relation or object.

- `in` - The location of the component (e.g. `path`).
- `name` - The name of the component (e.g. `teamId`).
- `type` - The type of the component (e.g. `string`).

## Examples

See [examples](https://github.com/zeiss/fiber-authz/tree/master/examples) to understand the provided interfaces.
