### CORS Configuration
CORS (Cross-Origin Resource Sharing) can be configured in two ways:
**Local development** (allows localhost origins only):
```yaml
server:
cors: true
```
**Explicit configuration** (custom origins and settings):
```yaml
server:
cors:
allow_origins: ["https://myapp.com", "https://app.example.com"]
allow_methods: ["GET", "POST", "PUT", "DELETE"]
allow_headers: ["Content-Type", "Authorization"]
allow_credentials: true
max_age: 3600
```
When `cors: true`, the server enables secure localhost-only access for local development. For production, specify exact origins to maintain security.
### Authentication Configuration
> **Breaking Change (v0.2.14)**: The authentication configuration structure has changed. The previous format with `provider_type` and `config` fields has been replaced with a unified `provider_config` field that includes the `type` field. Update your configuration files accordingly.
@ -618,6 +642,54 @@ Content-Type: application/json
}
```
### CORS Configuration
Configure CORS to allow web browsers to make requests from different domains. Disabled by default.
#### Quick Setup
For development, use the simple boolean flag:
```yaml
server:
cors: true # Auto-enables localhost with any port
```
This automatically allows `http://localhost:*` and `https://localhost:*` with secure defaults.
#### Custom Configuration
For specific origins and full control:
```yaml
server:
cors:
allow_origins: ["https://myapp.com", "https://staging.myapp.com"]
allow_credentials: true
allow_methods: ["GET", "POST", "PUT", "DELETE"]
allow_headers: ["Content-Type", "Authorization"]
allow_origin_regex: "https://.*\\.example\\.com" # Optional regex pattern
expose_headers: ["X-Total-Count"]
max_age: 86400
```
#### Configuration Options
| Field | Description | Default |
| -------------------- | ---------------------------------------------- | ------- |
| `allow_origins` | List of allowed origins. Use `["*"]` for any. | `["*"]` |
| `allow_origin_regex` | Regex pattern for allowed origins (optional). | `None` |
| `allow_methods` | Allowed HTTP methods. | `["*"]` |
| `allow_headers` | Allowed headers. | `["*"]` |
| `allow_credentials` | Allow credentials (cookies, auth headers). | `false` |
| `expose_headers` | Headers exposed to browser. | `[]` |
| `max_age` | Preflight cache time (seconds). | `600` |
**Security Notes**:
- `allow_credentials: true` requires explicit origins (no wildcards)
- `cors: true` enables localhost access only (secure for development)
- For public APIs, always specify exact allowed origins
## Extending to handle Safety
Configuring Safety can be a little involved so it is instructive to go through an example.
