Notes

The middleware property on the options param is useful for applying universal middleware such as CORS headers, across an entire API from a single place.

Examples

Create an API

from nitric.resources import api

publicApi = api("public")

Create an API with universal middleware

from nitric.resources import api, ApiOptions
from myapp.middleware import auth

publicApi = api("public", ApiOptions(middleware=[auth]))

Define middleware

async def auth(ctx, nxt: HttpMiddleware):
  # Perform auth validation.
  return await nxt(ctx)

Notes

Middleware services are supplied a HttpContext object and a next() function which calls the next middleware in the chain.

Create an API with a base path

If you need to put all the routes in your api below a shared base path, you can do that with the path option. In this example we ensure all routes start with /api/v1/ before the route specific path.

from nitric.resources import api, ApiOptions

publicApi = api("public", ApiOptions(path="/api/v1/"))

Apply JWT authentication to an API

from nitric.resources import api, ApiOptions
from nitric.resources.apis import JwtSecurityDefinition

publicApi = api("public", ApiOptions(
    security_definitions={
        "user": JwtSecurityDefinition(
            issuer="https://example-issuer.com",
            audiences=['YOUR-AUDIENCES']
        )
    },
    security={
        "user": []
    }
))
