falguard 0.1

Features

• Validation of OpenAPI (Swagger) schema

• Error serialization compliant with JSON:API specification

• Validator may be used either as a hook or a middleware component

Usage

Instantiate Validator with the path to OpenAPI specification…

import falguard

validator = falguard.Validator('spec.json')

…and use it as the hook on the responder…

class Resource:

    @falcon.before(validator)
    def on_get(self, request, response, **validated):
        pass

…or the hook on the whole resource…

@falcon.before(validator)
class Resource:
    pass

…or globally, as the middleware component.

import falcon

api = falcon.API(middleware=validator)

All validated parameters (path, query, body) are injected back to the responder so it MUST accept relevant number of arguments, eg.

class Resource:

    def on_put(self, request, response, resource_id, data):
        pass

    def on_post(self, request, response, **validated):
        pass
