Interceptors

In simpler terms, Nestipy offers Interceptor functionality, which functions similarly to how Interceptors work in NestJs, allowing you to intercept requests. Nestipy Interceptor must be a class that extends NestipyInterceptor.

Python

from nestipy.common import Injectable
from nestipy.common import NestipyInterceptor
from nestipy.core import ExecutionContext
from nestipy.types_ import NextFn


@Injectable()
class TestInterceptor(NestipyInterceptor):
    async def intercept(self, context: ExecutionContext, next_fn: NextFn):
        print('Intercepted...')
        return await next_fn()

Apply interceptors

Interceptors can be applied to controllers, specific controller methods, within modules via providers, or even globally across the application.

Python

from nestipy.common import Controller, Post, UseInterceptors, Module, ModuleProviderDict
from nestipy.core import AppKey


@UseInterceptors(TestInterceptor)
@Controller('cats')
class CatsController:

    @UseInterceptors(TestInterceptor)
    @Post()
    async def create(self):
        pass


@Module(
    controllers=[
        CatsController
    ],
    providers=[
        ModuleProviderDict(token=AppKey.APP_INTERCEPTOR, use_class=TestInterceptor)
    ]
)
class AppModule:
    pass

Globally , it works like.

Python

from nestipy.core import NestipyFactory

app = NestipyFactory.create(AppModule)
app.use_global_interceptors(TestInterceptor)

Take a look here for an example.
