NestJS
Use Katman as a NestJS controller — Express or Fastify under the hood.
Register Katman as a NestJS controller. Works with both Express and Fastify adapters.
Setup
// rpc.controller.ts
import { , , , } from "@nestjs/common"
import { } from "katman/nestjs"
import { } from "./rpc"
const = (, {
: () => ({ : getDB(), : .user }),
})
@("rpc")
export class {
@("*")
async (@() : Request, @() : Response) {
return (, )
}
}Procedures are accessible at:
POST /rpc/users/list
POST /rpc/users/createContext from NestJS
The context factory receives the Express/Fastify request. Access guards, pipes, and other NestJS features through the request:
katmanNestHandler(appRouter, {
: () => ({
: .user, // from NestJS AuthGuard
: .ip,
: .headers,
}),
})NestJS's own dependency injection, guards, and interceptors run before the Katman handler. You can use @UseGuards(), @UseInterceptors(), etc. alongside Katman.
