@ChainOfResponsibility / @Handler

Ordered handler chain — call handle(context) to run @Handler methods in order until one handles the request.

Kind	Runtime
Backends	legacy, stage3
Requires generate	No

Example

import { ChainOfResponsibility, Handler } from 'lombok-typescript/legacy';

@ChainOfResponsibility
class AuthMiddleware {
  @Handler({ order: 1 })
  checkToken(req: { token?: string }) {
    return Boolean(req.token);
  }

  @Handler({ order: 2 })
  checkRole(req: { role?: string }) {
    return req.role === 'admin';
  }
}

const ok = new AuthMiddleware().handle({ token: 'x', role: 'admin' });

A handler stops the chain when it returns true or any value other than false / undefined.
