import { ExecutionContext, Injectable, Type } from '@nestjs/common';
import { Reflector } from '@nestjs/core';
import { AuthGuard } from '@nestjs/passport';
import { Observable } from 'rxjs';

import {
IS_PUBLIC_KEY,
JWT_GUARD,
} from '@/application/api/http-rest/authentication/constants';

@Injectable()
export class HttpJwtAuthGuard extends AuthGuard(JWT_GUARD) {
public constructor(private readonly reflector: Reflector = new Reflector()) {
super();
}

public canActivate(
context: ExecutionContext,
): boolean | Promise | Observable {
const contextType: string = context.getType();

if (contextType === 'telegraf') {
  return true;
}

const isPublic: boolean = this.reflector.getAllAndOverride<boolean>(
  IS_PUBLIC_KEY,
  [context.getHandler(), context.getClass()],
);

if (isPublic) {
  return true;
}

return super.canActivate(context);

}
}

HttpJwtAuthGuard

It has to work inside the application, and the function is called from another service
