// STRATEGY

import { Injectable } from '@nestjs/common';
import { Strategy, ExtractJwt } from 'passport-jwt';
import { PassportStrategy } from '@nestjs/passport';

      jwtFromRequest: ExtractJwt.fromHeader('access-token'),
      ignoreExpiration: false,
      secretOrKey: `${process.env.SECRET_KEY}`,
    });
  }

  async validate(payload: any) {
    return payload;
  }
}



// generate a new guard using the CLI => nest g guard CustomJWTGuard
// GUARD BELOW

import { CanActivate, ExecutionContext, Injectable } from '@nestjs/common';
import { JwtService } from '@nestjs/jwt';
import { Observable } from 'rxjs';

@Injectable()
export class CustomJWTGuard implements CanActivate {
  constructor(private jwtService: JwtService) {}

  canActivate(
    context: ExecutionContext,
  ): boolean | Promise<boolean> | Observable<boolean> {
    const req: Request = context.switchToHttp().getRequest();
    
    const token = req.headers['access-token'];

    const payload_data = this.jwtService.verify(token);

    console.log('VERIFICATION', verification);

    return true;
  }
}

// in your route, protect it like so:

  @UseGuards(AuthGuard('jwt'))
  @Get('test')
  async testReq() {
    console.log('REQUEST SUCCESSFUL');
    return { successs: true };
  }
