custom jwt authentication

[webafra]

Hello.

I want to use this service to develop my own personalized authentication.

1. Find the user
2. Create the JWT access token for that user

let findUser = await this.userRepository.findOne({
      where: {
        mobile: credentials.mobile
      },
      order: ["id DESC"]
    });

    const token = await this.jwtService.generateToken(findUser.id);

    return { access_token: token }

The code I wrote does not work because method (generateToken) inputs argument must be an email and a name.
I want to authenticate with a mobile number.

please help me.

@jannyHou @mrmodise, could you please help with this question? Thanks.

@webafra You can create your own JWT service like this example, then bind it to binding key that authentication-jwt module exported as this.bind(TokenServiceBindings.TOKEN_SERVICE).toClass(JWTService) in the app constructor .

Can we create API without using model and repository in loopback4??

[infortraining]

its impossible

[mrmodise]

@Arathy-sivan very possible. The default ping controller is a good example of such a case

authenticate with a mobile number.

Please see @jannyHou above and let me know if you still need help. I will be glad to help

how can we generate token without using model and repository in loopback4?

[jannyHou]

@Lipinalipi If you don't need persistence, you can just generate token using services like https://github.com/strongloop/loopback-next/blob/master/extensions/authentication-jwt/src/services/jwt.service.ts, see function generateToken.
