How to retreive data from backend to frontend in node application

I’m quite new to node applications, but I have made a frontend in react, and a backend using node and sql. I have a UserLogin component in the frontend, which makes the call after getting user data:

  submitLoginForm(e) {
    e.preventDefault();

    const { email, password } = this.state;
    const { login } = this.props;

    const validEmail = validateEmail(email);
    login(email, password); //login function in frontend
  }

The login function is as follows:

export function login(email, password) {
    return async (dispatch) => {
        try {
            const resp = await callLoginApi(email, password);
            console.log("Response is", resp);
        } catch (err) {
            console.log("error is", err);
        }
    };
}

function callLoginApi(email, password) {
    return axios.post(API.auth.login, {
        email,
        password
    });
}

In the backend, this auth.controller makes the login call:

module.exports.login = utils.asyncRequest((req) => {
    const { body } = req;
    return authService.generateToken(dbService.User, body.email, body.password);
});

and this is what generateToken in authService looks like :

module.exports.generateToken = async (Model = dbService.User, email, password, ssoData) => {

user = await dbService.querySingle(Model, {
    [dbFields.email]: email
})
    try {
        await dbService.update(Model, user.id, {
            [dbFields.passwordAttempts]: user[dbFields.passwordAttempts] + 1
        });
        console.log("you're blocked, ", user[dbFields.passwordAttempts] )
    } catch (err) {
        logger.error(err);
    }
    throw new error.AccessDenied('Invalid login credentials');
}

My goal is to return the value of user[dbFields.passwordAttempts] to my frontend submitLoginForm function after it makes the login call.
I’m able to console log the value in the backend, but is it possible to return this value to the frontend?
