findOne: (email) => {
    let userbyemail=[]
    http.get(`http://localhost:8080/auth/user/email/${email}`,resp =>{
        let data = "";
        resp.on("data",chunk =>{
            data += chunk
        })
        req.on('end', () => {
        const user = JSON.parse(data)[0]
        userbyemail = user
        })
    })

    if (userbyemail.email === email){
            return userbyemail;
        }
    return null
},

I want to save the user information to a variable outside of the Http scope, what can i do?
