after .write() new values can't be read

[Stavtastic]

Hi,

Adding a user to the lowdb works fine. The registration function works. I see the user in db.json.
db.get('users').push({ email: email, password: hash}).write();

However when trying to access the file in another function, the values retrieved are from an old state of the database. see sample code:

const bcrypt = require('bcrypt');
const low = require('lowdb');
const FileSync = require('lowdb/adapters/FileSync');

module.exports = function(passport){
    let adapter = new FileSync('db.json');
    let db = low(adapter);
    passport.use(
        new LocalStrategy({usernameField: 'email'},(email,password,done)=>{

            let user = db.get('users').find({ email: email }).value();

            if (user == null) {
                return done(null,false,{message:'email not registered'});
            }
            //match passwords
            bcrypt.compare(password,user.password,(err,isMatch)=>{
                if(err) throw err;
                if(isMatch){
                    return done(null,user.email);
                } else{
                    return done(null,false,{message: 'password incorrect'});
                }
            })
        })
    );
    passport.serializeUser(function(user,done) {
        //console.log('serialize: ' + user)
        done(null,user);
    });
    passport.deserializeUser(function(user,done){
        //console.log('deserialize: ' + user)
        // User.findById(id,function(err,user){
        //     done(err,user);
        // })
        return done(null, user)
    })
};

How can I ensure the file sync works over all my .js files and is using the most recent state change.

I solved this issue by moving the code a bit (though I find it a bit hacky to do it this way, if anyone knows a better option, please let me know)

const LocalStrategy = require('passport-local').Strategy;
const bcrypt = require('bcrypt');
const low = require('lowdb');
const FileAsync = require('lowdb/adapters/FileSync');

module.exports = function(passport){
    passport.use(
        new LocalStrategy({usernameField: 'email'},(email,password,done)=>{
            let adapter = new FileAsync('db.json');
            let db = low(adapter);
            let user = db.get('users').find({ email: email }).value();
            //console.log("passport user: " + user.email);
            if (user == null) {
                return done(null,false,{message:'email not registered'});
            }
            //match passwords
            bcrypt.compare(password,user.password,(err,isMatch)=>{
                if(err) throw err;
                if(isMatch){
                    return done(null,user.email);
                } else{
                    return done(null,false,{message: 'password incorrect'});
                }
            })
        })
    );
    passport.serializeUser(function(user,done) {
        console.log('serialize: ' + user)
        done(null,user);
    });
    passport.deserializeUser(function(user,done){
        //console.log('deserialize: ' + user)
        // User.findById(id,function(err,user){
        //     done(err,user);
        // })
        return done(null, user)
    })
};
