How to hash password before saving to db to be compatible with passport module (passport local)

Question

I am using passport-local strategy of passport for authentication. In my express server, I am getting a register post request and I should save password to db for a new user

Answer 1

Why should we go for hashing algorithm, when passport already provided it for us? I mean we just need to plugin the passport-local-mongoose to our user schema like: UserSchema.plugin(passportLocalMongoose) and then, inside the register route we just tell the passportLocalMongoose to do the hashing for us by using:

User.register(new User({username:req.body.username}), req.body.password,function(err,newUser)
{ 
    if(err){
        something
    }else{
        something
    }
)

By doing above we don't need to take care of hashing and it will be done for us. Please correct me if I am wrong or got your question wrong.
