In the src/models/User.ts file, to hash the password using bcrypt, the program is using a Pre Middleware instead of a setter for the password:
/**
* Password hash middleware.
*/
userSchema.pre("save", function save(next) {
const user = this as UserDocument;
if (!user.isModified("password")) { return next(); }
bcrypt.genSalt(10, (err, salt) => {
if (err) { return next(err); }
bcrypt.hash(user.password, salt, undefined, (err: mongoose.Error, hash) => {
if (err) { return next(err); }
user.password = hash;
next();
});
});
});
Just wondering, why is it using a middleware instead of a simple setter? I think this was done this way so that it could use asynchronous bcrypt functions, but correct me if I'm wrong. If this is the reason, this was a really good design choice.
