Using PassportJS, how does one pass additional form fields to the local authentication strategy?

Question

I\'m using passportJS and I\'m wanting to supply more than just req.body.username and req.body.password to my authentication strategy (passport-loc

Answer 1

In most common cases we need to provide 2 options for login

• with email
• with mobile

Its simple , we can take common filed username and query $or by two options , i posted following snippets,if some one have have same question .

We can also use 'passReqToCallback' is best option too , thanks @Jared Hanson

passport.use(new LocalStrategy({
    usernameField: 'username', passReqToCallback: true
}, async (req, username, password, done) => {
    try {
        //find user with email or mobile
        const user = await Users.findOne({ $or: [{ email: username }, { mobile: username }] });

        //if not handle it
        if (!user) {
            return done(null, {
                status: false,
                message: "That e-mail address or mobile doesn't have an associated user account. Are you sure you've registered?"
            });
        }

        //match password
        const isMatch = await user.isValidPassword(password);
        debugger
        if (!isMatch) {
            return done(null, {
                status: false,
                message: "Invalid username and password."
            })
        }

        //otherwise return user
        done(null, {
            status: true,
            data: user
        });
    } catch (error) {
        done(error, {
            status: false,
            message: error
        });
    }
}));
