How to create a login override plugin

library.js

var	passport = module.parent.require('passport'),
	passportLocal = module.parent.require('passport-local').Strategy,
	plugin = {};

plugin.login = function() {
	winston.info('[login] Registering new local login strategy');
	passport.use(new passportLocal({passReqToCallback: true}, plugin.continueLogin));
};

plugin.continueLogin = function(req, username, password, next) {
    // Do your stuff here (query API or SQL db, etc...)
    // If the login was successful:
    next(null, {
        uid: uid
    }, '[[success:authentication-successful]]');

    // But if the login was unsuccessful, pass an error back, like so:
    next(new Error('[[error:invalid-username-or-password]]'));
    
    /*
        You'll probably want to add login in this method to determine whether a login
        refers to an existing user (in which case log in as above), or a new user, in
        which case you'd want to create the user by calling User.create. For your
        convenience, this is how you'd create a user:
      
        var user = module.parent.require('./user');
        
        user.create({
            username: 'someuser',
            email: 'someuser@example.com'
        });
        
        Acceptable values are: username, email, password
    */
};

module.exports = plugin;

plugin.json

{
	"id": "nodebb-plugin-login-mysite",
	"library": "./library.js",
	"hooks": [
		{ "hook": "action:auth.overrideLogin", "method": "login" }

Hi @morwalz, you can do like this (plugin.json):

{
    "library": "./library.js",
    "hooks": [
        {
            "hook": "static:app.load",
            "method": "load"
        },
    ]
}

the library.js

exports.load = function (params, callback) {
    params.router && params.router.use(function autoLogin(req, res, next) {
        if (req.uid) { // already login, passed
            return next();
        }
        if (req.url.startsWith('/login')) {          // the old login path
            res.redirect('/auth/examsbook');   // the new login path
        }
    });
    callback && callback();
};
