How to easily create dynamic sidebar menu AdminLTE using node, express and Mysql. I have made several articles about how to create dynamic sidebar menu on adminLTE with the permissions of each user on PHP and MYSQL. For the implementation of the node.js, express.js and jade template engine is slightly different. The menu that can be accessed by each user will be stored in a session.
So that you can follow this tutorial very well, you should read my tutorial how to create a CRUD using node.js express.js, MySQL, and adminLTE from the previous article. Please follow this link

Okay, let’s start the following tutorials:
1. Make sure you have created a MySQL database as node.js (read my previous articles). and sure to make 4 of the table named customer, r_menu, r_menu_sub and user as shown below:
2. Copy the following code to add new data to the table r_menu, r_menu_sub, and user table
r_menu table
1 2 3 4 5 6 7 8 9 10 11 12 13 | DROP TABLE IF EXISTS 'r_menu'; CREATE TABLE 'r_menu' ( 'id_menu' int(2) NOT NULL AUTO_INCREMENT, 'nama_menu' varchar(100) DEFAULT NULL, 'urutan' int(2) DEFAULT NULL, 'icon' varchar(30) DEFAULT NULL, PRIMARY KEY ('id_menu') ) ENGINE=MyISAM AUTO_INCREMENT=8 DEFAULT CHARSET=latin1; insert into 'r_menu'('id_menu','nama_menu','urutan','icon') values (1,'Master',1,'<i class=\"fa fa-bell\"></i> '); insert into 'r_menu'('id_menu','nama_menu','urutan','icon') values (2,'Customer',2,'<i class=\"fa fa-bomb\"></i> '); insert into 'r_menu'('id_menu','nama_menu','urutan','icon') values (3,'Utility',3,'<i class=\"fa fa-cubes\"></i> '); |
r_menu_sub table
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | DROP TABLE IF EXISTS 'r_menu_sub'; CREATE TABLE 'r_menu_sub' ( 'id_sub_menu' int(3) NOT NULL AUTO_INCREMENT, 'nama_sub_menu' varchar(100) DEFAULT NULL, 'id_menu' int(2) DEFAULT NULL, 'urutan_sub_menu' int(2) DEFAULT NULL, 'hak_akses' varchar(30) DEFAULT '4', 'url' varchar(150) DEFAULT '#', 'content_before' varchar(200) DEFAULT NULL, 'content_after' varchar(200) DEFAULT NULL, 'icon' varchar(150) DEFAULT NULL, 'title' varchar(200) DEFAULT NULL, 'target' enum('_self','_blank') DEFAULT '_self', PRIMARY KEY ('id_sub_menu'), KEY 'urutan_sub_menu_index' ('id_menu','urutan_sub_menu') ) ENGINE=MyISAM AUTO_INCREMENT=8 DEFAULT CHARSET=latin1; insert into 'r_menu_sub'('id_sub_menu','nama_sub_menu','id_menu','urutan_sub_menu','hak_akses','url','content_before','content_after','icon','title','target') values (1,'Product',1,3,'2','#','','','<i class=\"fa fa-arrow-right\"></i>','Title please','_self'); insert into 'r_menu_sub'('id_sub_menu','nama_sub_menu','id_menu','urutan_sub_menu','hak_akses','url','content_before','content_after','icon','title','target') values (2,'Brand',1,4,'2','#','','','<i class=\"fa fa-arrow-right\"></i>','Title please','_self'); insert into 'r_menu_sub'('id_sub_menu','nama_sub_menu','id_menu','urutan_sub_menu','hak_akses','url','content_before','content_after','icon','title','target') values (3,'Customer',2,1,'2','#','','','<i class=\"fa fa-arrow-right\"></i>','Title please','_self'); insert into 'r_menu_sub'('id_sub_menu','nama_sub_menu','id_menu','urutan_sub_menu','hak_akses','url','content_before','content_after','icon','title','target') values (4,'Sales',2,2,'2','#','','','<i class=\"fa fa-arrow-right\"></i>','Title please','_self'); insert into 'r_menu_sub'('id_sub_menu','nama_sub_menu','id_menu','urutan_sub_menu','hak_akses','url','content_before','content_after','icon','title','target') values (5,'Backup',3,1,'4','#','','','<i class=\"fa fa-arrow-right\"></i>','Title please','_self'); insert into 'r_menu_sub'('id_sub_menu','nama_sub_menu','id_menu','urutan_sub_menu','hak_akses','url','content_before','content_after','icon','title','target') values (6,'Reference',3,2,'4','#','','','<i class=\"fa fa-arrow-right\"></i>','Title please','_self'); insert into 'r_menu_sub'('id_sub_menu','nama_sub_menu','id_menu','urutan_sub_menu','hak_akses','url','content_before','content_after','icon','title','target') values (7,'bla bla bla',3,3,'4','#','','','<i class=\"fa fa-arrow-right\"></i>','Title please','_self'); |
user table
1 2 3 4 5 6 7 8 9 | DROP TABLE IF EXISTS 'user'; CREATE TABLE 'user' ( 'the_email' varchar(200) DEFAULT NULL, 'the_password' varchar(100) DEFAULT NULL, 'user_menu' varchar(254) DEFAULT NULL ) insert into 'user'('the_email','the_password','user_menu') values ('test@test.com','e10adc3949ba59abbe56e057f20f883e','1,4,6'); |
3. Please download my previous project here, so you no longer need to create from scratch (Since this article is a continuation of the previous article).
4. Make sure your package.json as mine in the picture below so that the application can run properly.
5. Create a new module to check the value of the array (such as in_array function in PHP)
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | module.exports = { in_array : function(needle) { var findNaN = needle !== needle; var indexOf; if(!findNaN && typeof Array.prototype.indexOf === 'function') { indexOf = Array.prototype.indexOf; } else { indexOf = function(needle) { var i = -1, index = -1; for(i = 0; i < this.length; i++) { var item = this[i]; if((findNaN && item !== item) || item === needle) { index = i; break; } } return index; }; } return indexOf.call(this, needle) > -1; } }; |
6. Edit routes index.js on folder routes/index.js and copy the following code
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 | var express = require('express'); var router = express.Router(); var modul = require('../modul/modul'); var session_store; /* GET home page. */ router.get('/', function(req, res, next) { res.render('index', { title: 'Express' }); }); router.get('/login',function(req,res,next){ res.render('main/login',{title:"Login Page"}); }); router.post('/login',function(req,res,next){ session_store=req.session; req.assert('txtEmail', 'Please fill the Username').notEmpty(); req.assert('txtEmail', 'Email not valid').isEmail(); req.assert('txtPassword', 'Please fill the Password').notEmpty(); var errors = req.validationErrors(); if (!errors) { req.getConnection(function(err,connection){ v_pass = req.sanitize( 'txtPassword' ).escape().trim(); v_email = req.sanitize( 'txtEmail' ).escape().trim(); var query = connection.query('select * from user where the_email="'+v_email+'" and the_password=md5("'+v_pass+'")',function(err,rows) { var users=rows; var user_menu = users[0]['user_menu']; var split_user_menu = user_menu.split(','); if(err) { var errornya = ("Error Selecting : %s ",err.code ); console.log(err.code); req.flash('msg_error', errornya); res.redirect('/login'); }else { if(rows.length <=0) { req.flash('msg_error', "Wrong email address or password. Try again."); res.redirect('/login'); } else { var querys = connection.query('SELECT * FROM r_menu',function(err,rows) { if(err) console.log(("Error Selecting : %s ",err )); var result = []; var nil = 0; for(var x in rows) { var id_mn=rows[x].id_menu; var sub_query = connection.query('SELECT * FROM r_menu_sub where id_menu = '+id_mn+" order by urutan_sub_menu asc",function(err,xy) { if(err) console.log(("Error Selecting : %s ",err )); var data_submenu = new Array(); var pjg = xy.length -1; for (var i = 0 ; i <= pjg; i++) { var id_mnus= xy[i]['id_sub_menu']; if(modul.in_array.call(split_user_menu,id_mnus.toString())) { data_submenu.push(xy[i]); } if(i == pjg) { result.push({"name":rows[nil].nama_menu,"icon":rows[nil].icon,"id_menu":rows[nil].id_menu,"sub_menu":data_submenu}); } } if(nil+1 == rows.length) { session_store.sidebar = result; session_store.is_login = true; res.redirect('/customers'); } nil++; }); } }); } } }); }); }else{ errors_detail = " Sory there are error <ul>"; for (i in errors) { error = errors[i]; errors_detail += ' <li>'+error.msg+'</li> '; } errors_detail += "</ul> "; console.log(errors_detail); req.flash('msg_error', errors_detail); res.render('main/login', { }); } }); module.exports = router; |
7. Edit sidebar.jade (views/layout/sidebar.jade) and copy the following code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | aside.main-sidebar section.sidebar .user-panel .pull-left.image img(src='/adminlte/dist/img/user2-160x160.jpg',alt='User Image').img-circle .pull-left.info p Alexander Pierces a(href='#') i.fa.fa-circle.text-success | Online form(action='#',method='get').sidebar-form .input-group input(type='text', name='q',placeholder='Search...').form-control span.input-group-btn button(type='submit', name='search')#search-btn.btn.btn-flat i.fa-fa-search ul.sidebar-menu li.header | Main Navigation for row, index in session_store.sidebar li.treeview a(href='#') != row.icon span |#{row.name} span.pull-right-container i.fa.fa-angle-left.pull-right ul.treeview-menu for y,i in row.sub_menu li a(href='#{y.url}') i.fa.fa-circle-o | #{y.nama_sub_menu} |
8. Add a session variable at each route. For example, I added a session variable on routes customers.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 | var express = require('express'); var router = express.Router(); var authentication_mdl = require('../middlewares/authentication'); var session_store; /* GET Customer page. */ router.get('/',authentication_mdl.is_login, function(req, res, next) { req.getConnection(function(err,connection){ var query = connection.query('SELECT * FROM customer',function(err,rows) { if(err) var errornya = ("Error Selecting : %s ",err ); req.flash('msg_error', errornya); res.render('customer/list',{title:"Customers",data:rows,session_store:req.session}); }); //console.log(query.sql); }); }); router.delete('/delete/(:id)',authentication_mdl.is_login, function(req, res, next) { req.getConnection(function(err,connection){ var customer = { id: req.params.id, } var delete_sql = 'delete from customer where ?'; req.getConnection(function(err,connection){ var query = connection.query(delete_sql, customer, function(err, result){ if(err) { var errors_detail = ("Error Delete : %s ",err); req.flash('msg_error', errors_detail); res.redirect('/customers'); } else{ req.flash('msg_info', 'Delete Customer Success'); res.redirect('/customers'); } }); }); }); }); router.get('/edit/(:id)',authentication_mdl.is_login, function(req,res,next){ req.getConnection(function(err,connection){ var query = connection.query('SELECT * FROM customer where id='+req.params.id,function(err,rows) { if(err) { var errornya = ("Error Selecting : %s ",err ); req.flash('msg_error', errors_detail); res.redirect('/customers'); }else { if(rows.length <=0) { req.flash('msg_error', "Customer can't be find!"); res.redirect('/customers'); } else { console.log(rows); res.render('customer/edit',{title:"Edit ",data:rows[0],session_store:req.session}); } } }); }); }); router.put('/edit/(:id)',authentication_mdl.is_login, function(req,res,next){ req.assert('name', 'Please fill the name').notEmpty(); var errors = req.validationErrors(); if (!errors) { v_name = req.sanitize( 'name' ).escape().trim(); v_email = req.sanitize( 'email' ).escape().trim(); v_address = req.sanitize( 'address' ).escape().trim(); v_phone = req.sanitize( 'phone' ).escape(); var customer = { name: v_name, address: v_address, email: v_email, phone : v_phone } var update_sql = 'update customer SET ? where id = '+req.params.id; req.getConnection(function(err,connection){ var query = connection.query(update_sql, customer, function(err, result){ if(err) { var errors_detail = ("Error Update : %s ",err ); req.flash('msg_error', errors_detail); res.render('customer/edit', { name: req.param('name'), address: req.param('address'), email: req.param('email'), phone: req.param('phone'), }); }else{ req.flash('msg_info', 'Update customer success'); res.redirect('/customers/edit/'+req.params.id); } }); }); }else{ console.log(errors); errors_detail = " Sory there are error <ul>"; for (i in errors) { error = errors[i]; errors_detail += ' <li>'+error.msg+'</li> '; } errors_detail += "</ul> "; req.flash('msg_error', errors_detail); res.redirect('/customers/edit/'+req.params.id); } }); router.post('/add',authentication_mdl.is_login, function(req, res, next) { req.assert('name', 'Please fill the name').notEmpty(); var errors = req.validationErrors(); if (!errors) { v_name = req.sanitize( 'name' ).escape().trim(); v_email = req.sanitize( 'email' ).escape().trim(); v_address = req.sanitize( 'address' ).escape().trim(); v_phone = req.sanitize( 'phone' ).escape(); var customer = { name: v_name, address: v_address, email: v_email, phone : v_phone } var insert_sql = 'INSERT INTO customer SET ?'; req.getConnection(function(err,connection){ var query = connection.query(insert_sql, customer, function(err, result){ if(err) { var errors_detail = ("Error Insert : %s ",err ); req.flash('msg_error', errors_detail); res.render('customer/add-customer', { name: req.param('name'), address: req.param('address'), email: req.param('email'), phone: req.param('phone'), session_store:req.session, }); }else{ req.flash('msg_info', 'Create customer success'); res.redirect('/customers'); } }); }); }else{ console.log(errors); errors_detail = " Sory there are error <ul>"; for (i in errors) { error = errors[i]; errors_detail += ' <li>'+error.msg+'</li> '; } errors_detail += "</ul> "; req.flash('msg_error', errors_detail); res.render('customer/add-customer', { name: req.param('name'), address: req.param('address'), session_store:req.session }); } }); router.get('/add',authentication_mdl.is_login, function(req, res, next) { res.render( 'customer/add-customer', { title: 'Add New Customer', name: '', email: '', phone:'', address:'', session_store:req.session }); }); module.exports = router; |
Save and run the node server with following script
on Linux
DEBUG=expressproject:* npm start
and on windows
set DEBUG=myapp:* & npm start
Open your browser and run http://localhost:3000/login
User: test@test.com
Password: 123456
If successful, your main page will display as shown below:
To try permissions menu, please change user_menu value in user table. The latest value is 1,4,6 change with 1,2,3 and check the result.

Hi, thanks for this very interesting articles
I’ve downloaded your code, install and run without problems
But it does’nt work is i change the main folder from expressproject to myapp
Are there some files to modify inside prj?
About previous message i’ve solved.. my mistake ! but the prj does’nt start with this error:
/Users/mauro/Documents/Webapp prj/expressproject/views/layout/sidebar.jade:20 18| li.header 19| | Main Navigation > 20| for row, index in session_store.sidebar 21| li.treeview 22| a(href=’#’) 23| != row.icon Cannot read property ‘sidebar’ of undefined
TypeError: /Users/mauro/Documents/Webapp prj/expressproject/views/layout/sidebar.jade:20
18| li.header
19| | Main Navigation
> 20| for row, index in session_store.sidebar
21| li.treeview
22| a(href=’#’)
23| != row.icon
Cannot read property ‘sidebar’ of undefined
whats wrong ?
i put all menu and submenu parameter in session with name sidebar.Maybe there are steps left
[php]
if(nil+1 == rows.length)
{
session_store.sidebar = result;
session_store.is_login = true;
res.redirect(‘/customers’);
}
nil++;
[/php]
I hope fix your issue 🙂
Sorry, which file need this new code to add ?
I just found this code on line 75 of index.js
Please check again with your jade template engine writing code. maybe your problem in there. because jade template engine is whitespace-sensitive template.
🙂
i’ve used you original code..
but i’ll try
🙂
