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

In addition, if you want to read the article how to create dynamic sidebar menu in adminLTE and PHP, 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

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)

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

      {
      session_store.sidebar = result;
      session_store.is_login = true;
