Nodejs Express Middleware

Nodejs Express Middleware is a set of middlewares build for Expressjs aimed at:

• Support layout rendering.
• Provide block and slot mechanism to include views in Expressjs (block and slot helper).
• Provide NODE-NTJS script integration (script, scripts, javascripts, stylesheets, and jsloader helper).
• Provide menu builder (menu helper).
• Provide pager builder (pager helper).
• Provide a simple security to Expressjs routes (user helper).

Expressjs Integration

Here is a typical usage in Expressjs app.

// app.js

// security
app.use(require('./lib/security/security')());

// app helpers
app.use(require('./lib/helper/core')());
app.use(require('./lib/helper/menu')());
app.use(require('./lib/helper/pager')());

const { ScriptManager, ScriptAsset } = require('./lib/script');
ScriptManager.addDefault('SemanticUI');
ScriptManager.addAsset(ScriptAsset.STYLESHEET, 'app.css');

// relative from layout
app.slots = {
  mainmenu: {
    view: '../slot/mainmenu'
  }
};

<%# mainmenu.ejs %>

<% menus = {
    branding: {
        type: 'brand',
        title: apptitle,
        logo: '/images/logo.png',
        url: '/'
    },
    tasks: {
        title: 'Tasks',
        class: 'right floated',
        items: {
            about: {
                title: 'About'
            }
        }
    }
} %>
<% if(user.authenticated) {
    Object.assign(menus.tasks.items, {
        divider1: {
            type: 'divider'
        },
        profile: {
            title: 'Profile'
        }
    });
} %>
<%- menu(menus, {mainmenu: true, indentation: 2}) %>
<% script.create('JQuery')
  .useDependencies(['SemanticUI/Dialog/Message'])
  .addMiddle(`
$.tasks = {
    about: function() {
        $.ntdlg.message('task-about', 'About', 'About App Message', $.ntdlg.ICON_INFO);
    },
    profile: function() {
        $.ntdlg.message('task-profile', 'Howdy', 'Welcome User', $.ntdlg.ICON_INFO);
    },
    init: function() {
        var self = this;
        $('.menu-about').on('click', function(e) {
            e.preventDefault();
            self.about();
        });
        $('.menu-profile').on('click', function(e) {
            e.preventDefault();
            self.profile();
        });
    }
}
`).addLast(`
$.tasks.init();
`); %>

Example Usage

Nodejs Express Middleware is heavily used by NODE-SMS-TERMINAL and NODE-SMS-GATEWAY.
