Passport-Local Mongoose is a Mongoose plugin that simplifies username creation and password login with Passport.

This module auto-generates salt and hash fields, you don’t require to hash the password with this crypto module, the passport-local-mongoose does this for you.Whenever a user simply hashes their password and if there are two users in the database that have the same password, they will end up having the same hash.

Now, if any one of these passwords gets hacked then the hacker can reach each account that uses the same password because users with identical passwords have the same hash fields.Here are few steps, you can follow for authentication:Create a Directory StructureCreate a Model/User.js File Configuring Passport/Passport-Local in App.jsCreation of the Route/User.js FileRead more here - Nodejs Authentication With Passport JS and Passport Local Mongoose

The unmatched performance, high scalability, real-time app development, single codebase, data streaming services, and event-driven, non-blocking I/O model have compelled from large enterprises to SMBs to build or re-engineer the apps using Node.js technology.

Going ahead, it offers a mechanism to add additional request processing “middleware” in the request handling chain at any point which provides flexibility to the developers to create compatible middleware packages that address the development problems.

With velocity testing tools, the code testing starts as soon as it’s written, and the green or red dots indicate the testing results.

Besides, chai’s assertion can be extended to new context through plugins, and the developers can build their own plugins or use the existing plugin pattern.

Leveraging CMS to build complex web applications saves a lot of development time and efforts as the readymade plugins don’t require developers to code from the scratch for building and deploying functionalities.

This makes keystone the best fit for building full-fledged, high performant, and dynamic applications under tight deadlines.

Both NodeJS and AngularJS are widely used and open source JavaScript-based technologies.

AngularJS is a JavaScript framework, whereas NodeJS is a cross-platform runtime environment.As a client-side JavaScript framework, AngularJS Angular enables developers to create dynamic web applications based on model-view-controller (MVC) architectural pattern and using HTML as a template language.At the same time, NodeJS helps programmers to build scalable server-side applications by using JavaScript as a server-side programming language.

Hence, NodeJS and AngularJS differ from each other in the category of architecture, functionality, performance, and usage.To get in-Depth knowledge on Nodejs you can enroll for a live demo on Nodejs Online TrainingNodeJS Vs AngularJS: Understanding Important Differences Between NodeJS And AngularJSCore ArchitectureAngularJS was developed by Google as a web application development framework.

It was written in a number of programming languages — JavaScript, C, and C++.Take your career to new heights of success with Angularjs Online TrainingWeb FrameworkUnlike NodeJS, AngularJS is a web framework.

But they have an option to choose from a wide range of NodeJS-based frameworks — Socket.io, Hapi.js, Meteor.js, Express.js, and Sails.js.InstallationThe developers can write NodeJS applications in JavaScript.

They can embed the AngularJS files in the code base just like other JavaScript files.Important FeaturesBoth NodeJS and AngularJS support MVC architectural pattern.

NodeJS is an open source, server-side script.

JavaScript has many engines and spider monkey is the first JavaScript engine.

It was developed by Netscape.

After some years chrome has developed a V8 engine which runs on the top of Google’s open-source scripting engine V8.

It's very fast, lightweight and efficient.NodeJS uses the asynchronous mode of operation, event-driven Input/output rather than using the threads for each process and it is a cross-platform JavaScript run-time environment that executes JavaScript code to run on the server.Why Node JS?Node.js uses JavaScript for creating server side applications or we can also use any other languages that can be compiled to JavaScript (like typescript).

The JavaScript is written in the same way as we are using in any client-side application.

Increasing organizations are getting Chief Digital Officers or someone at CXO level to focus purely on digitization.

The transformation involves two different aspect, one via behavioral/mindset and the other one on the technology ecosystem of the organization.

“At least 40% of all businesses will die in the next 10 years… If they don’t figure out how to change their entire company to accommodate new technologies.” — JOHN CHAMBERS, EXECUTIVE CHAIRMAN, CISCO SYSTEM The tech modernization via CX modernization, tech upgrade and automation would accelerate the transformation from technology perspective and it is high on the checklist for the digital officers.

The major dilemma with tech modernization is about: Rebuild from monolithic to micro services architecture or Build API services on need basis within existing eco system and build portals/mobile apps or Reorient the frontend alone for CX and integrate with existing backend via API servicesThe answer to the above dilemma varies based on the context and current status of the enterprise technology stacks.

“In Today’s era of volatility, there is no other way but to re-invent.

Because nothing else is sustainable, everything else you create, somebody else will replicate.” — JEFF BEZOS, AMAZON FOUNDER Amongst multiple tech stacks, Full Stack JavaScript (JS) has been the pick of flavor for many but again it is subject to the context.
