Businesses in modern times make use of software or applications that is capable of handling multiple server requests, and are fast in computation of data intensive tasks. The access of the software is provided with secured authentication and authorization system in NodeJS. The reason is because if the users are not authenticated properly and the authorization methods is not introduced in the login system then it might provide opportunity to data hackers, network intruders or cyber criminals to gain unauthorized access to company resource and steal valuable sensitive data of company. This situation can create loss of trust bin minds of consumers, damage reputation of company in market and cause huge financial loss due to non compliance of data security standards like HIPPA, CORPA and DMCA and data protection laws.

What is meant with Authentication in NodeJS?

In simple words authentication means verifying users with username and password. It is a process of providing access to company resources to authenticated users. The password in the login form is hidden and is stored as hashed password rather than plan text. When user enters the password then application converts the input to hashed value. This hashed value is matched with the stored hashed password. If it matches then login is successful allowing the access to company resources through NodeJS applications.

Explain Authorization Systems and how is it different from Authentication?

Authorization system allows us to provide special permissions to the verified users like read write and execute. Unlike authentication where we only focus on verifying users for providing access to company resources, authorization focuses on providing special privilege or setting permission level to the registered and verified users.

Step by step procedure for implementing Authentication and Authorization Systems in Node.js

  • First of all we select the best Authentication Strategy like OAuth, or JWT.
  • Create schema for implementing hashed password to store user credentials
  • Develop intelligent and smart routing using API gateways to handle user registration and authentication processes.
  • Setting up middleware to ensure authentication and authorization of tokens or session cookies.
  • Providing single click logout mechanisms to end all opened sessions.

How to implement Authentication and Authorization Systems in Nodejs applications

Implementing authentication and authorization in NodeJS application is simple and easy. All we need to do is to download NodeJS from official website and install it on our computer. Once that is done download the latest version of npm and install the dependencies required for running NodeJS application smoothly. Deploy the source code in specific folder with secure login authentication and authorization system. The testing of the application must be done before hosting it to the production server for making it go live for public. The authentication system involves implementing authentication methods like encryption of password in hashed format and saving it in the database securely. When user inputs the password the hashed password then application converts it into hashed value which gets matched strongly with exact match of hashed key value pairs. Exact match of key value pairs of hatched password authenticates the user and logins becomes successful. Once the user gets logged in then the company resources can be accessed. It is possible that role based resources must be provided that is why we need to authorize the user with specific privilege or rights to access the company resources. The permission level is also set for the authenticated users.

How to find the best NodeJS developer outsourcing company?

 Selecting the best Node.js developer outsourcing company is crucial for developing highly scalable, robust and secure Nodejs applications that allows employees of organization to perform business tasks efficiently. Nodejs applications must be implemented with robust authentication and authorization system that allows role based login authentication system with special privilege of accessing specific functionality in the application. Here are some ways to find the best NodeJS developer outsourcing company.
