Installs MERN Stack Development Server on RHEL Based Systems.

This Blueprint Installs MERN Stack development server on a RHEL Based Systems.

MERN stands for MongoDB, ExpressJS, ReactJS and Nginx web server. This blueprint install all these components on the target system and launches a react development server.

MongoDB MongoDB is a source-available cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas.

Express Express.js, or simply Express, is a back end web application framework for Node.js, released as free and open-source software under the MIT License. It is designed for building web applications and APIs.

Pre-Blueprint Attune setup
  1. On the Inputs tab, create a Linux node for the host you wish to install the stack on.
  2. On the Inputs tab, create Linux credentials to connect to the host you wish to install the stack on.
Blueprint Steps
  1. Install NodeJS and NPM for dependency management.
  2. Configure MongoDB NoSQL Database.
  3. Install Express.js - a NodeJS framework to build web applications faster.
  4. Install and configure a ReactJS project.
