The technology stack is a set of frameworks and tools used to develop a software product. This set of frameworks and tools are very specifically chosen to work together in creating a well-functioning software.
MERN stack is a web development framework. It consists of MongoDB, ExpressJS, ReactJS, and NodeJS as its working components. Here are the details of what each of these components is used for in developing a web application when using MERN stack:
- MongoDB: A document-oriented, No-SQL database used to store the application data.
- NodeJS: The JavaScript runtime environment. It is used to run JavaScript on a machine rather than in a browser.
- ExpressJS: A framework layered on top of NodeJS, used to build the backend of a site using NodeJS functions and structures. Since NodeJS was not developed to make websites but rather run JavaScript on a machine, ExpressJS was developed.
- ReactJS: A library created by Facebook. It is used to build UI components that create the user interface of the single page web application.
