MERN is an acronym that stands for MongoDB, Express, React, and Node, the four essential technologies that comprise the stack.
MongoDB is a document storage system.
Express(.js) is a web framework written in Node.js.
React(.js) is a JavaScript framework that runs on the client-side.
Node(.js) is the most popular JavaScript web server.
MERN is one of numerous MEAN stack (MongoDB Express Angular Node) variants in which the typical Angular.js frontend framework is substituted with React.js. MEVN (MongoDB, Express, Vue, Node) is another version, although essentially any frontend JavaScript framework can work.
Express and Node are the components of the middle (application) tier. Node.js is a popular and capable JavaScript server platform, while Express.js is a server-side web framework. Regardless of which form you choose, ME(RVA)N is the best way to work with JavaScript and JSON from start to finish.
