Developers have always valued the ability to build their applications on integrated stacks of foundational technology. By using a set of standardized building blocks, they can spend more time working on applications that differentiate the business, rather than gluing lots of separate components together.
That’s where these stacks comes in: JSON documents created in your Angular.js/Vue.js/React.js front end can be sent to the Express.js server, where they can be processed and (assuming they’re valid) stored directly in MongoDB for later retrieval.
These stacks can be used in many ways with a cross-platform write-once approach. Since all the components are based on JavaScript and JSON, the integration between the components of the stack is intuitive and straightforward.
Within the JS ecosystem, a particular app will consist of a combination of technologies, called a “stack.” The MEAN, MERN, and MEVN stacks are among the most popular technology stacks that developers use to create websites and mobile applications.
MEAN, MERN, and MEVN are technology stacks that help people create websites and mobile applications. All three include MongoDB, Express.js (hence why each begins with “ME”), and NodeJS.
The primary difference between these stacks can be found in the third letter of each acronym.
MEAN is a JavaScript stack that relies on the use of Angular for its front-end JavaScript framework, meanwhile, the MERN stack relies on React and its ecosystem. Finally, MEVN relies on Vue.js and its ecosystem.
1. MERN (MongoDB, Express, React and NodeJs)
MERN stands for MongoDB, Express, React, Node, after the four key technologies that make up the stack. MERN is one of several variations of the MEAN stack (MongoDB – Express – Angular – Node), where the traditional Angular.js front-end framework is replaced with React.js.
- MongoDB – a nosql database
- Express.js – Node.js web framework
- React.js – front-end JavaScript framework
- Node.js – the premier JavaScript web server
2. MEVN (MongoDB, Express, Vue and NodeJs)
MEVN is again a web stack just like MEAN and MERN though it is relatively new as the front-end technology used in it which is Vue.JS. That is the only difference in MEAN, MERN, MEVN that the front-end technology used in each of these stacks is different.
- MongoDB – a nosql database
- Express.js – Node.js web framework
- Vue.js – front-end JavaScript framework
- Node.js – the premier JavaScript web server
3. MEAN (MongoDB, Express, Angular and NodeJs)
The MEAN stack is a JavaScript-based framework for developing web applications. MEAN is named after MongoDB, Express, Angular, and Node, the four key technologies that make up the layers of the stack.
- MongoDB – a nosql database
- Express.js – Node.js web framework
- Angular.js – front-end JavaScript framework
- Node.js – the premier JavaScript web server
