MEVN

MEVN is a JavaScript-based full-stack development stack used for building contemporary web applications. It combines MongoDB as the document-oriented database, Express.js as the web application framework for Node.js, Vue.js as the frontend framework, and Node.js as the server runtime. The stack leverages a single programming language—JavaScript—across client and server, which can simplify development and hiring.

In MEVN, the frontend is built with Vue.js, featuring a component-based architecture, reactive data binding, and a virtual DOM. The backend uses Express to handle HTTP requests, middleware, and routing, while MongoDB stores application data, often accessed via an ODM such as Mongoose.

Typical project structure has a separate frontend and backend directory, a RESTful API or GraphQL endpoint, and common patterns for authentication, data validation, and error handling.

Development workflow usually involves tools like Vue CLI or Vite for the client, Node.js and npm or yarn for the server, and a MongoDB instance (local or cloud). Developers connect Vue components to API endpoints and manage state with Vuex or the Composition API.

Nuxt.js can be used to add server-side rendering or static site generation on Vue within a MEVN workflow. MEVN is favored for full-stack JavaScript developers seeking a cohesive stack with a modern frontend.
