The MEAN stack
MEAN stands for several parts of the stack
MongoDB, like other NoSQL databases, lacks a schema. Data is stored and retrieved as JSON documents with several fields inside. So MongoDB is a fantastic alternative for building applications fast when requirements change.
The most popular Node.js web application framework is Express. Express is a primary, programmable web server that may be enhanced with plug-ins. That makes Express light and efficient.
A MEAN app does not have to be provided directly to users via Express, even if this is widespread. Alternatively, you might deploy a reverse proxy web server like Nginx or Apache in front of Express. This allows responsibilities like load balancing to be delegated.
Node.js handles HTTP requests differently than traditional web servers. When a request comes in, the server launches a new thread or even a new process. Thread spawning is faster than forking, but both have overhead. Having many lines causes a system to waste important threads’ scheduling and context switching cycles, slowing down the system and limiting scalability and performance.
