Backend Framework: Node.js
Popularity
According to a survey with 51,620 responses conducted by Stack Overflow, Node.js
is currently the most popular framework. One of the reasons for Node.js's popularity is that
it runs off of JavaScript. Since JavaScript is common to most web developers, it is easy to
transition from another web technology to Node.js.
Advantages
Node.js has very high performance
Interprets JavaScript using Google's V8 JS engine. Google's V8 JS engine compiles
JS code directly into machine code. This allows the engine to execute the code at very
fast speeds.
Node.js can be hosted almost anywhere
Since Node.js is such a popular backend framework it is supported by many web servers and cloud based
hosting providers without needing to install it.
Node.js can handle requests simultaneously
Node.js performs I/O operations asynchronously, meaning that it saves a lot of memory
and is easier to execute when compared to traditional looping.
Disadvantages
Application Programming Interface for Node.js isn't stable
The Node.js API frequently changes. Sometimes a new API appears and
it will not have backwards compatibility so developers will have to
make changes to their code to ensure their code is compatible with
the latest version of the Node.js API.
Node.js is not efficient in handling CPU-intensive apps
Node.js does not support multi-threaded programming so it is not very good for
performing very long calculations or anything cpu intensive.
Who uses Node.js and for what type of websites?
Node.js is mainly used by backend developers for data-intensive real-time applications that run across various devices.
