NPM: The Node Package Manager
When discussing Node.js, one thing that absolutely should not be not there is built-in sustain for put together administration using the NPM tool that comes by evasion with every Node.js installation. The idea of NPM modules is fairly similar to that of Ruby Gems: a set of openly available, reusable workings, available from side to side easy installation via an online repository, with version and dependency management.
• Some of the most useful NPM modules today are:
4. socket.io and sockjs
6. mongodb and mongojs
Examples of Where Node.js Should Be Used
Node.js is simply working as a server-side proxy where it can handle a huge amount of real-time connections in a non-blocking way. It’s particularly useful for proxying different services with different response times, or collecting data from several source points. An example: consider a server-side application communicates with third-party resources, pull in data from different sources, or storing assets like images and videos to third-party cloud services.
We’ve discuss Node.js from theory to exercise, start with its goals and ambitions, and finish with its sweet spots and pitfalls. When people run into effort with Node, it approximately always boils down to the fact that blocking operation are the root of all evil—99% of Node misuses come as a direct result.
