What is Node.js?
source:( official document )
- Asynchronous and Event-Driven
- High scalability
Asynchronous and Event-Driven:
In node.js, all APIs are asynchronous and non-blocking. It means the API does no wait for response and server the next call. Node.js notification mechanism gets a response when the previous response event triggers.
Node JS uses a single thread model with an event loop. Events manage the request without any blocking. It manages serval requests in a single thread without any interaction.
NPM (Node Package Manager):
NPM by default comes up when we install Node.js. NPM modules consist of a large number of reusable components you can easily install with this version and dependence management.
Some NPM modules are as follows:
- Socket io
How Node.js Works
Some benefits of using node js:
- Better efficiency and overall developer productivity
- Code sharing and reusability
- Speed & performance
- A huge number of tool available free
- Scalable for microservices
- Strong support
- JSON data support
A developer who knows frontend JS can code backend in node.js as well. We also get work done in less time and more effectively.
- Not suitable for heavy calculation on the server-side.
- Callback hell issue
- Immature tool (npm)
- Doesn’t provide scalability
Where Node can be the best solution:
- Chat server/application
- Fast file uploading
- Data streaming
- Add servers
- Stock exchange software
