Streams in Node.js

STREAMS IN NODE.JS
In this PPT, we will discuss Streams In Node.js
.One of the key features of Node.js is its
ability to handle streams, which are used to
efficiently process large amounts of data in
real-time. In simple terms, a stream is a
sequence of data that is continuously flowing
from one point to another. In Node.js, streams
are objects that facilitate the efficient
processing of large amounts of data in a
non-blocking and event-driven way.

WHAT ARE STREAMS?
Streams are a way of handling input and output
data in Node.js. They allow data to be read or
written in small chunks, rather than loading the
entire file or data set into memory. This can be
particularly useful for large data sets or
network connections, where loading everything
into memory at once could cause performance
issues. Streams in Node.js can be classified
into four types Readable, Writable, Duplex, and
Transform streams.

WHY ARE STREAMS IMPORTANT?
Streams are important for building efficient and
scalable applications because they allow you to
process large amounts of data in small chunks,
without loading the entire dataset into memory.
This is particularly useful for applications that
deal with large files or real-time data streams.

Piping or chaining streams in Nodejs
Piping or chaining streams is a way to connect
multiple streams together so that the output of
one stream becomes the input of the next stream,
creating a data processing pipeline. This can be
very useful when working with large amounts of
data or when performing complex data
transformations.

ADVANTAGES OF STREAMS

• Memory efficiency Streams can handle large
  amounts of data without requiring a large amount
  of memory.
• Processing speed Streams can start processing
  data immediately, leading to faster processing
  times.
• Modular design Streams are modular and can be
  easily combined and reused to create more complex
  data processing pipelines.
• Backpressure Streams provide built-in
  backpressure mechanisms that prevent data loss or
  resource exhaustion.
• Compatibility Streams are a core part of the
  Node.js API and are widely supported in many
  other programming languages and frameworks.

CONCLUSION

• Streams are a powerful abstraction in Node.js
  that allow data to be read or written in chunks.
  They can be used to handle input and output data
  in a sequential manner, which is particularly
  useful for large data sets or network
  connections.
• Streams can handle input and output data.
• They work in a sequential manner.
• This is useful for large data sets.
• This is also useful for network connections.
