get-stdin

What is get-stdin?

The get-stdin package is a simple utility that allows you to easily read stdin as a string or buffer in Node.js. It's useful for command-line tools that need to process input piped to them from the command line.

What are get-stdin's main functionalities?

Read stdin as a string

This feature allows you to read the standard input (stdin) as a string. It returns a promise that resolves with the entire input when the stdin stream ends.

const getStdin = require('get-stdin');

getStdin().then(input => {
  console.log(input);
});

Read stdin as a buffer

This feature allows you to read the standard input (stdin) as a buffer. It returns a promise that resolves with the entire input as a buffer when the stdin stream ends.

const getStdin = require('get-stdin');

getStdin.buffer().then(input => {
  console.log(input);
});

Other packages similar to get-stdin

raw-body

The raw-body package is similar to get-stdin but is more focused on parsing HTTP request bodies and provides more options for limiting size, setting character encoding, and handling errors.

concat-stream

Concat-stream is a writable stream that concatenates all the data from a stream and calls a callback with the result. It can be used in a similar way to get-stdin for collecting stream data, but it is not limited to stdin and does not return a promise.

get-stream

Get-stream is a utility that turns a stream into a string or buffer. It is very similar to get-stdin but works with any stream, not just stdin, and offers more options for handling the stream data.
