Get stdin as a string or buffer

npm install get-stdin

// example.js
import getStdin from 'get-stdin';

console.log(await getStdin());
//=> 'unicorns'

$ echo unicorns | node example.js
unicorns

Both methods returns a promise that is resolved when the end event fires on the stdin stream, indicating that there is no more data to be read.

Get stdin as a string.

In a TTY context, a promise that resolves to an empty string is returned.

Get stdin as a Buffer.

In a TTY context, a promise that resolves to an empty Buffer is returned.

You can now accomplish this natively in Node.js using streamConsumers.text() or streamConsumers.buffer():

// example.js
import {text} from 'node:stream/consumers';

console.log(await text(stream))
//=> 'unicorns'

$ echo unicorns | node example.js
unicorns
