var stderr = require( '@stdlib/streams-node-stderr' );
Standard error as a Writable stream.
// Write to the terminal...
stderr.write( 'Oh no!', 'utf8' );
// e.g., => 'Oh no!'
stderr
can never be closed and, thus, never emits a 'finish'
event.var proc = require( 'process' );
var stdin = require( '@stdlib/streams-node-stdin' );
var stderr = require( '@stdlib/streams-node-stderr' );
// Set the encoding:
stdin.setEncoding( 'utf8' );
// Create an echo stream:
stdin.pipe( stderr );
// Push data to `stdin`:
stdin.push( 'beep' );
stdin.push( ' ' );
stdin.push( 'boop' );
stdin.push( '\n' );
// End the stream:
stdin.push( null );
// Ensure the process closes:
setTimeout( proc.exit, 1000 );
