Quick start

First you need to integrate record-stdstreams into your application.

const { record } = require('record-stdstreams');

If you use TypeScript, use the following code instead:

import { record } from 'record-stdstreams';

To capture output call the record function. It returns a stop function. To stop capturing call this function. The result are the captured stdout and stderr streams.

const stop = record();

console.log('foo');
console.error('bar');

const { stdout, stderr } = stop();

console.log(stdout);
// => 'foo\n'

console.log(stderr);
// => 'bar\n'

Suppressing output during recording

To record the std streams, but suppress their output, call record with false as parameter:

const stop = record(false);

console.log('foo');
// => Does not produce any output.

const { stdout } = stop();

console.log(stdout);
// => 'foo\n'
