Create a readable stream of cryptographically secure random bytes using crypto.randomBytes.
$ npm install --save random-readable
or
$ yarn add random-readable
Output 16 random bytes to stdout
.
const random = require('random-readable');
random.createRandomStream(16).pipe(process.stdout);
import createRandomStream from 'random-readable';
createRandomStream(16).pipe(process.stdout);
const random = require('random-readable');
// outputs infinite data to stdout.
const stream = random.createRandomStream();
stream.pipe(process.stdout);
// stop after 250ms to prevent infinite loop.
setTimeout(() => { stream.destroy(); }, 250);
const random = require('random-readable');
random.createRandomStream(1000)
.on('error', err => {
// emitted error, if occured.
// it is a best practice to listen on error event
// and handle the error.
})
.on('data', data => {
// chunk of random bytes generated.
// you can use the data here,
// such as updating hash value.
})
.on('end', () => {
// no more data will be emitted.
// you can finalize your action here,
// such as finalizing hash value.
})
.pipe(process.stdout); // outputs 1000 random bytes to stdout
size?: number
. Default:Infinity
.- Returns:
stream.Readable
of random bytes.
size
is how many bytes that will be generated by stream. If size is undefined
, or has invalid value such as negative value or NaN
, stream generates infinite random bytes.
