nodejsHow to pipe streams
You might want to use pipeline() as a better alternative that will properly clean memory after stream processing.
const fs = require('fs');
let input = fs.createReadStream('/var/www/examples/test.txt');
let output = fs.createWriteStream('/tmp/out.txt');
input.pipe(output);ctrl + crequire('fs')library to work with file system | fs.createReadStream(create stream to read data from (file in our case) |
fs.createWriteStreamopen file and create writing stream from it | /var/www/examples/test.txtpath to file to stream read |
/tmp/out.txtpath to file to write stream to | .pipe(pipe |

const fs = require('fs');
let input = fs.createReadStream('/var/www/examples/test.txt');
let output = fs.createWriteStream('/tmp/out.txt');
