You can send your logs in JSON format with tail plugins and using log collectoros. [Sample for fluentbit](https://docs.fluentbit.io/manual/input/tail)

For error logs you can get node process errors and pass it to your log collectors.

client.connect(5170, '127.0.0.1', () => {
log('Application connected to fluent bit');
});

process.setUncaughtExceptionCaptureCallback((err) => {
client.write(JSON.stringify({
type: 'error',
process_id: process.pid,
errno: err.errno,
code: err.code,
message: err.message,
