process.stdout.write doesn't log in same line (with random line breaks)

[ph55]

What's going wrong?

When using process.stdout.write - output not in the same line. Also the line breaks are random.

How could we reproduce this issue?

// index.js
process.stdout.write('this');
process.stdout.write('should');
process.stdout.write('be');
process.stdout.write('in');
process.stdout.write('one');
process.stdout.write('line');

pm2 start index.js

Output for pm2 logs:

0|index  | this
0|index  | should
0|index  | beinoneline
0|index  | this
0|index  | should
0|index  | beinoneline
0|index  | thisshouldbeinoneline
0|index  | this
0|index  | should
0|index  | bein
0|index  | one
0|index  | line
0|index  | this
0|index  | should
0|index  | beinoneline
0|index  | this
0|index  | shouldbeinone

This issue is still ongoing. Would love a fix.

[jamierobertson1]

Yes, it would be great if it were fixed.

Hi, 2022, 06, 03, and I feel unappreciative for wanting a fix on this, because I have no idea what it would entail. Is there a workaround or something, though?

Ah, howabout just tail -f ~/.pm2/logs/yaddayadda-out.log -n 99 ? seems to work

Hi 2018, welcome to 2022. We have a heritage issue here (far beyond legacy)...

We stopped using pm2 due to this and switched to forever. Honestly I'd love to switch back. Please help.
