Current Behavior
After running commands which spawn plugin workers on the main process (
nx show project, or any command with the daemon disabled) some users (and notably @FrozenPandaz) experienced terminal issues that resulted in ↑ / ↓ printing escape codes instead of scrolling command history.Expected Behavior
This pull request updates how plugin worker processes handle their input/output streams to improve terminal behavior and debugging capabilities. The main change is switching the worker's stdio from
inherittopipe, and then manually piping the worker's stdout and stderr to the main process. This avoids terminal state issues and enables better debugging.Plugin worker process I/O handling:
stdiooption from'inherit'to'pipe'instartPluginWorker, preventing terminal state issues (such as broken arrow key functionality) after Nx execution.stdoutandstderrto the main process, making it easier to debug and allowing plugins to communicate metrics. Increased the max listener count onprocess.stdoutandprocess.stderrto avoid warnings from multiple listeners.Related Issue(s)
