Devvit Logs

Stream log events from an installed Devvit app for quick debugging. This skill wraps devvit logs and auto-exits after a short window (5 seconds) to avoid hanging on a streaming command.

How It Works

1. Ask the user for the target subreddit (required).
2. Optionally accept an app name and --since=... flag.
3. Run devvit logs and capture output.
4. Exit automatically after the first burst of output or 5 seconds, whichever comes first.

Usage

node ./scripts/devvit-logs.cjs <subreddit> [app-name] [--since=1h]

Script path is relative to this skill’s directory.

Arguments:

• subreddit – Required. Subreddit to stream logs from.
• app-name – Optional. App name if streaming from another folder.
• --since=Xd – Optional. Historical logs window (e.g., --since=30m, --since=1d).

Examples:

node ./scripts/devvit-logs.cjs my-subreddit
node ./scripts/devvit-logs.cjs my-subreddit my-app --since=1h

Output

{
  "ok": true,
  "reason": "timeout",
  "exitCode": null,
  "signal": null,
  "stdout": "=============================== streaming logs for my-app on my-subreddit ================================\n[DEBUG] Dec 8 15:55:23 Action called!",
  "stderr": ""
}

Present Results to User

• If the user did not provide a subreddit, ask for it explicitly.
• Summarize the captured logs (if any) and mention the 5-second capture window.
• If no logs were captured, say so and suggest retrying with activity or --since=....

Troubleshooting

• Devvit CLI not found: Install or ensure devvit is in PATH.
• Not logged in: Run devvit login and try again.
• No logs: Trigger an action in the app or use --since=....
• Permission errors: Confirm the app is installed in the subreddit and you have access.
