rn-logs cli

Use rn-logs to read React Native Metro logs via CDP without MCP overhead. Default output is plain text and safe for non-interactive agent runs.

When to use

You need live Metro logs from a running RN app
You want low-context, plain text log output

Installation

bash

npm install -g rn-logs-cli

bash

bun add -g rn-logs-cli

Then verify:

bash

rn-logs --help

Requirements

rn-logs is installed and available in PATH
Metro is running
App is running on a simulator or device

Core workflow

bash

# 1. List connected apps
rn-logs apps

# 2. Stream logs
rn-logs logs --app "<id|name>"

# 3. Snapshot logs
rn-logs logs --app "<id|name>" --limit 50

Command options

bash

# Changing default port or host
rn-logs "[command]" --host "<host>"    # Metro host (default: localhost)
rn-logs "[command]" --port "<port>"    # Metro port (default: 8081)

rn-logs help

Non-interactive mode

When multiple apps are connected, you must pass --app.
Output is plain text for agent-friendly consumption.

Common failures

metro not reachable -> start Metro or fix host/port
no apps connected -> run app on simulator or device
multiple apps connected -> pass --app
