lanterna-profiler

Overview

Use Lanterna to capture or interpret Node.js profiling reports and turn them into source-backed recommendations.

Core rule: do not guess. Read the report first, then read implicated source files before proposing patches.

Quick Start

Before running Lanterna, detect the command prefix:

command -v lanterna >/dev/null 2>&1 && echo installed || echo use-npx

Use lanterna when installed; otherwise use npx -y @lanterna-profiler/cli. Examples use $LANTERNA as notation only. Replace it with the concrete prefix in every command.

Ask the user for the profiling duration and representative workload before starting any new server capture, unless they already provided them. Do not choose a duration, route, port, credentials, or load scenario silently.
