dexnode - Commandline Utility for Deopt Explorer.

dexnode is a commandline wrapper for the NodeJS executable (node) designed to simplify the process of launching Node with the necessary arguments required to produce a log that can be consumed by Deopt Explorer. When launched, dexnode will attempt to determine the correct logging and tracing options based on the detected version of NodeJS.

Installation

npm install --global dexnode

Examples

# NodeJS (via global install)
dexnode myscript.js

# NodeJS (via `npm exec`)
npm exec dexnode myscript.js

# Deno (via `deno run`)
deno run -A npm:dexnode myscript.js
