Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@hotrepl/cli

npm license

Command-line interface for HotRepl. Talk to a running Unity game from your shell — eval C#, invoke typed commands, inspect the journal, stream watch frames, read artifacts.

Requirements

  • A Unity game running the HotRepl plugin (BepInEx/Mono) or mod (MelonLoader/IL2CPP). The plugin opens ws://127.0.0.1:18590 by default.
  • Node (the published binary uses #!/usr/bin/env node).

Run it without installing

bunx @hotrepl/cli info               # or: npx -y @hotrepl/cli info
bunx @hotrepl/cli eval 'UnityEngine.Application.productName'

Install globally

bun add -g @hotrepl/cli              # or: npm install -g @hotrepl/cli
hotrepl info

Commands

hotrepl info                     # handshake summary
hotrepl wait                     # block until backend is reachable
hotrepl doctor                   # quick self-check
hotrepl eval '<C# expr>'         # evaluate C# on the game's main thread
hotrepl reset                    # reset evaluator state
hotrepl complete '<prefix>' [N]  # completions for partial C#
hotrepl run <name> '<json args>' # invoke a typed command
hotrepl describe <name>          # show a command's schema
hotrepl artifacts read <ref>     # read and verify an artifact
hotrepl journal [--limit N]      # recent eval/command history
hotrepl watch '<C# expr>'        # stream frame-by-frame values

Global flags: --format text|json|jsonl, --json (alias), --jsonl (alias), --url ws://host:port, --limit N.

Environment

| Variable | Effect | | ------------- | --------------------------------------------- | | HOTREPL_URL | Backend URL (default ws://127.0.0.1:18590). |
