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

ctranslate2

Native Node.js host package for CTranslate2.

This package is intentionally narrow:

  • owns the .node binary surface
  • exposes a minimal translation API
  • does not integrate with OpenSpecUI translation engine selection
  • does not download models
  • does not own OpenSpecUI-specific engine semantics

The current native host loads a CT2 model directory and translates plain strings through Ct2Translator#translateBatch.

Higher-level translation integration lives in @openspecui/local-ct2-translator.

Supported Native Targets

The published package currently ships native addons for the targets declared in napi.config.json:

  • linux-x64-gnu
  • win32-x64-msvc
  • darwin-x64
  • darwin-arm64

index.js enforces this support matrix before it loads the generated NAPI binding. If a new target is added, update napi.config.json and the release automation together so the published tarball still contains every declared ct2.*.node artifact.

Smoke Test

Use a local CT2 model directory that contains the required artifacts:

  • config.json
  • model.bin
  • shared_vocabulary.json
  • source.spm
  • target.spm

Then run:

OPENSPECUI_CT2_MODEL_PATH=/path/to/model-dir \
node packages/ct2-engine/scripts/smoke.ts

The script prints JSON translation results and is the fastest way to verify that the native addon, tokenizer loading, and model directory are all working together.
