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 🙏

sentinel-check

v1.2.2

Published

Security gate for npm, yarn and pnpm: verifies lockfile integrity and tarball hashes before installation

Readme

sentinel-check

Thin npm wrapper for the sentinel CLI published from the sentinel-npm repository.

Use npx --yes sentinel-check ... for one-shot runs with no manual binary setup.

Sentinel supports lockfile verification for npm, Yarn, and pnpm with automatic manager detection.


Quick start

Run directly with npx

# audit only
npx --yes sentinel-check check

# validate lockfile then install dependencies
npx --yes sentinel-check ci

# install one package with verification
npx --yes sentinel-check install [email protected]

Add to package.json scripts (recommended)

Install once in the project and call sentinel from npm scripts:

npm install -D sentinel-check
{
  "scripts": {
    "sentinel:check": "sentinel check",
    "sentinel:ci": "sentinel ci"
  }
}
npm run sentinel:check
npm run sentinel:ci

Need package install with verification? Run it directly:

npx --yes sentinel-check install [email protected]

CI usage

GitHub Actions:

- name: Verify dependency integrity
  run: npx --yes sentinel-check ci

Notes

  1. The wrapper downloads the matching Sentinel release binary on first use.
  2. Downloaded binaries are cached locally.
  3. Integrity is verified using release checksums before execution.
  4. If you see dependency cycles detected, Sentinel found circular dependency chains in the lockfile graph. Verification continues and cycles are reported as a warning. You'll still see the integrity status of all packages. For a safe first recovery step, remove node_modules and rerun npx --yes sentinel-check ci. If lockfile recovery is needed, remove the lockfile and rerun npx --yes sentinel-check ci so Sentinel regenerates it in the guarded flow.
