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

lightship-cli 🛳️

Static linter for HTML — your built output and your dev sources — any framework (Astro, Vite, Next, SvelteKit, Vue, Svelte, Hugo, Jekyll, hand-written static sites…).

Lightship analyzes your .html files, without launching a browser, and fails your build (non-zero exit code) when it finds accessibility, SEO or performance problems. Point it at your build output (dist/, build/, out/, _site/…) for the classic CI check, or run it directly on your .vue/.svelte/.astro/.jsx/.tsx/.html sources so findings land on the code you actually edit, with exact line/column (--mode source; --mode both does both at once and is the default when run with no arguments).

Powered by a Rust core; this npm package ships a prebuilt binary for your platform — no Rust toolchain required.

Install

npm install -g lightship-cli
# or, one-off:
npx lightship-cli dist

Usage

lightship [OPTIONS] [FOLDER]
  • FOLDER — folder to scan recursively (default: auto-detected build output and/or sources).
  • --mode <build|source|both> — what to analyze (default: auto-detected).
  • -q, --quiet — print only the summary line.
  • -h, --help, -V, --version.

Exit code: 0 if no errors, 1 if at least one finding has severity Error.

In CI

- run: npm run build
- run: npx lightship-cli dist   # exits 1 on Error → the job fails

What it checks

| Rule | Severity | Checks | |------|----------|--------| | img-alt | Error | every <img> has an alt attribute | | html-lang | Error | <html> has a non-empty lang | | title-present | Error | a non-empty <title> exists | | duplicate-id | Error | ids are unique | | meta-charset | Warn | <meta charset> is present | | meta-viewport | Warn | responsive <meta name="viewport"> is present | | meta-description | Warn | non-empty <meta name="description"> | | img-dimensions | Warn | every <img> has width and height (avoids CLS) | | a-no-text | Warn | every <a href> has an accessible name |

Supported platforms

Windows / macOS / Linux, on x64 and arm64. The right prebuilt binary is pulled in automatically via npm optionalDependencies.
