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 🙏

v0.1.0

Published

Performance-first browser RAW runtime for LumaForge.

Readme

@lumaforge/luma-raw-runtime

Browser-local RAW decoding runtime for LumaForge.

This package owns the Luma RAW worker protocol, TypeScript facade, native C++ wrapper, and Emscripten build that produces dist/native/luma_raw.js and dist/native/luma_raw.wasm.

Native Build Policy

The native runtime is rebuilt from pinned upstream source archives. It must not depend on the npm libraw-wasm package, the LibRaw-Wasm repository, or any local baseline artifact path.

Pinned native inputs are recorded in native/sources.lock.json:

| Component | Version | Role | License source | | -------------- | ------- | ---------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- | | LibRaw | 0.22.1 | RAW metadata, thumbnail extraction, and RGB16 decode | THIRD_PARTY_LICENSES/LibRaw-COPYRIGHT.txt, THIRD_PARTY_LICENSES/LibRaw-LICENSE.LGPL.txt, THIRD_PARTY_LICENSES/LibRaw-LICENSE.CDDL.txt | | Little CMS | 2.18 | ICC/color management support linked into LibRaw | THIRD_PARTY_LICENSES/LittleCMS-LICENSE.txt | | Emscripten SDK | 5.0.6 | WebAssembly toolchain | pinned in native/sources.lock.json |

Run:

pnpm --filter @lumaforge/luma-raw-runtime native:fetch
pnpm --filter @lumaforge/luma-raw-runtime build:native
pnpm --filter @lumaforge/luma-raw-runtime native:verify
pnpm --filter @lumaforge/luma-raw-runtime native:verify-baseline

native:verify-baseline is the active guard that prevents reintroducing libraw-wasm, LibRaw-Wasm, BASELINE_ROOT, or local /workspaces/LumaForge build inputs into the package build.

Licensing

The generated native WebAssembly artifacts contain third-party code. Those components are not relicensed by LumaForge:

  • LibRaw is distributed by upstream under LGPL-2.1 or CDDL-1.0 license options.

Keep THIRD_PARTY_NOTICES.md and THIRD_PARTY_LICENSES/ with any redistributed package or native artifact bundle. If upstream native sources are modified, record the patch under native/patches/, keep the original notices intact, and update THIRD_PARTY_NOTICES.md.
