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 🙏

c2pa-wasm

The WebAssembly wrapper for c2pa-rs that powers c2pa-web, built with wasm-bindgen. While these bindings can be used directly, most users will prefer the convenience of c2pa-web.

Installation

npm install @contentauth/c2pa-wasm

Development

Prerequisites

Ensure the repo-wide prerequisites (Node.js v22+, NX, and pnpm) are installed. See the top-level README for details.

Then, all of the following prerequisites must be installed before c2pa-wasm can be built:

Rust

Installation instructions

Minimum supported Rust version: 1.88.0.

To install Rust via rustup:

curl https://sh.rustup.rs -sSf | sh

Additionally, the wasm32-unknown-unknown target must be installed:

rustup target add wasm32-unknown-unknown

wasm-bindgen-cli

Documentation

cargo install [email protected]

Important: The version of wasm-bindgen-cli must match the version of the wasm-bindgen dependency in Cargo.toml. A version mismatch will cause build failures with errors like "rust Wasm file schema version: X.X.X, this binary schema version: Y.Y.Y". If you encounter this, check Cargo.toml for the correct version and reinstall the CLI accordingly.

wasm-pack

Documentation

cargo install [email protected]

Building

To build the library:

nx build c2pa-wasm

This will execute the commands defined in the nx-wasm-bindgen executor to produce the final output in the pkg/ directory.

Testing

The library relies on wasm-pack to run its tests. As a general principle, the majority of test coverage will come from c2pa-web's test suite.

To run the tests:

nx test c2pa-wasm
