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

The OpenRPC Specification Repository

Purpose of this Repository

This is a repository that contains the OpenRPC specification, and the tooling to build, maintain, and release the specification.

Latest OpenRPC Specification

The latest version of the specification may be found here.

Previous Versions of the Specification

All versions of the specification can be found on the Github releases page.

You may also access specific versions of the spec by appending the version to the spec url as follows:

https://spec.open-rpc.org/1.0.0

Announcement Recent Change

The OpenRPC specification is now packaged and deployed as @open-rpc/spec, and it includes versioned historical schemas. This allows downstream tooling and SDKs to pull specific schema versions directly from the published package.

Examples:

  • @open-rpc/spec/1_3/schema.json
  • @open-rpc/spec/1_4/schema.json

Regex Change (starting 1.4)

Starting with the 1.4.x schema line, the openrpc constraint moves from explicit patch-level enumeration to a regex-based version-line constraint. This means 1.4.x is validated as a compatibility line instead of requiring each patch version to be listed.

ENUM Change

Historically, schema compatibility across versions was not always explicit. To clarify behavior boundaries, version ENUMs are now treated as strict compatibility declarations: a spec version appears only when that schema behavior set explicitly supports it.

These changes are not intended to break existing valid documents, but they make version/behavior differences explicit and machine-checkable for tooling.

Contributing

How to contribute, build and release are outlined in CONTRIBUTING.md, BUILDING.md and RELEASING.md respectively. Commits in this repository follow the CONVENTIONAL_COMMITS.md specification.
