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

@dcsv-io/d2-problem-details-abstractions

Foundational, zero-dependency package that declares the RFC 7807 ProblemDetails wire-format catalog: the type-URI prefix, the application/problem+json content type, the extension-key wire names, the per-status coarse titles, and the defaultTitleForStatus lookup. Mirrors DcsvIo.D2.ProblemDetails.Abstractions on the .NET side — a leaf package with no outbound dependencies, so any package can import these wire constants without pulling JWT-parsing or route-guard machinery.

Install

pnpm add @dcsv-io/d2-problem-details-abstractions

Public API

| Export | Purpose | | ------------------------------ | ------------------------------------------------------------------------------------------------ | | PROBLEM_TYPE_URI_PREFIX | Base URI for the RFC 7807 type field; the runtime appends the kebab-cased error code. | | PROBLEM_DETAILS_CONTENT_TYPE | RFC 7807 §6.1 MIME type (application/problem+json). | | ProblemDetailsExtensionKeys | as const map of extension-key wire values (ERROR_CODE, MESSAGES, INPUT_ERRORS, CATEGORY, TRACE_ID, CORRELATION_ID). | | ProblemDetailsTitles | as const map of per-status coarse English titles. | | defaultTitleForStatus | Returns the spec-declared title for an HTTP status, or the fallback title. |

The catalog is auto-generated from contracts/problem-details/problem-details.spec.json (generated sources committed). Do not edit src/generated/problem-details.g.ts by hand — changes will be overwritten on the next codegen run.

Dependencies

None. Zero runtime deps — this is a foundational leaf in the dependency graph.

Parity with .NET

Mirrors DcsvIo.D2.ProblemDetails.Abstractions — both declare the spec-derived ProblemDetails wire constants, generated from the same contracts/problem-details/problem-details.spec.json source. Single spec, two emitters, cross-language wire drift structurally impossible. The body-builder that consumes these constants lives one layer up (host-supplied ProblemDetails helpers / JWT middleware) — so the leaf stays free of the result envelope.
