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

🧵✨ @rexeus/typeweaver-core

npm version License TypeScript

Typeweaver is a type-safe HTTP API framework built for API-first development with a focus on developer experience. Use typeweaver to specify your HTTP APIs in TypeScript and Zod, and generate clients, validators, routers, and more ✨

📝 Core Package

Core runtime and authoring types for typeweaver. This package provides the HTTP primitives, functional spec helpers, validators, and error types that all generators and plugins build on. Generated code imports these runtime utilities.

📥 Installation

npm install @rexeus/typeweaver-core

💡 How to use

This package is typically consumed by generated code. You also use it when authoring specs via defineSpec, defineOperation, and defineResponse. To get started with generation, see @rexeus/typeweaver.

🔧 What It Provides

  • HTTP primitives: HttpMethod, HttpStatusCode, IHttpRequest, IHttpResponse, ITypedHttpResponse.
  • Spec authoring: defineSpec, defineOperation, defineResponse, defineDerivedResponse — the functional API for declaring your API contracts.
  • Type guards: isTypedHttpResponse for runtime discrimination of typed response objects.
  • Validation: IRequestValidator, IResponseValidator, plus RequestValidationError and ResponseValidationError with structured issues.
  • Utilities: UnknownResponseError for unrecognized responses.

This package does not ship framework adapters. Use plugins like @rexeus/typeweaver-hono or @rexeus/typeweaver-aws-cdk for routers/integrations.
