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 🙏

Blueprint framework core — contract resolution and validation

npm version license

Pre-release: This package is at 0.x. Until 1.0.0, minor versions may include breaking changes. Pin your version if stability matters.

What It Does

blueprint-core is the domain-agnostic runtime library underlying the Blueprint toolkit. It provides the core primitives used by blueprint-cli and blueprint-mock-server. Most consumers will use those packages rather than importing blueprint-core directly.

Resolution

| Feature | Description | |---------|-------------| | Overlay application | Applies overlay actions to base specs — adding, updating, or removing fields | | RPC endpoint generation | Adds RPC action paths to OpenAPI specs derived from state machine action definitions | | Composition endpoints | Adds endpoints whose responses are composed from fields across multiple resource schemas | | Cross-domain relationships | Expands foreign key fields into linked or embedded related resources on response schemas | | Environment filtering | Removes contract elements not tagged for the target deployment environment | | Placeholder substitution | Replaces ${VAR} strings in contracts with values from an env file |

Validation

| Feature | Description | |---------|-------------| | OpenAPI | Structural correctness and $ref resolution | | Design patterns | List response shapes, pagination parameters, and foreign key annotation requirements | | State machines | Within-file consistency and cross-artifact correctness — referenced fields, enum values, and endpoints | | Examples | Example data accuracy against component schemas |
