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 🙏

@vayo-hq/capture-express

v0.1.1-beta.3

Published

Express middleware: captures real traffic, redacts sensitive fields, hands samples to @vayo-hq/schema-engine. The only Vayo package allowed to import Express types.

Readme

@vayo-hq/capture-express

Express middleware that captures real request/response traffic and turns it into Vayo's inferred schemas — the "zero manual annotation" half of the pipeline (the other half is @vayo-hq/ast's static pass).

const { capture } = require("@vayo-hq/capture-express"); // or `import` for ESM
const { createAdapter } = require("@vayo-hq/db-mongo");

const db = createAdapter(process.env.VAYO_MONGO_URI);
app.use(capture({ db }));

Mount it once, alongside your other middleware, and every request that flows through your app afterward gets folded into that endpoint's request/response schema — no annotations, no comments, no decorators. Sensitive-looking fields (passwords, tokens, credit-card-shaped values) are redacted by key-name pattern before anything is written to your database; pass your own patterns via redact.

Requires Express 4.x (peerDependencies: { express: "^4.19.0" }) — v1 targets Express 4 only; logs a clear warning at startup if it detects a different major version installed, rather than silently producing wrong route paths.

The only Vayo package allowed to import Express types — everything downstream of it is framework-agnostic.

Typically installed and wired via vayo init's printed snippet — see @vayo-hq/cli. Currently in beta: npm install @vayo-hq/capture-express@beta.
