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 🙏

@amboras-dev/meta-shops-checkout

Storefront half of the Facebook & Instagram Shop plugin (facebook-instagram-shop).

When a shopper checks out from a Meta Shop configured with "Checkout on another website", Meta sends them to a deep-link on the merchant's storefront:

https://store.example.com/checkout?products=variant_x:4,variant_y:2&coupon=SAVE10&cart_origin=meta_shops

This package exports a single rootProviders slot component, MetaShopsCheckoutProvider, that:

  1. Detects the deep-link (only on the checkout path, only when cart_origin=meta_shops).
  2. Builds a fresh cart with exactly the items Meta sent (variantId:qty). The retailer_id Meta returns is the Medusa variant id, so it maps straight to createLineItem.
  3. Applies the coupon as a cart promotion (a bad coupon is skipped, not fatal).
  4. Makes it the storefront's active cart (localStorage.medusa_cart_id + invalidates the shared ['cart'] query) and strips the URL params.

It is idempotency-guarded (a refresh won't re-add items) and fully inert on every other page/URL.

What it does NOT do

Payment-session initialization is left to the storefront's useCheckout, which auto-initializes it once the shopper provides a shipping address + method — Medusa ties the payment amount to shipping, and Meta does not send an address, so payment cannot (and should not) be pre-initialized.

Installation

Installed automatically by the Amboras plugin pipeline as part of the facebook-instagram-shop plugin (it is the manifest's npm_package). It is a Class A integration — declarative rootProviders binding, no storefront source edits.
