Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

medusa-storefront scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Medusa v2 Storefront with Next.js

Before writing code

Fetch live docs:

  1. Fetch https://docs.medusajs.com/resources/storefront-development for storefront overview
  2. Web-search site:docs.medusajs.com nextjs starter storefront for starter template
  3. Web-search site:docs.medusajs.com JS SDK client setup for Medusa SDK configuration
  4. Web-search site:docs.medusajs.com storefront API reference for Store API endpoints
  5. Web-search site:github.com medusajs nextjs-starter-medusa for latest starter source

Storefront Architecture

Medusa v2 storefronts are headless -- they consume the Store API over HTTP:

Layer Component
Frontend Next.js App (SSR/RSC)
HTTP Client Medusa JS SDK
Backend Medusa Backend (/store/* API routes)
Storage PostgreSQL / Redis

Next.js Starter Structure

Directory Key Files
app/ layout.tsx, page.tsx (homepage)
app/(main)/products/ page.tsx (listing), [handle]/page.tsx (detail)
app/(main)/collections/ [handle]/page.tsx (collection)
app/(main)/cart/, app/(main)/checkout/ Cart page, checkout flow
app/(auth)/, app/account/ Login/register, customer dashboard
lib/ sdk.ts (Medusa client), data/ (fetching), util/
components/ products/, cart/, checkout/, layout/
Root next.config.js, .env.local

JS SDK Client Setup

SDK Installation

The Medusa JS SDK provides typed access to the Store API:

// lib/sdk.ts — Fetch live docs for Medusa SDK initialization
import Medusa from "@medusajs/js-sdk"

export const sdk = new Medusa({
  baseUrl: process.env.NEXT_PUBLIC_MEDUSA_BACKEND_URL!,
  // Fetch live docs for publishableKey and other options
})

Environment Variables

NEXT_PUBLIC_MEDUSA_BACKEND_URL=http://localhost:9000
NEXT_PUBLIC_MEDUSA_PUBLISHABLE_KEY=pk_...

The publishable API key is required for Store API requests and scopes them to a specific sales channel.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
