A guide to Salesforce B2C Commerce's Storefront Reference Architecture, or SFRA, a ready-made pattern for storefronts. It uses server-side MVC, reusable cartridges, ISML templates, and client-side JavaScript and styles.

Use it to build controllers and templates, layer custom cartridges over the base storefront, extend existing modules, and create Page Designer components.

It shows how to customise a Salesforce storefront without changing the shared base code, making site-specific changes easier to manage.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00059	$0.01274
Opus 5.5	$0.00024	$0.00510
Sonnet 5.5	$0.00012	$0.00255
Haiku 4.5	$0.00006	$0.00127

Security

Grade A, and why

sf-b2c-sfra 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 1mo 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.

Conceptual Architecture

SFRA Overview

SFRA (Storefront Reference Architecture) is the reference implementation for B2C Commerce storefronts:

Server-side MVC -- Models, Views (ISML), Controllers
Cartridge overlay system -- stack custom cartridges on top of base
module.superModule -- extend base functionality without copying code
Client-side build -- Webpack bundles JS and SCSS
Page Designer -- visual page building with reusable components

Four Key Principles

Principle	Rule
Overlay	Never modify `app_storefront_base` -- create custom cartridges that layer on top
Extend	Use `module.superModule` to inherit and augment, not replace
Hooks	Use commerce hooks for order, payment, and shipping customization
Services	Use the Service Framework for external integrations (payment gateways, ERP)

Cartridge Path Resolution

The cartridge path (configured in Business Manager) resolves files left-to-right. The leftmost cartridge wins.

Example path: app_custom:app_storefront_base

Request for controllers/Product.js checks app_custom first, falls back to app_storefront_base
Templates, models, and scripts follow the same resolution

Cartridge Directory Structure

app_custom/cartridge/
├── controllers/        # Route handlers
├── models/             # Data models
├── scripts/            # Helpers, services
├── templates/          # ISML templates
├── experience/         # Page Designer
└── client/default/     # JS + SCSS source (Webpack)

What this file has done since we first saw it

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.
