Build Node.js backends for BigCommerce apps — Express/Fastify servers, OAuth handling, JWT verification, API proxy, webhook processing, session management, and deployment. Use when building the server-side component of BigCommerce apps.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Node.js Backend for BigCommerce Apps

## Before writing code

**Fetch live docs**:
1. Web-search `site:developer.bigcommerce.com apps guide` for app development patterns
2. Fetch `https://expressjs.com/` or `https://fastify.dev/` for framework docs
3. Web-search `bigcommerce node sample app github` for official sample apps

## App Server Architecture

### Typical Stack

```
BigCommerce Admin (iframe)
    ↓ OAuth flow / Load callback
Your Node.js Server (Express/Fastify)
    ↓ API calls
BigCommerce REST/GraphQL APIs
    ↓ Webhooks
Your Webhook Handler
```

How to install

The exact contents, by fingerprint

mdr add orcaqubits/agentic-commerce-skills-plugins/node-backend@sha256:5a2707cdb2b056c4

The line at the top of this page pins the label git:20260309.786511c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
