## The Hook

Shopify App JS handles OAuth so you do not have to think about it.

## What's Good

Session storage, webhook handling, and API client in one package. Works with Express, Koa, or any Node framework. The Remix adapter makes Hydrogen app development smoother.

## The Catch

Node.js only. Some edge cases require diving into implementation details. Version updates can break existing apps.

## Verdict

The foundation every Node Shopify app needs.
