Where to learn the rest of the stack.

Where I learned my basics. Interactive, sequenced, gets you writing real HTML and CSS in the first ten minutes instead of watching someone else type. It's the resource I always send to anyone who asks me how to start with web development.

ForTotal beginners who want to write code on day one.

The reference manual for the entire web platform. Their 'Learn Web Development' track is the cleanest free path from zero to competent HTML/CSS/JS.

ForAnyone who needs HTML, CSS, or vanilla JavaScript context.

Long-form interactive curriculum. The 'Responsive Web Design' and 'JavaScript Algorithms and Data Structures' certifications cover the prerequisites for being productive in any Shopify codebase.

ForTotal beginners who learn by doing exercises.

The deepest free JavaScript book online. Heavier than MDN's tutorials, more thorough than most paid courses. The 'closure', 'async', and 'this' chapters are gold.

ForPeople who already know basic JS and want to actually understand it.

Google's modern, opinionated guides on CSS, accessibility, performance, and progressive enhancement. The CSS series is especially good for understanding the cascade beyond utility classes.

ForDevs who want production-grade web fundamentals.

I use this one a lot. The format is unique: the video IS an editable code editor. You pause the lecture, hit edit, change the actual code, run it, see the result. It's the closest thing to pair-programming with the instructor. Their React and JavaScript courses are top tier.

ForAnyone who learns better by doing than by watching.

React's own docs, rebuilt from scratch in 2023. The 'Quick Start' walks you through state, effects, and hooks in an hour. Best in class.

ForAnyone who knows JS and wants to understand React from first principles.

Interactive course straight from the Next.js team. Free, hands-on, covers the App Router, server components, and data fetching. learnshopify.dev itself runs on Next.js.

ForReact devs ready for a full-stack framework.

Shopify's React-based storefront framework. Worth knowing exists; not where most agencies are placing their bets in 2026, but increasingly relevant for new headless builds.

ForReact-fluent devs going headless or working with enterprise merchants.

If you're heading toward Shopify apps and need real backend chops, this is what I'd send you. Gamified backend curriculum in Python and Go, covers HTTP servers, databases, APIs, the works. Built by people who actually ship.

ForFrontend devs ready to learn server-side properly.

The official reference for Liquid, themes, the Storefront API, the Admin API, Functions, and Hydrogen. The most authoritative single source. Bookmark it, search it every day, never feel bad for not memorizing.

ForEvery Shopify dev, all the time.

Shopify's design system for Admin-side apps. If you're building an embedded app, your UI lives inside Polaris. Read the principles before you reach for the components.

ForAnyone building a Shopify app (not a theme).

An interactive GraphQL explorer for your store's Admin API. The fastest way to understand the object graph and prototype queries before writing code. Essential for the Apps and Admin module work.

ForAnyone working with the Admin API or building integrations.

The complete Liquid reference: filters, tags, objects. The validators in learnshopify.dev are built against this; if a filter isn't documented here, it doesn't exist in Shopify, no matter what AI tells you.

ForEvery theme developer.

(The site you're on.) Interactive, production-focused training that pairs with the docs above. Write real Liquid in the browser, get validated against production-grade patterns, learn the judgment work AI can't do for you. Free during the beta.

ForDevs who can already write a for loop and want the senior-Shopify mindset.

The command-line tool for running a local theme dev server, pulling and pushing themes, scaffolding apps. The first lesson on learnshopify.dev teaches you this; install it before lesson 1.

ForEvery Shopify dev.

The default editor for a reason. Pair it with the Shopify Liquid extension by Shopify itself for proper syntax highlighting and theme-check integration.

ForAnyone without a strong existing preference.

A fork of VS Code with built-in AI. The natural editor for the modern Shopify workflow where you review and direct AI-generated Liquid instead of writing every line yourself. Optional, but worth trying.

ForDevs who already use AI tools daily.

The official forum for Shopify devs and Partners. Storefront and theme questions get answered by Shopify engineers in some threads. Lurk first, contribute, then post your own questions.

ForAll Shopify developers.

Official Shopify Devs channel. Conference talks, deep-dive tutorials, framework releases. Good for catching what's changing in the platform.

ForAnyone who learns from video.
