The Learning Path
A leveled, ordered path from "I've never written code" to shipping real software. Don't skip levels — each one assumes the last. Each level has a goal, the exact tech it introduces, and one free resource to learn it.
If a term is unfamiliar, check the glossary.
Level 0 — Fundamentals
Goal: understand the ground everything else stands on, and get comfortable in the terminal.
Learn: how the web works (browser → server → response), the terminal / CLI basics, Git + GitHub, HTML & CSS, and JavaScript moving into TypeScript.
Resource: The Odin Project — Foundations (free, covers the web, command line, Git, HTML/CSS, and JavaScript end to end).
Level 1 — Ship something
Goal: get a real, live URL on the internet as fast as possible. Nothing motivates like a thing that exists.
Learn: Next.js + Tailwind CSS, then deploy to Cloudflare.
Resource: Next.js Learn course (free, official, builds and deploys a real app).
Level 2 — Make it real
Goal: turn a static page into an app with accounts and saved data.
Learn: Supabase for the database, Clerk for auth, environment variables for your keys, and Zod for forms and validation.
Resource: Supabase — Build a Next.js app (free quickstart connecting a database to your app).
Level 3 — Make it good
Goal: adopt the habits that separate a toy from real software. This is the Universal Toolbelt becoming muscle memory.
Learn: Biome as your formatter + linter, type-check discipline (stop ignoring the red squiggles), Vitest basics, and Sentry for error monitoring.
Resource: Vitest — Getting Started (free, the on-ramp to writing your first tests).
Level 4 — Specialize
Goal: branch toward what you actually want to build. By now the core transfers, so each path is mostly new APIs, not a new language.
Pick a branch:
- Mobile → React Native via Expo — reuse your TypeScript and React on phones.
- AI apps → AI SDK + Claude — add a model call to a web app.
- Backend → Hono — build a standalone API when Next.js routes aren't enough.
Resource: open the domain page for your chosen branch and build one small project end to end.
