24/24 shown
TypeScript: npm i typescript
Annotations, interfaces, unions and narrowing, starting from a plain JavaScript file and a compiler that keeps telling you no. By week three the compiler is on your side.
TypeScript: npm i typescript
Type parameters, constraints and inference, taught with functions you already write. You stop copying `<T>` from Stack Overflow and start knowing where it goes.
TypeScript: npm i zod
Validate responses with Zod, infer types from the schema and let one definition protect the form, the fetch call and the server. No more `as any` at the network edge.
TypeScript: npm i typescript
Conditional, mapped and template literal types, used to build a typed router and an event emitter. For the person who maintains the types everyone else imports.
React: npm i react
JSX, props, state and lists, building a small app piece by piece in TypeScript. You learn what a re-render is before you learn how to avoid one.
React: npm i react
useState, useEffect, useReducer and custom hooks, with the dependency array finally explained. Most of the course is deleting effects that never needed to exist.
React: npm i @radix-ui/react-dialog
Dialogs, menus, tabs and comboboxes that work with a keyboard and a screen reader. You build them by hand once, then learn what Radix and React Aria do for you.
React: npm i react-dom/server
Where code runs, what crosses the boundary, and how Suspense, streaming and server actions change the shape of an app. Taught against React 19 with no framework magic hidden.
Vue: npm i vue
Templates, reactivity, components and single-file components, ending in a small app you put online. Friendly to anyone who knows a bit of HTML and JavaScript.
Vue: npm i vue
ref, reactive, computed and watch, then composables that share logic cleanly across components. With `<script setup>` and TypeScript throughout.
Vue: npm i pinia
Stores, getters, actions and plugins, plus the judgement to keep most state out of a store at all. Two short weeks for a Vue app that has started to sprawl.
Vue: npm i vue
Design tokens, slots, typed props and emits, documentation and a release pipeline. You publish a small library another team could install on Monday.
Next.js & Nuxt: npm i next
Pages, layouts, links, images and metadata in the App Router, then a deploy. A gentle way into frameworks if you can already write a React component.
Next.js & Nuxt: npm i next
Dynamic routes, data fetching, caching and revalidation, and the reasons behind each default. You stop guessing why a page is stale and start choosing when it should be.
Next.js & Nuxt: npm i nuxt
File-based routing, server routes, useFetch, auto-imports and rendering modes. Everything you know from Vue, with a server added and the setup taken away.
Next.js & Nuxt: npm i next
Authentication, observability, performance budgets, security headers and a deploy you can roll back. A five-week course built around one real app going live.
TanStack: npm i @tanstack/react-query
Queries, mutations, caching and loading states, replacing a tangle of useEffect fetches. Short and practical; you need only a little React to keep up.
TanStack: npm i @tanstack/react-table
Sorting, filtering, pagination and virtualised rows on a headless table you style yourself. For anyone whose admin screen currently freezes at a thousand rows.
TanStack: npm i @tanstack/react-router
Typed params, search state in the URL, loaders and code splitting. A wrong link becomes a compile error instead of a 404 in production.
TanStack: npm i @tanstack/react-start
Server functions, streaming SSR, Query and Router working together, deployed to the edge. For developers comfortable with React who want the whole stack typed.
Tooling & testing: npm i vite
Node, pnpm, package.json, Vite, ESLint and Prettier, explained one config file at a time. Two weeks that make every tutorial afterwards easier to follow.
Tooling & testing: npm i vitest
Unit tests, component tests and mocks that test behaviour rather than implementation. You leave with a suite you trust enough to refactor against.
Tooling & testing: npm i @playwright/test
Locators, fixtures, network mocking and visual checks, running in CI on every pull request. The flaky test is the first thing we fix.
Tooling & testing: npm i tsdown
Package exports, dual builds, type declarations, changesets and provenance. You publish something small and correct, and learn why most packages get one of these wrong.
