Introduction
Why TaskFlow, how the course is structured, and what you’ll have built by the end. Open →
TaskFlow
Build TaskFlow, a realtime multi-user Kanban board, from an empty repo to a running Docker Compose stack. Along the way you'll work with Rust (Axum), PostgreSQL, Redis, WebSockets, and Astro.
What you’ll build
Section titled “What you’ll build”Setup & Tooling
Install Rust, Node, Docker, and the rest of the toolchain, and scaffold the project. Open →
Database Design
Model boards, columns, and cards in PostgreSQL, with migrations from day one. Open →
Backend Foundations
Stand up the Axum server, routing, config, and error handling. Open →
Authentication
Add signup, login, and session handling so boards belong to real users. Open →
REST API
Build the CRUD endpoints for boards, columns, and cards. Open →
Caching
Speed up reads and protect PostgreSQL with a Redis caching layer. Open →
Realtime
Push live board updates to every connected client over WebSocket. Open →
Frontend
Build the Astro UI that talks to your API and renders the board. Open →
The Kanban Island
Wire up drag-and-drop and realtime sync in an interactive Astro island. Open →
Testing
Cover the backend and frontend with automated tests you can trust. Open →
Docker & Compose
Containerize every service and bring the whole stack up with one command. Open →
Wrap-up
Review what you built and where to take TaskFlow next. Open →
How this guide works
Section titled “How this guide works”Real, copy-pasteable code
Every snippet is real, runnable code you can copy straight into your project — no pseudo-code.
Adapts the Learn Hub courses
Built on patterns from the Learn Hub Rust and Astro courses, applied to one real project end to end.
Bilingual EN / ไทย

You build it by following along
This is a build-along guide: you write the code yourself, step by step, not just read about it.
