Bankal

Personal kanban board built with Zig + Alpine.js. Uses event sourcing/CQRS.

Features

• Multiple boards
• Drag & drop cards
• Event-sourced persistence (append-only WAL)
• Single binary, embeds frontend

Prerequisites

• Zig 0.15.2 (later might break it)
• Bun (for bundling frontend)

Build & Run

cd static/ && bun install
zig build run

Server runs on localhost:8080. WAL file created automatically.

Deployment

Put behind nginx/caddy with auth or keep on localhost.

API

Simple REST, all JSON:

GET  /api/boards              - list boards
POST /api/boards              - create board
GET  /api/boards/:id/cards    - cards for board
POST /api/cards               - create card
PATCH /api/cards/:id          - update card
PATCH /api/cards/:id/column   - move column
PATCH /api/cards/:id/board    - move board

Architecture

Event sourcing: all changes = events appended to WAL. State is rebuilt from events on startup, which works well enough for small scale.
