Introduction

Health Tracker is a personal health tracking application built with Leptos and Axum.

The problem

Health data is scattered across apps, devices, and spreadsheets. You want a single place to track your metrics, but existing tools are either too complex or too rigid.

The solution

A self-hosted web application that lets you log, visualize, and analyze your health data on your own terms. Built with Rust for performance and reliability, with a responsive Leptos frontend.

How it works

Health Tracker uses SSR + hydration for fast initial loads and smooth client-side interactivity:

┌─────────────┐     ┌──────────────┐     ┌─────────────┐
│   Browser   │────▶│  Axum Server │────▶│   SQLite    │
│  (Leptos)   │◀────│  (SSR + API) │◀────│  (Storage)  │
└─────────────┘     └──────────────┘     └─────────────┘

Key technologies

Architecture

Single-crate workspace with feature-gated compilation:

• src/main.rs — Axum server entry (ssr feature)
• src/lib.rs — WASM hydration entry (hydrate feature)
• src/app.rs — Shared components and routes
• src/api/mod.rs — Leptos #[server] functions for UI-driven data flow
• src/server/api/ — REST API for external consumers
• src/shared/ — Framework-agnostic domain types and validation
• migrations/ — SQLx migration files
