Wildfire Weather Dashboard

🌐 Live Demo

https://wildfire-dashboard-853564661918.us-central1.run.app

Deployed on Google Cloud Run via Docker container. A real-time weather dashboard for high fire-risk California cities, built with ClojureScript and Reagent.

Stack

• ClojureScript — Lisp dialect compiling to JavaScript
• Reagent — ClojureScript wrapper for React
• shadow-cljs — ClojureScript build tooling with hot reload
• Open-Meteo API — free weather data, no API key required

Features

• Live weather data for 8 high fire-risk California cities
• Temperature color-coded by fire risk (blue → green → orange → red)
• Wind speed and compass direction
• Human-readable weather descriptions

Setup

Prerequisites

• Java 21+
• Node.js 20+
• shadow-cljs (npm install -g shadow-cljs)

Run locally

npm install
shadow-cljs watch app

Open http://localhost:8080

Project structure

Key Clojure concepts demonstrated

• r/atom for reactive state management
• swap! for immutable state updates
• Reagent components as plain functions returning Hiccup
• JavaScript interop (js/fetch, js->clj)
• Threading macro -> for data transformation
• doseq for parallel API calls
