HnH Map – Nuxt 4 frontend

Nuxt 4 + Tailwind + DaisyUI frontend for the HnH map. Served by the Go backend under /map/.

In dev mode the app is available at the path with baseURL /map/ (e.g. http://localhost:3000/map/). The Go backend must be reachable (directly or via the dev proxy in nuxt.config.ts).

Project structure

pages/ — route pages (e.g. map view, profile, login)
components/ — Vue components
composables/ — shared composition functions
layouts/ — layout components
server/ — Nitro server (if used)
plugins/ — Nuxt plugins
public/gfx/ — static assets (sprites, terrain, etc.)

Requirements

Node.js 20+ (required for build; engines in package.json). Use nvm use if you have .nvmrc, or build via Docker (see below).
npm

Setup

npm install

After upgrading the repo (e.g. to Nuxt 4), run npm install in this directory, then npx nuxt prepare, and verify with npm run build and npm run test.

Development

npm run dev

Then open the app at the path shown (e.g. http://localhost:3000/map/). Ensure the Go backend is running and proxying or serving this app if needed.

Build

npm run build

Static export (for Go http.Dir):

npm run generate

Output is in .output/public. To serve from the existing frontend directory, copy contents to ../frontend after generate, or set nitro.output.dir in nuxt.config.ts and build from the repo root.

Build with Docker (Node 20)

Build requires Node 20+. If your host has an older version (e.g. Node 18), build the frontend in Docker:

docker build -t frontend-nuxt .
docker create --name fn frontend-nuxt
docker cp fn:/frontend ./output-public
docker rm fn
# Copy output-public/* into repo frontend/ and run Go server

Cutover from Vue 2 frontend

Build this app (npm run generate).
Copy .output/public/* into the repo’s frontend directory (or point Go at the Nuxt output directory).
Restart the Go server. The same /map/ routes and API remain.
