# Building from Source

DMRHub can be built using the Makefile or manually.

## Prerequisites

- [Go](https://go.dev/doc/install) (see `go.mod` for the minimum version)
- [Node.js](https://nodejs.org/en/download/) (for the frontend)
- Make sure `$GOPATH/bin` is in your `$PATH`

## With Make

```bash
make build
```

The binary is output to `bin/DMRHub`.

## Manually

1. **Generate Go code** (MessagePack serializers, embedded frontend):

   ```bash
   go generate ./...
   ```

1. **Build the binary:**

   ```bash
   CGO_ENABLED=0 go build -o bin/DMRHub
   ```

## Running Tests

```bash
# Run all tests
make test

# Run tests with coverage
make coverage

# Lint
make lint
```

Tests run with `CGO_ENABLED=0` and parallelism limited to 2.

## Frontend Development

```bash
cd internal/http/frontend
npm ci
npm run dev          # Vite dev server
npm run test:unit    # Vitest unit tests
npm run lint         # ESLint
```
