# Start merjs dev server
## Steps
1. Kill any existing process on port 3000:
```bash
lsof -ti :3000 | xargs kill -9 2>/dev/null
```
2. Regenerate routes (in case pages changed):
```bash
zig build codegen
```
3. Build the project:
```bash
zig build
```
4. Start the dev server in the background:
```bash
./zig-out/bin/merjs --port 3000 &
```
5. Wait 2 seconds, then verify the server is listening:
```bash
lsof -i :3000 -sTCP:LISTEN
```
6. Tell the user the server is running at http://localhost:3000
## Flags
- `--port N` — listen on a different port
- `--no-dev` — disable hot reload (SSE watcher)
- `--prerender` — pre-render SSG pages to dist/ and exit
