1. Problem:Currently, the start command is npm run server && npm run dev. This doesn’t work because the backend (server.js) keeps running and blocks the frontend (vite dev server) from starting. Railway can only run one process at a time in a container.2. Solution Overview:Build the frontend first.Serve the built frontend using the backend.Start only the backend on Railway.3. Step 1: Update package.jsonUpdate the scripts section:"scripts": {"dev": "vite","server": "node server.js","build": "vite build","start": "node server.js"}4. Step 2: Update server.js to serve frontendAdd the following to your backend:import express from "express";import path from "path";import { fileURLToPath } from "url";const __dirname = path.dirname(fileURLToPath(import.meta.url));const app = express();// Serve frontend buildapp.use(express.static(path.join(__dirname, "dist")));app.get("*", (_, res) => {res.sendFile(path.join(__dirname, "dist", "index.html"));});const PORT = process.env.PORT || 3001;app.listen(PORT, () => console.log(`Server running on port ${PORT}`));5. Step 3: Railway SettingsBuild command: npm run buildStart command: npm startMake sure the server listens on process.env.PORT6. Step 4: DeployRun build locally or on Railway.Deploy using the updated start command.The backend will serve the frontend and handle API requests.7. Result:Frontend is built and served from the backend.Railway runs a single process (server.js) and the app works correctly.
