First time - node server not loading file

Help

Hi @hedkace, I was able to get your app working (try here) with the following changes:

  • move the index.js in api/index.js file
  • remove legacy options from the vercel.json
  • update index.js to correctly handle file paths
import express from "express";
import { parseFile } from "tmx-parser";
import { join } from "path";

// Create Express app
const app = express();
app.use(express.json());

// Helper function to parse TMX file using promises
async function parseTmxFile(filePath) {
  return new Promise((resolve, reject) => {
    parseFile(filePath, (err, loadedMap) => {
      if (err) return reject(err);
      resolve(loadedMap);
    });
  });
}

async function loadMap() {
  try {
    // Use a path relative to the function's directory
    const filePath = join(__dirname, "..", "snowmap1.tmx");
    mapCache = await parseTmxFile(filePath);
    return mapCache;
  } catch (error) {
    console.error("Error loading map:", error);
    throw error;
  }
}

// Define routes
app.get("/test", (req, res) => {
  res.json({ message: "test ok" });
});

app.get("/", async (req, res) => {
  try {
    const map = await loadMap();
    console.log({ map });
    res.json({
      data: { version: map.version, width: map.width, height: map.height },
    });
  } catch (error) {
    res.status(500).json({ success: false, error: error.message });
  }
});

app.listen(3000, () => console.log("Server ready on port 3000."));

module.exports = app;

{
  "rewrites": [{ "source": "/(.*)", "destination": "/api/index" }]
}
