為什麼這個簡單的導出在 nodejs 中給了我錯誤？

我得到了這個example product js文件，我正在導出它並在node routes

let products = [
    {
      _id: "1",
      name: "Airpods Wireless Bluetooth Headphones",
    },
    {
      _id: "2",
      name: "iPhone 11 Pro 256GB Memory",
    },
    {
      _id: "3",
      name: "Cannon EOS 80D DSLR Camera",
    },
  ];
  
  export default products

我正在像這樣在 server.js 中獲取這些數據

const products = require('./data/products')

const app = express()

app.get('/', (req, res) => {
    res.json('api running')
})

app.get('/api/products', (req, res) => {
    res.json(products)
})


app.get("/api/products/:id", (req, res) => {
    const product = products.filter(p => p._id === req.params.id);
     res.json(product);
});

但是每當我嘗試運行服務器時，都會出現此錯誤Unexpected token 'export'。為什麼這個簡單的導出給我錯誤？
