使用硬编码数据的简单 Express.js 后端，交换使用 JSON-file

Question

我正在使用 Express 构建一个简单的后端。一切正常。但是我在 server.js 文件中硬编码了示例数据数组（熊）。我已将熊数据转换为外部 JSON 文件。从这个 JSON-file.

中获取相同的 bears-array 的最佳实践是什么？

我知道我可以在顶部使用 import JSONdata from "./data/DataOfBears.json";。但是如何替换 const bears =[] -section?

const express = require("express");
const app = express();
const port = 5000;

app.get("/api/bears", (req, res) => {
  const bears = [
    {
      id: 1,
      name: "Kodiak bear",
      nameLatin: "Ursus arctos middendorffi",
      description:
        "The Kodiak bear (Ursus arctos middendorffi), also known as the Kodiak brown bear, sometimes the Alaskan brown bear, inhabits the islands of the Kodiak Archipelago in southwest Alaska",
      kingdom: "Animalia",

    },
    {
      id: 2,
      name: "Cinnamon bear",
      nameLatin: "Ursus americanus cinnamomum",

    }
  ];
  res.json(bears);
});

app.listen(port, () => console.log(`Server started, port ${port}`));

Answer 1

可以直接通过express

解析传递JSON文件

const data = require('/path/to/data.json')     
app.get("/api/bears", function (req, res) {
     res.json(data);
})
