如何在nodemon上运行ECMAScript (mjs文件)？

Question

我可以使用--experimental-modules标志在nodejs上运行mjs文件。

node --experimental-modules index.mjs

package.json：

{
    "name": "mjs-tests",
    "version": "1.0.0",
    "description": "",
    "main": "index.js",
    "scripts": {
        "dev": "nodemon index.mjs"
    },
    "keywords": [],
    "author": "",
    "license": "ISC",
    "dependencies": {
        "chalk": "^2.4.2",
        "uuid": "^3.3.2"
    },
    "devDependencies": {
        "nodemon": "^1.19.1"
    }
}

和index.mjs

import http from 'http'

const server = http.createServer((req, res) => {
    res.end('hello')
})

const PORT = 5000
server.listen(PORT, () => {
    console.log(`?‍♀️ Server is running at http://localhost:${PORT}`)
})

但如果我试着

npm run dev

或者(全局安装了nodemon )

nodemon index.mjs

我得到了这个错误

[nodemon] 1.19.1
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*
[nodemon] starting `node index.mjs`
internal/modules/cjs/loader.js:821
  throw new ERR_REQUIRE_ESM(filename);
  ^

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module

那么，如何在nodemon中启用对ECMAScript的支持呢？或者我应该使用像esm这样的东西

Answer 1

当然是yes，你只需要稍微修改一下你的package.json

  "scripts": {
        "dev": "nodemon --experimental-modules index.mjs"
    },
