Let's say I have a code.js file with the following node.js script:

const axios = require('axios')

async function getData(){
    const response = await axios.get('https://mypage.com.br')
    console.log(response.data)
}
getData()

If I execute it with node code.js it works perfectly fine... However, I'd like to execute it as a module, just so I can use the import statement and use the await command as top level. I'd like to accomplish that without creating a project with a package.json file. My final result would be something like this:

import axios from 'axios' 

const response = await axios.get('https://mypage.com.br')
console.log(response.data)

I haven't managed to make it work with the node command. I know there's a --input-type=module parameter I can use with it. But I've tried running node --input-type=module code.js and I've received the following error:

SyntaxError: Cannot use import statement outside a module

So, that means it's not even being recognized as a module yet. Is it possible to do? Can I execute an isolated script with the command node as a module (while using await on top level)?

CodePudding user response：

Rename the file to name.mjs. This --input-type parameter only applies to STDIN and --eval-d files.

CodePudding user response：

This isn't really possible from the command line. You have only two options for making your file ESM.

1. Edit package.json to have the following key and value.

   {
     "type": "module"
   }
   

2. Change the file extensions from .js to .mjs. The m stands for module.

In conclusion, the flag below doesn't help with changing the type to module.

$ node code.js --input-type=module
