Integrating an npm module that uses import

[lavolp3]

HI all,

I am trying to write a module around the npm module picnic-api that uses the import function instead of require

import axios from "axios";

This does not work within the Magicmirror environment, I get an error message when I start the mirror.

[13.02.2021 07:21.43.938] [ERROR] /home/pi/MagicMirror/modules/MMM-Picnic/node_modules/picnic-api/index.js:1
import axios from "axios";
^^^^^^

SyntaxError: Cannot use import statement outside a module

Does anyone have a solution for me?
Is there a way to use it or do I need to rewrite the npm module?

@lavolp3 which version of nodejs are you running? import is a feature of es6 modules. You can try to enable it like this https://stackoverflow.com/a/45854500

Thanks for the tip. Upgraded to node.js 14.15 but did not work yet.
Seeing "type": "module in my package.json also did not help.
I will have to have a closer look at the link

@lavolp3 yiu can also use

const ax = require('axios')

in node_helper.js
after npm install axios

@sdetweil that’s not sufficient. There are two more modules imported by the picnic-api module. I could require them all in node_helper but that looks too of much a workaround for me. There should be another way.

@lavolp3 sometimes u get to do things that arent perfect. but get to move on.

@lavolp3

• rename node_helper.js to node_helper.mjs

worked in my test (did not do anything with the imported axios, but mm starts).

[sdetweil]

@karsten13 was node_helper loaded? i doubt it. its optional. so this doesnt help

@sdetweil no :crying_face:

may using esm library is one approach as described e.g. here https://blog.logrocket.com/how-to-use-ecmascript-modules-with-node-js/

@karsten13 in node… but we have a custom environment, that is not node pure…
