Fetch is not Defined

Question

I'm very new to Javascript and just built my very first bot, I try to run my bot and it WORKS! But when I use the discord command it crashes on Repl.it. I have done npm install node-fetch but that doesn't seem to be working either. Here is the error:

Error [ERR_REQUIRE_ESM]: require() of ES Module /home/runner/myrepl/node_modules/node-fetch/src/index.js from /home/runner/myrepl/index.js not supported.
Instead change the require of /home/runner/myrepl/node_modules/node-fetch/src/index.js in /home/runner/myrepl/index.js to a dynamic import() which is available in all CommonJS modules.

  code: 'ERR_REQUIRE_ESM'
}
repl process died unexpectedly: exit status 1

My Index.js is:

    node-fetch(`https://www.rolimons.com/uaid/` + id).then(res => res.text()).then(res => {
      //// clog(res)

I am SO SO CLOSE to completing my very first bot please help! Any help is appreciated. Thanks!

If this is nodeJs code it won't understand fetch. You'll have to [import something like `node-fetch`](https://www.npmjs.com/package/node-fetch) and use that. Note: the fetch API [is coming to node soon](https://blog.logrocket.com/fetch-api-node-js/). — Andy, Apr 05 '22 at 19:58
@RobinZigmond I have tried that but it keeps saying "Cannot import outside of module" — user18383426, Apr 05 '22 at 20:10
Then try `const fetch = require('node-fetch');` instead of `import` — cachius, Apr 05 '22 at 20:16
Gives a big error: `Error [ERR_REQUIRE_ESM]: require() of ES Module /home/runner/Poisithink/node_modules/node-fetch/src/index.js from /home/runner/Poisithink/index.js not supported. Instead change the require of /home/runner/Poisithink/node_modules/node-fetch/src/index.js in /home/runner/Poisithink/index.js to a dynamic import() which is available in all CommonJS modules` @cachius (There is much more lol) — user18383426, Apr 05 '22 at 20:22
Latest edit constitutes duplicate of [Error: require() of ES modules is not supported when importing node-fetch](https://stackoverflow.com/questions/69041454/error-require-of-es-modules-is-not-supported-when-importing-node-fetch) — esqew, Apr 05 '22 at 20:26

It was hard to find, but after alot of searching I found a way it would work. This worked:

const fetch = (...args) => import('node-fetch').then(({default: fetch}) => fetch(...args));
