Require is not defined when running in node.js

Question

I'm trying to access the Strava API, but terminal is showing

ReferenceError: require is not defined
at file:///Users/Me/directory/code.js:1:10
at ModuleJob.run (internal/modules/esm/module_job.js:152:23)
at async Loader.import (internal/modules/esm/loader.js:166:24)
at async Object.loadESM (internal/process/esm_loader.js:68:5)

when I try to run the code from their website in terminal.

I've researched it, and it says that it's because I'm running it on a browser, but I don't think I am. I commented out all of the code so the only line was

var StravaApiV3 = require('strava_api_v3');

and the error still keeps showing up. I'm just running it with "cd directory" and then node code.js (the names of the directory and code have been changed for clarity), so I have no clue why it isn't working. Is the one line of code somehow going to a browser? I'm running it with MacOS Big Sur, if that changes anything.

Here's the rest of the code that Strava has on their website, if you need it:

    var StravaApiV3 = require('strava_api_v3');
var defaultClient = StravaApiV3.ApiClient.instance;

// Configure OAuth2 access token for authorization: strava_oauth
var strava_oauth = defaultClient.authentications['strava_oauth'];
strava_oauth.accessToken = "YOUR ACCESS TOKEN"

var api = new StravaApiV3.ActivitiesApi()

var id = 789; // {Long} The identifier of the activity.

var opts = { 
  'includeAllEfforts': true // {Boolean} To include all segments efforts.
};

var callback = function(error, data, response) {
  if (error) {
    console.error(error);
  } else {
    console.log('API called successfully. Returned data: ' + data);
  }
};
api.getActivityById(id, opts, callback);

TL;DR this code is giving me the "require is not defined" error even though I'm running it with node.js

EDITS:

-When I run a dummy require (it's just var fs = require('fs');) in the same directory, it still gives the same error

-My package.json for the directory is

    {
  "name": "stravatest",
  "version": "1.0.0",
  "description": "description",
  "main": "stravatest.js",
  "type":"module",
  "scripts": {
    "test": "test"
  },
  "repository": {
    "type": "git",
    "url": "url"
  },
  "keywords": [
    "keyword"
  ],
  "author": "author",
  "license": "ISC"
}

What's in your package.json and what is the extension of the file you're running? — D. Pardal

Create a new file test.js in that file put one single line of code var fs = require('fs');. Run that file with node node test.js. If it errors, post that info along with your nodejs version. If it doesn't error, something is wrong with your other file. — Jared Smith

I don't see any public modules called strava_api_v3, so can't test if there's a bug in that code (I assume it's a private module?). There are public modules strava and strava-v3 that may work. — user5774952

@Liam - I don't think the OP is actually trying to run anything in a browser so your guidance so far does not seem to apply to running in plain nodejs. — jfriend00

Can you update the error message in your question with the full stack trace? — user5774952

Remove "type": "module" from your package.json. This tells Node you're using ESM rather than CJS, but that's not what you want to be doing (unless you do, in which case you should use the .mjs extension and use import instead of require.

But how exactly are you running the project? You should add a "start" script in your package.json with the following command: node stravatest.js. Then in your terminal run npm start and it should work.

Also, as Zac Anger says, remember to remove the "type": "module" line in your package.json. Otherwise you will see an error.
