I'm building a simple Electron app for MacOS (using React as the frontend). The purpose of the app was to make executing certain terminal commands a lot easier (using child_process.spawn. Primarily I am interested in using the sfdx Salesforce CLI commands.
When I run the app in dev, everything works fine. However when I package the app, the PATH variable gets changed and I'm no longer able to locate the sfdx library. (*note it is still able to find git commands though).
I found a very similar issue here and a bug report in GitHub, both of which recommend the use of the fix-path package. This is where I run into another issue. According to the docs, I should import the package like this:
import fixPath from 'fix-path';
However when I do that inside of my electron.js file I get this error: SyntaxError: Cannot use import statement outside a module. I've seen other resources that use require to bring in the package:
const fixPath = require('fix-path');
But again, when I do that I get this error require() of ES Module not supported.
I tried adding "type": "module" to my package.json file, but that breaks my app as well.
I feel like there is something simple that I am missing here, but can't seem to figure out. I believe that if I could import and use the fix-path package, then this would solve my problems. But if that isn't possible, does anyone know of a way for me to fix the path in my app so that it works in prod?
Thank you in advance!
Some extra details:
The two dependencies I check for are git and sfdx. The following image shows where both of those live on my machine:
And this is the response to the same commands within the packages asar file:
I found a workaround, it looks like fix-path made a move to ESM during the last release. Because I am using CJS modules I just needed to install version 3 of fix-path by running npm install fix-path#3.0.0 --save

I have included (via npm) the twilio/voice-sdk package (v.2.1.0) into a project. When I include the following code (as shown in many examples):
const Device = require('#twilio/voice-sdk').Device;
I get a console error stating:
"Cannot find module 'events' in '#twilio/audioplayer/es5'". I am trying to import this onto the client side, not server.
I get this whether I use require or import.
As an attempt around this, I have also include the node package #twilio/audioplayer, but to no avail. Kind of stuck as to what is going on here.
I am trying to use this on a Wix (or Velo more specifically) project. Hoping to create a dialer that can both answer and instigate phone calls on a site that already exists on that platform.
I have installed both of the above npm packages into my project, but get he above enumerated error.
Any ideas from the Internet?
Additional Information:
If I add the 'require' on the server side I do not get the same error. I was going to try this and then do an async call to the server to get my Device object. However, the Twilio Device SDK package utilizes the Window object, which of course does not exist on the server side.
The #twilio/audioplayer package uses the "events" module. This module is available in Node.js and when applications are bundled with something like Webpack is polyfilled.
I haven't used Velo, but I assume they are bundling differently in a way that doesn't add polyfills for this. I'd recommend installing the events npm module to your project too. That should provide the EventEmitter that the library is using for the browser environment and stop this error.
I had a similar problem, where I can import Device, but cannot construct it. The problem I had was that the bundler (in my case Vite) doesn't have a polyfill to run some functions inside the #twilio/voice-sdk.
The solution in my case was by installing polyfill on Vite.
Here is how:
First, install these packages:
npm i #esbuild-plugins/node-globals-polyfill #esbuild-plugins/node-modules-polyfill --save-dev
Then add the polyfill config to your vite.config.js. Here is link of the code: https://medium.com/#ftaioli/using-node-js-builtin-modules-with-vite-6194737c2cd2.
Because I use React, I still need to add plugins: [react()] inside the polyfill config. So it becomes something like:
export default defineConfig({
plugins: [react()],
// rest of the polyfill config
})
Now you can do:
import { Device } from "#twilio/voice-sdk";
new Device(token);
I tried so but I have a 'require is not defined' error. I can't find information about that, can someone enlighten the noob in me please?
It's possible, but you have to be careful. Trying to require() a package means that node will try to locate its files in your file system. A chrome extension only has access to the files you declare in the manifest, not your filesystem.
To get around this, use a module bundler like Webpack, which will generate a single javascript file containing all code for all packages included through require(). You will have to generate a separate module for each component of your chrome extension (e.g. one for the background page, one for content scripts, one for the popup) and declare each generated module in your manifest.
To avoid trying to setup your build system to make using require() possible, I suggest starting with a boilerplate project. You can check out my extension to see how I do it.
An updated answer for 2022
Short answer: yes, you can require/import packages. Rather than going through the tedious work of setting up & configuring a bundler like Webpack on your own (especially if you have no experience with them), there are now build tools you can use to create the boilerplate "scaffolding" for a Chrome extension:
Extension CLI -- this one is well-documented and you can also reference the source code of some Chrome extensions that have used this tool (READ: learn how others have set up their code).
Chrome Extension CLI
Benefits of using them:
New projects are initiated with a default project file structure. Super helpful.
They support modern Javascript (ES6, ES2021), so modules work fine.
They already have bundlers integrated and pre-configured (Webpack in both above cases I think). You therefore don't need to install and configure any on your own.
You can use npm as normal to install any packages/dependencies you need.
Then of course, let the official documentation for Chrome Extensions guide you through the rest.
It's not possible to require node modules directly within a chrome extension. However, it is possible to bundle node applications and packages into the browser for use with your extensions. See here for more: Is it possible to develop Google Chrome extensions using node.js?
Yes, It is possible with esm npm packages.
require is commonjs module loader.
Browser doesn't support commonjs modules system
so that this error showed.
Method 1:
Run npm init -y and add "type" :"module" in your package.json.
create path.js file
add this line in path.js
const fullPath = await import.meta.resolve("npm-pkg-name");
const path = fullPath?.match(/(/node_modules.*)/)[0];
console.log(path);
add this line inside package.json
"path": "node --experimental-import-meta-resolve path.js",
Copy console output text. Replace package name with this copied path.
Method 2:
Install other npm package to find and replace
npm packages' virtual path to real path so that chrome browser will find it.
Install Path-fixxer
Add this line in path.js
import setAllPkgPath from "path-fixxer";
setAllPkgPath();
then run command : npm run path.
Now open browser to test it.
Everything seems to work fine, I just see those errors. Is this normal? How can i fix this.
My react application is written in Javascript, not in Typescript, but I do not think that this should matter, should it?
Are you using a package manager like npm/yarn/pnpm for installing react-router? Looking at that pathname it kinda looks like you're not and you should be.
If you're trying to import the index.tsx file directly in your JavaScript it won't work, you'll need the transpiled version which would be available automatically by installing it through a package manager (something like npm install react-router). The plain js files would then be available under node_modules/react-router in the root directory of your project.
To import it somewhere in a React project you could then use:
import { Route } from 'react-router'
(no need for the full path name including node_modules - more info on npm install here: https://docs.npmjs.com/cli/v6/commands/npm-install)
I've just restarted Visual Studio Code and the errors disappeared.
For context, I had Visual Studio running for some days now, so I can see how this could lead to some bugs.
I am creating Vue spa and integrating CKEditor here using this package I tried to do just like the tutorial by adding this to my app.js
import Vue from 'vue'
import ClassicEditor from '#ckeditor/ckeditor5-build-classic'
import documentEditor from '#ckeditor/ckeditor5-build-decoupled-document'
import VueCkeditor from 'vue-ckeditor5'
const options = {
editors: {
classic: ClassicEditor,
document: documentEditor
},
name: 'ckeditor'
}
Vue.use(VueCkeditor.plugin, options);
and to make it work I doing NPM install to those 2 editors (ClassicEditor and documentEditor)
npm install --save #ckeditor/ckeditor5-build-decoupled-document
and since I also need CKEditor but with much more simpler or to being said without image upload features then I for the ckeditor5 build classic and remove those plugin from there and then NPM build and then I am doing this on my Vue spa
npm install --save #ckeditor/ckeditor5-build-classic
after that, I open #ckeditor folder on node_modules and find the ckeditor5-build-classic folder and replace build folder with my custom version of CKEditor build classic
but then I get this error
ckeditor-version-collision: The global CKEDITOR_VERSION constant has already been set.
even though the editor still working, but I don't like the idea my console showing error
This problem is precisely described in docs, you can't run two editors from different builds on the same page (or mixing builds and source code).
tl;dr; The easiest way to enable running two different editors on the same site is to create a custom build that will export these two builds. This is described in the above docs.
The behavior has changed ~3 months ago and the error has been added to such situation to prevent bugs and big size of the bundle. Therefore the author of the https://github.com/igorxut/vue-ckeditor5 can just update the readme to follow the latest version's API.
I recommend to create "super build".
For example you can clone repository of classic build and change 3 files.
Check my gits.
I updated example1 for using this build.
I'm having terrible problems when trying to import an external JS project into my meteor folder. This is the project I'll like to use: http://www.outsharked.com/imagemapster/default.aspx?demos.html#beatles
As you can see, it is necessary to import two scripts. The first one is JQuery, and that was easily solved by adding it with meteor add jquery.
The problem came out when I tried to import the second script. I'm not sure how I can use it because, as far as I know, on meteor you cannot just import your script into the head section. For that reason, I've created a new template that is rendered and I put the code in there, but nothing happenend. Later on I've created an event that calls the JS when the image is clicked but without any success.
My question is, Which is the correct way to import a local JS code in meteor as in HTML is done with:
<script type="text/javascript" src="../dist/jquery.imagemapster.js"></script>
Since jquery-imagemapster is available as an npm package you can do:
$ npm install jquery-imagemapster
In your project directory and make it available to your project that way.
In early versions of Meteor packages were only available via atmosphere and $ meteor add. Later they added npm support and all npm packages became available.
Prefix npm installs with “meteor” -> “meteor npm install —save ‘js file’. Initializing will be the same as it would be in any other front end environment as will importing it. If you’re having trouble after that, check for it’s existance in your browser console and work from there using its built in properties and methods.
