What is the process of exporting a module assigned to a variable in JavaScript?

My approach to making the require visible in <app></app> is as follows:

index.html:

<script>
  var electron = require('electron')
</script>
<app></app>
<script src="bundle.js"></script>

App.vue:

const ipc = electron.ipcRenderer
console.log(ipc)

However, I encountered ESLint errors for using an un-used and un-defined variable. To address this, I opted for the following solution:

requires.js:

var electron = require('electron')

exports.electron = electron

index.html:

  <script src="requires.js"></script>
</head>

<body>
  <app></app>
  <script src="bundle.js"></script>

This new implementation led to the error:

requires.js:3 Uncaught ReferenceError: exports is not defined
.

What is the correct method to export and import the electron require?

Note: directly requiring electron in App.vue does not work. The proper location to require electron is within index.html

Answer №1

To create a global variable for electron, you can set

window.electron = require('electron')
in your index.html file. However, relying on globals is considered bad practice. It's better to simply use require in your code instead.

If you are facing issues with the require function not working as expected, it may be due to bundling processes like webpack. In such cases, try renaming Electron's require to distinguish between bundling-time and runtime resolutions. You can achieve this by using window.electronRequire = require in your index.html script tag and then calling electronRequire('electron') in your code.

Consider whether bundling all files into one is necessary for your Electron project. Since Electron supports full Node integration, you can utilize regular Node modules without the need for HTTP requests. Therefore, there may not be much benefit in consolidating everything into a single bundled file.
