Electron Rebuild

This executable rebuilds native Node.js modules against the version of Node.js that your Electron project is using. This allows you to use native Node.js modules in Electron apps without your system version of Node.js matching exactly (which is often not the case, and sometimes not even possible).

How does it work?

Install the package with --save-dev:

npm install --save-dev electron-rebuild

Then, whenever you install a new npm package, rerun electron-rebuild:

$(npm bin)/electron-rebuild

Or if you're on Windows:


If you have a good node-gyp config but you see an error about a missing element on Windows like Could not load the Visual C++ component "VCBuild.exe", try to launch electron-rebuild in an npm script:

  "rebuild": "electron-rebuild -f -w yourmodule"

and then

npm run rebuild

How can I use this with Electron Forge?

This package is automatically used with Electron Forge when packaging an Electron app.

How can I integrate this into Electron Packager?

electron-rebuild provides a function compatible with the afterCopy hook for Electron Packager. For example:

import packager from 'electron-packager';
import rebuild from 'electron-rebuild';
  // … other options 
  afterCopy: [(buildPath, electronVersion, platform, arch, callback) => {
    rebuild({ buildPath, electronVersion, arch })
      .then(() => callback())
      .catch((error) => callback(error));
  // … other options 

How can I integrate this into Grunt / Gulp / Whatever?

electron-rebuild is also a library that you can just require into your app or build process. It has a very simple API:

import rebuild from 'electron-rebuild';
// Public: Rebuilds a node_modules directory with the given Electron version. 
// options: Object with the following properties 
//     appPath - An absolute path to your app's directory.  (The directory that contains your node_modules) 
//     electronVersion - The version of Electron to rebuild for 
//     arch (optional) - Default: process.arch - The arch to rebuild for 
//     extraModules (optional) - Default: [] - An array of modules to rebuild as well as the detected modules 
//     onlyModules (optional) - Default: null - An array of modules to rebuild, ONLY these module names will be rebuilt. 
//                                              The "types" property will be ignored if this option is set. 
//     force (optional) - Default: false - Force a rebuild of modules regardless of their current build state 
//     headerURL (optional) - Default: - The URL to download Electron header files from 
//     types (optional) - Default: ['prod', 'optional'] - The types of modules to rebuild 
//     mode (optional) - The rebuild mode, either 'sequential' or 'parallel' - Default varies per platform (probably shouldn't mess with this one) 
// Returns a Promise indicating whether the operation succeeded or not 

A full build process might look something like:

let childProcess = require('child_process');
let pathToElectron = require('electron-prebuilt');
    buildPath: __dirname,
    electronVersion: '1.4.12'
    .then(() =>'Rebuild Successful'))
    .catch((e) => {
      console.error("Building modules didn't work!");
