Package your Meteor apps with Electron, and butter.


Easily package your Meteor apps with Electron, and butter.

Updated version notes:

This updated version of Electrify now defaults to Electron 1.4.0. When requiring Electrify, use require('electrify-updated-test') Also the developpement mode now uses 1.4.0 as well. Other than that there are a few tweaks here and there. Nothing major.

And if anyone is interested, I think ASAR support should be the next thing we should work on for this package. It would require some writing from the ground-up just so you know, given that this package relies on spawning mongo and node, and ASAR does not support that. If anyone's up to it, let me know.

This package belongs to its original author Anderson Arboleya. Check Meteor x Electron integration. The purpose of this fork is simply to keep it up to date and resolve some issues that keep cropping up as Electron and Meteor keep receiving new features.


Now, Electrify runs a self-contained MongoDB server. Running the app with electrify will run fine. However, once you package the app and run it, you might run into a MongoDB driver issue, something like

 The default storage engine 'wiredTiger' is not available with this build of mongod. Please specify a different storage engine explicitly, e.g. --storageEngine=mmapv1

causing the app not to start; That is because Electrify natively uses an older version of MongoDB than the one it bundles with your app (in fact, it copies the executables directly from your .meteor folder).

How to fix

Refer to this issue. Long story short, you must have an older version mongo.exe and mongod.exe (or executables, in the case of Linux) in your .electrify/bin folder before you package. You can find the link to those in the above link. Otherwise, if your app is already packaged, copy them to your/app/path/.../resources/app/bin. The first method just ensures that future packaging will not run into this issue each time.

Some more Tweaking

This case assumes you want to specify a distant MongoDB for your app (or change entirely to something like CouchDB). Now Electrify does not natively support that, and will ignore a MONGO_URL environnement variable if you pass one. Now to fix this, you need to modify this line: 'self.env.MONGO_URL = 'mongodb://localhost:'+ self.port +'/meteor'; to: self.env.MONGO_URL = process.env.MONGO_URL; in the lib/plugins/mongodb.js file

You can either modify this file in your global packages folder for this modification to be effective in all future projets. (see npm root -g), or inside your packaged app, my-electrified-app/resources/app/node_modules/electrify-updated-test/lib/plugins/mongodb.js

TL;DR (Old docs, still useful)

npm install -g electrify

For invoking Electron methods from Meteor, you'll also need to install the arboleya:electrify meteor package. For more info check Meteor x Electron integration.

Running app

cd /your/meteor/app


cd /your/meteor/app
electrify package

The packaging process is done under the hood using electron-packager npm package. The following variables are automatically set:

  • --out -- comes from cli option [-o, --out]
  • --arch -- comes from system [current arch]
  • --platform -- comes from system [current platform]
  • --version -- comes from .electrify/package.json [current app version]

You can overwrite these default values and also set others by passing custom arguments directly to electron-packager after --, i.e:

cd /your/meteor/app
electrify package -- --icon=/folder/x/img/icon.png --version=x.y.z

All the available options for electron-packager can be found here:


The output app will match your current operational system and arch type.

  • To get an OSX app, run it from a Osx machine.
  • To get an Linux 32bit app, run it from a 32bit Linux machine.
  • To get an Linux 64bit app, run it from a 64bit Linux machine.
  • To get an Windows 32bit app, run it from a 32bit Windows machine.
  • To get an Windows 64bit app, run it from a 64bit Windows machine.

Due to NodeJS native bindings of such libraries such as Fibers -- which are mandatory for Meteor, you'll need to have your Meteor app fully working on the desired platform before installing this plugin and packaging your app.

So, at this time, you cannot package your app in a cross-platform fashion from one single OS.

Perhaps you can live with it? :)

DO NOT use options to output for multiple arch/platforms at once, such as --arch=all. It won't work, Electrify can bundle Meteor apps only for the platform you're running on.


  1. -i, --input - Meteor app folder, default is current directory (process.cwd()).
  2. -o, --output - Sets output folder for your packaged app, default is /your/meteor/app/.dist
  3. -s, --settings Sets path for Meteor settings file, this will be available inside your Meteor code both in development and after being packaged.


You'll notice a new folder called .electrify in your meteor app dir, its structure will be like this:

├── .electrify
│   ├── .gitignore
│   ├── electrify.json
│   ├── index.js
│   └── package.json
├── .meteor
└── ...

This is a pure Electron project, so you can use the whole Electron API from JS files in this folder. Also, you can install electron dependencies and store them in the package.json file. Note that the electrify package is itself a dependency.

See this folder as the desktop layer for your Meteor app. Remember to check out the index.js file, it constains the electrify start/stop usage.

The electrify.json file will hold specific preferences for Electrify, such as plugins and so on. It's still a WIP, but you can get around it.

Config (electrify.json)

For now there's only one option here: preserve_db.

Set it to true to preserve database between installs. It works by saving the mongo data dir inside user's data folder, instead of being self contained within the app folder (which gets deleted when new version is installed).


Let's see how one would be able to do a simple SplashScreen:

var app       = require('app');
var browser   = require('browser-window');
var electrify = require('electrify')(__dirname);
var window = null;
var splash = null; // splash variable 
app.on('ready', function() {
  splash = new browser({ // starts splash window 
    // >>> your configs here 
  splash.loadUrl('./splash.html'); // create the ".electrify/splash.html" file 
  // then move along and start electrify 
  electrify.start(function(meteor_root_url) {
    // before opening a new window with your app, destroy the splash window 
    splash.close(); // >>> or .destroy(), check what works for you 
    // from here on, well, nothing changes.. 
    window = new browser({
      width: 1200, height: 900,
      'node-integration': false // node integration must to be off 
// .... 

Meteor x Electron integration

You can seamlessly call Electron methods from your Meteor's client/server code.

Define your Electron methods inside the .electrify folder:

// `.electrify/index.js` file 
  '': function(firstname, lastname, done) {
    // do things with electron api, and then call the `done` callback 
    // as ~> done(err, res); 
    done(null, 'Hello '+ firstname +' '+ lastname +'!');

Then, in your Meteor code (client and server), you can call this method like:

//, args, done_callback);'', ['anderson', 'arboleya'], function(err, msg) {
  console.log(msg); // Hello anderson arboleya! 


You can only call methods after the connection is made between Meteor and Electron, to make sure it's ready you can wrap your code in a startup block:



When upgrading to newer versions, it's important to know that:

~> templates

Once these files exists on disk, they will not be overwritten.

  • .electrify/index.js
  • .electrify/package.json
  • .electrify/electrify.json
  • .electrify/.gitignore.json

~> api

As these files above is never overwritten, in case of any API change that needs adjustments, these will have to be made manually.

~> version matching

Always keep the same electrify version in your Meteor, and inside the .electrify folder, as per specified in .electrify/package.json file.

This is very young and active software, so make sure your are always up to date before opening an issue. Follow the released fixes through the file.

If you find any problem, please open a meaningful issue describing in detail how to reproduce the problem, which platform/os/arch type you're using, as well as the version of Meteor and Electrify, and any other info you may find usefull.
