Adding your app

If you have an Electron application you'd like to see added, please open a pull request! All that's required is a basic YML file and a PNG icon.

Using the wizard 🔮

This repository has a CLI wizard much like npm init that you can use to generate a YML datafile for your app. To use the wizard, fork and clone this repository, then run:

git clone https://github.com/electron/electron-apps
cd electron-apps
npm install && npm run wizard

Adding your app by hand 💪

Another easy way to add a new app is to copy an existing app and edit its metadata.

To do so, create a new directory in the apps directory and include a .yml file and .png icon file. The directory can only contain numbers, lowercase letters, and dashes, and the yml and icon files should be named like so:

apps
└── my-cool-app
    ├── my-cool-app-icon.png
    └── my-cool-app.yml

  • Must be at least 256px by 256px
  • Must not be a copy of another company's or application's icon (see submission guidelines below)

Locales

By default, your app is assumed to be designed for English speakers. If your app supports a different language (or multiple languages), please add a locales property that lists all locales supported.

Example:

name: fangyuanjian
description: 'collaboration and messaging for small-to-medium sized businesses.'
website: 'http://bzsns.cn/'
keywords:
    - messaging
    - collaboration
locales:
  - zh-CN

Company Logos and Names

Our legal team has advised us to disallow apps that are using the names of other companies or icons that we find too similar to the logos of other companies without verifying their permission to do so.

App names should not start with the word "GitHub". In general, you may refer to GitHub in a relational phrase to say that the project is "compatible with", "on", or "for" GitHub, or something along those lines.

For more details, see the GitHub logo guidelines.

Submission Guidelines

Some things to keep in mind when preparing your app for submission. Heavily inspired by the awesome-electron submission guidelines.

  • The pull request should have a useful title and include a link to the thing you're submitting and why it should be included.
  • Don't use another company's trademarks (icon, logo or name) without supplying evidence of prior permission
  • If you just created something, wait at least 20 days before submitting.
  • If you're submitting a closed source app, include evidence of it being built with Electron.
  • Submitted open source apps should have a readme, screenshot of the app in the readme, and a binary for at least one OS, preferably macOS, Linux and Windows.
  • Keep descriptions short and simple, but descriptive.
  • Start the description with a capital and end with a full stop/period.
  • Don't mention Electron in the description as it's implied.
  • Don't start the description with A or An.
  • Check your spelling and grammar.

Releases

Once your pull request has been merged, your changes will automatically be published in a new release of the electron-apps npm module, and will be displayed on the electronjs.org website shortly thereafter. This process involves a number of scheduled process, and typically takes 20-30 minutes.

Removing or Disabling Apps

Sometimes it's necessary to remove an app for this registry. To do so, add a disabled property to the app's YML file, followed a comment explaining the reason for removing it.

disabled: true # Nylas was sunset and replaced by Mailspring

This approach keeps the app data on hand, giving the app developer an option to resurrect the app at a later date by simply removing the flag.

How it Works

This package is a joint effort between humans and robots.

First, a human adds an app:

apps
└── hyper
    ├── hyper-icon.png
    └── hyper.yml

The yml file requires just a few fields:

name: Hyper
description: 'HTML/JS/CSS Terminal'
website: 'https://hyper.is'
repository: 'https://github.com/zeit/hyper'
category: 'Developer Tools'

Humans can include other data like keywords and license, but they're not required to do so.

The human then opens a PR. Tests pass, the PR gets merged. Yay!

Later, a bot comes along and adds more data about the app.

First, the date the app was submitted is inferred from the git history. Humans could provide this metadata, but they shouldn't have to. Let the machines do the work.

date: 2017-02-15

Then, the bot creates resized versions of the app icon:

hyper
├── hyper-icon-128.png
├── hyper-icon-32.png
├── hyper-icon-64.png
├── hyper-icon.png
└── hyper.yml

Then the bot extracts a color palette from the app icon:

iconColors: ['#FF0000', '#C54F23', '#DD8833']

And it also picks some colors that are "on brand" for use on black or white backgrounds:

goodColorOnWhite: '#916E02'
goodColorOnBlack: '#FCCC36'
faintColorOnWhite: 'rgba(80, 0, 0, 0.1)

Lastly, the bot commits changes to git, pushes to GitHub, and publishes a new release to npm.

Development

To develop this thing locally, there are a few things you should know:

You'll need a GitHub token to run the build task. Put it in a file named .env. It will be ignored by git.

cp .env.example .env

Testing

On Travis CI, the npm test command is run, which only tests human-submitted data.

When cutting a new release (which is normally done automatically by a Heroku scheduler process), the npm run test-all command is run, which tests not only the human-submitted data, but also the artifacts generated by the build process, like resized icons, icon color palettes, releases data, etc.
