Beta 0.5.1

Dev and contributing

Built with Electron. The main skeleton of the app is based on szwacz/electron-boilerplate. I strongly recommend reading the readme in his repo. Basically, the ES6 javascript files and less stylesheets can be found at ./src/ while the static files and those that do not need processing are in ./app/.

Any contribution or suggestion is accepted. Feel free to create any report for issues or app crashes. You can also use the report link provided in the application menu to create a crash report. Pull requests are accepted.

Known bugs
  • View headers inside an email does not work


e2e testing runs with Spectron inside a Docker container.

  • $ docker build -t protonmail-desktop-e2e --rm .
  • $ docker run protonmail-desktop-e2e

All features should be covered within the tests.

Running the App


You can build your own executables from the latest source by running one of the commands below. More stable, older executables can be found here.

Compiling from source

The installer is provided by electon-builder and processed through gulp thanks to electron-boilerplate.

This will work on OS X, Linux, and Windows. You will need Yarn to run this app.

  • Install required packages: $ yarn install
  • Run: $ yarn start
  • Build: $ yarn build
  • Package in a distributable format: $ yarn run dist
  • Generate package directory without distributable: $ yarn run pack

The building settings is in ./package.json and additional configuration instructions can be found here. The building process will only create version for the current OS. For creating MacOS, Windows and Linux distributable you need to run the command from each OS.
