Filing an Issue

Thanks for checking out N1! If you have a feature request, be sure to check out the open source roadmap. If someone has already requested the feature you have in mind, you can upvote the card on Trello—to keep things organized, we often close feature requests on GitHub after creating Trello cards.

If you've found a bug, try searching for similars issue before filing a new one. Please include the version of N1 you're using, the platform you're using (Mac / Windows / Linux), and the type of email account. (Gmail, Outlook 365, etc.)

Contributing to N1

The hosted sync engine allows us to control adoption of N1 and maintain a great experience for our users. However, the sync engine is open source and you can set it up yourself to begin using N1 immediately. Follow instructions on the sync engine repository.

Getting Started

First, clone and build N1 from source:

git clone https://github.com/nylas/N1.git
cd N1
script/bootstrap

Read the getting started guides.

See Windows instructions here

Linux users on Debian 8 and Ubuntu 15.04 onward must also install libgcrypt11, which Electron depends on.

Running N1

./N1.sh --dev

Once the app boots, you'll be prompted to enter your email credentials.

Testing N1

./N1.sh --test

This will run the full suite of automated unit tests. We use Jasmine 1.3.

It runs all tests inside of the /spec folder and all tests inside of /internal_packages/**/spec

Creating binaries

Once you've checked out N1 and run script/bootstrap, you can create a packaged version of the application by running script/build. Note that the builds available at https://nylas.com/N1 include licensed fonts, sounds, and other improvements. If you're just looking to run N1, you should download it there!

Pull requests

We require all authors sign our Contributor License Agreement before pull requests (even minor ones) can be accepted. (It's similar to other projects, like NodeJS Meteor, or React). I'm really sorry, but Legal made us do it.

Commit Format

We decided to not impose super strict commit guidelines on the community.

We're trusting you to be thoughtful, responsible, committers.

We do have a few heuristics:

  • Keep commits fairly isolated. Don't jam lots of different functionality in 1 squashed commit. git bisect and git cherry-pick should still be reasonable things to do.
  • Keep commits fairly significant. DO squash all those little file changes and "fixmes". Don't make it difficult to browse our history. Play the balance between this idea and the last point. If a commit doesn't deserve your time to write a long thoughtful message about, then squash it.
  • Be hyper-descriptive in your commit messages. I care less about what you did (I can read the code), I want to know WHY you did it. Put that in the commit body (not the subject). Itemize the major semantic changes that happened.
  • Read "How to Write a Git Commit Message" if you haven't already (but don't be too prescriptivist about it!)
