Nylas Mail - the open-source, extensible mail client

Nylas Mail was an open-source mail client built on the modern web with Electron, React, and Flux. It was designed to be easy to extend, and many third-party plugins are available that add functionality to the client.

⚠️ Nylas Mail was initially released and open-sourced in early 2015 and was maintained by Nylas until Spring 2017. While Nylas no longer supports Nylas Mail, you can download the latest release or build it from source. There are also several forks that are being actively developed and maintained.

Getting Started

Setup your Environment (Mac):

Install Homebrew
Install NVM & Redis brew install nvm redis
Install Node 6 via NVM: nvm install 6
npm install

Setup your Environment (Linux - Debian/Ubuntu):

Install Node 6+ via NodeSource (trusted):
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs
Install Redis locally sudo apt-get install -y redis-server redis-tools benefit of letting us use subdomains.
npm install

Running Nylas Mail

npm run client: Starts the app
npm run test-client: Run the tests
npm run lint-client: Lint the source (ESLint + Coffeelint + LESSLint)

Exploring the Source

This repository contains the full source code to the Nylas Mail client and it's backend services. It is divided into the following packages:

Isomorphic Core: Shared code across local client and cloud servers
Client App: The main Electron app for Nylas Mail mirrored to open source repo.
Client Sync: The local mailsync engine integreated in Nylas Mail
Client Private Plugins: Private Nylas Mail plugins (like SFDC)
Cloud API: The cloud-based auth and metadata APIs for N1
Cloud Core: Shared code used in all remote cloud services
Cloud Workers: Cloud workers for services like send later

See /packages for the separate pieces. Each folder in /packages is designed to be its own stand-alone repository. They are all bundled here for the ease of source control management.

Digging Deeper

In early 2016, the Nylas Mail team wrote extensive documentation for the app that was intended for plugin developers. This documentation lives on GitHub Pages and offers a great overview of the app's architecture and important classes. Here are some good places to get started:

The team has also given conference talks and published blog posts about the client:

Running the Cloud

When you download and build Nylas Mail from source it runs without its cloud components. The concept of a "Nylas ID" / subscription has been removed, and plugins that require server-side processing are disabled by default. (Plugins like Snooze, Send Later, etc.)

In order to use these plugins and get the full Nylas Mail experience, you need to deploy the backend infrastructure located in the cloud-* packages. Deploying these services is challenging because they are implemented as microservices and designed to be run at enterprise scale with Redis, Postgres, etc. Because these backend services must access your email account, it is also important to use security best-practices (at the very least, SSL, encryption at rest, and a partitioned VPC). For more information about building and deploying this part of the stack, check out the cloud-core README.

Themes

The Nylas Mail user interface is styled using CSS, which means it's easy to modify and extend. Nylas Mail comes stock with a few beautiful themes, and there are many more which have been built by community developers

When you install packages, they're moved to ~/.nylas-mail/packages, and Nylas Mail runs apm install on the command line to fetch dependencies listed in the package's package.json

Forks

There are several forks of Nylas Mail that you should check out. If you're just learning about Nylas Mail, it is highly recommended you use one of these instead.

Mailspring - Significant rewrite by one of the original authors focused on performance and cloud plugins
