Zulip 2016 Roadmap
==================
## Introduction
Zulip has received a great deal of interest and attention since it was
released as free and open source software by Dropbox. That attention
has come with a lot of active development work from members of the
Zulip community. From when Zulip was released as open source in late
2016-11-02 18:32:14 +01:00
September 2015 through today (early November, 2016), over 1000 pull
requests have been submitted to the various Zulip repositories (and
nearly 1000 have been merged!), the vast majority of which are
submitted by Zulip's users around the world (as opposed to the small
core team that reviews and merges the pull requests).
2016-04-09 23:16:39 +02:00
In any project, there can be a lot of value in periodically putting
together a roadmap detailing the major areas where the project is
hoping to improve. This can be especially important in an open source
project like Zulip where development is distributed across many people
around the world. This roadmap is intended to organize a list of the
2016-06-02 19:16:56 +02:00
most important improvements that should be made to Zulip in the
2016-04-09 23:16:39 +02:00
relatively near future. Our aim is to complete most of these
improvements in 2016.
This document is not meant to constrain in any way what contributions
to Zulip will be accepted; instead, it will be used by the Zulip core
team to prioritize our efforts, measure progress on improving the
Zulip product, hold ourselves accountable for making Zulip improve
rapidly, and celebrate members of the community who contribute to
projects on the roadmap.
If you're someone interested in making a larger contribution to Zulip
and looking for somewhere to start, this roadmap is the best place to
look for substantial projects that will definitely be of value to the
community (if you're looking for a starter project, see the [guide to
getting involved with
Zulip](https://github.com/zulip/zulip#how-to-get-involved-with-contributing-to-zulip)).
2016-06-22 02:30:33 +02:00
We occasionally update this roadmap by adding strikethrough for issues
that have been resolved.
2016-04-09 23:16:39 +02:00
Without further ado, below is the Zulip 2016 roadmap.
## Burning problems
The top problem for the Zulip project is the state of the mobile apps.
The Android app has started seeing rapid progress thanks to a series
2016-07-27 04:00:29 +02:00
of contributions by Lisa Neigut of Recurse Center, and we believe it
is on a good path. The iOS app has fewer features than Android and
2016-04-09 23:16:39 +02:00
has more bugs, but more importantly is in need of an experienced iOS
developer who has time to drive the project.
2016-07-20 19:28:35 +02:00
Update: Neeraj Wahi is leading an effort on to write a [new React
Native iOS app for Zulip](https://github.com/zulip/zulip-mobile) to
replace the old iOS app.
2016-04-09 23:16:39 +02:00
## Core User Experience
This category includes important improvements to the core user
experience that will benefit all users.
2016-07-20 19:28:35 +02:00
* < strike > [Improve missed message notifications to make "reply" work nicely](https://github.com/zulip/zulip/issues/612)</ strike >
2016-04-09 23:16:39 +02:00
* [Add support for showing "user is typing" notifications ](https://github.com/zulip/zulip/issues/150 )
* [Add pretty bubbles for recipients in the compose box ](https://github.com/zulip/zulip/issues/595 )
2016-07-20 19:28:35 +02:00
* < strike > [Finish and merge support for pinning a few important streams](https://github.com/zulip/zulip/issues/285)</ strike >
2016-04-09 23:16:39 +02:00
* [Display stream descriptions more prominently ](https://github.com/zulip/zulip/issues/164 )
* [Integration inline URL previews ](https://github.com/zulip/zulip/issues/406 )
* [Add support for managing uploaded files ](https://github.com/zulip/zulip/issues/454 )
* [Make Zulip onboarding experience smoother for teams not used to topics ](https://github.com/zulip/zulip/issues/647 ). That specific proposal might not be right but the issue is worth investing time in.
## Ease of setup and onboarding issues
This category focuses on issues users experience when installing a new
Zulip server or setting up a new Zulip realm.
* [Document or better script solution to rabbitmq startup issues ](https://github.com/zulip/zulip/issues/465 )
2016-11-02 18:41:40 +01:00
## Production installation issues
2016-04-09 23:16:39 +02:00
* [Add a mechanism for deleting early test messages ](https://github.com/zulip/zulip/issues/135 )
* [Merge a supported way to use Zulip in Docker in production
implementation](https://github.com/zulip/zulip/pull/450).
## User Experience at scale
There are a few parts of the Zulip UI which could benefit from
overhauls designed around making the user experience nice for large
teams.
* [Make the buddy list work better for large teams ](https://github.com/zulip/zulip/issues/236 )
* [Improve @-mentioning syntax based on stronger unique identifiers ](https://github.com/zulip/zulip/issues/374 )
2016-11-12 01:24:20 +01:00
* < strike > [Show subscriber counts on streams](https://github.com/zulip/zulip/pull/525)</ strike >
2016-10-16 22:09:28 +02:00
* < strike > [Make the streams page easier to navigate with 100s of streams](https://github.com/zulip/zulip/issues/563)</ strike >
2016-07-20 19:28:35 +02:00
* < strike > [Add support for filtering long lists of streams](https://github.com/zulip/zulip/issues/565)</ strike >
2016-04-09 23:16:39 +02:00
## Administration and management
Currently, Zulip has a number of administration features that can be
controlled only via the command line.
2016-06-22 02:30:33 +02:00
* < strike > [Make default streams web-configurable](https://github.com/zulip/zulip/issues/665)</ strike >
* < strike > [Make realm emoji web-configurable](https://github.com/zulip/zulip/pull/543)</ strike >
2016-04-09 23:16:39 +02:00
* [Make realm filters web-configurable ](https://github.com/zulip/zulip/pull/544 )
* [Make realm aliases web-configurable ](https://github.com/zulip/zulip/pull/651 )
* [Enhance the LDAP integration and make it web-configurable ](https://github.com/zulip/zulip/issues/715 )
* [Add a SAML integration for Zulip ](https://github.com/zulip/zulip/issues/716 )
* [Improve administrative controls for managing streams ](https://github.com/zulip/zulip/issues/425 )
## Scalability
Zulip should support 10000 users in a realm and also support smaller
realms in more resource-constrained environments (probably a good
initial goal is working well with only 2GB of RAM).
* [Make the Zulip Tornado service support horizontal scaling ](https://github.com/zulip/zulip/issues/445 )
* [Make presence system scale well to 10000 users in a realm. ](https://github.com/zulip/zulip/issues/728 )
* [Support running queue workers multithreaded in production to
decrease minimum memory footprint](https://github.com/zulip/zulip/issues/34)
## Performance
Performance is essential for a communication tool. While some things
2016-07-27 04:00:29 +02:00
are already quite good (e.g. narrowing and message sending is speedy),
2016-04-09 23:16:39 +02:00
this is an area where one can always improve. There are a few known
performance opportunities:
2016-06-22 02:30:33 +02:00
* < strike > [Migrate to faster jinja2 templating engine](https://github.com/zulip/zulip/issues/620)</ strike >
2016-07-20 19:28:35 +02:00
* < strike > [Don't load zxcvbn when it isn't needed](https://github.com/zulip/zulip/issues/263)</ strike >
2016-04-09 23:16:39 +02:00
* [Optimize the frontend performance of loading the Zulip webapp using profiling ](https://github.com/zulip/zulip/issues/714 )
## Technology improvements
Zulip should be making use of the best Python/Django tools available.
* [Add support for Zulip running on Python 3 ](https://github.com/zulip/zulip/issues/256 )
* [Add support for changing users' email addresses ](https://github.com/zulip/zulip/issues/734 )
* [Automatic thumbnailing of uploaded images ](https://github.com/zulip/zulip/issues/432 )
* [Upgrade Zulip to use Django 1.10 once it is released. The patches
needed to run Zulip were merged into mainline Django in Django 1.10,
so this will mean we don't need to use a fork of Django anymore.](https://github.com/zulip/zulip/issues/3)
## Technical Debt
While the Zulip server has a great codebase compared to most projects
of its size, it takes work to keep it that way.
* [Migrate most web routes to REST API ](https://github.com/zulip/zulip/issues/611 )
2016-11-12 01:24:20 +01:00
* < strike > [Finish purging global variables from the Zulip JavaScript](https://github.com/zulip/zulip/issues/610)</ strike >
2016-10-16 22:09:28 +02:00
* < strike > [Finish deprecating and remove the pre-REST Zulip /send_message API](https://github.com/zulip/zulip/issues/730)</ strike >
2016-04-09 23:16:39 +02:00
* [Split Tornado subsystem into a separate Django app ](https://github.com/zulip/zulip/issues/729 )
2016-10-16 22:09:28 +02:00
* < strike > [Clean up clutter in the root of the zulip.git repository](https://github.com/zulip/zulip/issues/707)</ strike >
2016-04-09 23:16:39 +02:00
* [Refactor zulip.css to be broken into components ](https://github.com/zulip/zulip/issues/731 )

2016-07-13 04:22:21 +02:00
* [Use a JavaScript bundler like webpack ](https://github.com/zulip/zulip/issues/695 )
2016-04-09 23:16:39 +02:00
## Documentation
* [Significantly expand documentation of the Zulip API and integrating
with Zulip.](https://github.com/zulip/zulip/issues/672)
* [Expand library of documentation on Zulip's feature set. Currently
most documentation is for either developers or system administrators.](https://github.com/zulip/zulip/issues/675)
2016-11-12 01:24:20 +01:00
* < strike > [Expand developer documentation with more tutorials explaining how to do

* [Update all screenshots to show the current Zulip UI ](https://github.com/zulip/zulip/issues/599 )
## Integrations
Integrations are essential to Zulip. While we currently have a
reasonably good framework for writing new webhook integrations for
getting notifications into Zulip, it'd be great to streamline that
process and make bots that receive messages just as easy to build.
* [Add an outgoing webhook integration system ](https://github.com/zulip/zulip/issues/735 )
* [Make setting up a new integration a smooth flow ](https://github.com/zulip/zulip/issues/692 )

2016-04-09 23:16:39 +02:00
## Android app
The Zulip Android app is ahead of the iOS app in terms of feature set,
2016-07-27 04:00:29 +02:00
but there is still a lot of work to do. Most of the things listed below
will eventually apply to the iOS app as well.
2016-04-09 23:16:39 +02:00
2016-07-20 19:28:35 +02:00

2016-04-09 23:16:39 +02:00
## iOS app
Most of the projects listed under Android apply here as well, but it's
worth highlighting some areas where iOS is substantially behind
Android. The top priority here is recruiting a lead developer for the
iOS app. Once we have that resolved, we'll expand our ambitions for
the app with more specific improvements.

2016-04-09 23:16:39 +02:00
## Desktop apps
2016-07-28 04:43:53 +02:00
The top goal for the desktop apps is to rebuild it in a modern
toolchain so that it's easy for a wide range of developers to
contribute to the apps. The new [cross-platform
app](https://github.com/zulip/zulip-electron) is implemented in
[Electron ](http://electron.atom.io/ ), a framework (maintained by
GitHub) that uses Chromium and Node.js, so Zulip developers only need
to write HTML, CSS, and JavaScript. The new Zulip app is in alpha as of
early August 2016.
2016-04-09 23:16:39 +02:00
* Migrate platform from QT/webkit to Electron
* Desktop app doesn't recover well from entering the wrong Zulip server
2016-07-28 04:43:53 +02:00
* [Support having multiple Zulip realms open simultaneously ](https://github.com/zulip/zulip-electron/issues/1 )
2016-04-09 23:16:39 +02:00
* Build an efficient process for testing and releasing new versions of
the desktop apps
## Community
These don't get GitHub issues since they're not technical projects,
but they are important goals for the project.
