This page documents the Zulip directory structure, where to find things, and how to decide where to put a file.
You may also find the new application feature tutorial helpful for understanding the flow through these files.
Core Python files¶
Zulip uses the Django web framework, so a lot of these paths will be familiar to Django developers.
zproject/urls.pyMain Django routes file. Defines which URLs are handled by which view functions or templates.
zerver/models.pyMain Django models file. Defines Zulip's database tables.
zerver/lib/actions.pyMost code doing writes to user-facing database tables.
zerver/views/*.pyMost Django views.
zerver/webhooks/Webhook views and tests for Zulip webhook integrations.
zerver/lib/*.pyMost library code.
zerver/lib/bugdown/Backend Markdown processor.
See our translating docs for details on Zulip's templating systems.
static/styles/Zulip's own CSS.
static/assets/For assets not to be served to the web (e.g. the system to generate our favicons).
frontend_tests/node_tests/Node Frontend unit tests.
frontend_tests/casper_tests/Casper frontend tests.
tools/test-*Developer-facing test runner scripts.
These are distinguished from scripts, below, by needing to run a Django context (i.e. with database access).
zerver/management/commands/Management commands one might run at a production deployment site (e.g. scripts to change a value or deactivate a user properly).
scripts/Scripts that production deployments might run manually (e.g.,
scripts/lib/Scripts that are needed on production deployments but humans should never run directly.
scripts/setup/Scripts that production deployments will only run once, during installation.
tools/Scripts used only in a Zulip development environment. These are not included in production release tarballs for Zulip, so that we can include scripts here one wouldn't want someone to run in production accidentally (e.g. things that delete the Zulip database without prompting).
tools/for things only used during the development environment setup process.
tools/for things only used to setup and run our tests in Travis CI. Actual test suites should go in
API and Bots¶
api/Zulip's Python API bindings (released separately).
api/integrations/Integrations distributed as part of the Zulip API bundle.
api/bots/Bots distributed as part of the Zulip API bundle.
api/bots_api/Framework for running and testing bots in
Production puppet configuration¶
This is used to deploy essentially all configuration in production.
puppet/zulip/For configuration for production deployments.
puppet/zulip/manifests/voyager.ppMain manifest for Zulip standalone deployments.
Additional Django apps¶
confirmationEmail confirmation system.
analyticsAnalytics for the Zulip server administrator (needs work to be useful to normal Zulip sites).
corporateThe old Zulip.com website. Not included in production distribution.
zilencerPrimarily used to hold management commands that aren't used in production. Not included in production distribution.
Jinja2 Compatibility Files¶
