Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

  • Nothing (yet)!

4.0.0

Added

  • Client-side Python components can now be rendered via the new {% pyscript_component %} template tag
    • You must first call the {% pyscript_setup %} template tag to load PyScript dependencies
  • Client-side components can be embedded into existing server-side components via reactpy_django.components.pyscript_component.
  • Tired of writing JavaScript? You can now write PyScript code that runs directly within client browser via the reactpy_django.html.pyscript element.
    • This is a viable substitution for most JavaScript code.

Changed

  • New syntax for use_query and use_mutation hooks. Here's a quick comparison of the changes:

    query = use_query(QueryOptions(thread_sensitive=True), get_items, foo="bar") # Old
query = use_query(get_items, {"foo":"bar"}, thread_sensitive=True) # New

mutation = use_mutation(MutationOptions(thread_sensitive=True), remove_item) # Old
mutation = use_mutation(remove_item, thread_sensitive=True) # New

Removed

  • QueryOptions and MutationOptions have been removed. The value contained within these objects are now passed directly into the hook.

Fixed

  • Resolved a bug where Django-ReactPy would not properly detect settings.py:DEBUG.

3.8.1 - 2024-05-07

Added

  • Python 3.12 compatibility

3.8.0 - 2024-02-20

Added

  • Built-in cross-process communication mechanism via the reactpy_django.hooks.use_channel_layer hook.
  • Access to the root component's id via the reactpy_django.hooks.use_root_id hook.
  • More robust control over ReactPy clean up tasks!
    • settings.py:REACTPY_CLEAN_INTERVAL to control how often ReactPy automatically performs cleaning tasks.
    • settings.py:REACTPY_CLEAN_SESSIONS to control whether ReactPy should clean up expired sessions during automatic cleanups.
    • settings.py:REACTPY_CLEAN_USER_DATA to control whether ReactPy should clean up orphaned user data during automatic cleanups.
    • python manage.py clean_reactpy command to manually perform ReactPy clean up tasks.

Changed

  • Simplified code for cascading deletion of user data.

3.7.0 - 2024-01-30

Added

  • An "offline component" can now be displayed when the client disconnects from the server.
  • URL router now supports a * wildcard to create default routes.

3.6.0 - 2024-01-10

Added

  • Built-in Single Page Application (SPA) support!
    • reactpy_django.router.django_router can be used to render your Django application as a SPA.
  • SEO compatible rendering!
    • settings.py:REACTPY_PRERENDER can be set to True to make components pre-render by default.
    • Or, you can enable it on individual components via the template tag: {% component "..." prerender="True" %}.
  • New view_to_iframe feature!
    • reactpy_django.components.view_to_iframe uses an <iframe> to render a Django view.
    • reactpy_django.utils.register_iframe tells ReactPy which views view_to_iframe can use.
  • New Django User related features!
    • reactpy_django.hooks.use_user can be used to access the current user.
    • reactpy_django.hooks.use_user_data provides a simplified interface for storing user key-value data.
    • reactpy_django.decorators.user_passes_test is inspired by the equivalent Django decorator, but ours works with ReactPy components.
    • settings.py:REACTPY_AUTO_RELOGIN will cause component WebSocket connections to automatically re-login users that are already authenticated. This is useful to continuously update last_login timestamps and refresh the Django login session.

Changed

  • Renamed undocumented utility function ComponentPreloader to RootComponentFinder.
  • It is now recommended to call as_view() when using view_to_component or view_to_iframe with Class Based Views.
  • For thread safety, thread_sensitive=True has been enabled in all sync_to_async functions where ORM queries are possible.
  • reactpy_django.hooks.use_mutation now has a __call__ method. So rather than writing my_mutation.execute(...), you can now write my_mutation(...).

Deprecated

  • The compatibility argument on reactpy_django.components.view_to_component is deprecated.
    • Use view_to_iframe as a replacement.
  • reactpy_django.components.view_to_component usage as a decorator is deprecated.
    • Check the docs on how to use view_to_component as a function instead.
  • reactpy_django.decorators.auth_required is deprecated.
    • Use reactpy_django.decorators.user_passes_test instead.
    • An equivalent to auth_required's default is @user_passes_test(lambda user: user.is_active).

Fixed

  • Fixed a bug where exception stacks would not print on failed component renders.

3.5.1 - 2023-09-07

Added

  • Warning W018 (Suspicious position of 'reactpy_django' in INSTALLED_APPS) has been added.

???+ note "Django 4.2+ is required"

ReactPy-Django will continue bumping minimum Django requirements to versions that increase async support.

This "latest-only" trend will continue until Django has all async features that ReactPy benefits from. After this point, ReactPy-Django will begin supporting all maintained Django versions.

Removed

  • settings.py:REACTPY_RECONNECT_MAX is removed. See the docs for the new REACTPY_RECONNECT_* settings.

3.4.0 - 2023-08-18

Added

    • host argument has been added to the component template tag to force components to render on a specific host.
  • reactpy_django.utils.register_component function can manually register root components.
    • Useful if you have dedicated ReactPy rendering application(s) that do not use HTML templates.

Changed

  • ReactPy will now provide a warning if your HTTP URLs are not on the same prefix as your WebSockets.
  • Cleaner logging output for auto-detected ReactPy root components.

Added

  • ReactPy WebSocket will now decode messages via orjson resulting in an ~6% overall performance improvement.
  • Built-in asyncio event loops are now patched via nest_asyncio, resulting in an ~10% overall performance improvement. This has no performance impact if you are running your web server with uvloop.

Fixed

  • Fix bug where REACTPY_WEBSOCKET_URL always generates a warning if unset.
  • Fixed bug on Windows where assert f is self._write_fut would be raised by uvicorn when REACTPY_BACKHAUL_THREAD = True.
