v0.7.2

What's Changed

Deprecated instantiating components through Component.init

You should have probably been doing .create.

• deprecate Component init by @adhami3310 in #4904

Overwrite rx.serializer

You can overwrite a serializer in reflex through @rx.serializer (previously we were erroring here), for example:

@serializer(to=str, overwrite=True) # overwrite flag here suppresses warning about overriding a builtin serializer as an intentional decision
def serialize_uuid(uuid: UUID) -> str:
    return "UUID" + str(uuid)

• serialize uuid and allow overwriting serializers by @adhami3310 in #4888

Use .f with Vars

You can now use the .f in f-strings with state Vars, for example:

class State(rx.State):
  value_of_pi: float = 3.14159265359

rx.text(f"{State.value_of_pi:.2f}")

Note that we now error when you provide a formatter that we don't support. PRs are welcome in extending the functionality beyond :.Xf.

• add support for .f format by @adhami3310 in #4855

• update all radix deps by @adhami3310 in #4886
• opt for powershell as opposed to wmic by @adhami3310 in #4862

• [ENG-4776] Write stateful pages marker earlier when should_compile is False by @masenf in #4868
• reduce badge perf impact on pages by @Lendemor in #4872

Full Changelog: v0.7.1...release/reflex-0.7.2

v0.7.1

Breaking Changes

• rx.var decorated functions cannot take arguments (it didn't work before, but now it raises exception)

New Features

rx.auto_scroll

A new container that automatically scrolls to the bottom when new content is added.

• Add auto scroll by @adhami3310 in #4790

New Var Operations for StringVar: .title(), .capitalize()

• add capitalize and title var operations by @adhami3310 in #4840

Improvements

Compile with Main Thread by Default

The new default is to compile pages on the main thread, not using an executor. For most normal-sized apps, this is faster because it avoids spinning up threads and associated overhead.

• give option to only use main thread by @adhami3310 in #4809

Component Props

Components as props was previously working, however in some situations, the necessary hooks/imports/custom_code associated with the component would not propagate up to the parent component and be lost. This change correctly propagates data from the component as prop for correct code generation.

• components deserve to be first class props by @adhami3310 in #4827

Performance

• import var perf improvements by @adhami3310 in #4813
• only write if file changed by @adhami3310 in #4822

• @slackroo made their first contribution in #4831

Full Changelog: v0.7.0...v0.7.1

v0.7.0

Breaking Changes

Python 3.9 support is no longer supported.

Computed Vars are now cache=True by default

Explicitly set cache=False on Computed Vars that should be updated after every
event, which was the previous default behavior.

The dependency tracking analysis for Computed Vars has been improved to support
async Computed Vars, so there is a possibility for unanticipated behavior change
around tracking dependencies. Please report any bugs encountered in this area.

• computed var default to cache=True by @Lendemor in #4194

Previously "CallableVar" shims need to be explicitly called

• rx.upload_file -> rx.upload_file()
• rx.selected_files -> rx.selected_files()
• rx.clear_selected_files -> rx.clear_selected_files()
• rx.set_color_mode -> rx.set_color_mode()

Deprecation Removals

Usage of these features prior to 0.7.0 printed a deprecation warning, now they will result in an error.

• rx.chakra is removed, use import reflex_chakra as rc instead.

• rx.background is removed, use rx.event(background=True) instead.

• rx.Component._create_event_chain is removed, use rx.EventChain.create instead.

• external prop for rx.redirect is removed.

• Unannotated event handler arguments will now raise MissingAnnotationError.

• Many internal exceptions were renamed to add a trailing Error suffix if that was missing.

• rx._x.asset is removed, use rx.asset instead.

• Passing a str argument to rx.utils.console.set_log_level will now raise TypeError.

• Removals from rx.utils.exec:

  • is_frontend_only -> rx.config.environment.REFLEX_FRONTEND_ONLY.get()
  • is_backend_only -> rx.config.environment.REFLEX_BACKEND_ONLY.get()
  • should_skip_compile -> rx.config.environment.REFLEX_SKIP_COMPILE.get()

• rx.utils.format.format_event_chain is removed, use str(rx.Var.create(chain)) instead.

• _var_is_local and _var_is_string removed from rx.Var.create.

• Computed Vars without a return type annotation will raise UntypedComputedVarError.

• removing deprecated features for 0.7.0 and removing py3.9 support by @Lendemor in #4586

rx.App fields for internal use now have a _ prefix

• rename private fields with leading underscore in App by @Lendemor in #4642

New Features

reflex rename

A new command to rename an app.

• [ENG-1796]reflex rename- B by @ElijahAhianyo in #4668

rx.var now supports async functions

An rx.var computed var can now wrap an async function, which can access
arbitrary state via get_state and var values via get_var_value.

Dependency tracking across states is supported, but there may be edge cases in
the new implementation that prevent depedencies from being automatically
identified. You can pass explicit dependencies to the deps argument, and can
add dependencies at runtime via cls.computed_vars[var_name].add_dependency.
For best results, pass a globally imported state class to get_state and assign
the return value to a local variable in the function.

• [ENG-4326] Async ComputedVar by @masenf in #4711

"Built with Reflex" badge

To raise awareness of Reflex, a sticky "Built with Reflex" badge is added to the
lower right corner of each page.

For subscribers of Reflex Cloud, this badge can be disabled by setting
show_built_with_reflex=False in rxconfig.py or SHOW_BUILT_WITH_REFLEX=0 in
the environment.

For more information see: https://reflex.dev/docs/hosting/reflex-branding/

• Add a sticky Built with Reflex badge by @Lendemor in #4584
• Sticky tweaks: only show in prod mode by @masenf in #4789

Improvements

Support For Dynamic Icon name

Previously the recommendation was to use rx.match to map icons, because the
icon name itself could not be a Var.

With rx.dynamic_icon, the name can now be a Var, but performance may be
affected by dynamic loading.

• allow dynamic icons name by @Lendemor in #4636

Support for Specifying Custom App Module

A new config knob is added to rxconfig.py, to load the app from a module other than the default.

config = rx.Config(
    app_name="my_app",
    app_module_import="some_package.my_actual_app_module",
)

The app module should be importable by name with the current PYTHONPATH / sys.path, and contain an app attribute.

• [ENG-4134]Allow specifying custom app module in rxconfig by @ElijahAhianyo in #4556

v0.6.8

New Features

New API: rx.EventChain.create

This new interface makes it easier to transform EventType (EventHandler, EventSpec, and lambda - as accepted by component event triggers) into EventChain to be rendered in hook calls or rx.call_script / rx.call_function invocations.

• Move _create_event_chain to EventChain.create by @masenf in #4557

New API: BaseState.get_var_value

Similar to get_state, this API provides access to a Var defined in another state. If the value is mutable, changing it will be reflected in the other state. This API is intended for use with ComponentState implementations that want to "borrow" data from another state.

Show Example Code

from typing import ClassVar

import reflex as rx


class MyState(rx.State):
    data: list[dict] = []


class Appender(rx.ComponentState):
    _data: ClassVar[rx.Var]

    async def add_value(self, form_data: dict):
        (await self.get_var_value(self._data)).append(form_data)

    @classmethod
    def get_component(cls, data: rx.Var[list[dict]]) -> rx.Component:
        cls._data = data
        return rx.card(
            rx.form(
                rx.vstack(
                    rx.input(placeholder="Name", name="name", autofocus=True),
                    rx.input(placeholder="Email", name="email"),
                    rx.button("Submit", type="submit"),
                ),
                reset_on_submit=True,
                on_submit=cls.add_value,
            ),
        )


appender = Appender.create


def index() -> rx.Component:
    return rx.vstack(
        rx.foreach(
            MyState.data,
            lambda d: rx.text(d.to_string()),
        ),
        appender(data=MyState.data),
    )


app = rx.App()
app.add_page(index)

• BaseState.get_var_value helper to get a value from a Var by @masenf in #4553

Improvements

Add .endswith() var operation for strings

• Add endswith method to String class by @5quinque in #4577

Simpler API for rx._x.client_state

• external prop of rx.redirect is renamed to is_external for consistency.
  • Unify is_external prop in rx.redirect and rx.link by @ElijahAhianyo in #4389

New Features

async_db_url and rx.asession

Builtin support for async database operations using sqlmodel. Proper usage requires the following:

1. Install greenlet for sqlalchemy to use async operations.
2. Install an appropriate async-capable database driver (aiosqlite, pyscopg)
3. Set ASYNC_DB_URL in the environment that references the async db driver. This should point to the same database as specified in DB_URL, which should still be set for handling alembic migrations and for use in computed vars, etc.
4. Use async with rx.asession() as asession -- await most operations on the asession.

Async DB operations are preferred in event handlers to avoid blocking other users on the server.

Var Operations for datetime values

• add datetime var comparison operations by @Lendemor in #4406

[Wrapping React] new deps and position fields in VarData

This allows for customization and control of where hooks are rendered relative to other hooks and memoized event handlers. Deps allows for specification of vars that memoized event handlers depend on.

• add deps and position field in VarData by @Lendemor in #4518

Improvements
