Radix 3.0 by Lendemor in https://github.com/reflex-dev/reflex/pull/3159

New Public API for wrapping Components

To make wrapping components easier and less error prone, the following functions should be overridden when wrapping components:

* `add_style` - return an `rx.style.Style` for default component styles
* `add_imports` - return a dictionary of `{"library-name0.5.0": {"tag1", "tag2", "tag3"}}` of required imports -- it will automatically be merged with the other component imports.
* `add_hooks` - return a list of javascript snippets that will go inside the component function -- it will be deduped automatically with any other hooks
* `add_custom_code` - return a list of javascript snippets that will go inside the module for each page the component is included in.

With these new methods, Reflex will internally call them for each parent class your component inherits from, so there is no need to call `super().add_*` or do any merging yourself.

* [REF-2523] Implement new public Component API by masenf in https://github.com/reflex-dev/reflex/pull/3203
* add_style api by Lendemor in https://github.com/reflex-dev/reflex/pull/3202

`State.setvar(var_name, value)`

A less magic version of the automatic `State.set_x` setter functions which accept the `var_name` as a string.

* [REF-2273] Implement .setvar special EventHandler by masenf in https://github.com/reflex-dev/reflex/pull/3163

Experimental Toast Component

python
def try_some_toast():
return rx.fragment(
rx.button("🥂", on_click=rx._x.toast.info("Cheers"), variant="outline"),
rx._x.toast.provider(),
)


* add toast component by Lendemor in https://github.com/reflex-dev/reflex/pull/3186
Generic `.throttle` and `.debounce` for all Event types

python
class ThrottleState(rx.State):
last_event: datetime.datetime = datetime.datetime.now()

def handle_mouse_move(self):
self.last_event = datetime.datetime.now()

def throttle_example():
return rx.box(
ThrottleState.last_event,
background_color=rx.color("red", 7),
width="500px",
height="500px",
on_mouse_move=ThrottleState.handle_mouse_move.throttle(500), one event every 500ms
)


* Implement `throttle` and `debounce` as event actions by masenf in https://github.com/reflex-dev/reflex/pull/3091

`rx.container` new prop `stack_children_full_width`

For a nice streamlit-like wide layout, use the following snippet:

python
def index():
return rx.container(
rx.vstack(content()),
stack_children_full_width=True,
)


This will cause all vstack/hstack children and most stack child components to have `width="100%"` automatically, which provides a nice aesthetic for many apps without applying CSS to individual components.

* [REF-2574] Default width for Stack (+children) and default padding for container by masenf in https://github.com/reflex-dev/reflex/pull/3104

Release Notes

SASS and SCSS

Thanks to KronosDev-Pro, reflex can now compile your SASS and SCSS files for you! Simply reference a local SASS/SCSS file in the stylesheets key-word argument for rx.App. You need to have libsass installed.

* [IMPL] - added support for sass and scss stylesheet languages by KronosDev-Pro in https://github.com/reflex-dev/reflex/pull/4292
* add libsass to the dev deps by adhami3310 in https://github.com/reflex-dev/reflex/pull/4982

Bun

We used to be using bun as a default for installation, and now we're using it as a runtime as well. In most cases it should work fine, but if it doesn't, you should install `node` in your global system.

This also removes fnm/npm automatic download from reflex and will cut down on the time for new system installs.

* double down on bun over fnm/npm by adhami3310 in https://github.com/reflex-dev/reflex/pull/4906

Granian

We are starting to migrate to Granian as the ASGI that ships with default with Reflex. You can test it with REFLEX_USE_GRANIAN=1. For now there will be some bugs, but we will be resolving them as time comes. Hopefully by 0.8.0 we would have deprecated uvicorn and moved primarily to Granian.

In the same change, you can also run `reflex` from any asgi compliant program, for example:


uvicorn your_app_name.your_app_name:app --factory


* Remove app_module_for_backend by masenf in https://github.com/reflex-dev/reflex/pull/4749
* granian all the way by adhami3310 in https://github.com/reflex-dev/reflex/pull/4994
* move granian to the sidelines by adhami3310 in https://github.com/reflex-dev/reflex/pull/5010

Specify multiple env files

You can pass multiple files (separated by : on linux, ; on windows) for the ENV_FILE environment variable.

* Allow multiple env_file to be specified, split on os pathsep by masenf in https://github.com/reflex-dev/reflex/pull/4993

NextJS downgrade :(

Due to issues we're having with turbopack, we're temporarily downgrading to an earlier version of nextJS 15 until the issues get fixed.

New features

`,` and `_` options for formatted numbers

python
class State(rx.State):
large_number: float = 123123213.21321312

rx.text(f"{State.large_number:,.3f}")


* add `,` and `_` operations by adhami3310 in https://github.com/reflex-dev/reflex/pull/4950

Add raw headers to router headers

python
class State(rx.State):
rx.event
def on_event(self):
print(self.router.header.raw_headers) read only header mapping


* add raw headers to headers by adhami3310 in https://github.com/reflex-dev/reflex/pull/4958

Expose SVG elements at the el level

We are trying to reach parity where all acceptable HTML elements are exposed at the .el scope, now you can use `text`, `line`, `circle`, `ellipse`, `rect`, `polygon`, `path`, `stop`, `linear_gradient`, `radial_gradient`, `defs`.

* expose svg elements at the el level by adhami3310 in https://github.com/reflex-dev/reflex/pull/4962

New .get var operation

Useful accessing State vars typed as dicts/dataclasses/pydantic modedls to provide a default if the key is possibly absent.

python
class State(rx.State):
field: rx.Field[dict[str, int]] = rx.field({"josh": 96, "john": 32})

State.field.get("joseph", 0)

**Full Changelog**: https://github.com/reflex-dev/reflex/compare/v0.7.2...v0.7.3

What's Changed

Deprecated instantiating components through Component.__init__

You should have probably been doing `.create`.

* deprecate Component __init__ by adhami3310 in https://github.com/reflex-dev/reflex/pull/4904

Overwrite rx.serializer

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

python
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 https://github.com/reflex-dev/reflex/pull/4888

Use .f with Vars

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

python
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 https://github.com/reflex-dev/reflex/pull/4855

**Full Changelog**: https://github.com/reflex-dev/reflex/compare/v0.7.1...release/reflex-0.7.2

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 https://github.com/reflex-dev/reflex/pull/4790

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

* add capitalize and title var operations by adhami3310 in https://github.com/reflex-dev/reflex/pull/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 https://github.com/reflex-dev/reflex/pull/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 https://github.com/reflex-dev/reflex/pull/4827
