New features and enhancements, breaking changes and migration guide
This major release introduces several new features and enhancements, as well as breaking changes. We always try to keep breaking changes to a minimum, guide you through the migration process using deprecation warnings, and provide migration instructions. Please read the following release notes carefully to understand the changes and adapt your code accordingly before upgrading.
-
Semantic versioning
NiceGUI 2.0 starts to implement semantic versioning, which means that we will follow the MAJOR.MINOR.PATCH versioning scheme. This release is a major version because it introduces breaking changes. We will increment the MAJOR version for breaking changes, the MINOR version for new features and enhancements, and the PATCH version for bug fixes.

Fix Quasar's layout rules for
ui.card
that remove children's borders and shadows (#726, #1295, #2265, #2301, #3444 by @miqsoft, @v479038280, @ghbm-itk, @falkoschindler)⚠️ BREAKING: Quasar's QCard, the foundation of NiceGUI's
ui.card
, usually comes without any padding and requires nested card sections wrapping the actual content. NiceGUI simplified the use of cards by adding padding, flex layout and gaps automatically. But because a QCard also removes the outer-most borders and shadows of its children, this caused unexpected results in certain cases. NiceGUI 2.0 fixes the behavior ofui.card
by disabling Quasar's respective CSS rules. -
Improve the API of
ui.table
(#2633, #2731, #3263, #3264, #3525 by @bojh, @rohitsathish, @tmlmt, @falkoschindler)⚠️ BREAKING: The API for adding and removing rows in a
ui.table
has been improved. Passing rows as multiple arguments has been deprecated. Now these methods expect lists of rows.The
column
argument forui.table
is optional now. If not provided, the columns are infered from the first row.A new
update_from_pandas
method has been introduced to update rows and columns from a new dataframe.A new
column_defaults
parameter has been introduced to allow specifying some properties for all columns at once. -
Improve support for drawing items in
ui.leaflet
(#2422, #3586 by @joseph-fidelis, @falkoschindler)⚠️ BREAKING: The
ui.leaflet
element used to remove drawn items and required the user code to add new layers to the map for visualization. Now such items remain visible by default. This new behavior can be disabled by passinghide_drawn_items=True
toui.leaflet
. -
Unify declaration of third-party dependencies (#2991 by @falkoschindler, @rodja)
⚠️ BREAKING: This release deprecates the
libraries
,extra_libraries
andexposed_libraries
parameters for subclassingui.element
. It introduces a newdependencies
parameter to be used instead. New examples "Custom Vue Component" and "Signature Pad" demonstrate how to use NPM and this parameter for integrating custom components based on third-party JavaScript libraries. -
Reserve bottom space in validation elements for error messages (#2484, #2492, #2738, #3013, #3446, #3660 by @akai-1024, @huche6, @atticus-lv, @rodja, @falkoschindler)
⚠️ BREAKING: UI elements with input validation like
ui.input
used to omit the bottom space for a potential error message. This caused a layout jump when the first error occurred. This release fixes this issue be reserving the space by default whenever thevalidation
argument and property is notNone
. You can disable this behavior using the "hide-bottom-space" prop. -
Remove
ui.timer
objects from UI hierarchy after they are finished (#3626, #3647 by @fwerner, @rodja)Especially one-shot timers are now removed from the UI hierarchy after their callback has been executed. This avoids a potential memory leak.
-
Disable FastAPI docs by default (#3570, #3589 by @Yuerchu, @python-and-fiction, @rodja)
⚠️ BREAKING: NiceGUI apps used to automatically serve FastAPI docs at /docs, /redoc, and /openapi.json. This behavior has been disabled. You can enable it by passing
fastapi_docs=True
toui.run
. Furthermore, you can specify the individual routes by settingcore.app.docs_url
,core.app.redoc_url
, andcore.app.openapi_url
. -
Make
client.ip
available before socket connection is established (#2399, #3287, #3445 by @rodja, @falkoschindler)⚠️ BREAKING: The client's IP is now already available before the page built and is returned to the client. On the auto-index page the
client.ip
property isNone
. If you need to check if the socket connection is established, useclient.has_socket_connection
instead. -
Remove and update deprecated APIs (#3648 by @falkoschindler)
⚠️ BREAKING: Several deprecated APIs have been removed. The remaining deprecations will show warnings including the version when they will be removed. Please update your code accordingly.
