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 of ui.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 for ui.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 passing hide_drawn_items=True to ui.leaflet.

  • Unify declaration of third-party dependencies (#2991 by @falkoschindler, @rodja)

    ⚠️ BREAKING: This release deprecates the libraries, extra_libraries and exposed_libraries parameters for subclassing ui.element. It introduces a new dependencies 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 the validation argument and property is not None. 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 to ui.run. Furthermore, you can specify the individual routes by setting core.app.docs_url, core.app.redoc_url, and core.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 is None. If you need to check if the socket connection is established, use client.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.

    • ui.run_javascript() and related methods:
      The respond and check_interval parameters are not needed anymore and got removed.
    • context:
      The get_slot_stack() method has been replaced with the slot_stack property.
      The get_slot() method has been replaced with the slot property.
      The get_client() method has been replaced with the client property.
    • Layout elements ui.header, ui.footer, ui.drawer, ui.left_drawer and ui.right_drawer:
      Nesting top level layout elements now raises a RuntimeError.
    • Storage:
      NiceGUI no longer migrates files from the system's default encoding to UTF-8. This was only a temporary migration. All storage files should be encoded with UTF-8 by now.
    • ui.aggrid:
      The method call_api_method has been replaced with run_grid_method.
      The method call_column_method has been replaced with run_column_method.
    • ui.chart is now ui.highchart.
    • ui.open has been replaced with ui.navigate.to.
    • ui.add_style has been removed. Use ui.add_css, ui.add_scss, or ui.add_sass instead.
