Release 0.2.8

0.2.8 (2023-12-10)


  • On mobile layouts, automatically close sidebars when submit is clicked. Thank you @seanbearden for the issue.
  • New examples in the documentation.
  • Added some new examples to README.


  • Set image component width to 100%.
  • Fix: If input is None, it's not automatically transformed.

0.2.7 (2023-10-18)


  • New component: Table
    • Fast components are callable to update attributes. For example, to update the page_size attribute of Table, do Table(page_size=20). At the same time, Fast Components can also be used as non-callable objects.
  • Pandas DataFrame is rendered as a Table.
  • "About" button displays the function docstring in parse markdown. New utility function to extract function docstring has been incorporated for this feature. This is, however, still experimental.
  • Documentation upates, new "Usage Patterns" page.
  • New tests.
  • Fast Dash now supports Python 3.11.


  • Support for Python 3.7 has been deprecated.

0.2.6 (2023-09-04)


  • New chat component! Setting the output data type to Chat and returning a dictionary displays a chat component.
  • Introduced a transformation step before passing inputs to the callback. This allows converting non-native inputs to native data types. For example, passing a PIL.Image as input data tyoe hint doesn't need converting it to a base64 string.
  • Errors are displayed as notifications.
  • Updated documentation and tests.

0.2.5 (2023-08-13)


  • Fix: update_live is automatically set to True if the callback function doesn't require any inputs.

0.2.4 (2023-08-12)


  • Improve responsiveness on mobile views.
  • outputs argument overrides callback function output hints.
  • Improve pytest coverage.

0.2.3 (2023-08-01)


  • Dash components can be used as type hints directly. They are converted to Fast components during app initialization.
  • Added a mosaic layout example to README.
  • dash can be imported from fast_dash like this: from fast_dash import dash.

0.2.2 (2023-07-26)


  • New example: Chat over docs with Embedchain.


  • Squashed a bug that was preventing the submit and reset buttons to sync with each other. The result is a more stable deploy using callback context.

0.2.1 (2023-07-23)


  • Infer output labels from the callback function or specify the `output_labels`` argument
  • Show overlay when loading outputs
  • Use dmc.Burger icon instead of open, close icons. Allows for a clearner sidebar open/close UX
  • New examples


  • [Bug] Components are now initialized with the desired height
  • Sidebar collapse burger is not supported in minimal layout
  • Replace branding text with icon
  • New pytests to improve coverage

  • Introduce Fast Dash decorator (fastdash) for automatic and quick deployment.
  • Autoinfer input and output components from type hints and default values.
  • Autoinfer title and subheader by inspecting the callback function.
  • New test cases.
  • Modified documentation layout and content.
  • New GitHub Actions workflow to publish documentation only.

0.1.6 (2022-05-09)

  • Navbar and footer are not thinner than before, which makes them less distracting ;)
  • They no longer stick to the top and bottom respectively. Scrolling on the page makes the navbar dissappear!
  • Update live: New live update option! Setting the argument update_live=True removes Submit and Clear buttons. Any action updates the app right away.
  • New spinners: Finally, Fast Dash now has loading spinners to indicate loading outputs. This comes in handy when executing long running scripts.

0.1.5 (2022-04-02)

  • Add examples: Object detection, molecule 3D viewer and UI updates to the existing examples.
  • Easier fastification: Fastify now allows using a complete Dash component as the first argument.
