Bowtie Versions Save

Added

• Start of Authentication API
• Better interoperability with Flask
• Views have a layout attribute that is run a build time, which can save time at serve time.

Breaking

• Apps layout now happens in global state or in layout functions.
• Remove server.py and templates, bundle.js{,.gz} is placed directly in build directory.
• load and subscribe are decorators now, simplifying usage.
• Sidebar now defaults to False.
• Removed respond function, moved feature to subscribe.

Added

• Minimum node version check.

Fixed

• v0.10.0 had a bunch of extra junk generated in it.

Added

• Mostly internal changes so that dynamic layout can be supported.
• Dropped Python 3.5 compatibility.
• Added Python 3.7 support. (#233)
• Update random walk so it can be used with multiple users. (#126)
• Views now have a border attribute for specifying a margin around the whole page, defaults to 7 pixels.
• Add multiple components to a cell or span, for example:

  app = App() app[0, 0] = button app[0, 0] += button2 Or app = App() app[0, 0] = button, button2

• Moved link component from control to html module

Fixed

• Bug with rebuilding apps due to caching problems.
• Bug when refreshing apps with date pickers, the stored state wasn't being restored correctly.

Breaking

• Captions in controllers have been removed, they can be replaced with HTML components.

Added

• Upgraded to webpack 4, users shouldn't see much of a difference other than slightly improved build times.

Fixed

• Readthedocs wasn't rendering due to type hints, fixed with conda.

Added

• Jupyter integration.
• Basic HTML components: Div and H1-H6.
• Add multiple components into a single span/cell. This can be useful for adding multiple control or html elements into a single cell.

Breaking

• Drop support for Python 2.
• Moved Markdown widget to HTML components.

Fixed

• Error if only the gzipped bundle is available.

Added

• Improved widget handling, now use a dict to store components instead of parsing code. Makes it possible to subscribe to events with expressions for the component.

• Support Ant theme to customize all Ant components, added in the App class.
• Vertical option for slider. (#204)

Breaking

• row_end and column_end are now exclusive instead of inclusive.
• Simplified the add function in favor of the new getitem functionality, which is easier to use and familiar to Python programmers.

Added

• Docstring examples of sizing components.
• More checks to ensure adding components works as expected.

Fixed

• Bug which incorrectly tracked which parts of the grid were occupied by widgets.

Added

• Removed node and webpack dependencies, the only dependency is yarn.
• Added a run command that simply combines build and serve together.
• Smarter build process that saves time on subsequent builds.
• Handle scheduled tasks when running with debug=True (#185)
• Improve the Docker experience and docs.
• Always use the latest compiled bundle.

Breaking

• Instead of building the app by running app.build() you simply return the App instance. See the quick start guide for an example.
