Summary: Added demo to show how DataSource can power charts using event sampling and smart windowing. A more experimental application: use dataSource to power some charts, that leverages the events emitted from an datasource that is continuously being appended: - incoming events are downsampled 1 in 100 to build up the bottom window - incoming events are not downsampled to render the topwindow, but since datasource views will ignore events outside the window, things will stay pretty responsive when a window is selected (without a window, the downsampled dataset is used as source for top chart as well). Compared to a naive (well still slightly optimised with useFastArray) implementation that throws all incoming event in a big array, it performs > 20 times faster (see difference in amount of events processed) Reviewed By: passy Differential Revision: D28474409 fbshipit-source-id: 6a7973d1ade3053b1d6c8f72069697d96b1ef4fd
flipper-plugin
flipper-plugin is the dependency used by all modern Flipper plugins (project "Tommy").
For background: https://fb.quip.com/YHOGAnaPqAVJ
flipper-plugin is to be used as dev and peer dependency of all Flipper plugins. It provides:
- (TODO) Standard API's to interact with Flipper, such as the client connection.
- (TODO) Standard components to organize the UI
- (TODO) Testing utilities
API's provided by flipper-plugin are documented at fbflipper.com (TODO).
There should normally be no need to install flipper-plugin as dependency.
Rather, plugins should be scaffolded using npx flipper-pkg init (TODO) as documented here
