Summary: I noticed that after the typescript upgrade, I got several weird positives from ESLint (like unused parameters in a type definition, which are obviously always unused, e.g. `type onClick = (e: Event) => void`). After some investigation, it turned out these warnings are generated by eslint, but that those rules should be performaned by typescript/eslint instead. For future reference to which rules this applies: https://github.com/typescript-eslint/typescript-eslint/blob/master/packages/eslint-plugin/README.md#extension-rules Updated the config, and while at it, fixed all warnings in our codebase, except for `react-hooks/exhaustive-deps` warnings, since those require semantic changes. This reduces the amount of eslint warnings from 86 to 39. Reviewed By: passy Differential Revision: D23905630 fbshipit-source-id: 0557708fd9ec6b17840a3c191e7d3baf225bdf23
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
