Summary: Let's ban the non null assertion syntax `maybeNull!` as it is unsafe and can cause unexpected behavior. Ideally this should be an error or require a comment explaining why the value cannot be nullish. Though, there are 468 occurrences around the codebase and it is not worth it to manually go around fixing it now. Thus I used a warn to still warn developers to avoid the use where possible. Last week I spend over an hour on debugging something where the code was null-asserted as the developer thought the value could never be null while in reallity it could. Adding a runtime check in this case sounds reasonable. rule docs https://typescript-eslint.io/rules/no-non-null-assertion/ Reviewed By: nikoant Differential Revision: D45773327 fbshipit-source-id: 9e8a40af353ce979f469ffaedd8e777d72500dab
Flipper Desktop
This folder contains everything to run the Flipper 'Desktop', that is, the UI which you use to interact with the device / app under debug.
Packages provided here:
- flipper-common: utilities & types shared between client, server, flipper-plugin
- flipper-server-core: all device & client management goes in here. Basically flipper's backend
- flipper-ui-core: all UI goes in here, as far as it doesn't depend on Electron
- flipper-ui-electron: the Electron app, will load server-core and ui-core, and glue them together, providing implementations for some electron * specific stuff like dialgos
- flipper-server: A node process hosting flipper-server-core, that can be connected to over websockets. And probably can serve a browser version of the UI as well.
- flipper-ui-browser: thin wrapper around flipper-ui-core, providing some browser specific behavior / stubs.
- flipper-dump: (might remove later), but want to hack a quick and dirt flipper dump in here, as alternative way to test flipper-server-core.
- flipper-plugin: The flipper SDK used by plugins. Exposes all API's that can be used by plugins
- pkg: CLI tool to manage building flipper plugins
- pkg-lib
- plugin-lib
- babel-transformer
- doctor
- eslint-plugin-flipper
