…#49957) Summary: Pull Request resolved: facebook#49957 ## Changes This diff introduces the api for "main queue modules" into turbo modules. This will occur occurs before any rendering. ## Rationale Rendering can now include main -> js sync calls. If we allow js -> main sync calls during rendering, react native can deadlock. With this diff, we can move the js -> main sync calls to before any rendering happens. ## APIs **Buck API:** Plugin: ``` react_module_plugin_providers( name = "AccessibilityManager", native_class_func = "RCTAccessibilityManagerCls", unstable_requires_main_queue_setup = True, ) ``` **OSS API:** [codegenConfig](https://reactnative.dev/docs/the-new-architecture/using-codegen) in package.json: ``` "codegenConfig": { "name": "<SpecName>", "type": "<types>", "jsSrcsDir": "<source_dir>", "android": { "javaPackageName": "<java.package.name>" }, "ios": { "modules": { "AccessibilityManager": { "className": "RCTAccessibilityManager", "unstableRequiresMainQueueSetup": true } } } }, ``` Changelog: [iOS][Added] Introduce unstableRequiresMainQueueSetup api to modules Differential Revision: D70413478 Reviewed By: cipolleschi
…#50040) Summary: Pull Request resolved: facebook#50040 This diff implements main queue module setup. Sometimes, people need to capture uikit things, and use them from javascript. In those cases, people can write main queue modules. These modules will be eagerly initialized on the main queue, during react native init. ## On Necessity **Sync** dispatches to the main thread from the js thread can deadlock react native. And **async** dispatches to the main thread from the js thread sometimes might not be enough: it could lead to flickery rendering. So, we need to allow people to capture ui thread things, before any js executes. ## Caveat This api is dangerous and discouraged. All react native surfaces will pay the cost of one surface introducing a main queue module. It could also slow down common/critical interactions in your app, if you're not careful. We will introduce performance logging for this infrastructure. So that we can monitor and file tasks, when main queue module init starts taking "too long."
