Flow: Add node: aliases to Node.js libdefs (#57600)
Summary: Pull Request resolved: https://github.com/react/react-native/pull/57600 X-link: https://github.com/react/metro/pull/1783 Add `node:` aliases for every bare Node.js builtin declared by RN/Metro’s Flow libdefs. The aliases re-export the existing module types, so prefixed and unprefixed imports have the same definitions.

Incorporate timers into main Node.js lib defs and align with v24 (#55079)
Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/55079 This is an AI-assisted change to consolidate Metro's separate `node.js` file into the main Node.js library definitions and align with Node.js v24 (effectively v22) standards. **Consolidation Changes:** 1. **Incorporated Separate File** - Removed duplication - Moved definitions from `xplat/js/tools/metro/flow-typed/node.js` into main `node.js` files - Deleted the separate node.js file (no longer needed) - Both Metro and React Native now use unified definitions - Positioned alphabetically between 'tls' and 'url' modules **Timeout Class Enhancements:** 2. **Complete Timeout Class** - All timer management methods - `close()` - Cancels the timeout (added in v0.9.1) - `hasRef()` - Returns true if timer will keep Node.js running (added in v11.0.0) - `ref()` - Request timer keep Node.js running (added in v0.9.1) - `refresh()` - Refresh timer's start time (added in v10.2.0) - `unref()` - Allow Node.js to exit if timer is only active thing (added in v0.9.1) - `[Symbol.toPrimitive]` - Get numeric timer ID (added in v14.9.0) - Uses `[key: $SymbolToPrimitive]` syntax - https://nodejs.org/api/timers.html#class-timeout **Immediate Class Enhancements:** 3. **Complete Immediate Class** - Immediate timer management - `hasRef()` - Returns true if immediate will keep Node.js running (added in v11.0.0) - `ref()` - Request immediate keep Node.js running (added in v9.7.0, v8.12.0) - `unref()` - Allow Node.js to exit if immediate is only active thing (added in v9.7.0, v8.12.0) - https://nodejs.org/api/timers.html#class-immediate **Core Timer Functions:** 4. **setTimeout/setInterval/setImmediate** - Complete signatures - Generic `<TArgs: Iterable<mixed>>` for type-safe callback arguments - `setTimeout(callback, delay?, ...args)` - Returns `Timeout` - `setInterval(callback, delay?, ...args)` - Returns `Timeout` - `setImmediate(callback, ...args)` - Returns `Immediate` - All support passing additional arguments to callback - https://nodejs.org/api/timers.html#settimeoutcallback-delay-args 5. **Clear Functions** - Flexible cancellation - `clearTimeout(timeout?)` - Accepts `Timeout` or numeric ID - `clearInterval(timeout?)` - Accepts `Timeout` or numeric ID - `clearImmediate(immediate?)` - Accepts `Immediate` or numeric ID - All parameters optional (no-op if not provided) - https://nodejs.org/api/timers.html#cleartimeouttimeout **Promises API (timers/promises):** 6. **Promise-based Timers** - Async/await compatible - `setTimeout<T>(delay?, value?, options?)` - Returns `Promise<T>` (added in v15.0.0) - `setImmediate<T>(value?, options?)` - Returns `Promise<T>` (added in v15.0.0) - `setInterval<T>(delay?, value?, options?)` - Returns `AsyncIterator<T>` (added in v15.9.0) - All support AbortSignal for cancellation - https://nodejs.org/api/timers.html#timers-promises-api 7. **TimerOptions Type** - Modern options object - `ref?: boolean` - Control if timer keeps Node.js running - `signal?: AbortSignal` - Abort controller for cancellation - Type uses `Readonly<{...}>` for input immutability - https://nodejs.org/api/timers.html#timerspromisessettimeoutdelay-value-options 8. **setInterval as AsyncIterator** - Async iteration support (added in v15.9.0) - Returns `AsyncIterator<T>` instead of `Promise<T>` - Enables `for await (const value of setInterval(100, data))` patterns - Useful for periodic async operations - https://nodejs.org/api/timers.html#timerspromisessetintervaldelay-value-options **Scheduler API:** 9. **scheduler object** - Task scheduling utilities (added in v16.0.0) - `scheduler.wait(delay, options?)` - Promise-based delay (alternative to setTimeout) - `scheduler.yield()` - Yield to event loop (microtask yield) - Object marked as `Readonly<{...}>` for immutability - https://nodejs.org/api/timers.html#timerspromisesschedulerwaitdelay-options **Type Safety Improvements:** 10. **Readonly Input Types** - Applied consistently - `TimerOptions`: `Readonly<{ref?, signal?}>` - `scheduler` object: `Readonly<{wait, yield}>` - Allows passing readonly types safely (inputs should be readonly) 11. **Generic Type Parameters** - Type-safe callbacks - Timer functions: `<TArgs: Iterable<mixed>>` for variadic args - Promises API: `<T>` for resolved value types - Default generic: `<T = void>` for setInterval iterator 12. **Export Type Aliases** - Better developer experience - `Timeout` and `Immediate` exported as types from module - Consistent `timers$` prefix for internal types - Clean module exports without duplication **Symbol Support:** 13. **Symbol.toPrimitive** - Convert Timeout to number (added in v14.9.0) - Allows implicit conversion: `Number(timeout)` or `+timeout` - Returns the numeric timer ID - Flow syntax: `[key: $SymbolToPrimitive]: () => number` - https://nodejs.org/api/timers.html#timeoutsymboltoprimitive **Flow Limitations:** 14. **Symbol.dispose not included** - Explicit resource management - `[key: $SymbolDispose]: () => void` is commented out - Node.js added Symbol.dispose in v18.18.0, v20.4.0 - Flow doesn't fully support this symbol yet or has issues with multiple symbol-keyed properties - Will be enabled when Flow support improves - https://nodejs.org/api/timers.html#timeoutsymboldispose **References:** - Node.js timers module docs: https://nodejs.org/api/timers.html - TC39 Explicit Resource Management: https://github.com/tc39/proposal-explicit-resource-management Changelog: [Internal] --- > Generated by [Confucius Code Assist (CCA)](https://www.internalfb.com/wiki/Confucius/Analect/Shared_Analects/Confucius_Code_Assist_(CCA)/) [Confucius Session](https://www.internalfb.com/confucius?host=devvm45708.cln0.facebook.com&port=8086&tab=Chat&session_id=1a3aa26e-e5a9-11f0-8d47-71a4a90f0494&entry_name=Code+Assist), [Trace](https://www.internalfb.com/confucius?session_id=1a3aa26e-e5a9-11f0-8d47-71a4a90f0494&tab=Trace) Reviewed By: vzaidman Differential Revision: D89944814 fbshipit-source-id: 38c1773d1a3591ef9f123681655720d17e7e53bb |
