PostHog/posthog-js

Context This is the WeChat Mini Program runtime scope split out of #2223. WeChat Mini Programs do not provide the browser APIs expected by posthog-js or posthog-js-lite. They use platform-specific APIs such as wx.request, wx storage, and Mini Program lifecycle hooks. Proposed scope Provide an officially supported PostHog SDK for the WeChat Mini Program runtime, preferably built on @posthog/core. MVP capabilities Event capture User identification and reset Persistent and session super properties Session tracking Persistent event queue Batching, retries, and explicit flushing using wx.request Persistence using WeChat storage APIs Appropriate flushing during Mini Program lifecycle transitions Out of scope for the initial SDK Browser DOM-based features such as web autocapture, heatmaps, and session replay require separate Mini Program-specific designs and should not be implied by the MVP. Acceptance criteria A supported package is published from this repository Capture, identify, rese

Bug description:** When using posthog-react-native in a bare React Native project (without Expo) with Hermes enabled, the Metro serializer provided by the SDK (createPostHogMetroSerializer) crashes during bundling with: Error: Chunk ID was not found in the bundle. This makes it impossible to upload source maps for error tracking in non-Expo React Native apps. The issue is in three files within the posthog-react-native package: File 1: dist/tooling/utils.js — determineDebugIdFromBundleSource function The SDK generates a code snippet that stores the chunk ID using a variable as the key (e._posthogChunkIds[n] = "..."), but the regex that searches for it in the bundled output only looks for string literals or numbers as keys — it never matches the variable [n], so the chunk ID is never found. File 2: dist/tooling/posthogMetroSerializer.js — createPostHogMetroSerializer function Even after fixing the regex above, the serializer finds the placeholder string "__POSTHOG_CHUNK_ID__" but
