November 2025 focused on strengthening attachment workflows and modular architecture in powersync-js. Delivered enhanced Todo app attachment handling with Expo blob compatibility, refined attachment row mapping, and streamlined download/upload flows. Refactored the attachments module into a cross-platform common package with a Node.js export structure, reorganized storage adapters, and improved the AttachmentQueue. These changes reduce maintenance overhead, improve user experience for attachments, and set the foundation for broader cross-platform storage support across web and Node.js.

Month 2025-10 focused on delivering robust attachment syncing capabilities and flexible storage configuration in powersync-js. Implemented a dedicated AttachmentService, migrated storage to a syncing service, introduced updateHook support, and enhanced watchAttachments with asynchronous callbacks. Improved resource management for the active attachments listener, added documentation clarifications, and enabled user-defined storage adapter paths for IndexedDB and Node file systems. These changes increase reliability, scalability, and configurability of file synchronization workflows, delivering tangible business value by reducing sync friction and enabling deployment-time storage customization.
