 # Changelog

+## 2026-01-25 - 1.5.0 - feat(streaming)
+add real-time streaming (MongoDB change streams & S3 bucket watchers) with WebSocket subscriptions and activity stream UI
+
+- Server: add ChangeStreamManager to manage MongoDB change streams and S3 BucketWatcher subscriptions, handle subscription lifecycle, activity ring buffer and push events via TypedSocket.
+- API: introduce streaming TypedRequest interfaces and register new handlers (subscribeMongo/unsubscribeMongo, subscribeS3/unsubscribeS3, subscribeActivity/unsubscribeActivity, getRecentActivity, push events).
+- Client: add ChangeStreamService (TypedSocket connection, reconnection, RxJS subjects) and integrate into tsview-app, mongo and S3 browsers to show live status, change counters and refresh content on updates.
+- UI: add new Activity Stream component (tsview-activity-stream), Activity tab and navigation, plus visual indicators (Live/Offline, change badges, auto-scroll and filters).
+- Dependencies & plugins: add @api.global/typedsocket and @push.rocks/smartrx, bump @push.rocks/smartbucket; expose smartrx/typedsocket in plugins for server and web bundles.
+- Docs: update readme.hints.md with Real-Time Streaming architecture, interfaces and dependency notes.
+
+## 2026-01-25 - 1.4.0 - feat(web)
+add database overview panel, collection overview and resizable panels; show/hide system databases; use code editor with change-tracking in document view; add getDatabaseStats API and typings; enable overwrite for S3 uploads
+
+- Add backend handler getDatabaseStats + request/response typings (IReq_GetDatabaseStats, IDatabaseStats) and ApiService.getDatabaseStats()
+- New UI component tsview-mongo-db-overview to show database statistics (collections, objects, avg size, data/storage size, indexes)
+- Collections list: added an "Overview" entry that opens the DB overview when selected
+- Sidebar: context menu option to show/hide system databases (admin/config/local) and database collapse-on-click behavior
+- Resizable layout improvements: draggable dividers added for sidebar, Mongo editor panel and S3 preview panel (persisted via local state variables)
+- Document editor: switch to dees-input-code, track original content and unsaved changes, add discard/save flow and improved save handling
+- S3 handlers: fastPut calls now pass overwrite: true to allow replacing existing keys
+- Minor dependency bumps: @git.zone/tstest and @design.estate/dees-catalog
+
+## 2026-01-25 - 1.3.0 - feat(s3)
+add S3 create file/folder dialogs and in-place text editor; export mongodb plugin
+
+- Add mongodb dependency and export mongodb in ts/plugins.ts so ObjectId can be reused from plugins.
+- Update handlers.mongodb to use plugins.mongodb.ObjectId instead of requiring mongodb directly.
+- UI: Add create-file and create-folder dialogs and context-menu entries in tsview-app, tsview-s3-columns, and tsview-s3-keys to create objects (folders use a .keep object).
+- Implement client-side helpers to determine content type/default content and call apiService.putObject with base64 content when creating files/folders.
+- S3 preview: embed dees-input-code editor for text files with language detection, unsaved-changes indicator, Save/Discard flows, and saving via apiService.putObject.
+- Various styling and UX improvements for dialogs, buttons, and editor states.
+
+## 2026-01-25 - 1.2.0 - feat(s3,web-ui)
+add S3 deletePrefix and getObjectUrl endpoints and add context menus in UI for S3 and Mongo views
+
+- Add server-side TypedHandlers: deletePrefix and getObjectUrl (ts/api/handlers.s3.ts)
+- Add request/response interfaces IReq_DeletePrefix and IReq_GetObjectUrl (ts/interfaces/index.ts)
+- Add client API methods deletePrefix and getObjectUrl (ts_web/services/api.service.ts)
+- Introduce context menu actions (DeesContextmenu) across UI: bucket/database/collection/document/folder/file actions including open, copy path, delete, download and duplicate (ts_web/elements/tsview-app.ts, tsview-mongo-collections.ts, tsview-mongo-documents.ts, tsview-s3-columns.ts, tsview-s3-keys.ts)
+- Switch from inline delete buttons to contextual menus for safer UX; implement downloads via data URLs returned by getObjectUrl and deletion of S3 prefixes (folders)
+
+## 2026-01-25 - 1.1.3 - fix(package)
+update package metadata
+
+- metadata-only change; no source code changes
+- current version 1.1.2 → recommended patch bump to 1.1.3
+
 ## 2026-01-25 - 1.1.2 - fix(package)
 apply minor metadata-only change (one-line edit)

+## Real-Time Streaming (v1.5.0+)
+
+### Architecture
+- `ts/streaming/` - Backend streaming infrastructure
+  - `classes.changestream-manager.ts` - Manages MongoDB and S3 watchers
+  - `interfaces.streaming.ts` - TypedRequest interfaces for subscriptions
+- `ts_web/services/changestream.service.ts` - Frontend WebSocket client
+
+### MongoDB Change Streams
+- Uses native MongoDB Change Streams via `SmartdataDb.mongoDbClient`
+- Subscription per collection: `db/collection`
+- Events: insert, update, delete, replace, drop
+
+### S3 Change Detection
+- Uses `@push.rocks/smartbucket` BucketWatcher (polling-based)
+- Polling interval: 5 seconds
+- Events: add, modify, delete
+
+### Frontend Components
+- `tsview-activity-stream.ts` - Combined activity view with filtering
+- MongoDB/S3 browsers auto-subscribe to current resource
+- Visual indicators for "Live" status and recent change count
+
+### Key Streaming Interfaces
+```typescript
+// Subscribe to collection changes
+IReq_SubscribeMongo: { database, collection } -> { success, subscriptionId }
+
+// Subscribe to bucket changes
+IReq_SubscribeS3: { bucket, prefix? } -> { success, subscriptionId }
+
+// Subscribe to activity stream (all changes)
+IReq_SubscribeActivity: {} -> { success, subscriptionId }
+
+// Server pushes changes to subscribed clients
+IReq_PushMongoChange: { event: IMongoChangeEvent } -> { received }
+IReq_PushS3Change: { event: IS3ChangeEvent } -> { received }
+IReq_PushActivityEvent: { event: IActivityEvent } -> { received }
+```
+
+### Dependencies Added
+- `@api.global/typedsocket` - WebSocket client/server
+- `@push.rocks/smartrx` - RxJS utilities
