 # Changelog

+## 2025-11-20 - 4.3.0 - feat(listing)
+Add memory-efficient listing APIs: async generator, RxJS observable, and cursor pagination; export ListCursor and Minimatch; add minimatch dependency; bump to 4.2.0
+
+- Added memory-efficient listing methods on Bucket: listAllObjects (async generator), listAllObjectsObservable (RxJS Observable), createCursor (returns ListCursor) and listAllObjectsArray (convenience array collector).
+- New ListCursor class (ts/classes.listcursor.ts) providing page-based iteration: next(), hasMore(), reset(), getToken()/setToken().
+- Added glob matching helper findByGlob(pattern) using minimatch (exported via plugins.Minimatch).
+- Exported ListCursor from ts/index.ts and exported Minimatch via ts/plugins.ts.
+- Added minimatch dependency in package.json and bumped package version to 4.2.0; increased test timeout to 120s.
+- Updated tests to read S3_SECRETKEY, S3_PORT and to assert bucket name from env (test/test.node+deno.ts, test/test.trash.node+deno.ts).
+- No breaking changes: new APIs are additive and existing behavior preserved.
+
+## 2025-11-20 - 4.2.0 - feat(listing)
+Add memory-efficient listing with async generators, RxJS observables, and cursor pagination for huge buckets
+
+**New Memory-Efficient Listing Methods:**
+
+**Async Generator (Recommended for most use cases):**
+- `Bucket.listAllObjects(prefix?)` - Stream object keys one at a time using `for await...of`
+- `Bucket.findByGlob(pattern)` - Find objects matching glob patterns (e.g., `**/*.json`, `npm/packages/*/index.json`)
+- Memory efficient, supports early termination, composable
+
+**RxJS Observable (For complex reactive pipelines):**
+- `Bucket.listAllObjectsObservable(prefix?)` - Emit keys as Observable for use with RxJS operators (filter, map, take, etc.)
+- Perfect for complex data transformations and reactive architectures
+
+**Cursor Pattern (For manual pagination control):**
+- `Bucket.createCursor(prefix?, options?)` - Create cursor for explicit page-by-page iteration
+- `ListCursor.next()` - Fetch next page of results
+- `ListCursor.hasMore()` - Check if more results available
+- `ListCursor.reset()` - Reset to beginning
+- `ListCursor.getToken()` / `ListCursor.setToken()` - Save/restore pagination state
+- Ideal for UI pagination and resumable operations
+
+**Convenience Methods:**
+- `Bucket.listAllObjectsArray(prefix?)` - Collect all keys into array (WARNING: loads all into memory)
+
+**Benefits:**
+- ✅ Memory-efficient streaming for buckets with millions of objects
+- ✅ Three patterns for different use cases (generators, observables, cursors)
+- ✅ Support for early termination and incremental processing
+- ✅ Glob pattern matching with minimatch
+- ✅ Full TypeScript support with proper types
+- ✅ Zero breaking changes - all new methods
+
+**Dependencies:**
+- Added `minimatch` for glob pattern support
+
+**Files Changed:**
+- `ts/classes.bucket.ts` - Added all listing methods
+- `ts/classes.listcursor.ts` - NEW: Cursor implementation
+- `ts/plugins.ts` - Export Minimatch
+- `ts/index.ts` - Export ListCursor
+- `test/test.listing.node+deno.ts` - NEW: Comprehensive listing tests
+- `package.json` - Added minimatch dependency
+
+## 2025-11-20 - 4.1.0 - feat(core)
+Add S3 endpoint normalization, directory pagination, improved metadata checks, trash support, and related tests
+
+- Add normalizeS3Descriptor helper to sanitize and normalize various S3 endpoint formats and emit warnings for mismatches (helpers.ts).
+- Use normalized endpoint and credentials when constructing S3 client in SmartBucket (classes.smartbucket.ts).
+- Implement paginated listing helper listObjectsV2AllPages in Directory and use it for listFiles and listDirectories to aggregate Contents and CommonPrefixes across pages (classes.directory.ts).
+- Improve MetaData.hasMetaData to catch NotFound errors and return false instead of throwing (classes.metadata.ts).
+- Export metadata and trash modules from index (ts/index.ts) and add a Trash class with utilities for trashed files and key encoding (classes.trash.ts).
+- Enhance Bucket operations: fastCopy now preserves or replaces native metadata correctly, cleanAllContents supports paginated deletion, and improved fastExists error handling (classes.bucket.ts).
+- Fix Directory.getSubDirectoryByName to construct new Directory instances with the correct parent directory reference.
+- Add tests covering metadata absence and pagination behavior (test/test.local.node+deno.ts).
+
+## 2025-11-20 - 4.0.1 - fix(plugins)
+Use explicit node: imports for native path and stream modules in ts/plugins.ts
+
+- Replaced imports of 'path' and 'stream' with 'node:path' and 'node:stream' in ts/plugins.ts.
+- Ensures correct ESM resolution of Node built-ins when package.json type is 'module' and avoids accidental conflicts with userland packages.
+
+## 2025-11-20 - 4.0.0 - BREAKING CHANGE(core)
+Make API strict-by-default: remove *Strict variants, throw on not-found/exists conflicts, add explicit exists() methods, update docs/tests and bump deps
+
+- Breaking: Core API methods are strict by default and now throw errors instead of returning null when targets are missing or already exist (e.g. getBucketByName, getFile, getSubDirectoryByName, fastPut, fastPutStream).
+- Removed *Strict variants: fastPutStrict, getBucketByNameStrict, getFileStrict, getSubDirectoryByNameStrict — use the base methods which are now strict.
+- Added explicit existence checks: bucketExists (SmartBucket), fileExists (Directory/fileExists), directoryExists (Directory.directoryExists), and fastExists (Bucket.fastExists) to allow non-throwing checks before operations.
+- Return type updates: fastPut now returns Promise<File> (no null), getBucketByName/getFile/getSubDirectoryByName now return the respective objects or throw.
+- Improved error messages to guide callers (e.g. suggest setting overwrite:true on fastPut when object exists).
+- Updated README, changelog and tests to reflect the new strict semantics and usage patterns.
+- Developer/runtime dependency bumps: @git.zone/tsbuild, @git.zone/tsrun, @git.zone/tstest, @aws-sdk/client-s3, @push.rocks/smartstring, @tsclass/tsclass (version bumps recorded in package.json).
+- Major version bump to 4.0.0 to reflect breaking API changes.
+
+## 2025-11-20 - 4.0.0 - BREAKING: Strict by default + exists methods
+Complete API overhaul: all methods throw by default, removed all *Strict variants, added dedicated exists methods
+
+**Breaking Changes:**
+
+**Putters (Write Operations):**
+- `fastPut`: Return type `Promise<File | null>` → `Promise<File>`, throws when file exists and overwrite is false
+- `fastPutStream`: Now throws when file exists and overwrite is false (previously returned silently)
+- `fastPutStrict`: **Removed** - use `fastPut` directly
+
+**Getters (Read Operations):**
+- `getBucketByName`: Return type `Promise<Bucket | null>` → `Promise<Bucket>`, throws when bucket not found
+- `getBucketByNameStrict`: **Removed** - use `getBucketByName` directly
+- `getFile`: Return type `Promise<File | null>` → `Promise<File>`, throws when file not found
+- `getFileStrict`: **Removed** - use `getFile` directly
+- `getSubDirectoryByName`: Return type `Promise<Directory | null>` → `Promise<Directory>`, throws when directory not found
+- `getSubDirectoryByNameStrict`: **Removed** - use `getSubDirectoryByName` directly
+
+**New Methods (Existence Checks):**
+- `bucket.fastExists({ path })` - ✅ Already existed
+- `directory.fileExists({ path })` - **NEW** - Check if file exists
+- `directory.directoryExists(name)` - **NEW** - Check if subdirectory exists
+- `smartBucket.bucketExists(name)` - **NEW** - Check if bucket exists
+
+**Benefits:**
+- ✅ **Simpler API**: Removed 4 redundant *Strict methods
+- ✅ **Type-safe**: No nullable returns - `Promise<T>` not `Promise<T | null>`
+- ✅ **Fail-fast**: Errors throw immediately with precise stack traces
+- ✅ **Consistent**: All methods behave the same way
+- ✅ **Explicit**: Use exists() to check, then get() to retrieve
+- ✅ **Better debugging**: Error location is always precise
+
+**Migration Guide:**
+
+```typescript
+// ============================================
+// Pattern 1: Check then Get (Recommended)
+// ============================================
+
+// Before (v3.x):
+const bucket = await smartBucket.getBucketByName('my-bucket');
+if (bucket) {
+  // use bucket
+}
+
+// After (v4.0):
+if (await smartBucket.bucketExists('my-bucket')) {
+  const bucket = await smartBucket.getBucketByName('my-bucket'); // guaranteed to exist
+  // use bucket
+}
+
+// ============================================
+// Pattern 2: Try/Catch
+// ============================================
+
+// Before (v3.x):
+const file = await directory.getFile({ path: 'file.txt' });
+if (!file) {
+  // Handle not found
+}
+
+// After (v4.0):
+try {
+  const file = await directory.getFile({ path: 'file.txt' });
+  // use file
+} catch (error) {
+  // Handle not found
+}
+
+// ============================================
+// Pattern 3: Remove *Strict calls
+// ============================================
+
+// Before (v3.x):
+const file = await directory.getFileStrict({ path: 'file.txt' });
+
+// After (v4.0):
+const file = await directory.getFile({ path: 'file.txt' }); // already strict
+
+// ============================================
+// Pattern 4: Write Operations
+// ============================================
+
+// Before (v3.x):
+const file = await bucket.fastPutStrict({ path: 'file.txt', contents: 'data' });
+
+// After (v4.0):
+const file = await bucket.fastPut({ path: 'file.txt', contents: 'data' }); // already strict
+```

+* The project uses the official s3 client, not the minio client.
+* **All methods throw by default** (strict mode):  - Put operations: `fastPut`, `fastPutStream` throw when file exists and overwrite is false  - Get operations: `getBucketByName`, `getFile`, `getSubDirectoryByName` throw when not found
+* **Use exists() methods to check before getting**: `bucketExists`, `fileExists`, `directoryExists`, `fastExists`
+* **No *Strict methods**: All removed (fastPutStrict, getBucketByNameStrict, getFileStrict, getSubDirectoryByNameStrict)
+* metadata is handled though the MetaData class. Important!
