 # Changelog
 
+## 2025-12-13 - 3.1.3 - fix(npmextra)
+Align npmextra.json package name with package.json (@git.zone/tsbuild)
+
+- Corrected npmPackagename in npmextra.json from "@gitzone/tsbuild" to "@git.zone/tsbuild" to match package.json and README
+- Metadata-only change: no code or API behavior affected
+
+## 2025-11-28 - 3.1.2 - fix(TsBuild)
+Set default TypeScript target to ESNext
+
+- Default compiler target changed from ScriptTarget.ES2024 to ScriptTarget.ESNext in ts/tsbuild.classes.tsbuild.ts
+- Aligns the default compiler options with documentation and ensures use of the latest language features
+
+## 2025-11-27 - 3.1.1 - fix(compiler)
+Update default TypeScript target to ES2024
+
+- Default compiler option 'target' changed from ScriptTarget.ESNext to ScriptTarget.ES2024 in ts/tsbuild.classes.tsbuild.ts
+- Aligns emitted code to ES2024 language features by default
+
+## 2025-11-17 - 3.1.0 - feat(tsbuild.classes)
+Update default TypeScript lib to lib.esnext.d.ts
+
+- Changed default compilerOptions.lib from ['lib.dom.d.ts', 'lib.es2022.d.ts'] to ['lib.dom.d.ts', 'lib.esnext.d.ts'] in compilerOptionsDefault.
+- Allows newer ECMAScript/DOM features by default when compiling with tsbuild (affects emitted types and available globals).
+- Behavioral default change only — no public API changes; callers can still override lib via tsconfig, programmatic options, or CLI.
+
+## 2025-11-17 - 3.0.0 - BREAKING CHANGE(TsBuild)
+Stop forcing emitDecoratorMetadata in protected compiler defaults
+
+- Removed emitDecoratorMetadata from the set of protected/critical default compiler options.
+- Projects that relied on tsbuild automatically enabling emitDecoratorMetadata (for DI frameworks like NestJS, TypeORM, Inversify) must now enable it explicitly in their tsconfig.json or via programmatic/CLI options.
+- No other protected defaults were changed; outDir, noEmitOnError, declaration and inlineSourceMap remain enforced.
+- Behavior is now more permissive: decorator metadata generation is controlled by user configuration rather than being forced by tsbuild.
+
+## 2025-11-17 - 2.7.3 - fix(tsbuild.classes)
+Remove duplicate emitDecoratorMetadata from default compiler options and centralize it in protected defaults
+
+- Removed emitDecoratorMetadata from compilerOptionsDefault in ts/tsbuild.classes.tsbuild.ts to avoid duplicate configuration.
+- emitDecoratorMetadata remains enforced via getCriticalDefaults(), ensuring decorator metadata support is protected from tsconfig.json overrides.
+- Prevents inconsistencies during compiler option merging by centralizing the decorator-related setting.
+
+## 2025-11-17 - 2.7.2 - fix(compilerOptions)
+Remove experimentalDecorators and useDefineForClassFields from default TypeScript compiler options
+
+- Removed experimentalDecorators from compilerOptionsDefault in ts/tsbuild.classes.tsbuild.ts
+- Removed useDefineForClassFields from compilerOptionsDefault in ts/tsbuild.classes.tsbuild.ts
+- Default compiler options now rely on TypeScript's upstream defaults for decorator and class field behavior
+- If your project relies on these settings, re-enable them in your tsconfig.json or pass them via the programmatic API / CLI
+
+## 2025-11-02 - 2.7.1 - fix(readme)
+Update documentation: expand README with usage, CLI and API examples; add readme.hints.md project memory
+
+- Add readme.hints.md: new project memory / quick reference with public API and CLI summaries
+- Expand and restructure readme.md: more comprehensive Quick Start, CLI Commands, API Reference, configuration, examples and troubleshooting
+- Clarify protected compiler options, default compiler options, path transformation behavior and error-handling patterns
+- Docs-only change — no source code or behavioral changes
+
+## 2025-11-02 - 2.7.0 - feat(tsbuild)
+Add tsconfig.json support and safer compiler option merging; protect critical options; apply path and enum transforms; bump dependencies.
+
+- Add robust tsconfig.json reading with graceful fallback when no tsconfig is present or it is invalid
+- Merge compiler options in a clear priority order (defaults -> tsconfig -> protected defaults -> programmatic -> CLI flags)
+- Introduce protected (critical) compiler options that cannot be overridden by tsconfig.json: outDir, noEmitOnError, declaration, emitDecoratorMetadata, inlineSourceMap
+- Convert string values from tsconfig (target, module, moduleResolution) to TypeScript enum values where applicable; special-case NodeNext
+- Transform tsconfig path mappings by replacing './ts_' with './dist_ts_' to keep runtime path resolution consistent with compiled output
+- Expose getCriticalDefaults helper and adjust mergeCompilerOptions to apply protected defaults before programmatic and CLI overrides
+- Update README with documentation for tsconfig support, merge order, protected compiler options, and example tsconfig
+- Bump dependencies/devDependencies: @push.rocks/smartcli ^4.0.19, @push.rocks/smartlog ^3.1.10, typescript 5.9.3, @git.zone/tsrun ^1.6.2, @git.zone/tstest ^2.7.0
+
+## 2025-08-29 - 2.6.8 - fix(tsbuild)
+Avoid process.exit in library, add confirmskiplibcheck flag, improve CLI exit handling and JSON/quiet modes, update test script
+
+- Changed package.json test script from "tsrun test/test.ts --verbose" to "tstest test/test.ts --verbose".
+- Library no longer calls process.exit from compile and compileWithErrorTracking; errors are returned or thrown so callers can decide process termination.
+- skipLibCheck behavior updated: delay/warning only happens when --confirmskiplibcheck is present; otherwise a short informational note is printed (suppressed in --quiet/--json).
+- CLI now awaits compileGlobStringObject calls and inspects a final error summary attached to argv to decide process.exit(1) when errors occurred.
+- compileGlobStringObject/exports now respect --quiet and --json modes, emit a JSON summary when --json is used, and attach the final error summary to argv so the CLI can determine exit behavior.
+
+## 2025-08-18 - 2.6.7 - fix(tspublish)
+Bump @git.zone/tspublish dependency to ^1.10.3
+
+- Updated dependency @git.zone/tspublish from ^1.10.2 to ^1.10.3 in package.json
+
+## 2025-08-18 - 2.6.6 - fix(dependencies)
+Update dependency @git.zone/tspublish to ^1.10.2
+
+- Bumped @git.zone/tspublish in package.json from ^1.10.1 to ^1.10.2
+
+## 2025-08-18 - 2.6.5 - fix(dependencies)
+Bump dependencies and add pnpm-workspace configuration
+
+- Updated @git.zone/tspublish from ^1.9.1 to ^1.10.1
+- Updated @push.rocks/smartfile from ^11.2.4 to ^11.2.7
+- Updated @push.rocks/smartpath from ^5.0.18 to ^6.0.0
+- Updated typescript from 5.8.3 to 5.9.2
+- Updated devDependency @git.zone/tstest from ^1.10.1 to ^2.3.4
+- Added pnpm-workspace.yaml with onlyBuiltDependencies list (esbuild, mongodb-memory-server, puppeteer)
+
+## 2025-05-24 - 2.6.4 - fix(dependencies)
+Add .npmrc and update dependency versions for smartfile and tstest
+
+- Add .npmrc with registry configuration for npm
+- Bump @push.rocks/smartfile version from ^11.2.3 to ^11.2.4
+- Bump @git.zone/tstest version from ^1.9.0 to ^1.10.1
+
+## 2025-05-21 - 2.6.3 - fix(tsbuild)
+minor maintenance updates and documentation improvements
+
+- Updated commit metadata to align with project version
+- Refined CLI command parsing and diagnostics logging for better clarity
+- Improved code readability in compiler options merging
+
+## 2025-05-21 - 2.6.2 - fix(npm configuration)
+Remove .npmrc file to default npm registry behavior
+
+- Deleted .npmrc file that hard-coded the npm registry URL to https://registry.npmjs.org/
+- This change leverages npm's default registry settings and reduces configuration clutter
+
 ## 2025-05-21 - 2.6.1 - fix(tsbuild.classes)
 Improve error diagnostics handling by removing legacy helper and integrating more robust error summaries in the compilation process

+# @git.zone/tsbuild - Project Memory
+
+## Quick Reference
+
+### Public API (8 functions + 1 class)
+1. **compileFileArray()** - Basic compilation, throws on error
+2. **compileFileArrayWithErrorTracking()** - RECOMMENDED, returns IErrorSummary
+3. **compileGlobStringObject()** - Most powerful, multiple patterns
+4. **TsBuild Class** - Object-oriented API with compile, checkTypes, checkEmit methods
+5. **mergeCompilerOptions()** - Utility for option merging
+6. **compiler()** - Legacy function
+7. **emitCheck()** - Validate emit capability
+8. **checkTypes()** - Type checking only
+
+### CLI Commands (5)
+1. **tsbuild** (default) - Compiles ./ts/**/*.ts → ./dist_ts/
+2. **tsbuild custom <dir1> <dir2>** - Custom directory compilation
+3. **tsbuild tsfolders** - Auto-discover ts_* folders, compile in order
+4. **tsbuild emitcheck <pattern>** - Validate emit without output
+5. **tsbuild check [pattern]** - Type check only
+
+### CLI Flags
+- `--skiplibcheck` - Skip .d.ts type checking (shows warning)
+- `--confirmskiplibcheck` - Extended warning with 5s pause
+- `--disallowimplicitany` - Stricter type checking
+- `--commonjs` - Use CommonJS instead of ESNext
+- `--quiet` - Suppress non-error output
+- `--json` - JSON output format
+
+## Key Architecture Decisions
+
+### Configuration Priority (5 levels)
+1. Default options (hardcoded)
+2. tsconfig.json (if exists)
+3. Protected defaults (ensure integrity)
+4. Programmatic options (function params)
+5. CLI flags (highest priority)
+
+### Protected Options
+Cannot be overridden by tsconfig.json alone:
+- `outDir: 'dist_ts/'` - Path transformation logic
+- `noEmitOnError: true` - Build integrity
+- `declaration: true` - Library support
+- `emitDecoratorMetadata: true` - DI frameworks
+- `inlineSourceMap: true` - Debugging
+
+### Path Transformation
+- Automatic: `./ts_interfaces` → `./dist_ts_interfaces`
+- In tsconfig paths: `./ts_*` → `./dist_ts_*` (first array element only)
+
+## Default Compiler Options
+- Module: NodeNext (ESM with CommonJS fallback)
+- Target: ESNext (latest JavaScript)
+- Decorators: ENABLED (experimentalDecorators + emitDecoratorMetadata)
+- Source Maps: Inline (no separate .map files)
+- Declaration Files: ALWAYS generated (protected)
+- Output: dist_ts/
+- Implicit any: ALLOWED by default
+- esModuleInterop: true
+
+## Error Handling
+
+### Error Summary Structure
+```typescript
+interface IErrorSummary {
+  errorsByFile: Record<string, Diagnostic[]>
+  generalErrors: Diagnostic[]
+  totalErrors: number
+  totalFiles: number
+}
+```
+
+### Three Error Patterns
+1. **Throw Pattern** - compileFileArray: throws on error
+2. **Tracking Pattern** - compileFileArrayWithErrorTracking: returns IErrorSummary, NO throw
+3. **Boolean Pattern** - checkTypes/emitCheck: returns boolean
+
+RECOMMENDATION: Use compileFileArrayWithErrorTracking for production code
+
+## JSON Output Format
+```json
+{
+  "success": boolean,
+  "totals": {
+    "errors": number,
+    "filesWithErrors": number,
+    "tasks": number
+  },
+  "errorsByFile": {
+    "fileName": [
+      { "code": number, "message": string }
+    ]
+  }
+}
+```
+
+## Special Behaviors
+
+### tsfolders Command Ordering
+1. Always: ts_interfaces first
+2. Always: ts_shared second
+3. Then: Other folders by `order` property in their tspublish.json
+4. Finally: Folders without order property (Infinity)
+
+### check Command Default (No Arguments)
+Two-phase check:
+1. Phase 1: Type check ts/**/* (strict, include .d.ts)
+2. Phase 2: Type check test/**/* (relaxed, skipLibCheck: true)
+
+### Glob Pattern Support
+- `*` single level
+- `**` recursive
+- `?` single char
+- `{a,b}` alternation
+- Duplicates: Files matching multiple patterns compile multiple times
+
+### Task Information Display
+When compiling multiple files with taskInfo param:
+Shows: `[1/3] Compiling 45 files from ./src/**/*.ts`
+Plus: File counts, duration, and file type breakdown
+
+## File Structure
+- **index.ts** - Main entry, re-exports all
+- **tsbuild.exports.ts** - Core API functions
+- **tsbuild.classes.tsbuild.ts** - TsBuild class + utility functions
+- **tsbuild.cli.ts** - CLI command definitions
+- **plugins.ts** - Dependency imports (smartfile, smartpath, smartcli, etc.)
+- **paths.ts** - Path utilities (cwd, packageDir)
+
+## Dependencies Used
+- @git.zone/tspublish@^1.10.3 - Module ordering
+- @push.rocks/smartcli@^4.0.19 - CLI framework
+- @push.rocks/smartfile@^13.1.2 - File content handling (SmartFile, StreamFile, VirtualDirectory)
+- @push.rocks/smartfs@^1.2.0 - Filesystem operations (file listing, directory listing, etc.)
+- @push.rocks/smartpath@^6.0.0 - Path transformation utilities
+- @push.rocks/smartpromise@^4.2.3 - Promise utilities
+- @push.rocks/smartdelay@^3.0.5 - Delay utilities
+- typescript@5.9.3 - TypeScript compiler
+
+### smartfs Migration Notes
+- smartfile v13+ split filesystem operations to a separate @push.rocks/smartfs package
+- File listing uses smartfs fluent API: `smartfs.directory(path).recursive().filter(pattern).list()`
+- File existence checks use: `smartfs.file(path).exists()`
+- The `listFilesWithGlob()` helper in plugins.ts handles glob pattern parsing for smartfs
+
+## Edge Cases
+
+1. **Empty file list** - Returns [], no error
+2. **Glob duplicates** - Files compile multiple times, possible duplicate errors
+3. **Non-existent files** - Handled by TypeScript "file not found" errors
+4. **skipLibCheck warning** - 1-line default, 5-second pause with --confirmskiplibcheck
+5. **Missing tsconfig.json** - Graceful fallback, no error
+6. **Module resolution** - --commonjs switches to NodeJs (not NodeNext)
+7. **Source maps** - Inline only (not separate .map files)
+8. **File filtering** - Only .ts and .tsx; .d.ts and .js ignored
+
+## Build Safety Features
+- `noEmitOnError: true` - Prevents broken builds
+- Error aggregation before final output
+- Protected options ensure integrity
+- Pre-emit checks before emit phase
+- CLI exit code handling (0=success, 1=error)
+
+## Recent Changes (from git log)
+- 3.1.3 - Current version
+- Migrated filesystem operations from smartfile to smartfs
+- Updated @git.zone/tsrun to ^2.0.1
+- Updated @git.zone/tstest to ^3.1.3
+- Updated @push.rocks/smartfile to ^13.1.2
+- Added @push.rocks/smartfs@^1.2.0 for filesystem operations
+- Updated @types/node to ^25.0.1
+
+## Configuration Example (tsconfig.json)
+Paths get automatically transformed:
+```json
+{
+  "compilerOptions": {
+    "paths": {
+      "@utils/*": ["./ts_utils/*"]  // → ["./dist_ts_utils/*"]
+    }
+  }
+}
+```
+
+## No ts_* folders found in project root
+The project itself doesn't have ts_interfaces, ts_shared, etc. directories.
+The tsfolders command is designed for OTHER projects using tsbuild.
