v1.1.3 - Advanced Data Handling Improvements

[1.1.3] - 2025-04-27

Added

• JSON Schema Validation: New validateJsonSchema function to validate JSON objects against provided schemas using AJV.
• Batch Processing: New batchProcess function to divide and process large JSON arrays in batches asynchronously.
• Pretty-Print for XML: XML output now supports customizable pretty formatting through the prettyPrint option.
• Flatten Helpers: New modular helpers flattenObject and flattenJson to standardize object flattening across converters.
• Custom CSV Header Mapping: customCSVFieldGenerator added for precise header customization in toCSV.
• Automatic Flattening in toCSV: Nested JSON objects are automatically flattened in CSV output.
• Error Handling Improvements: Better error messages and stricter input validation across all main converters.
• Improved Test Coverage: Full unit test coverage for converters and internal helpers.

Changed

• Internal refactor: Splitted converters and helpers into modular architecture (@helpers, @converters, etc).
• Aliases introduced in tsconfig (@converters, @utils, @types) to improve import management and code clarity.
• Updated internal types for stronger validation (JsonArray, JsonObject, etc).

Fixed

• Correct flattening of deeply nested objects in CSV generation.
• Proper handling of empty objects across all converters (returning safe outputs).
• Small bug fixes and improvements for JSONLines stream generation.

Added

• Updated package.json to support both ESM and CJS using exports field and type: module.
• Updated Jest config to support ESM with --experimental-vm-modules.
• Adjusted tsconfig.json for compatibility with new build setup.
• Migrated build system to tsup for faster and modern bundling.
• Improved GitHub Actions workflow for release publishing.
• Refactored core imports to use import type syntax.

v1.1.1 Automated npm Publishing with GitHub Actions

[1.1.1] - 2025-01-10

Added

• Automation using GitHub Actions to automatically publish to npm when a new release is created.
• Validates package version to prevent publishing duplicate versions.
• Executes automated tests (npm test) to ensure package stability.
• Adds dependency caching to improve CI/CD performance.
• Configures npm authentication automatically via .npmrc.

v1.1.0 - New Features: YAML, JSONLines, and Stream Enhancements

[1.1.0] - 2025-01-09

Added

• JSON to YAML Conversion: Added support for converting JSON to YAML for configurations like Kubernetes and Ansible.
• JSON to JSONLines (NDJSON): Transform JSON arrays into JSONLines, ideal for incremental processing and data pipelines.
• JSONLines Stream: Generate readable streams of JSONLines to handle large volumes of data efficiently.

Fixed

• General improvements in input validation for existing functions.
• Memory optimizations for large conversions.

v1.0.2 - Minor Improvements and Enhanced Functionality

[1.0.2] - 2025-01-06

Added

• Custom header labels for CSV: Allows specifying friendly column names instead of using raw JSON keys.
• Nested object flattening in CSV: Transforms nested fields (e.g. details.age) into separate columns.
• Type-based CSV output: Numbers are unquoted, strings are quoted, and null/undefined fields are left empty.
• Large dataset test coverage: Ensures performance and correctness for bigger JSON arrays.

Fixed

• Incorrectly quoted numeric fields in CSV outputs.
• Inconsistent handling of empty or null fields when generating CSV.

v1.0.1 - Minor Improvements and Enhanced Functionality

[1.0.1] - 2025-01-04

• Enhanced Markdown table generation with dynamic header extraction.
• Better error handling for empty JSON arrays in toMarkdownTable and invalid inputs in toXML.
• New file structure: Organized modules into dedicated files for better maintainability and scalability.

Fixed

• Corrected edge cases in CSV output when handling missing keys.
