v3.0.0

🚀 Features & Compatibility

• TSL Linter Compatibility Layer: The TSL(https://github.com/ArnaudBarre/tsl) compatibility layer has been consolidated for efficient and unified handling of TypeScript linting rules.
• ESLint Integration: We've re-introduced @tsslint/compat-eslint as a separate package and updated the overall integration logic for interoperability with the existing ESLint ecosystem.
• TSLint Migration: The new importTSLintRules feature allows direct import of legacy TSLint rules into your configuration, simplifying the migration path from TSLint.

⚙️ Developer Experience & Efficiency

• Reduced Dependency Footprint (No esbuild):
  • Removed esbuild dependency for runtime operations.
  • Native .ts Import: We now leverage Node.js's native support to import .ts files, reducing build complexity and improving startup speed.
• Documentation Tooling:
  • tsslint-docgen Introduced: A new tool for automated rule documentation generation.
  • JSDoc Improvements: Based on tsslint-docgen, the JSDoc for defineRules has been updated, providing clearer API documentation for rule developers.
• CLI Caching:
  • Cleaner Projects: The CLI cache is now stored in the OS temporary directory, preventing cache files from polluting your project folders.
• Error Reporting: The core Reporter API has been updated to provide more accurate error location tracing (via Reporter.at and chainable methods), which aids rule development and debugging.
• Node.js Support: Compatibility with Node.js 22.6.0 and newer versions is confirmed.

⚠️ Breaking Changes & Migration Guide

• CLI Parameter Renaming:
  • Old: --projects
  • New: --project
  • Action Required: Update your CLI scripts to use the singular form --project.
• ESLint Plugin Renaming:
  • Old: createDisableNextLinePlugin
  • New: createIgnorePlugin
  • Action Required: Update your ESLint configurations to use createIgnorePlugin.
• Removal of --threads (Resource Efficiency Rationale):
  • Reasoning: Due to Node.js's memory-sharing limitations, multi-threading in TypeScript projects often leads to poor resource utilization. Benchmarks showed that multi-threading could consume 2x the energy for only a 1.5x speed increase (with performance degrading further with more threads).
  • Decision: As a project committed to system resource efficiency, we are deprecating this inefficient mode of operation.
  • Future Plan: We plan to introduce a more rational and resource-efficient multi-threading solution in a future release to provide performance gains for large projects without sacrificing system resources.
  • Action Required: Please update your automation scripts or CI/CD configurations.
• Core Refactoring: This release includes significant underlying refactoring and API adjustments. Please check the latest README to understand the latest API usage and configuration details.
• Deprecated Feature Removal: Support for the deprecated --projects CLI flag and the old disableNextLine ESLint plugin has been removed.
