PR Summary

• Javascript watching disabled in sample configuration
  The sample configuration file (less-watch-compiler.sample.config.json) was modified to no longer support monitoring changes in Javascript files.

• Main application entry point changed
  The principal entry point for this project, specified in package.json, has been changed from 'dist/less-watch-compiler.js' to the more standard 'dist/main.js'.

• Build process update
  The script that handles project building, referred to as build in package.json, has been updated. Previously, this script was using Babel, but it has been revised to now use Typescript.

• Files addition and deletion for better structure
  Certain non-essential JavaScript files were deleted, and their corresponding TypeScript files were created. These include src/lib/Options.ts, src/lib/Utils.ts, and several others. This was done to convert the existing JavaScript codebase to TypeScript.

• Enhanced file watching module
  New TypeScript files, like lessWatchCompilerUtils.cjs.js and lessWatchCompilerUtils.ts, were added to improve file watching capabilities. These components help keep track of changes in the project files and expedite necessary updates.

• Watchscript main script added
  A new TypeScript file src/main.ts was added. This script watches folders for changes and compiles LESS CSS files into CSS, thereby automatically reflecting styling changes made in LESS files without manual compilation.

• New tests added
  To ensure the integrity of the changes made in this PR, new test files like test/Utils.js and test/filesearch.js were added. These files include various test cases for the utility and file search modules, respectively.

• Configuration settings and CLI command updated
  Updates were made to test/less-watch-compiler.config.json and test/less-watch-compiler.js to modify the configuration settings for the less-watch-compiler and the command line interface (CLI).

• Updated module imports and test cases
  The test/lessWatchCompilerUtils.js file was modified to update the imports of lessWatchCompilerUtils and sh modules.

• Compiler configuration added
  A new file tsconfig.json was added, which specifies compiler options for the Typescript.
