TypeScript-Watcher

1. Build: To build all .ts sources and ouput .js files into a location, execute
   • tscwatch build <rootPath> <outputPath> [options]
2. Watch: To continuously watch .ts files for changes and output compiled .js, execute
   • tscwatch watch <rootPath> <outputPath> [options]
3. Load Config: To load an external config .json file, execute

• tscwatch run-config <path to config.json> [options]

TODO

• Write tests

Thanks

• Core TypeScript compilation code was extracted from Josh Heyse's typescript-brunch plugin: https://github.com/joshheyse/typescript-brunch
• Inspiration and various file-utilities came from Paul Miller's incredible application-assembler, Brunch: https://github.com/brunch
