// Файл "tsconfig.json": | |
// - устанавливает корневой каталог проекта TypeScript; | |
// - выполняет настройку параметров компиляции; | |
// - устанавливает файлы проекта. | |
// Присутствие файла "tsconfig.json" в папке указывает TypeScript, что это корневая папка проекта. | |
// Внутри "tsconfig.json" указываются настройки компилятора TypeScript и корневые файлы проекта. | |
// Программа компилятора "tsc" ищет файл "tsconfig.json" сначала в папке, где она расположена, затем поднимается выше и ищет в родительских папках согласно их вложенности друг в друга. | |
// Команда "tsc --project C:\path\to\my\project\folder" берет файл "tsconfig.json" из папки, расположенной по данному пути. | |
// Файл "tsconfig.json" может быть полностью пустым, тогда компилятор скомпилирует все файлы с настройками заданными по умолчанию. | |
// Опции компилятора, перечисленные в командной строке перезаписывают собой опции, заданные в файле "tsconfig.json". |
