1-я попытка пакетного файла — проблемы с асинхронными командами

Обходной путь для этой проблемы заключался в том, чтобы разбить исходный один скрипт на 2 скрипта, которые можно запускать в командной строке. Этот сплит необходимо было продолжить после того, как npm run build финиширует, и если composer vendor-expose нужно запустить и закончить. Это потому, что мой сценарий автоматически закрывается, когда они заканчиваются. Ниже приведены два скрипта с аргументами:

updateReactInSS_1 "C:\wamp64\www\silverstripeProject" "C:\wamp64\www\silverstripeProject\app\ReactApp"

Rem =======updateReactInSS_1=============
Rem updateReactInSS_1 is part 1 of 2 that updates a React Application nested inside a SilverStripe project.
Rem It deletes an existing React application build directory and rebuilds it with npm.
Rem Dependencies are node package manager (npm) and Composer installed globally by editing the
Rem environment variable path on your machine so they can be run from the command line (cmd).
Rem You also need a virtual host configured to point at your-SilverStripe-project folder.
Rem Argument 1 = full path to the nested SilverStripe project folder
Rem Argument 2 = full path to the nested React application
Rem updateReactInSS_1 file is located at Argument 2.
Rem updateReactInSS_2 file is located at Argument 2. It renames the "hash" js and css build files to "bundle"
Rem then copies and moves existing media build media files to the public directory of the SilverStripe project.
Rem Note: If "composer vendor-expose" runs then updateReactInSS_2 needs to be run again to complete the script.
Rem =======START===========
@echo off
Rem Checking argument 1 entered correctly.
if "%~1"= = "" (
echo You forgot to specify the full path to the SilverStripe project folder:
echo argument 1 = ?
goto exit
) else (
echo argument 1 = %1 (path to the SilverStripe project folder)
)
Rem Checking argument 2 entered correctly.
if "%~2"= = "" (
echo You forgot to specify the full path to the nested React application:
echo argument 2 = ?
goto exit
) else (
echo argument 2 = %2 (path to the nested React application)
)
Rem Going to React application path (NOTE could also add condition to check npm install if 1st time run)
cd %2
Rem Deletes the React application build directory if it exists and then use node package manager to build the React application.
if exist build\ del build /s /e
npm run build
:exit

updateReactInSS_2 "C:\wamp64\www\silverstripeProject" "C:\wamp64\www\silverstripeProject\app\ReactApp"

Rem updateReactInSS_2 is part 2 of 2.
Rem Argument 1 = full path to the nested SilverStripe project folder
Rem Argument 2 = full path to the nested React application
Rem updateReactInSS_2 file is located at Argument 2 (where updateReactInSS_1 is forced to end by npm run build).
Rem It renames the "hash" js and css build files to "bundle" and copies and moves
Rem existing build media files to the public directory of the SilverStripe project.
Rem Note: If updateReactInSS_2 is forced to end by composer vendor-expose command at Argument 1,
Rem you need to cd to Argument 2 to run updateReactInSS_2 again to complete the script. 
Rem If symlinks have already been created by Composer, the command composer vendor-expose is
Rem skipped so updateReactInSS_2 only needs to be run once from the command line. 
Rem =======START=======

Rem Rename main.hashcode.js to main.bundle.js so consistent with requirements in related SS page controller.
cd %2\build\static\js
rename main.*.js "main.bundle.js"
Rem Rename main.hashcode.css to main.bundle.css so consistent with requirements in related SS page controller.
cd %2\build\static\css
rename main.*.css "main.bundle.css"
Rem checking if composer vendor-expose needs to run to create symlinking.

Rem Copying media build files if media directory exists in React build files to the public folder in SilverStripe. project.
if exist %2\build\static\media\ (

goto exit

Пожалуйста, прокомментируйте с лучшими дизайнерскими решениями. Можно ли их объединить в один скрипт или управлять третьим скриптом, чтобы в командную строку нужно было вводить только одну команду? Я учусь и должен делать вещи, противоречащие передовой практике и правилам здесь!!!!! Большое спасибо, что уделили время и поделились своими знаниями на StackOverflow :-).
