How to run two commands in an executable file in different folders?

Question

I'm trying to create an executable that runs two commands in two different folders.

I am developing using React application and Express API, they are located in two different folders. I tried creating a .bat file, running npm run dev in my API folder, and then opening a new terminal, in my application folder I run npm start but I can't get it to work.

It is important to open two terminals to keep both processes running.

My current code is as follows:

@echo off

rem changes directory and runs the command in the current command prompt
cd "path\one\"
echo run 'npm run dev' in the current command prompt
start cmd /c "npm run dev"

rem opens a new command prompt window, changes directory and runs the command
start cmd /k "cd path\two && echo Run 'npm start' && npm start"

in a new command prompt

After running it, it just says that the specified path cannot be found.

Any help would be greatly appreciated!

Thanks so much Mofi, I finally got it working!

This is the code I use:

The bug pointed out by Mofi has been fixed

@echo off

@start "npm start" /D"path1" %ComSpec% /D /C npm.cmd start
@start "npm start" /D"path2" %ComSpec% /D /K npm.cmd start

Thanks again! Now I have to figure out how to run npm i in both paths and run other commands after npm i is finished.
