How to set React app variables in NPM start script

so the npm start in my package.json looks like this

"start": "REACT_APP_Environment=development react-scripts start",

This worked fine for previous developers on the project, possibly because they were on MacOS, that's not the case for me on windows, when I run I get 

> REACT_APP_Environment=development react-scripts start

'REACT_APP_Environment' is not recognized as an internal or external command,
operable program or batch file.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] start: `REACT_APP_Environment=development react-scripts start`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the [email protected] start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\Omar\AppData\Roaming\npm-cache\_logs\2019-09-22T15_12_59_217Z-debug.log

I can fix this by removing the environment variable from the start script and running by the command set "REACT_APP_Environment=development" && npm start, but this is not convenient, how can I have it all included and work properly on windows in my start script? thanks

I would recommend checking out .env, seems like it might solve your problem

npmjs.com/package/dotenv
