I'd like to be able to launch my client-side React app from another programming language and pass it some command line arguments which would be passed to top level props or a context (or whatever).
I basically want to be able to launch a command like:
npm start inputFile="/path/to/input/file.ext"
And have the inputFile path be passed to my React app. Is this possible? I'm using create-react-app to bootstrap my app.
declare them before the command,
INPUT_FILE="/path/to/input/file.ext" ANOTHER_INPUT_FILE="/another/path/to/input/file.ext" npm start
accessible via process.env.INPUT_FILE
oh the convention is usually uppercase and separated by underscore between words.
or more convenient if you can just put them in .env file
