Introducing: Expo Run Commands
May 28, 2021 - The run commands integrate with dev client to provide an experience that is very similar to Expo Go: when you run a debug build of a project with dev client installed, Expo CLI will launch directly into the project within the client, and it will also make it available under the “Recently in development” section of the app for easy access from other devices already running the client.

r/expo on Reddit: How to run expo with server at same time in one script
November 19, 2022 -
I am trying to run my express server and my expo app within the same script in my package.json.
I am not able to get it to work with concurrently:
"dev:with-server": "concurrently 'DEV_ENV=development npx expo start -c' 'cd server && npm run dev'"
or npm-run-all
"server": "npm run dev", "expo-dev": "DEV_ENV=development npx expo start -c", "dev:with-server": "npm-run-all --parallel server expo-dev",
neither of these are working. both are failing with the same error:
error An unexpected error occurred: "Cannot create property 'https' on string 'https://registry.yarnpkg.com'".
not sure what I am doing wrong here. anyone know? using expo 48

i think i solved it? they can run at the same time, but i think theres an issue when both of them are trying to be started EXACTLY at the same time. So I made a command to run concurrently with one, wait a few seconds to run other command. "dev:with-server": "concurrently 'cd server && npm run dev' 'node -e \"setTimeout(() => process.exit(0), 5000)\" && DEV_ENV=development npx expo start -c'",

Try a small bash script that runs npx expo start -c & cd server npm run dev & You can later add on behavior like prefixing all the output from Expo with [expo] and output from express with [web] with ANSI color-coding. However be aware that by interleaving stdout from two processes, output like the QR code from Expo might have express output spliced in the middle of it.

Before this change, there was no way to run commands like expo run <platform> -d "/path/to/my_app". The args parsing rightfully assumed the path to be the device name. Using --allows to run commands like that.
