How to call localhost "https" server in React Native?-CodePudding

I'm trying to call "https" localhost server from Expo React Native app. But i'm getting "Network Error". How to call https server in React Native?

Initialise baseUrl in React Native => baseUrl = Platform.OS === "ios" ? "https://localhost:1999" : "https://10.0.2.2:1999"

If I understand your question correctly try typing

npm start

in your terminal. Then after that it will prompt you with a choice to either run it in an emulator or on web. all you have to do is hit 'w' on your keyboard. That should run it in your default browser.

 Starting Metro Bundler
› Metro waiting on [ip]
› Linking is disabled because the client scheme cannot be resolved.

› Press a │ open Android
› Press i │ open iOS simulator
› Press w │ open web

› Press r │ reload app
› Press m │ toggle menu
› Press d │ show developer tools
› shift d │ toggle auto opening developer tools on startup (disabled)

› Press ? │ show all commands

just hit 'w' after this console message

If you are developing your app in pc and trying to view app in mobile phone, you should not use "localhost" instead

connect to same LAN, hotspot

If on windows -

goto cmd
type "ipconfig"
goto ipv4 address it looks like ("192.168.178.43")
this is written instead of localhost in mobile
put : after it and write port number
your url will look like 192.168.178.43:1999

if on linux/mac - -go to bash/fish/zsh -type "ifconfig" -do the same as in linux
