Open firewall for Expo node project (windows)

If you are testing your mobile app from a real devicc and need to access your expo app locally, here’s an example of opening the ports for the necessary services. (Windows powershell (admin))

# Allow Node.js inbound
New-NetFirewallRule -DisplayName "Node.js" -Direction Inbound -Program "C:\Program Files\nodejs\node.exe" -Action Allow

# Allow specific Expo port
New-NetFirewallRule -DisplayName "Expo Dev Server" -Direction Inbound -Protocol TCP -LocalPort 8081 -Action Allow

# Allow Metro bundler port range
New-NetFirewallRule -DisplayName "Metro Bundler" -Direction Inbound -Protocol TCP -LocalPort 19000-19006 -Action Allow

Expo eas build + ios + firebase pods error

Today I had some trouble rebuilding my IOS project via Expo’s eas while implementing Firebase SDK.


Solution for my case:
1.) install expo-build-properties

npx expo install expo-build-properties

2.) Add the “expo-build-properties” part in your app.json/app.config.js

    plugins: [
      "@react-native-firebase/app",
      "@react-native-firebase/messaging",
      [
        "expo-build-properties",
        {
          ios: {
            useFrameworks: "static",
            podfileProperties: {
              "use_modular_headers!": true,
            },
          },
        },
      ],
