I have a .env file:
REACT_APP_URL={value}
REACT_APP_API_URL={value}
REACT_APP_VEHICLE_IMAGE_URL={value}
REACT_APP_NAME={value}
REACT_APP_GA_TRACKING_ID={value}
REACT_APP_WEBSITE_URL={value}
That is my current file of eas.json:
{
"cli": {
"version": ">= 10.0.2"
},
"build": {
"development": {
"developmentClient": true,
"distribution": "internal",
"ios": {
"simulator": true
}
},
"preview": {
"distribution": "internal"
},
"production": {}
},
"submit": {
"production": {}
}
}
I have stored these values in eas secret by running the command:
eas secret:push --scope project --env-file .env
I have stored on env some secret but the problem is when I run the app the env values are not stored in the build
when i run eas build --platform android --non-interactive --no-wait
I get this:
Loaded "env" configuration for the "production" profile: no environment variables specified
How can i load the env from the eas secret I have added, so when i build i can run the application with those variables?

Expo environment variables
Actually, your .env file should contain the variables like the following:
EXPO_PUBLIC_API_URL=https://staging.example.com
EXPO_PUBLIC_API_KEY=abc123
And inside your codes, you can use the variables like the following:
import { Button } from 'react-native';
function Post() {
const apiUrl = process.env.EXPO_PUBLIC_API_URL;
async function onPress() {
await fetch(apiUrl, { ... })
}
return <Button onPress={onPress} title="Post" />;
}
For more information about using Expo environment variables you can read this link.
HINT: Use the exact phrase process.env.EXPO_PUBLIC_XXX to get the variable from the .env file. The _XXX is your custom name.
EAS Build
To have a correct EAS Build you should write the eas.json file like the following:
{
"build": {
"development": {
"env": {
"EXPO_PUBLIC_API_URL": "https://api.development.com"
}
},
"production": {
"env": {
"EXPO_PUBLIC_API_URL": "https://api.production.com"
}
},
"test": {
"env": {
"EXPO_PUBLIC_API_URL": "https://api.test.com"
}
}
}
}
