feat(core): Add `environment` option to Expo config plugin by antonis · Pull Request #5796 · getsentry/sentry-react-native

📢 Type of change

Bugfix
New feature
Enhancement
Refactoring

📜 Description

Adds environment configuration in the Expo config plugin. The environment can be set via:

The environment plugin prop in app.json:

["@sentry/react-native/expo", {
  "useNativeInit": true,
  "environment": "staging"
}]

The SENTRY_ENVIRONMENT environment variable (e.g. per EAS Build profile in eas.json):

{
  "build": {
    "production": { "env": { "SENTRY_ENVIRONMENT": "production" } },
    "staging": { "env": { "SENTRY_ENVIRONMENT": "staging" } }
  }
}

The plugin prop takes precedence over the env variable. The value is written into sentry.options.json during expo prebuild, so that native init (useNativeInit: true) tags pre-JS crashes with the correct environment.

💡 Motivation and Context

Closes #5779

There is currently no way to dynamically specify the environment field in sentry.options.json. Users building for multiple environments need different values, but the file is static. While Sentry.init() in JS can override environment, pre-JS crashes would still be tagged with the wrong environment.

💚 How did you test it?

Unit tests for writeSentryOptionsEnvironment covering:
- Creates sentry.options.json when file does not exist
- Overrides environment in existing file
- Adds environment to file that doesn't have it, preserving other options
All existing expo-plugin tests pass
ESLint passes
Build passes

📝 Checklist

I added tests to verify changes
No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled
I updated the docs if needed. See feat(react-native): Add environment option to Expo config plugin sentry-docs#16857
I updated the wizard if needed.
All tests passing
No breaking changes
