🗣 Translations

You can help us with translate the app with our online tool POEditor. Any help is appreciate and no coding skills are needed 🤗

PS: please do not use send translations made by Google translate or similar.

Generate

Run node scripts/generate-translation-files.js in order to create the files needed for the new language you want to add to the app.

Manage Files

Run node scripts/poeditor/group-translation-files.js to generate 1 JSON file per language, with all the translation vars in it. From there, you can easily make any edit you want. When you're done, you can run node scripts/poeditor/spread-translation-files.js to merge your edits and spread them into all the translation files across the repo.

🚀 Deployment

Any tag starting with v will runs expo publish. During this step app.example.json is used to generate an app.json file for expo's deployment, this is done with the following script scripts/generate-app-json.js.

🏗 Build

First you need to configure SENTRY_AUTH_TOKEN and SENTRY_DSN secrets on expo.dev and then define projectId in app.config.js. Then run npm install dotenv and place your secrets inside .env file that you need to create with SENTRY_AUTH_TOKEN and SENTRY_DSN, like in .env.example.

Run eas build -p ios to build for the App Store Connect and eas build -p android for the Google Play Console.
