About

SparkRadarWX is a free, open source, beautiful weather app for android, built with Expo and React Native and integrated with SparkRadar.

This project is still in BETA and may contain bugs.

Note: Staring in preview v0.1.10, SparkRadarWX now uses the backend at SparkRadarWXAPI OneCall

Download

• Get it with Obtainium: Add https://github.com/tgranz/SparkRadarWX as a source. Optionally, tick "include prereleases".
• Get it from the releases section on this page.

Instructions are for Linux/Ubuntu systems.

Test

1. Clone or download the source code.
2. Download the Expo Go app from the Play Store or App Store.
3. Install and setup EAS with sudo npm install -g eas-cli. Then run eas init. You will need an expo.dev account.
4. Install dependencies with npm install.
5. Add a .env file with ONECALL_API_KEY=<your_key>. This is the same API key you set up in the OneCall API .env file.
6. Start the development server with npx expo start.
7. In Expo Go, find the QR scanner and scan the QR code in the terminal. The app should compile and be running on your device.

Build (Android)

Follow "Test", then...

1. Configure your OneCall API key for the app with eas env:create --scope project --name ONECALL_API_KEY --value "your_key_here". For "visibility" choose "secret", and for "environment", choose "development", "preview", and "production". This is necessary since expo will not compile your .env file with the app.
2. Ensure your eas.json file looks something like this:

...
  "build": {
    "preview": {
      "distribution": "internal",
      "android": {
        "buildType": "apk" // Important
      }
    },
...

3. Run eas build --profile preview --platform android. (Build may take a while as it is built on the EAS server, not your local machine.)
4. If asked to create an EAS project, enter y.
5. If asked to generate an android keystore, enter y.
6. EAS will compile an apk file of the app. You can now install it to your device.

Will we see an iOS app?

No. I do not wish to pay $100 a year to put the app on the App Store. I also do not own an iPhone to perform native testing. If you are up to it, however, feel free to for the code and build an iOS version!
