Application is build with Quarkus.

It runs live on AWS Lambda, receives hooks from Telegram via API Gateway.

The Telegram Bot can be used here: @demo_tkach_weather_bot

You can view the online stream on YouTube after making a donation to support my volunteering initiative to help Ukrainian Armed Forces.

Thank you in advance for your support! Слава Україні! 🇺🇦

Before running the application you need to set the API KEY for geo coding service and a Telegram bot token to verify requests from Telegram.

You can do this by setting the values in application.yml file or with environment variables:

APP_GEO_CODE_API_KEY=your-api-key
APP_TELEGRAM_SECRET_TOKEN=your-bot-token

You can run your application in dev mode that enables live coding using:

./gradlew quarkusDev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

The application can be packaged using:

./gradlew build

It produces the quarkus-run.jar file in the build/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the build/quarkus-app/lib/ directory.

The application is now runnable using java -jar build/quarkus-app/quarkus-run.jar.

If you want to build an über-jar, execute the following command:

./gradlew build -Dquarkus.package.type=uber-jar

The application, packaged as an über-jar, is now runnable using java -jar build/*-runner.jar.

You can create a native executable using:

./gradlew build -Dquarkus.package.type=native

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

./gradlew build -Dquarkus.package.type=native -Dquarkus.native.container-build=true

You can then execute your native executable with: ./build/demo-3-en-telegram-weather-bot-1.0.0-SNAPSHOT-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/gradle-tooling.
