# Расчет площади и периметра

This project can be used as a starting point to create your own Vaadin application with Spring Boot.
It contains all the necessary configuration and some placeholder files to get you started.

## Running the application

The project is a standard Maven project. To run it from the command line,
type `mvnw` (Windows), or `./mvnw` (Mac & Linux), then open
http://localhost:8080 in your browser.

You can also import the project to your IDE of choice as you would with any
Maven project. Read more on [how to import Vaadin projects to different IDEs](https://vaadin.com/docs/latest/guide/step-by-step/importing) (Eclipse, IntelliJ IDEA, NetBeans, and VS Code).

## Deploying to Production

To create a production build, call `mvnw clean package -Pproduction` (Windows),
or `./mvnw clean package -Pproduction` (Mac & Linux).
This will build a JAR file with all the dependencies and front-end resources,
ready to be deployed. The file can be found in the `target` folder after the build completes.

Once the JAR file is built, you can run it using
`java -jar target/lab3-1.0-SNAPSHOT.jar`

## Project structure
