Vaadin Login Project

WebApp deployed via Heroku at the following link: https://vaadin-login-page.herokuapp.com/

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.
Default credentials:

User: user
Password: userpass

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 (Eclipse, IntelliJ IDEA, NetBeans, and VS Code).

Database

Local

When running the project locally, an h2 in-memory database is used. Data can be view following this steps:

Open the application.properties file.
Write the following code:

spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=password
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.h2.console.enabled=true

Go to http://localhost:8080/h2-console/ and log in:

JDBC URL: jdbc:h2:mem:testdb
User: sa
Password: password
We'll leave the rest of the fields as they're.

On the cloud

When the app is running via the https://vaadin-login-page.herokuapp.com/ page, a PostgreSQL database is used instead. Data is stored using a database provided by Heroku, where the project is hosted.

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/flowcrmtutorial-1.0-SNAPSHOT.jar

Project structure

MainLayout.java in src/main/java contains the navigation setup (i.e., the side/top bar and the main menu). This setup uses App Layout.
views package in src/main/java contains the server-side Java views of your application.
views folder in frontend/ contains the client-side JavaScript views of your application.
themes folder in frontend/ contains the custom CSS styles.

User management

User's privileges aren't managed, it's just a demo and security is't the purpose of it. In case of looking to add or manage the existing users to log into the page, they can be modified following the next steps:

Go to the SecurityConfig.java file.
Default user is defined using the CrmMemoryUserDetailsManager constructor. See the following arrow.

private static class CrmMemoryUserDetailsManager extends InMemoryUserDetailsManager{
        public CrmMemoryUserDetailsManager(){
    ---->   createUser(new User("user","{noop}userpass", Collections.singleton(new SimpleGrantedAuthority("USER"))));
            //createUser(new User("admin","{noop}adminpass",Collections.singleton(new SimpleGrantedAuthority("ADMIN"))));
        }
    }

The line below the arrow shows what we would have to do if we wanted to add an admin user with admin privileges.

Final result
