yourendolife

This the research project wich goal was to try Vaadin. The idea was to create a web application with minimal possible use of regular front end technologies. In the end, the app does not contain a single line of HTML, does contain two javascript files (because I used one third party library - not required at all, but use of raw JavaScript code in Vaadin app is really easy) and one SCSS file.

The application itself connects to Endomondo services using Endo2Java to retrieve workouts information and does some processing using the data. Unless the domain has expired, application is available here: yourendolife.com.

The application uses Spring Boot. It integrates with Vaadin using Vaadin4Spring (at the time I was starting this project, there was no official Vaadin integration with Spring, now there is one).

Bunch of Vaadin add-ons have been used:

• PagedTable - pagination features for built-in tables
• GoogleMaps Add-On - integration with Google Maps with no javascript
• LazyLoadWrapper - to show nice spinner on pages that take more time to load
• JFreeChartWrapper - wrapper for easy use of JFreeChart charts
• TableExport - export tables to Excel
• LoginForm - auto-complete support in login form

App is doing reverse geolocation using MapQuest Nominatim API. To improve its performance, results are being cached in Mongo using geospatial indexes.
