There are multiple ways to create web applications with Frege.

• bare-bones Java Servlet support
• creating REST services with sparkjava plus DB access and view technology options
• full-stack webapps through Grails integration

Fregelet makes the Servlet API accessible from Frege.

Marimuthu has written a blog post on how to do this.

This approach is also used in the online repl and the respective code can be found here.

The Frege-Spark integration is available here consisting of chinook for the REST access, sirocco for database access, and diablo for html templating.

A full stack approach with views in Angular is provided by rayokota.

The Grails plugin is used here in order to implement a Frege tic-tac-toe game.
