We are involved in many open source and open data activities, as we want to support the community. These are projects that we use every day or used to rely on.
With tapir you can describe HTTP API endpoints as immutable Scala values. Each endpoint can contain a number of input parameters, error-output parameters, and normal-output parameters. Generate a tapir project here.

A free, open-source, MVC framework for creating elegant, modern Java web applications. Favors convention over configuration, is extensible using a plugin architecture, and ships with plugins to support REST, AJAX and JSON.
The Akka Persistence Postgres plugin allows for using PostgreSQL 11 and Amazon Aurora databases as a backend for Akka Persistence and Akka Persistence Query. It’s been originally created as a fork of the Akka Persistence JDBC plugin, focused on PostgreSQL features such as partitions, arrays, BRIN indexes, and others. The main goal is to keep index size and memory consumption at a moderate level while being able to cope with an increasing data volume.
The library provides two hooks that aim to facilitate working with asynchronous data in React by helping you the state of a `Promise` without redundant boilerplate by using the `PromiseResultShape` object.

Simplify your work with Hyperledger Fabric using our latest open source - Fablo. Fablo allows you to start a blockchain network on Docker with a single command. It supports RAFT and solo consensus protocols, multiple organizations and channels, chaincode installation and upgrade.
The Envers module aims to enable easy auditing/versioning of persistent classes. All that you have to do is annotate your persistent class or some of its properties, that you want to audit, with @Audited. For each audited entity, a table will be created, which will hold the history of changes made to the entity. You can then retrieve and query historical data without much effort.
akka-http is an Akka module, originating from spray.io, for building reactive REST services with an elegant DSL. akka-http is a great toolkit for building backends for single-page or mobile applications. In almost all apps there is a need to maintain user sessions, make sure session data is secure and cannot be tampered with. akka-http-session provides directives for client-side session management in web and mobile applications, using cookies or custom headers + local storage, with optional Json Web Tokens format support.
A simple application scaffolding project to allow quick start of development for modern, web based applications. If you'd like to have a jump start developing a Scala-based Single Page Application project, skipping the boring parts and focusing on the real business value, this template might be for you! Bootzooka contains only the very basic features, that almost any application needs (listed below). These features are fully implemented both on server- and client- side. We hope that the implementations can also serve as blueprints for new functionalities.
