Room Signals​

A service with room and messages, an user can subscribe to a room to listen to messages and send private or group-wide messages. Useful for simple messages or setting up peer-to-peer protocols like WebRTC. The service uses web sockets and in the source code repository there are three projects:

  1. The Leto Shelf GraphQL server. Everything is saved in memory
  2. A Dart client using Artemis
  3. A Web Dart client using package:rad

You can view the code in the Github repo. The client UI and some links to the different GraphQL Schema UI explorer is deployed in this page.

CI & CD Dart Server​

Work in Progress

A service for compiling, executing and tracking the build process and deployment. With a git repository, one can set up a CLI pipeline for continuous integration and delivery. All the commands are tracked in realtime. This is a simple personal project for deploying in a VM. The service uses web sockets and the source code repository has three projects:

  1. The Leto Shelf GraphQL server. Everything is saved in memory
  2. A Dart client using package:graphql and package:graphql_codegen
  3. A Web Dart client using package:jaspr

You can view the code in the Github repo. The client UI and some links to the different GraphQL Schema UI explorer is deployed in this page.
