The real-time community site Voten that recently made its first public beta has just announced it’s now an open source project. Voten is powered by Laravel 5.4 and Vue.js so it could be a good project to learn from the source, contribute, and get involved with.
Voten’s source code can be found on Github and they’ve also made the /c/votendev channel to discuss the development side.
They also have a /c/laravel and /c/vuejs channel if you’d like to submit some of your own work.
