Hi there 
I’ve been working on Sounds Social these past few weeks, which is a platform all about music and collaboration. There’s a lot of potential to share audio and wealth in ways that current platforms don’t take advantage of.
Meteor is used for the GraphQL API (backend only). Really enjoyed developing with the meteor apollo integration. GraphiQL makes testing and exploring the API a breeze. There’s a separate frontend Vue app to access the GraphQL endpoint with apollo-client.
Feel free to check out the repository on Github or check out the dev environment to see what’s already there. Maybe this app can give you a good insight into what’s possible with GraphQL and / or Meteor. Hope it’s helpful
