Create a client SDK

[goloroden]

What is this feature about?

First, we should discuss whether we want to have a client SDK, given that we now have a GraphQL endpoint. However, we probably want to have one at least for the file API. If we do that, we might also want to have a general client SDK.

What needs to be done to implement this feature?

• [ ] Discuss what should be part of the client SDK
  • [ ] Accessing the File API
  • [ ] Sending command, subscribing to events, and running queries
• [ ] Create an SDK
• [ ] Add tests
• [ ] Decide how to build it (is it part of the official npm package, or is it a separate npm package?)
• [ ] Publish it
