## Product Overview

### Product Description

One of the main goals of status is to grow its community, however is not easy to work on status-go project as a community developer.
Is not easy to set up an environment

- Identify where to start
- Interact with status messaging system.
- Test your changes

The idea behind this swarm is to simplify this by allowing community developers to interact with status, based uniquely on status-go library.

### Requirements & Dependencies

- *Easy to use SDK* : Using a sdk should be as easy as using any other messaging system, allowing you to subscribe or publish to specific chats.
- *The less dependencies the better* : ATM and in order to interact with status messaging system we need to interact with code on status-go and status-react repos. This should be simplified to allow devs work only on top of status-go
- *Quick dev environment setup* : Following the previous point, if we’re only based on status-go, dev environment should be trivial. Should be easy to build apps and distribute them as binaries for different platforms.


### Minimum Viable Product

MVP should allow a developer to accomplish some minimal actions:

- Connect : creates a new connection
- Close : closes active connection
- Auth : login as a specific user
- Subscribe : subscribe to a channel
- Unsubscribe : unsubscribe from a channel
- Publish : send a message.

_All methods should work for 1to1, groups and public chats._

With this methods building a simple `autoresponder bot` should be as simple as:

**TO BE DEFINED**
```
// Connect to the default status url and defer closing the connection
st, _ := status.Connect(st.DefaultAddr) // -> localhost:51515
defer st.Close()

// Authenticate as an specific user
st, _ = status.Auth([]byte(“S3cretT0ken”))

// Subscribes to any message on chat chatID
sub, _ := st.Subscribe("chatID", func(m *st.Msg) {
    // Replies the received message
    m.Reply([]byte("I can help!”))
    sub.Unsubscribe()
})

// Simple message publisher
st.Publish(“buddy_token", []byte("Hello World"))

```

SDK should be provided with different, easy to follow and well documented examples _(TBD)_:

- Autoresponder bot (nice for testing)
- Google assistant integration
- Slack proxy (use status from slack)
- Reminders (set and get reminders)
