@live queries in graph-client

Graph-Client implements a custom @live directive that can make every GraphQL query work with real-time data.

Start by adding the following configuration to your .graphclientrc.yml file:

plugins:
  - pollingLive:
      defaultInterval: 1000

Set the default update interval you wish to use, and then you can apply the following GraphQL @directive over your GraphQL queries:

query ExampleQuery @live {
  transactions(first: 2, orderBy: timestamp, orderDirection: desc) {
    id
    blockNumber
    timestamp
  }
}

Or, you can specify a per-query interval:

query ExampleQuery @live(interval: 5000) {
  transactions(first: 2, orderBy: timestamp, orderDirection: desc) {
    id
  }
}

Since the entire network layer (along with the @live mechanism) is implemented inside graph-client core, you can use Live queries with every GraphQL client (such as Urql or Apollo-Client), as long as it supports streame responses (AsyncIterable).

No additional setup is required for GraphQL clients cache updates.
