@live queries in graph-client

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

Getting Started

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

1plugins:2  - pollingLive:3      defaultInterval: 1000

Usage

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

1query ExampleQuery @live {2  transactions(first: 2, orderBy: timestamp, orderDirection: desc) {3    id4    blockNumber5    timestamp6  }7}

Or, you can specify a per-query interval:

1query ExampleQuery @live(interval: 5000) {2  transactions(first: 2, orderBy: timestamp, orderDirection: desc) {3    id4  }5}

Integrations

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.
