@live
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.
