Hub
Front end react state management. Grpc build in over websockets
import { createClient } from '@saulx/hub'
const client = createClient()
const fn = () => {
console.log('fire!')
}
// subscribe
client.rpc(
{
endpoint: 'f',
method: 'subscribe',
args: { uuid: 'firstname' }
},
fn
)
client.close(
{
endpoint: 'f',
method: 'subscribe',
args: { uuid: 'firstname' }
},
fn
)
// one off
const result = await client.rpc('f.subscribe', { hello: true })
Use it with react
import { useRpc, useHub, Provider, createClient } from '@saulx/hub'
const client = createClient()
const Something = () => {
// gives access to the hub context
const hub = useHub()
// handles unsubscribe / subscribe internally
const myValue = useRpc('f.subscribe')
// local values are on endpoint device
const localValue = useRpc('device.value')
return <div
onClick={() => hub.set('device.value', Math.floor(Math.random() * 99))}
>{myValue} {localValue}</div>
}
const App = () => {
return (
<Provider hub={client}>
<Something />
</Provider>
)
}
