@parity/mobx
Create one MobX store per JSON-RPC method.
Usage
@parity/mobx
creates one MobX store per RPC method, with an observable value updating whenever the underlying pubsub RPC fires.
For example, let's take syncing state. Instead of making a pubsub directly to api.pubsub.eth.syncing((error, result) => ...)
to detect whether we're currently syncing or not, we just spawn a MobX store, and observe the changes.
import stores from '@parity/mobx'
@observer
class MyComponent extends React.Component {
this.syncingStore = stores.eth.syncing().get(api); // Pass the api object to the store
render() {
const { syncing } = this.syncingStore
return <div>The syncing state is: {JSON.stringify(syncing)}</div>
}
}
And the syncing state will be re-rendered automatically on each new pubsub publication.
Notes
- Each JSONRPC method defined in the Wiki's spec has its own MobX store.
- The name of the observable variable in the store is the part after the
_
in the RPC method. For example, the MobX store foreth_syncing
has an observable variable namedsyncing
, the MobX store forparity_enode
has an observable variable namedenode
, etc. - Some stores have additional
@computed
properties, e.g.stores.parity.dappsUrl()
... More doc coming soon. - Each MobX store is a singleton, and can be accessed with the
.get()
method:store.eth.syncing().get()
.
