usePersisterStatus
The usePersisterStatus primitive returns a the status of a Persister, and registers a listener so that any changes to it will cause an update.
usePersisterStatus(persisterOrPersisterId?: MaybeAccessor<undefined | PersisterOrPersisterId>): Accessor<Status>| Type | Description | |
|---|---|---|
persisterOrPersisterId? | MaybeAccessor<undefined | PersisterOrPersisterId> | The |
| returns | Accessor<Status> | The status of the |
A Provider component is used to wrap part of an application in a context, and it can contain a default Persister or a set of Persister objects named by Id. The usePersisterStatus primitive lets you indicate which Persister to get data for: omit the optional parameter for the default context Persister, provide an Id for a named context Persister, or provide a Persister explicitly by reference.
When first rendered, this primitive will create a listener so that changes to the Persister status will cause an update. When the component containing this primitive is unmounted, the listener will be automatically removed.
Example
This example creates the TinyBase objects needed by the Solid primitive or component and calls it from within a reactive root.
import {createRoot} from 'solid-js';
import {
createCheckpoints,
createIndexes,
createMetrics,
createQueries,
createRelationships,
createStore,
} from 'tinybase';
import {usePersisterStatus} from 'tinybase/ui-solid';
createRoot((dispose) => {
const store = createStore()
.setTables({
pets: {
fido: {species: 'dog', color: 'brown', next: 'felix'},
felix: {species: 'cat', color: 'black'},
},
species: {dog: {price: 5}, cat: {price: 4}},
})
.setValues({open: true});
const metrics = createMetrics(store).setMetricDefinition(
'highestPrice',
'species',
'max',
'price',
);
const indexes = createIndexes(store).setIndexDefinition(
'bySpecies',
'pets',
'species',
);
const relationships = createRelationships(store)
.setRelationshipDefinition('petSpecies', 'pets', 'species', 'species')
.setRelationshipDefinition('nextPet', 'pets', 'pets', 'next');
const queries = createQueries(store).setQueryDefinition(
'petColors',
'pets',
({select, where, param}) => {
select('color');
where((getCell) => getCell('species') == param('species'));
},
{species: 'dog'},
);
const checkpoints = createCheckpoints(store);
store.setCell('pets', 'fido', 'color', 'walnut');
checkpoints.setCheckpoint('updated color');
metrics.getMetric('highestPrice');
indexes.getSliceIds('bySpecies');
relationships.getRemoteRowId('petSpecies', 'fido');
queries.getResultRowIds('petColors');
usePersisterStatus();
dispose();
});
