useSetPartialValuesCallback
The useSetPartialValuesCallback primitive returns a parameterized callback that can be used to set partial Values data in the Store, leaving other Values unaffected.
useSetPartialValuesCallback<Parameter>(
getPartialValues: (parameter: Parameter, store: Store) => Values,
storeOrStoreId?: MaybeAccessor<undefined | StoreOrStoreId>,
then?: (store: Store, partialValues: Values) => void,
): ParameterizedCallback<Parameter>| Type | Description | |
|---|---|---|
getPartialValues | (parameter: Parameter, store: Store) => Values | A function which returns the partial |
storeOrStoreId? | MaybeAccessor<undefined | StoreOrStoreId> | The |
then? | (store: Store, partialValues: Values) => void | A function which is called after the mutation, with a reference to the |
| returns | ParameterizedCallback<Parameter> | A parameterized callback for subsequent use. |
This primitive is useful, for example, when creating an event handler that will mutate the data in the Store. In this case, the parameter will likely be the event, so that you can use data from it as part of the mutation.
The third parameter is a function which will produce the partial Values object that will then be used to update the Store in the callback.
For convenience, you can optionally provide a then function which will be called just after the Store has been updated. This is a useful place to call the addCheckpoint method, for example, if you wish to add the mutation to your application's undo stack.
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 {useSetPartialValuesCallback} 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');
useSetPartialValuesCallback(() => ({employees: 3}), store)();
dispose();
});
