goTo

Example

This example creates a Store, a Checkpoints object, makes two changes and then goes directly to the state of the Store before the two changes. It then goes forward again one change, also using the goTo method. Finally it tries to go to a checkpoint that does not exist.

import {createCheckpoints, createStore} from 'tinybase';

const store = createStore().setTables({pets: {fido: {sold: false}}});

const checkpoints = createCheckpoints(store);
console.log(checkpoints.getCheckpointIds());
// -> [[], '0', []]

store.setCell('pets', 'fido', 'color', 'brown');
checkpoints.addCheckpoint('identification');
store.setCell('pets', 'fido', 'sold', true);
checkpoints.addCheckpoint('sale');
console.log(checkpoints.getCheckpointIds());
// -> [['0', '1'], '2', []]

checkpoints.goTo('0');
console.log(store.getTables());
// -> {pets: {fido: {sold: false}}}
console.log(checkpoints.getCheckpointIds());
// -> [[], '0', ['1', '2']]

checkpoints.goTo('1');
console.log(store.getTables());
// -> {pets: {fido: {sold: false, color: 'brown'}}}
console.log(checkpoints.getCheckpointIds());
// -> [['0'], '1', ['2']]

checkpoints.goTo('3');
console.log(store.getTables());
// -> {pets: {fido: {sold: false, color: 'brown'}}}
console.log(checkpoints.getCheckpointIds());
// -> [['0'], '1', ['2']]
