Restore
Restore enables applications to revert to a previous state using any change set ID, providing a powerful safety net for users. This is especially useful when working with AI agents, as it provides a way to recover from unintended changes.
Examples
Restore to the last change set
import { openLix } from "@lix-js/sdk";// Get the most recent change set from the history
const lastChangeSet = await lix.db
.selectFrom("change_set")
.select(["id", "lixcol_metadata"])
.executeTakeFirstOrThrow();
// Restore the lix to that change set
await restore({ lix, to: lastChangeSet.id });
console.log("Restored to most recent change set:", lastChangeSet.id);Create and use a checkpoint
import { openLix } from "@lix-js/sdk";
// Get the most recent change set from the history
const lastChangeSet = await lix.db
.selectFrom("change_set")
.select(["id", "lixcol_metadata"])
.executeTakeFirstOrThrow();
// Restore the lix to that change set
await restore({ lix, to: lastChangeSet.id });
console.log("Restored to most recent change set:", lastChangeSet.id);// Later, you can easily find and restore to that checkpoint
const checkpoints = await selectCheckpoints({ lix });
const results = await checkpoints.execute();
if (results.length > 0) {
await restore({ lix, to: results[0].id });
console.log("Restored to checkpoint:", results[0].name);
} else {
console.log("No checkpoints available");
