Class: ConnectedLdoTransactionDataset\<Plugins>

A ConnectedLdoTransactionDataset has all the functionality of a ConnectedLdoDataset and represents a transaction to the parent ConnectedLdoDataset.

It is recommended to use the startTransaction method on a SolidLdoDataset to initialize this class

Example

import { createConnectedLdoDataset } from "@ldo/connected";
import { ProfileShapeType } from "./.ldo/profile.shapeTypes.ts"
import { solidConnectedPlugin } from "connected-solid";

// ...

const connectedLdoDataset = createConnectedLdoDataset([
  solidConnectedPlugin
]);

const profileDocument = connectedLdoDataset
  .getResource("https://example.com/profile");
await profileDocument.read();

const transaction = connectedLdoDataset.startTransaction();

const profile = transaction
  .using(ProfileShapeType)
  .fromSubject("https://example.com/profile#me");
profile.name = "Some Name";
const result = await transaction.commitToRemote();
if (result.isError) {
  // handle error
}
