save

Apply the changes to the entity.

This method builds the patch and applies the changes.

Atomicity

When a patch is applied, it works on an all-or-nothing basis to keep things consistent. This means that either all changes are applied together, or none are applied at all.

Signature

This method has the following signature:

patch.save(): Promise<Event>

The return is a Promise that resolves to the event that records the changes.

Example

Here is a basic example of how to use this method:

patch.set('address.city', 'New York')
  .save()
  .then(() => console.log('Patch successfully sent'));
