Delegate update

In certain contexts, you may want to allow another account to update your aggregate. This can be done by creating a Security Key.

Usage

Post an aggregate

import { ItemType } from 'aleph-sdk-ts/dist/messages/message';
import { Publish as publishAggregate } from 'aleph-sdk-ts/dist/messages/aggregate';

(async () => {
    await publishAggregate({
        account: account,
        key: 'testkey',
        content: {'a': 1},
        channel: 'TEST',
	})
})();

The message result is here

"content": { "a": 1 }

Create a Security Key

import { ItemType } from 'aleph-sdk-ts/dist/messages/message';
import { Publish as publishAggregate } from 'aleph-sdk-ts/dist/messages/aggregate';

(async () => {
    await publishAggregate({
		account: account,
		key: 'security',
		content: {'authorizations': [
			{
			   'address': '0x38533Af979CdE5b399F6375D98D318cCC3004c09',
			   'types': ['AGGREGATE'],
			   'aggregate_keys': ['testkey'],
			}
		]},
		channel: 'security',
	})
})();

As you can see, we specified the delegate account will only be able to update the testkey field of the owner's aggregates.

Update with the delegated account

const res = await publishAggregate({
	account: account, // Your delegated account
	address: '0x0BBB06C238bE7D4c5Df7BA56b7ad75a09eea5F56', // The address of message Owner
	key: 'testkey',
	content: {'a': 101},
	channel: 'TEST',
})

Checking the result

import { ItemType } from 'aleph-sdk-ts/dist/messages/message';
import { Get as getAggregate } from 'aleph-sdk-ts/dist/messages/aggregate';

(async () => {
    const fetched = await getAggregate({
		address: '0x0BBB06C238bE7D4c5Df7BA56b7ad75a09eea5F56', // The Owner account
		APIServer: 'https://api2.aleph.im'
	})
})();

When fetching the result you can see that the a key was correctly updated

{ testkey: { a: 101 }, security: { authorizations: [ [Object] ] } }
