Installing the ID DWN SDK

The entire ID DWN library is available on npmjs.com To install the library, simply run either:

npm i @dwn-protocol/dwn

or

yarn add @dwn-protocol/dwn

Instantiate the DWN from the SDK

import { IDDwn } from './browser.mjs'; // browser version only
// OR
import { IDDwn } from '@dwn-protocol/dwn'; // node version

let idDwn = new IDDwn;

Create a decentralized identity (DID)

const did = await idDwn.did.create('ion');

Store the DID

await idDwn.did.manager.set(did.id, {
  connected: true,
  endpoint: 'app://dwn',
  keys: {
    ['#dwn']: 
      {
        keyPair: did.keys.find(key => key.id === 'dwn').keyPair,
      },
    },
});

Create some data

const {record} = await idDwn.dwn.records.create(did.id, {
  author: did.id,
  data: "Hello ID++",
  message: {
    dataFormat: 'text/plain',
  },
});

Read the data

const readResult = await record.data.text();

Update the data

const updateResult = await record.update({data: "Hello, I'm updated!"});

Delete the data

const deleteResult = await record.delete();
