@jolocom/jolo-did-resolver

This module encapsulates the logic required to resolve Jolocom Identities using an instance of the Jolocom registry smart contract and an IPFS gateway. The exported interface is compatible with the DIF DID-Resolver module.

Please note that this module is not meant to be used directly, but rather through an integration with either the Jolocom Library (source), or the DIF DID-Resolver module (as shown in the example below)

Usage examples

In combination with the DIF DID-Resolver:

import { getResolver } from "@jolocom/jolo-did-resolver";
import { Resolver } from "did-resolver";

const resolver = new Resolver(getResolver());
const didDocument = await resolver.resolve(did);
// didDocument now contains the corresponding Did Document in JSON form.

A number of configuration options can be passed to the getResolver function, as shown in this example:

import { getResolver } from "@jolocom/jolo-did-resolver";
import { Resolver } from "did-resolver";

// The Ethereum gateway to use for reading the registry contract state and broadcasting transactions
const ethGatewayEndpoint = 'https://rinkeby.infura.io/v3/000085cafc1934feaa09ccb83630d5d8'

// The Ethereum address of a instance of the registry smart contract to use for anchoring / resolution
const registryContractAddress = '0xD333333333333333333AAAAAAAAAAFFFFFFFFF20'

// A public IPFS gateway which can be used to store and retrieve documents
const ipfsGatewayEndpoint = 'https://ipfs.example.com:443'

const resolver = new Resolver(getResolver(ethGatewayEndpoint, registryContractAddress, ipfsGatewayEndpoint));
const didDocument = await resolver.resolve(did);
// didDocument now contains the corresponding Did Document in JSON form.

If no arguments are passed to the getResolver() function, default arguments are used.
