Installation

npm install @ebsifnmt/ebsi-did-resolver

or if you use yarn:

yarn add @ebsifnmt/ebsi-did-resolver

Resolving a DID document

The library presents a resolve() function that returns a Promise returning the DID document. It is not meant to be used directly but through the did-resolver aggregator.

You can use the getResolver(config) method to produce an entry that can be used with the Resolver constructor:

import { Resolver } from "did-resolver";
import { getResolver } from "@ebsifnmt/ebsi-did-resolver";

// You must set the address of the DID Registry to be used
const resolverConfig = {
  registry: "https://api.preprod.ebsi.eu/did-registry/v2/identifiers",
};

// getResolver will return an object with a key/value pair of { "ebsi": resolver } where resolver is a function used by the generic did resolver.
const ebsiDidResolver = getResolver(resolverConfig);
const didResolver = new Resolver(ebsiDidResolver);

didResolver
  .resolve("did:ebsi:zub5ZZUfHLLptCduwEy8xRj")
  .then((doc) => console.log);

// You can also use ES7 async/await syntax
const doc = await didResolver.resolve("did:ebsi:zub5ZZUfHLLptCduwEy8xRj");
