@jolocom/local-resolver-registrar

This repository can be used as a base for defining DID resolvers (compatible with the DIF did-resolver module), as well as the corresponding registrars, for various event based DID Methods.

The exported functions are agnostic to the structure of the underlying events, but rely on a number of functions being injected upon construction. These functions provide an implementation for operations which need to be aware of the event structure, allowing for registrars / resolvers relying on different event structures (e.g. KERI, Peer DID) to be built by supplying different implementations of getIdFromEvent and create (required by the registrar), and validateEvents (required by the resolver and the registrar).

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

Usage examples

In combination with the DIF DID-Resolver:

import { getResolver, createSimpleEventDb } from "@jolocom/local-resolver-registrar";
import { Resolver } from "did-resolver";
import { validateEvents } from '@jolocom/native-core'

const dbInstance = createSimpleEventDb()

// The supported Event structures, and the logic for validating them
// is encapsulated in the implementation of validateEvents

const configuredResolver = getResolver('local')({
  validateEvents,
  dbInstance
})

const resolver = new Resolver(getResolver());
const didDocument = await resolver.resolve(did);

// didDocument now contains the corresponding Did Document in JSON form.

For an example of using the registrar / resolver modules (including an example of using an event database other than the default one) , please check out the test folder.
