Decentralized Identity (DID) Universal Resolver abstract driver class

Abstract

In this module we provide a base Driver class for Decentralized Identity (DID) universal resolution. This driver implements an interface similar to the reference implementation described in the universal-resolver repository. Implementors should extend this abstract class to describe their own resolution driver.

Installation

$ npm install did-universal-resolver-driver

Usage Example

const { Driver } = require('did-universal-resolver-driver')
const driver = new Driver({
  resolve(identifier) {
    // resolve identifier with ResolutionResult somehow
  },

  properties() {
    // return Map<String, Object> instance of driver resolution properties
  }
})

An implementor can extend this base class overloading the required methods for the driver.

const { Driver } = require('did-universal-resolver-driver')
class MyDriver extends Driver {
  resolve(identifier) {
    // resolve identifier with ResolutionResult somehow
  },

  properties() {
    // return Map<String, Object> instance of driver resolution properties
  }
}

API

driver = new Driver(opts)

where opts should be:

{
  resolve(identifier): ResolutionResult // Resolve identifier into a ResolutionResult
  properties(): Map<String, Object> // A Map instance of property keys to object values
}

driver.resolve(identifier)

where identifier is a DID URI.

An interface method that should be overloaded. Will throw error if not implemented.

driver.properties()

An interface method that should be overloaded. Will throw error if not implemented.
