Usage

Configuring method-specific drivers

did-io is meant to be a DID resolver harness for use with one or more method-specific drivers (no drivers are included by default). It uses a Chai-like plugin architecture, where each driver is loaded via didIo.use(method, driver).

That means that you need to create instances of specific driver libraries for each method that you want to use.

Creating a did-io Client Instance

const didIo = require('did-io');

// You can now specify which DID methods you want via `.use(method, driver)`

Supported Drivers

• Veres One
• did:key method

Veres One DID Method

• Veres One Method spec
• did-veres-one driver docs

const v1 = require('did-veres-one');

// See did-veres-one repo for instructions on how to set up the httpsAgent etc
const veresDriver = v1.driver({ mode: 'dev', httpsAgent, documentLoader });

// to use the did:v1 / Veres One method
didIo.use('v1', veresOneDriver);

// Now you can start using the API (inside an async function)
const didDoc = await didIo.get({did});
console.log(didDoc);

didIo.methods['v1'].generate({...});
// or
veresDriver.generate({...})

Some operations are method-specific, and can be only called on individual drivers:

Veres One Supported Operations

• register()
• get()
• update()

did:key DID Method

• did-key-driver driver docs

const keyDriver = require('did-method-key');

// to use the did:key method
didIo.use('key', keyDriver);

did-key Supported Operations

• get()
