Working with the latest DID spec

Protocol engineer @ Veramo

We are excited to announce a new feature release of Veramo!

This new release brings together a bunch of fixes and features that we've been working on recently, including many from the community (thank you for your contributions!).

You can get a detailed list of changes in the release description. Depending on how you're using Veramo you might be impacted by some breaking changes that had to be added in this release.

Veramo uses the latest DID spec

Since the DID spec is in a more stable state, we took the opportunity to upgrade the @veramo/did-resolver and other connected internals to match this new spec. This should not be affecting you unless you are directly using the agent.didResolve() method:

  • The return type is now DidResolutionResult instead of just DIDDocument
    • This result includes a didDocument and metadata about the document and resolution process.
    • Errors are no longer thrown by the resolution process, instead they are returned as properties of the didDocumentMetadata object.
  • Many DID resolvers (including the ones we maintain, (did:ethr and did:web) now use the verificationMethod property instead of publicKey, with the same contents.

If you are directly importing dependencies from the did-resolver / did-jwt stack, please make sure to use the latest versions of those for best compatibility.

Some changes to the CLI configuration

There are some slight changes to the @veramo/cli configuration, mostly around the veramo server. options. Check out the veramo docs to see how the CLI configuration file works.

Ngrok is no longer included

In previous version you could define ngrok configuration directly in agent.yml like so:

connect: true
authtoken: XZY
subdomain: alice-did
region: eu

From now on, if you want to have the same functionality, you need to launch ngrok separately:

ngrok http -subdomain=alice-did -region=eu --authtoken=XZY 3000

and then update agent.yml file to use the correct baseUrl

baseUrl: https://alice-did.eu.ngrok.io

Creating a default DID when initializing server

Previously this was controlled with this configuration:

create: true
messagingServiceEndpoint: /messaging

In the new version this was moved to a separate section:

# Execute during server initialization
- $require: '@veramo/remote-server?t=function#createDefaultDid'
- agent:
$ref: /agent
$ref: /constants/baseUrl
messagingServiceEndpoint: /messaging

So if you don't need this functionality, instead of setting server.defaultDID.create to false, you can simply remove this section from your config file.

New plugin for did:key

This is an additional package that allows you to create, use and resolve did:key identifiers directly in Veramo.

As always, if there are any issues, let us know abut them, and if there are questions, please use the discussions page to get them answered and stay tuned for more.
