Overview

The local-did-host is a simple Hono server designed to serve did:web documents locally, which is useful for local development. The server dynamically serves .well-known/did.json routes, enabling local testing and development of DID documents. It supports subpaths for multiple identities, such as /agent/.well-known/did.json and /controller/.well-known/did.json, served by default at 0.0.0.0:3458. The DID Documents created here are dynamic and intended only for development purposes. Static serving is more appropriate for production.

​
Installation and Setup

Generate private keys for local identities. From within the example directory (e.g., from project root: ./examples/local-did-host) execute the setup: 
pnpm run setup

​
Running the Server

Start the local server: 
pnpm run dev
The server is accessible at: http://0.0.0.0:3458

​
Available Identities

Default served identities:
EntityDID URIResolved URL
agentdid:web:0.0.0.0%3A3458:agenthttp://0.0.0.0:3458/agent/.well-known/did.json
controllerdid:web:0.0.0.0%3A3458:controllerhttp://0.0.0.0:3458/controller/.well-known/did.json

How did:web Resolution Works

Resolving a did:web DID involves fetching .well-known/did.json from the indicated domain or subpath. Examples:
  • did:web:example.com resolves to https://example.com/.well-known/did.json
  • did:web:example.com:special resolves to https://example.com/special/.well-known/did.json
