Resolver

@iota/identity-wasm API documentation

Class: Resolver<T>

Convenience type for resolving DID documents from different DID methods.

DID documents resolved with resolve will have the type specified as generic type parameter T. With the default being CoreDocument | IToCoreDocument.

Also provides methods for resolving DID Documents associated with verifiable identity_wasm/node/identity_wasm.Credential | Credentials and identity_wasm/node/identity_wasm.Presentation | Presentations.

Configuration

The resolver will only be able to resolve DID documents for methods it has been configured for in the constructor.

Extends​

Type Parameters​

• T extends CoreDocument | IToCoreDocument

Constructors​

new Resolver()​

new Resolver<T>(config): Resolver<T>

Constructs a new Resolver.

Errors

If both a client is given and the handlers map contains the "iota" key the construction process will throw an error because the handler for the "iota" method then becomes ambiguous.

Parameters​

config​

ResolverConfig

Returns​

Resolver<T>

Inherited from​

Resolver.constructor

Methods​

resolveMultiple()​

resolveMultiple(dids): Promise<(IToCoreDocument | CoreDocument)[]>

Concurrently fetches the DID Documents of the multiple given DIDs.

Errors

  • If the resolver has not been configured to handle the method of any of the given DIDs.
  • If the resolution process of any DID fails.

Note​

  • If dids contains duplicates, these will be resolved only once and the resolved document is copied into the returned array to match the order of dids.
