IndieAuth Helper

Just some abstractions for interacting with IndieAuth sites, basically wrapping got and microformats-parser mf2 parsing, performing various validations according to the specification, and some other fiddly bits.

This is currently quite opinionated, and likely is only really useful in the context of Squeep Framework Applications.

Notable methods on the Communication class:

• static async generatePKCE(length)
  Create a code and verifier for use in an IndieAuth transaction.

• async validateProfile(url) Check that a url meets specification requirements to be a profile.

• async fetchProfile(urlObject)
  Retrieve profile information from an endpoint.

• async validateClientIdentifier(url) Check that a url meets specification requirements to be a client identifier.

• async fetchClientIdentifier(urlObject)
  Retrieve client identifier information from an endpoint.

• async fetchMicroformat(urlObject)
  Retrieve all mf2 information from an endpoint.

• async fetchJSON(urlObject)
  Retrieve json from an endpoint.

• async redeemCode(urlObj, code, codeVerifier, clientId, redirectURI) Submit a code to get a profile or ticket response.

• async introspectToken(introspectionUrlObj, authenticationHeader, token) Submit a token for introspection.

• async deliverTicket(ticketEndpointUrlObj, resourceUrlObj, subjectUrlObj, ticket) Submit a ticket offer.

• async redeemTicket(ticket, resourceUrlObj, issuerUrlObj) Exchange a ticket for an access token to the given resource.
