All JWTs must conform to the JWT/JWS/JWE/JW* specifications, but applications may impose additional requirements. For example, an OpenID Connect ID Token must require certain claims and headers, restrict the use of others, set default values, etc. Anvil Connect JWT is an abstract class that can be used to define JWTs conforming to application specfic requirements.

// require the package
var JWT = require('anvil-connect-jwt');

// define a subclass
var IDToken = JWT.define({

  // default header
  header: {
    alg: 'RS256'

  // permitted headers
  headers: [

  // modify header schema
  registeredHeaders: {
    alg:   { format: 'StringOrURI', required: true, enum: ['RS256'] }

  // permitted claims
  claims: ['iss', 'sub', 'aud', 'exp', 'iat', 'nonce', 'acr', 'at_hash'],

  // modify payload schema
  registeredClaims: {
    iss:      { format: 'StringOrURI', required: true },
    sub:      { format: 'StringOrURI', required: true },
    aud:      { format: 'StringOrURI', required: true },
    exp:      { format: 'IntDate',     required: true, default: expires('day')  },
    iat:      { format: 'IntDate',     required: true, default: },
    nonce:    { format: 'String' },
    acr:      { format: 'String' },
    at_hash:  { format: 'String' }
