Examples

SpawnDev.SpawnJS Mapping Note: The JavaScript examples below show the standard Web API usage. In SpawnDev.SpawnJS, the same API is available with C# conventions:

• Properties and methods use PascalCase (e.g., readyState becomes ReadyState)
• Events use ActionEvent with +=/-= (e.g., addEventListener("click", fn) becomes OnClick += handler)
• Async methods return Task<T> instead of Promise<T>
• Objects should be disposed with using statements
• Access via JS.Get<AuthenticatorSelection>(...) or constructor new AuthenticatorSelection(...)

Creating a password credential

const credInit = {
  id: "serpent1234", // "username" in a typical username/password pair
  name: "Serpentina", // display name for credential
  origin: "https://example.org",
  password: "the last visible dog",
};

const makeCredential = document.querySelector("#make-credential");

makeCredential.addEventListener("click", async () => {
  const cred = await navigator.credentials.create({
    password: credInit,
  });
  console.log(cred.name);
  // Serpentina
  console.log(cred.id);
  // serpent1234
  console.log(cred.password);
  // the last visible dog
});

Creating a federated credential

const credInit = {
  id: "1234",
  name: "Serpentina",
  origin: "https://example.org",
  protocol: "openidconnect",
  provider: "https://provider.example.org",
};

const makeCredential = document.querySelector("#make-credential");

makeCredential.addEventListener("click", async () => {
  const cred = await navigator.credentials.create({
    federated: credInit,
  });
  console.log(cred.name);
  console.log(cred.provider);
});

Creating a public key credential

const publicKey = {
  challenge: challengeFromServer,
  rp: { id: "acme.com", name: "ACME Corporation" },
  user: {
    id: new Uint8Array([79, 252, 83, 72, 214, 7, 89, 26]),
    name: "jamiedoe",
    displayName: "Jamie Doe",
  },
  pubKeyCredParams: [{ type: "public-key", alg: -7 }],
};

const publicKeyCredential = await navigator.credentials.create({ publicKey });
