NPM: https://www.npmjs.com/package/xumm-oauth2-pkce

Constructor

new XummPkce('api-key-uuidv4', { options })

Options

interface XummPkceOptions {
  redirectUrl: string;      // Defaults to `document.location.href`, e.g. to add state params.
  rememberJwt: boolean;     // Defaults to `true`
  storage: Storage;         // Defaults to window.localStorage
  implicit: boolean;        // Defaults to `false`, `true` allows x-browser sign in, but it less secure
}

Samples:

Event based

Please note: please use the Event based sample (above) if possible: this is more compatible with future releases than the promise-based (await/async) method as displayed below.

See this example (source code) :)

Events (emitted)

• success = User signed in successfully, sdk.state() returns .me and .sdk objects
• retrieved = Retrieved existing session after e.g. browser refresh or mobile redirect, sdk.state() returns .me and .sdk objects
• error = Error, expected (e.g. user cancelled) or unexpected (...), returns argument error with an Error() object, sdk.state() returns null

Promise based sample

const xumm = new XummPkce("uuid-uuid-uuid-uuid");

const xummSignInHandler = (state) => {
  if (state.me) {
    const { sdk, me } = state;
    console.log("state", me);
    // Also: sdk » xumm-sdk (npm)
  }
};
// To pick up on mobile client redirects:
xumm.on("retrieved", async () => {
  console.log("Retrieved: from localStorage or mobile browser redirect");
  xummSignInHandler(await xumm.state());
});

// E.g. when clicking a button:
document.getElementById("somebutton").onclick = () => {
  xumm.authorize().then((session) => {
    xummSignInHandler(session);
  });
};
