Auth Token

This component handles auth for our components. This is merely a list of options and events; to see the full picture please refer to the guide on the subject.

This component must be always be used inside Connection like so:


We recommend loading this as high up your DOM tree as possible so it loads sooner (sometimes the OAuth dance can take a couple seconds, so the sooner this can start the faster it will be for users). We also recommend only placing it on the page once to avoid multiple token requests per-page.

Caching for performance

Sometimes the OAuth dance can take a couple seconds to complete. In that light, we strongly recommend caching the token somewhere so that new tokens are only requested when necessary.

Tokens are set using the manifold-token-receive event (in this example we’re using localStorage, but you may place this anywhere that persists):

document.addEventListener('manifold-token-receive', ({ detail }) => {
  if (detail.token) {
    // set new token if received
    localStorage.setItem('my-token', detail.token);
  } else {
    // if there was an error, clear saved token

Once we have a token stored somewhere, we can pass it back to the <manifold-auth-token> component on page reload:

<!-- Server-side -->
<manifold-auth-token token="<?= $token ?>"></manifold-auth-token>
<!-- JSX -->
<manifold-auth-token token={localStorage.getItem('my-token')} />

In the case of an expired token, the component will try, silently fail, request a new one, and trigger the manifold-token-receive event which should update anything listening without any interruption on the user side. Nothing is required on your part for an expired token; if you have caching set up via the manifold-token-receive event listener, your cache will be updated whenever new tokens are received.


The following custom events are emitted to document. You can listen for events like so:

document.addEventListener('manifold-token-receive', ({ detail }) => {
  // {
  //   duration: 1450,
  //   error: null,
  //   expiry: 86400000,
  //   token: "eyJhbGciOiJFUzI1NiI…"
  // }
