svelte-oidc

An Oidc Client Component for Svelte.

Try out the demo

Getting Started

Setup an OIDC Sever

npm install @dopry/svelte-oidc

App.svelte

# App.svelte
import {
  OidcContext,
  LoginButton,
  LogoutButton,
  RefreshTokenButton,
  authError,
  accessToken,
  idToken,
  isAuthenticated,
  isLoading,
  login,
  logout,
  userInfo,
} from '@dopry/svelte-oidc';

const metadata = {
            // added to overcome missing value in auth0 .well-known/openid-configuration
            // see: https://github.com/IdentityModel/oidc-client-js/issues/1067
            // see: https://github.com/IdentityModel/oidc-client-js/pull/1068
            end_session_endpoint: `process.env.OIDC_ISSUER/v2/logout?client_id=process.env.OIDC_CLIENT_ID`,
        };
</script>

<OidcContext
 issuer="https://dev-hvw40i79.auth0.com"
 client_id="aOijZt2ug6Ovgzp0HXdF23B6zxwA6PaP"
 redirect_uri="https://darrelopry.com/svelte-oidc/"
 post_logout_redirect_uri="https://darrelopry.com/svelte-oidc/"
 metadata={metadata}
 extraOptions={{
   mergeClaims: true,
   resource: "some_identifier",
 }}
 >

  <LoginButton>Login</LoginButton>
  <LogoutButton>Logout</LogoutButton>
  <RefreshTokenButton>RefreshToken<RefreshTokenButton><br />
  <pre>isLoading: {$isLoading}</pre>
  <pre>isAuthenticated: {$isAuthenticated}</pre>
  <pre>authToken: {$accessToken}</pre>
  <pre>idToken: {$idToken}</pre>
  <pre>userInfo: {JSON.stringify($userInfo, null, 2)}</pre>
  <pre>authError: {$authError}</pre>
</OidcContext>

Sapper/SSR

This component does not natively support SSR nor can it be used for authentication in server side rendered contexts. It can be used within SSR applications as long as it is acceptable for all authentication to be client side. In order to use for client side auth in an SSR application you will need to ensure it is not rendered server side as follows.

{#if process.browser} <OidcContext> ..... </OidcContext> {/if}

SvelteKit/SSR

Same as what is needed for Sapper (see above section). To do this, we need to import in the script section:

import { browser } from '$app/env';

And in the main:

{#if browser} <OidcContext> ..... </OidcContext> {/if}

Contributing

Contributors are Welcome. There is a lot of value in a vendor neutral OIDC component for use by the Svelte and Sapper community. As a developer and product manager, I have needed to switch between Okta, Auth0, KeyCloak, IdentityServer, and Ory on multiple occasions. Vendor specific libraries are usually riddled with vendor specific assumptions that make the migration hard.
