@auth/core/providers/mastodon.js

Authentication for the Web.

/**
 * Add Mastodon login to your page.
 *
 * ### Setup
 *
 * #### Callback URL
 * ```
 * https://example.com/api/auth/callback/mastodon
 * ```
 *
 * #### Configuration
 *```ts
 * import { Auth } from "@auth/core"
 * import Mastodon from "@auth/core/providers/mastodon"
 *
 * const request = new Request(origin)
 * const response = await Auth(request, {
 *   providers: [
 *     Mastodon({
 *       clientId: MASTODON_CLIENT_ID,
 *       clientSecret: MASTODON_CLIENT_SECRET,
 *       issuer: MASTODON_ISSUER,
 *     }),
 *   ],
 * })
 * ```
 *
 * ### Resources
 *
 *  - [Mastodon OAuth documentation](https://docs.joinmastodon.org/client/token/)
 *  - [Mastodon OAuth Configuration](https://mastodon.social/settings/applications)
 *
 * ### Notes
 *
 * By default, Auth.js assumes that the Mastodon provider is
 * based on the [OAuth 2](https://www.rfc-editor.org/rfc/rfc6749.html) specification.
 *
 * Due to Mastodons infrastructure beeing a Fediverse you have to define the `issuer` you want to connect to.
 *
 * :::tip
 *
 * The Mastodon provider comes with a [default configuration](https://github.com/nextauthjs/next-auth/blob/main/packages/core/src/providers/mastodon.ts).
 * To override the defaults for your use case, check out [customizing a built-in OAuth provider](https://authjs.dev/guides/configuring-oauth-providers).
 *
 * :::
 *
 * :::info **Disclaimer**
 *
 * If you think you found a bug in the default configuration, you can [open an issue](https://authjs.dev/new/provider-issue).
 *
 * Auth.js strictly adheres to the specification and it cannot take responsibility for any deviation from
 * the spec by the provider. You can open an issue, but if the problem is non-compliance with the spec,
 * we might not pursue a resolution. You can ask for more help in [Discussions](https://authjs.dev/new/github-discussions).
