 * Add Strava login to your page.
 *
 * ### Setup
 *
 * #### Callback URL
 * ```
 * https://example.com/api/auth/callback/strava
 * ```
 *
 * #### Configuration
 *```js
 * import Auth from "@auth/core"
 * import Strava from "@auth/core/providers/strava"
 *
 * const request = new Request(origin)
 * const response = await Auth(request, {
 *   providers: [Strava({ clientId: STRAVA_CLIENT_ID, clientSecret: STRAVA_CLIENT_SECRET })],
 * })
 * ```
 *
 * ### Resources
 *
 * - [Strava API documentation](http://developers.strava.com/docs/reference/)
 *
 * ### Notes
 *
 * By default, Auth.js assumes that the Strava provider is
 * based on the [OAuth 2](https://www.rfc-editor.org/rfc/rfc6749.html) specification.
 *
 * :::tip
 *
 * The Strava provider comes with a [default configuration](https://github.com/nextauthjs/next-auth/blob/main/packages/core/src/providers/strava.ts).
 * To override the defaults for your use case, check out [customizing a built-in OAuth provider](https://authjs.dev/guides/providers/custom-provider#override-default-options).
 *
 * :::
 *
 * :::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).
