@auth/core/providers/vk.js

Authentication for the Web.

/**
 * Add VK login to your page.
 *
 * ### Setup
 *
 * #### Callback URL
 * ```
 * https://example.com/api/auth/callback/vk
 * ```
 *
 * #### Configuration
 *```ts
 * import { Auth } from "@auth/core"
 * import VK from "@auth/core/providers/vk"
 *
 * const request = new Request(origin)
 * const response = await Auth(request, {
 *   providers: [VK({ clientId: VK_CLIENT_ID, clientSecret: VK_CLIENT_SECRET })],
 * })
 * ```
 *
 * ### Resources
 *
 * - [VK API documentation](https://vk.com/dev/first_guide)
 * - [VK App configuration](https://vk.com/apps?act=manage)
 *
 * ### Notes
 *
 * By default, Auth.js assumes that the VK provider is
 * based on the [OAuth 2](https://www.rfc-editor.org/rfc/rfc6749.html) specification.
 *
 * :::tip
 *
 * The VK provider comes with a [default configuration](https://github.com/nextauthjs/next-auth/blob/main/packages/core/src/providers/vk.ts).
 * To override the defaults for your use case, check out [customizing a built-in OAuth provider](https://authjs.dev/guides/configuring-oauth-providers).
 *
 * :::
 *
 * :::note
 *
 * By default the provider uses 5.126 version of the API. See https://vk.com/dev/versions for more info.
 * If you want to use a different version, you can pass it to provider's options object:
 * ```ts
 * const apiVersion = "5.126"
 * providers: [
 *   Vk({
 *     accessTokenUrl: `https://oauth.vk.com/access_token?v=${apiVersion}`,
 *     requestTokenUrl: `https://oauth.vk.com/access_token?v=${apiVersion}`,
 *     authorizationUrl:
 *       `https://oauth.vk.com/authorize?response_type=code&v=${apiVersion}`,
 *     profileUrl: `https://api.vk.com/method/users.get?fields=photo_100&v=${apiVersion}`,
 *   })
 * ]
 * ```
 *
 * :::
 *
 * :::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).
