# auth-oauth-user.js > Octokit authentication strategy for OAuth user authentication [![@latest](https://img.shields.io/npm/v/@octokit/auth-oauth-user.svg)](https://www.npmjs.com/package/@octokit/auth-oauth-user) [![Build Status](https://github.com/octokit/auth-oauth-user.js/workflows/Test/badge.svg)](https://github.com/octokit/auth-oauth-user.js/actions?query=workflow%3ATest+branch%3Amain) **Important:** `@octokit/auth-oauth-user` requires your app's `client_secret`, which must not be exposed. If you are looking for an OAuth user authentication strategy that can be used on a client (browser, IoT, CLI), check out [`@octokit/auth-oauth-user-client`](https://github.com/octokit/auth-oauth-user-client.js#readme). Note that `@octokit/auth-oauth-user-client` requires a backend. The only exception is [`@octokit/auth-oauth-device`](https://github.com/octokit/auth-oauth-device.js#readme) which does not require the `client_secret`, but does not work in browsers due to CORS constraints.

Browsers Load `@octokit/auth-oauth-user` directly from [cdn.skypack.dev](https://cdn.skypack.dev) ```html ```
Node Install with `npm install @octokit/auth-oauth-user` ```js const { createOAuthUserAuth } = require("@octokit/auth-oauth-user"); ```
### Exchange code from OAuth web flow ```js const auth = createOAuthUserAuth({ clientId: "1234567890abcdef1234", clientSecret: "1234567890abcdef1234567890abcdef12345678", code: "code123", // optional state: "state123", redirectUrl: "https://acme-inc.com/login", }); // Exchanges the code for the user access token authentication on first call // and caches the authentication for successive calls const { token } = await auth(); ``` About [GitHub's OAuth web flow](https://docs.github.com/en/developers/apps/authorizing-oauth-apps#web-application-flow) ### OAuth Device flow ```js const auth = createOAuthUserAuth({ clientId: "1234567890abcdef1234", clientSecret: "1234567890abcdef1234567890abcdef12345678", onVerification(verification) { // verification example // { // device_code: "3584d83530557fdd1f46af8289938c8ef79f9dc5", // user_code: "WDJB-MJHT", // verification_uri: "https://github.com/login/device", // expires_in: 900, // interval: 5, // }; console.log("Open %s", verification.verification_uri); console.log("Enter code: %s", verification.user_code); }, }); // resolves once the user entered the `user_code` on `verification_uri` const { token } = await auth(); ``` About [GitHub's OAuth device flow](https://docs.github.com/en/developers/apps/authorizing-oauth-apps#device-flow) ### Use an existing authentication ```js const auth = createOAuthUserAuth({ clientId: "1234567890abcdef1234", clientSecret: "1234567890abcdef1234567890abcdef12345678", clientType: "oauth-app", token: "token123", }); // will return the passed authentication const { token } = await auth(); ``` See [Authentication object](#authentication-object). ## Usage with Octokit
Browsers `@octokit/auth-oauth-user` cannot be used in the browser. It requires `clientSecret` to be set which must not be exposed to clients, and some of the OAuth APIs it uses do not support CORS.
Node Install with `npm install @octokit/core @octokit/auth-oauth-user`. Optionally replace `@octokit/core` with a compatible module ```js const { Octokit } = require("@octokit/core"); const { createOAuthUserAuth } = require("@octokit/auth-oauth-user"); ```
```js const octokit = new Octokit({ authStrategy: createOAuthUserAuth, auth: { clientId: "1234567890abcdef1234", clientSecret: "1234567890abcdef1234567890abcdef12345678", code: "code123", }, }); // Exchanges the code for the user access token authentication on first request // and caches the authentication for successive requests const { data: { login }, } = await octokit.request("GET /user"); console.log("Hello, %s!", login); ``` ## `createOAuthUserAuth(options)` or `new Octokit({ auth })` The `createOAuthUserAuth` method accepts a single `options` object as argument. The same set of options can be passed as `auth` to the `Octokit` constructor when setting `authStrategy: createOAuthUserAuth` ### When using GitHub's OAuth web flow
name type description
clientId string Required. Client ID of your GitHub/OAuth App. Find it on your app's settings page.
clientSecret string Required. Client Secret for your GitHub/OAuth App. Create one on your app's settings page.
clientType string Either "oauth-app" or "github-app". Defaults to "oauth-app".
code string **Required.** The authorization code which was passed as query parameter to the callback URL from [GitHub's OAuth web application flow](https://docs.github.com/en/developers/apps/authorizing-oauth-apps#web-application-flow).
state string The unguessable random string you provided in [Step 1 of GitHub's OAuth web application flow](https://docs.github.com/en/developers/apps/authorizing-oauth-apps#1-request-a-users-github-identity).
redirectUrl string The redirect_uri parameter you provided in [Step 1 of GitHub's OAuth web application flow](https://docs.github.com/en/developers/apps/authorizing-oauth-apps#1-request-a-users-github-identity).
request function You can pass in your own @octokit/request instance. For usage with enterprise, set baseUrl to the API root endpoint. Example: ```js const { request } = require("@octokit/request"); createOAuthAppAuth({ clientId: "1234567890abcdef1234", clientSecret: "1234567890abcdef1234567890abcdef12345678", request: request.defaults({ baseUrl: "https://ghe.my-company.com/api/v3", }), }); ```
### When using GitHub's OAuth device flow
name type description
clientId string Required. Client ID of your GitHub/OAuth App. Find it on your app's settings page.
clientSecret string Required. Client Secret for your GitHub/OAuth App. The clientSecret is not needed for the OAuth device flow itself, but it is required for resetting, refreshing, and invalidating a token. Find the Client Secret on your app's settings page.
clientType string Either "oauth-app" or "github-app". Defaults to "oauth-app".
onVerification function **Required**. A function that is called once the device and user codes were retrieved The `onVerification()` callback can be used to pause until the user completes step 2, which might result in a better user experience. ```js const auth = createOAuthUserAuth({ clientId: "1234567890abcdef1234", clientSecret: "1234567890abcdef1234567890abcdef12345678", onVerification(verification) { console.log("Open %s", verification.verification_uri); console.log("Enter code: %s", verification.user_code); await prompt("press enter when you are ready to continue"); }, }); ```

request function You can pass in your own @octokit/request instance. For usage with enterprise, set baseUrl to the API root endpoint. Example: ```js const { request } = require("@octokit/request"); createOAuthAppAuth({ clientId: "1234567890abcdef1234", clientSecret: "1234567890abcdef1234567890abcdef12345678", request: request.defaults({ baseUrl: "https://ghe.my-company.com/api/v3", }), }); ```
## `auth(options)` or `octokit.auth(options)` The async `auth()` method is returned by `createOAuthUserAuth(options)` or set on the `octokit` instance when the `Octokit` constructor was called with `authStrategy: createOAuthUserAuth`. Once `auth()` receives a valid authentication object it caches it in memory and uses it for subsequent calls. It also caches if the token is invalid and no longer tries to send any requests. If the authentication is using a refresh token, a new token will be requested as needed. Calling `auth({ type: "reset" })` will replace the internally cached authentication. Resolves with an [authentication object](#authentication-object).
name type description
type string Without setting `type` auth will return the current authentication object, or exchange the `code` from the strategy options on first call. If the current authentication token is expired, the tokens will be refreshed. Possible values for `type` are - `"get"`: returns the token from internal state and creates it if none was created yet - `"check"`: sends request to verify the validity of the current token - `"reset"`: invalidates current token and replaces it with a new one - `"refresh"`: GitHub Apps only, and only if expiring user tokens are enabled. - `"delete"`: invalidates current token - `"deleteAuthorization"`: revokes OAuth access for application. All tokens for the current user created by the same app are invalidated. The user will be prompted to grant access again during the next OAuth web flow.
## Authentication object There are three possible results 1. [OAuth APP authentication token](#oauth-app-authentication-token) 1. [GitHub APP user authentication token with expiring disabled](#github-app-user-authentication-token-with-expiring-disabled) 1. [GitHub APP user authentication token with expiring enabled](#github-app-user-authentication-token-with-expiring-enabled) The differences are 1. `scopes` is only present for OAuth Apps 2. `refreshToken`, `expiresAt`, `refreshTokenExpiresAt` are only present for GitHub Apps, and only if token expiration is enabled ### OAuth APP authentication token

## `auth.hook(request, route, parameters)` or `auth.hook(request, options)` `auth.hook()` hooks directly into the request life cycle. It amends the request to authenticate correctly based on the request URL. The `request` option is an instance of [`@octokit/request`](https://github.com/octokit/request.js#readme). The `route`/`options` parameters are the same as for the [`request()` method](https://github.com/octokit/request.js#request). `auth.hook()` can be called directly to send an authenticated request ```js const { data: user } = await auth.hook(request, "GET /user"); ``` Or it can be passed as option to [`request()`](https://github.com/octokit/request.js#request). ```js const requestWithAuth = request.defaults({ request: { hook: auth.hook, }, }); const { data: user } = await requestWithAuth("GET /user"); ``` ## Types ```ts import { GitHubAppAuthentication, GitHubAppAuthenticationWithExpiration, GitHubAppAuthOptions, GitHubAppStrategyOptions, GitHubAppStrategyOptionsDeviceFlow, GitHubAppStrategyOptionsExistingAuthentication, GitHubAppStrategyOptionsExistingAuthenticationWithExpiration, GitHubAppStrategyOptionsWebFlow, OAuthAppAuthentication, OAuthAppAuthOptions, OAuthAppStrategyOptions, OAuthAppStrategyOptionsDeviceFlow, OAuthAppStrategyOptionsExistingAuthentication, OAuthAppStrategyOptionsWebFlow, } from "@octokit/auth-oauth-user"; ``` ## Contributing See [CONTRIBUTING.md](CONTRIBUTING.md) ## License [MIT](LICENSE)
