@octokit/oauth-methods

What is @octokit/oauth-methods?

The @octokit/oauth-methods package provides a set of methods to implement GitHub OAuth authentication in Node.js applications. It simplifies the process of implementing OAuth flows, handling tokens, and managing OAuth applications.

What are @octokit/oauth-methods's main functionalities?

Creating an OAuth device code

This feature allows you to create a new OAuth device code. It's useful for devices that don't have a browser or have limited input capabilities.

{"async createOAuthDeviceCode({ clientType, clientId, scopes }) { const result = await oauthMethods.createOAuthDeviceCode({ clientType, clientId, scopes }); return result; }}

Exchanging a device code for an OAuth token

After obtaining a device code, this method can be used to exchange it for an OAuth token, completing the authentication process.

{"async exchangeDeviceCode({ clientType, clientId, deviceCode }) { const result = await oauthMethods.exchangeDeviceCode({ clientType, clientId, deviceCode }); return result; }}

Refreshing an OAuth token

This feature is used to refresh an expired OAuth token, allowing for continued access without requiring the user to re-authenticate.

{"async refreshToken({ clientType, clientId, refreshToken }) { const result = await oauthMethods.refreshToken({ clientType, clientId, refreshToken }); return result; }}

Checking a token's authentication

This method checks the validity of an OAuth token, which is useful for verifying that a token has not been revoked or expired.

{"async checkToken({ auth }) { const result = await oauthMethods.checkToken({ auth }); return result; }}

Resetting a token

This feature allows you to reset an OAuth token, which can be useful in situations where token security may be compromised.

{"async resetToken({ auth }) { const result = await oauthMethods.resetToken({ auth }); return result; }}

Other packages similar to @octokit/oauth-methods

passport-github

Passport-GitHub is a Passport strategy for authenticating with GitHub using the OAuth 2.0 API. It is similar to @octokit/oauth-methods in that it facilitates GitHub authentication, but it is designed to integrate with the Passport authentication middleware for Node.js applications.

simple-oauth2

Simple OAuth2 is a library that simplifies the process of implementing OAuth2 in Node.js applications. It provides a higher-level abstraction for OAuth2 flows compared to @octokit/oauth-methods, which is specifically tailored for GitHub OAuth authentication.

The OAuth endpoints related to user access tokens are not all part of GitHub's REST API and they behave slightly different. The methods exported by `@octokit/normalize the differences so you don't have to.

Usage

Browsers	@octokit/oauth-methods is not meant for browser usage. Some of the methods will work, but others do not have CORS headers enabled and will fail (exchangeWebFlowCode(), createDeviceCode(), exchangeDeviceCode(), refreshToken()). Also the Client Secret should not be exposed to clients as it can be used for a Person-in-the-middle attack.
Node	Install with npm install @octokit/core @octokit/oauth-methods import { exchangeWebFlowCode, createDeviceCode, exchangeDeviceCode, checkToken, refreshToken, scopeToken, resetToken, deleteToken, deleteAuthorization, } from "@octokit/oauth-methods";

OAuth Web Flow

After a user granted access to an OAuth App or GitHub App on Step 1 of GitHub's OAuth Web Flow, they get redirected to a URL controlled by your app with a ?code=... query parameter.

You can exchange that code for a user access token as described in Step 2 of GitHub's OAuth Web Flow.

Setting clientType is required because there are slight differences between "oauth-app" and "github-app". Most importantly, GitHub Apps do not support scopes.

const { data, authentication } = await exchangeWebFlowCode({
  clientType: "oauth-app",
  clientId: "1234567890abcdef1234",
  clientSecret: "1234567890abcdef12347890abcdef12345678",
  code: "code123",
  scopes: ["repo"],
});

data is the raw response data. authentication is a User Authentication object.

OAuth Device Flow

In step 1 of GitHub's OAuth Device Flow, you need to create a device and user code

const {
  data: { device_code, user_code, verification_uri },
} = await createDeviceCode({
  clientType: "oauth-app",
  clientId: "1234567890abcdef1234",
  scopes: ["repo"],
});

In step 2 of GitHub's OAuth Device Flow, the user has to enter user_code on verification_uri (https://github.com/login/device unless you use GitHub Enterprise Server).

Once the user entered the code and granted access, you can exchange the device_code for a user access token in step 3 of GitHub's OAuth Device Flow

const { data, authentication } = await exchangeDeviceCode({
  clientType: "oauth-app",
  clientId: "1234567890abcdef1234",
  code: device_code,
});

data is the raw response data. authentication is a User Authentication object.

Methods

getWebFlowAuthorizationUrl()

This is a wrapper around @octokit/oauth-authorization-url that accepts a request option instead of baseUrl for consistency with the other OAuth methods. getWebFlowAuthorizationUrl() is a synchronous method and does not send any request.

const { url } = getWebFlowAuthorizationUrl({
  clientType: "oauth-app",
  clientId: "1234567890abcdef1234",
  scopes: ["repo"],
});

Options

name	type	description
clientId	string	Required. The client ID you received from GitHub when you registered.
clientType	string	Required. Must be set to either "oauth-app" or "github-app".
redirectUrl	string	The URL in your application where users will be sent after authorization. See Redirect URLs in GitHub’s Developer Guide.
login	string	Suggests a specific account to use for signing in and authorizing the app.
scopes	array of strings	Only relevant if clientType is set to "oauth-app". An array of scope names (or: space-delimited list of scopes). If not provided, scope defaults to an empty list for users that have not authorized any scopes for the application. For users who have authorized scopes for the application, the user won't be shown the OAuth authorization page with the list of scopes. Instead, this step of the flow will automatically complete with the set of scopes the user has authorized for the application. For example, if a user has already performed the web flow twice and has authorized one token with user scope and another token with repo scope, a third web flow that does not provide a scope will receive a token with user and repo scope. Defaults to [].
state	string	An unguessable random string. It is used to protect against cross-site request forgery attacks. Defaults to Math.random().toString(36).substr(2).
allowSignup	boolean	Whether or not unauthenticated users will be offered an option to sign up for GitHub during the OAuth flow. Use false in the case that a policy prohibits signups. Defaults to true.
request	function	You can pass in your own @octokit/request instance. For usage with enterprise, set baseUrl to the REST API root endpoint. Example: import { request } from "@octokit/request"; const { url } = getWebFlowAuthorizationUrl({ clientType: "oauth-app", clientId: "1234567890abcdef1234", scopes: ["repo"], request: request.defaults({ baseUrl: "https://ghe.my-company.com/api/v3", }), });

The getWebFlowAuthorizationUrl method is synchronous and returns an object with the following properties.

name	type	description
allowSignup	boolean	Returns options.allowSignup if it was set. Defaults to true.
clientType	string	Returns options.clientType
clientId	string	Returns options.clientId.
login	string	Returns options.login if it was set. Defaults to null.
redirectUrl	string	Returns options.redirectUrl if it was set. Defaults to null.
scopes	array of strings	Only set if options.clientType is set to "oauth-app". Returns an array of strings. Returns options.scopes if it was set and turns the string into an array if a string was passed, otherwise [].
state	string	Returns options.state if it was set. Defaults to Math.random().toString(36).substr(2).
url	string	The authorization URL

3. 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

Note that the clientSecret may not be set when using exchangeDeviceCode() as clientSecret is not required for the OAuth device flow.
