@octokit/auth-oauth-user

What is @octokit/auth-oauth-user?

@octokit/auth-oauth-user is an npm package that provides OAuth user authentication for GitHub. It allows developers to authenticate users via OAuth and perform actions on behalf of the authenticated user.

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

OAuth User Authentication

This feature allows you to authenticate a user via OAuth by providing the client ID, client secret, and authorization code. The code sample demonstrates how to obtain an OAuth token for the authenticated user.

const { createOAuthUserAuth } = require('@octokit/auth-oauth-user');

const auth = createOAuthUserAuth({
  clientId: 'your-client-id',
  clientSecret: 'your-client-secret',
  code: 'authorization-code'
});

(async () => {
  const { token } = await auth();
  console.log('OAuth Token:', token);
})();

Token Authentication

This feature allows you to authenticate a user using an existing access token. The code sample demonstrates how to authenticate and retrieve the token.

const { createOAuthUserAuth } = require('@octokit/auth-oauth-user');

const auth = createOAuthUserAuth({
  clientId: 'your-client-id',
  clientSecret: 'your-client-secret',
  token: 'user-access-token'
});

(async () => {
  const { token } = await auth();
  console.log('Authenticated Token:', token);
})();

Refresh Token

This feature allows you to refresh an OAuth token using a refresh token. The code sample demonstrates how to obtain a new access token using a refresh token.

const { createOAuthUserAuth } = require('@octokit/auth-oauth-user');

const auth = createOAuthUserAuth({
  clientId: 'your-client-id',
  clientSecret: 'your-client-secret',
  refreshToken: 'user-refresh-token'
});

(async () => {
  const { token } = await auth();
  console.log('Refreshed Token:', token);
})();

Other packages similar to @octokit/auth-oauth-user

passport-github

passport-github is a Passport strategy for authenticating with GitHub using the OAuth 2.0 API. It is similar to @octokit/auth-oauth-user in that it provides OAuth authentication for GitHub, but it is designed to be used with the Passport.js authentication middleware.

simple-oauth2

simple-oauth2 is a library that provides a simple and consistent way to handle OAuth 2.0 authentication. It can be used to authenticate with various OAuth 2.0 providers, including GitHub. Unlike @octokit/auth-oauth-user, it is not specific to GitHub and can be used with other services as well.

node-oauth2-server

node-oauth2-server is a complete, framework-agnostic, OAuth2 server for Node.js. It allows you to implement OAuth 2.0 authorization and authentication in your application. While it provides more comprehensive OAuth 2.0 support, it requires more setup compared to @octokit/auth-oauth-user, which is specifically tailored for GitHub.

Octokit authentication strategy for OAuth user authentication

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. Note that @octokit/auth-oauth-user-client requires a backend. The only exception is @octokit/auth-oauth-device which does not require the client_secret, but does not work in browsers due to CORS constraints.

Node	Install with npm install @octokit/auth-oauth-user const { createOAuthUserAuth } = require("@octokit/auth-oauth-user");

Exchange code from OAuth web flow

const auth = createOAuthUserAuth({
  clientId: "1234567890abcdef1234",
  clientSecret: "1234567890abcdef1234567890abcdef12345678",

// and caches the authentication for successive calls
const { token } = await auth();

About GitHub's OAuth web flow

OAuth Device flow

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

Use an existing authentication

const auth = createOAuthUserAuth({
  clientId: "1234567890abcdef1234",
  clientSecret: "1234567890abcdef1234567890abcdef12345678",
  clientType: "oauth-app",
  token: "token123",
});

// will return the passed authentication
const { token } = await auth();

See 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 const { Octokit } = require("@octokit/core"); const { createOAuthUserAuth } = require("@octokit/auth-oauth-user");

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, %!", 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

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.

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 "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
2. GitHub APP user authentication token with expiring disabled
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

OAuth APP authentication token

name	type	description
type	string	"token"
tokenType	string	"oauth"
clientType	string	"oauth-app"
clientId	string	The app's Client ID
clientSecret	string	One of the app's client secrets
token	string	The user access token
scopes	array of strings	array of scope names enabled for the token
invalid	boolean	Either undefined or true. Will be set to true if the token was invalided explicitly or found to be invalid

GitHub APP user authentication token with expiring disabled

name	type	description
type	string	"token"
tokenType	string	"oauth"
clientType	string	"github-app"
clientId	string	The app's Client ID
clientSecret	string	One of the app's client secrets
token	string	The user access token
invalid	boolean	Either undefined or true. Will be set to true if the token was invalided explicitly or found to be invalid

GitHub APP user authentication token with expiring enabled

name	type	description
type	string	"token"
tokenType	string	"oauth"
clientType	string	"github-app"
clientId	string	The app's Client ID
clientSecret	string	One of the app's client secrets
token	string	The user access token
refreshToken	string	The refresh token
expiresAt	string	Date timestamp in ISO 8601 standard. Example: 2022-01-01T08:00:0.000Z
refreshTokenExpiresAt	string	Date timestamp in ISO 8601 standard. Example: 2021-07-01T00:00:0.000Z
invalid	boolean	Either undefined or true. Will be set to true if the token was invalided explicitly or found to be invalid

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. The route/options parameters are the same as for the request() method.

auth.hook() can be called directly to send an authenticated request

const { data: user } = await auth.hook(request, "GET /user");

Or it can be passed as option to request().

const requestWithAuth = request.defaults({
  request: {
    hook: auth.hook,
  },
});

const { data: user } = await requestWithAuth("GET /user");
