Usage

Browsers

Load @octokit/auth-oauth-device directly from esm.sh

<script type="module">
  import { createOAuthDeviceAuth } from "https://esm.sh/@octokit/auth-oauth-device";
</script>

Node

Install with npm install @octokit/core @octokit/auth-oauth-device

import { createOAuthDeviceAuth } from "@octokit/auth-oauth-device";

[!IMPORTANT] As we use conditional exports, you will need to adapt your tsconfig.json by setting "moduleResolution": "node16", "module": "node16".

See the TypeScript docs on package.json "exports". See this helpful guide on transitioning to ESM from @sindresorhus

For OAuth Apps

const auth = createOAuthDeviceAuth({
  clientType: "oauth-app",
  clientId: "1234567890abcdef1234",
  scopes: ["public_repo"],
  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);
  },
});

const tokenAuthentication = await auth({
  type: "oauth",
});
// resolves with
// {
//   type: "token",
//   tokenType: "oauth",
//   clientType: "oauth-app",
//   clientId: "1234567890abcdef1234",
//   token: "...", /* the created oauth token */
//   scopes: [] /* depend on request scopes by OAuth app */
// }

For GitHub Apps

GitHub Apps do not support scopes. Client IDs of GitHub Apps have a lv1. prefix. If the GitHub App has expiring user tokens enabled, the resulting authentication object has extra properties related to expiration and refreshing the token.

const auth = createOAuthDeviceAuth({
  clientType: "github-app",
  clientId: "lv1.1234567890abcdef",
  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);
  },
});

const tokenAuthentication = await auth({
  type: "oauth",
});
// resolves with
// {
//   type: "token",
//   tokenType: "oauth",
//   clientType: "github-app",
//   clientId: "lv1.1234567890abcdef",
//   token: "...", /* the created oauth token */
// }
// or if expiring user tokens are enabled
// {
//   type: "token",
//   tokenType: "oauth",
//   clientType: "github-app",
//   clientId: "lv1.1234567890abcdef",
//   token: "...", /* the created oauth token */
//   refreshToken: "...",
//   expiresAt: "2022-01-01T08:00:0.000Z",
//   refreshTokenExpiresAt: "2021-07-01T00:00:0.000Z",
// }

createOAuthDeviceAuth(options)

The createOAuthDeviceAuth method accepts a single options parameter

The onVerification() callback can be used to pause until the user completes step 2, which might result in a better user experience.

const auth = createOAuthDeviceAuth({
  clientId: "1234567890abcdef1234",
  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");
  },
});

Must be either oauth-app or github-app. Defaults to oauth-app.

import { request } from "@octokit/request";
createOAuthDeviceAuth({
  clientId: "1234567890abcdef1234",
  clientSecret: "secret",
  request: request.defaults({
    baseUrl: "https://ghe.my-company.com/api/v3",
  }),
});

Only relevant if clientType is set to "oauth-app".

Array of scope names enabled for the token. Defaults to []. See available scopes.

auth(options)

The async auth() method returned by createOAuthDeviceAuth(options) accepts the following options

Only relevant if the clientType strategy options was set to "oauth-app"

Array of scope names enabled for the token. Defaults to what was set in the strategy options. See available scopes

Defaults to false. When set to false, calling auth(options) will resolve with a token that was previously created for the same scopes if it exists. If set to true a new token will always be created.

Authentication object

The async auth(options) method resolves to one of three possible objects

1. OAuth APP user authentication
2. GitHub APP user authentication with expiring tokens disabled
3. GitHub APP user authentication with expiring tokens 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 user authentication

GitHub APP user authentication with expiring tokens disabled

GitHub APP user authentication with expiring tokens enabled

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");

Types

import {
  OAuthAppStrategyOptions,
  OAuthAppAuthOptions,
  OAuthAppAuthentication,
  GitHubAppStrategyOptions,
  GitHubAppAuthOptions,
  GitHubAppAuthentication,
  GitHubAppAuthenticationWithExpiration,
} from "@octokit/auth-oauth-device";

How it works

GitHub's OAuth Device flow is different from the web flow in two ways

1. It does not require a URL redirect, which makes it great for devices and CLI apps
2. It does not require the OAuth client secret, which means there is no user-owned server component required.

The flow has 3 parts (see GitHub documentation)

1. @octokit/auth-oauth-device requests a device and user code
2. Then the user has to open https://github.com/login/device (or it's GitHub Enterprise Server equivalent) and enter the user code
3. While the user enters the code, @octokit/auth-oauth-device is sending requests in the background to retrieve the OAuth access token. Once the user completed step 2, the request will succeed and the token will be returned
