    Extendable client for GitHub's REST & GraphQL APIs

    @latest Build Status

    If you need a minimalistic library to utilize GitHub's REST API and GraphQL API which you can extend with plugins as needed, then @octokit/core is a great starting point.

    If you don't need the Plugin API then using @octokit/request or @octokit/graphql directly is a good alternative.


    Browsers Load @octokit/core directly from
    <script type="module">
      import { Octokit } from "";

    Install with npm install @octokit/core

    const { Octokit } = require("@octokit/core");
    // or: import { Octokit } from "@octokit/core";

    REST API example

    // Create a personal access token at
    const octokit = new Octokit({ auth: `personal-access-token123` });
    const response = await octokit.request("GET /orgs/{org}/repos", {
      org: "octokit",
      type: "private",

    See @octokit/request for full documentation of the .request method.

    GraphQL example

    const octokit = new Octokit({ auth: `secret123` });
    const response = await octokit.graphql(
      `query ($login: String!) {
        organization(login: $login) {
          repositories(privacy: PRIVATE) {
      { login: "octokit" }

    See @octokit/graphql for full documentation of the .graphql method.


    name type description
    options.authStrategy Function Defaults to @octokit/auth-token. See Authentication below for examples.
    options.auth String or Object See Authentication below for examples.
    options.baseUrl String

    When using with GitHub Enterprise Server, set options.baseUrl to the root URL of the API. For example, if your GitHub Enterprise Server's hostname is, then set options.baseUrl to Example

    const octokit = new Octokit({
      baseUrl: "",
    options.previews Array of Strings

    Some REST API endpoints require preview headers to be set, or enable additional features. Preview headers can be set on a per-request basis, e.g.

    octokit.request("POST /repos/{owner}/{repo}/pulls", {
      mediaType: {
        previews: ["shadow-cat"],
      title: "My pull request",
      base: "main",
      head: "my-feature",
      draft: true,

    You can also set previews globally, by setting the options.previews option on the constructor. Example:

    const octokit = new Octokit({
      previews: ["shadow-cat"],
    options.request Object

    Set a default request timeout (options.request.timeout) or an http(s).Agent e.g. for proxy usage (Node only, options.request.agent).

    There are more options.request.* options, see @octokit/request options. options.request can also be set on a per-request basis.

    options.timeZone String

    Sets the Time-Zone header which defines a timezone according to the list of names from the Olson database.

    const octokit = new Octokit({
      timeZone: "America/Los_Angeles",

    The time zone header will determine the timezone used for generating the timestamp when creating commits. See GitHub's Timezones documentation.

    options.userAgent String

    A custom user agent string for your app or library. Example

    const octokit = new Octokit({
      userAgent: "my-app/v1.2.3",


    You can create a new Octokit class with customized default options.

    const MyOctokit = Octokit.defaults({
      auth: "personal-access-token123",
      baseUrl: "",
      userAgent: "my-app/v1.2.3",
    const octokit1 = new MyOctokit();
    const octokit2 = new MyOctokit();

    If you pass additional options to your new constructor, the options will be merged shallowly.

    const MyOctokit = Octokit.defaults({
      foo: {
        opt1: 1,
    const octokit = new MyOctokit({
      foo: {
        opt2: 1,
    // options will be { foo: { opt2: 1 }}

    If you need a deep or conditional merge, you can pass a function instead.

    const MyOctokit = Octokit.defaults((options) => {
      return {
        foo: Object.assign({},, { opt1: 1 }),
    const octokit = new MyOctokit({
      foo: { opt2: 1 },
    // options will be { foo: { opt1: 1, opt2: 1 }}

    Be careful about mutating the options object in the Octokit.defaults callback, as it can have unforeseen consequences.


    Authentication is optional for some REST API endpoints accessing public data, but is required for GraphQL queries. Using authentication also increases your API rate limit.

    By default, Octokit authenticates using the token authentication strategy. Pass in a token using options.auth. It can be a personal access token, an OAuth token, an installation access token or a JSON Web Token for GitHub App authentication. The Authorization header will be set according to the type of token.

    import { Octokit } from "@octokit/core";
    const octokit = new Octokit({
      auth: "mypersonalaccesstoken123",
    const { data } = await octokit.request("/user");

    To use a different authentication strategy, set options.authStrategy. A list of authentication strategies is available at octokit/authentication-strategies.js.


    import { Octokit } from "@octokit/core";
    import { createAppAuth } from "@octokit/auth-app";
    const appOctokit = new Octokit({
      authStrategy: createAppAuth,
      auth: {
        appId: 123,
        privateKey: process.env.PRIVATE_KEY,
    const { data } = await appOctokit.request("/app");

    The .auth() method returned by the current authentication strategy can be accessed at octokit.auth(). Example

    const { token } = await appOctokit.auth({
      type: "installation",
      installationId: 123,


    There are four built-in log methods

    1. octokit.log.debug(message[, additionalInfo])
    2.[, additionalInfo])
    3. octokit.log.warn(message[, additionalInfo])
    4. octokit.log.error(message[, additionalInfo])

    They can be configured using the log client option. By default, octokit.log.debug() and are no-ops, while the other two call console.warn() and console.error() respectively.

    This is useful if you build reusable plugins.

    If you would like to make the log level configurable using an environment variable or external option, we recommend the console-log-level package. Example

    const octokit = new Octokit({
      log: require("console-log-level")({ level: "info" }),


    You can customize Octokit's request lifecycle with hooks.

    octokit.hook.before("request", async (options) => {
    octokit.hook.after("request", async (response, options) => {
      console.log(`${options.method} ${options.url}: ${response.status}`);
    octokit.hook.error("request", async (error, options) => {
      if (error.status === 304) {
        return findInCache(error.response.headers.etag);
      throw error;
    octokit.hook.wrap("request", async (request, options) => {
      // add logic before, after, catch errors or replace the request altogether
      return request(options);

    See before-after-hook for more documentation on hooks.


    Octokit’s functionality can be extended using plugins. The Octokit.plugin() method accepts a plugin (or many) and returns a new constructor.

    A plugin is a function which gets two arguments:

    1. the current instance
    2. the options passed to the constructor.

    In order to extend octokit's API, the plugin must return an object with the new methods.

    // index.js
    const { Octokit } = require("@octokit/core")
    const MyOctokit = Octokit.plugin(
    const octokit = new MyOctokit({ greeting: "Moin moin" });
    octokit.helloWorld(); // logs "Moin moin, world!"
    octokit.request("GET /"); // logs "GET / - 200 in 123ms"
    // lib/my-plugin.js
    module.exports = (octokit, options = { greeting: "Hello" }) => {
      // hook into the request lifecycle
      octokit.hook.wrap("request", async (request, options) => {
        const time =;
        const response = await request(options);
          `${options.method} ${options.url}${response.status} in ${ -
        return response;
      // add a custom method
      return {
        helloWorld: () => console.log(`${options.greeting}, world!`);

    Build your own Octokit with Plugins and Defaults

    You can build your own Octokit class with preset default options and plugins. In fact, this is mostly how the @octokit/<context> modules work, such as @octokit/action:

    const { Octokit } = require("@octokit/core");
    const MyActionOctokit = Octokit.plugin(
      throttle: {
        onAbuseLimit: (retryAfter, options) => {
          /* ... */
        onRateLimit: (retryAfter, options) => {
          /* ... */
      authStrategy: require("@octokit/auth-action").createActionAuth,
      userAgent: `my-octokit-action/v1.2.3`,
    const octokit = new MyActionOctokit();
    const installations = await octokit.paginate("GET /app/installations");
