@octokit-next/endpoint

endpoint.js

Turns GitHub REST API endpoints into generic request options

@octokit-next/endpoint combines GitHub REST API routes with parameters and turns them into generic request options that can be used in any request library.

Usage

Browsers	Load @octokit-next/endpoint directly from cdn.skypack.dev <script type="module"> import { endpoint } from "https://cdn.skypack.dev/@octokit-next/endpoint"; </script>
Node	Install with npm install @octokit-next/endpoint import { endpoint } from "@octokit-next/endpoint";
Deno	Load @octokit-next/endpoint directly from cdn.skypack.dev, including types. import { endpoint } from "https://cdn.skypack.dev/octokit?dts";

Example for List organization repositories

const requestOptions = endpoint("GET /orgs/{org}/repos", {
  headers: {
    authorization: "token 0000000000000000000000000000000000000001",
  },
  org: "octokit",
  type: "private",
});

The resulting requestOptions looks as follows

{
  "method": "GET",
  "url": "https://api.github.com/orgs/octokit/repos?type=private",
  "headers": {
    "accept": "application/vnd.github.v3+json",
    "authorization": "token 0000000000000000000000000000000000000001",
    "user-agent": "octokit-next/endpoint.js v1.2.3"
  }
}

You can pass requestOptions to common request libraries

const { url, ...options } = requestOptions;
// https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch
fetch(url, options);
// https://github.com/sindresorhus/got
got[options.method](url, options);
// https://github.com/axios/axios
axios(requestOptions);

For PUT/POST endpoints with request body parameters, the code is slightly different

const { url, data, ...options } = requestOptions;
// https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch
fetch(url, { ...options, body: JSON.stringify(data) });
// https://github.com/sindresorhus/got
got[options.method](url, { ...options, json: data });
// https://github.com/axios/axios
axios(requestOptions);

API

endpoint(route, options) or endpoint(options)

name	type	description
route	String	If set, it has to be a string consisting of URL and the request method, e.g., GET /orgs/{org}. If it’s set to a URL, only the method defaults to GET.
options.method	String	Required unless route is set. Any supported http verb. Defaults to GET.
options.url	String	Required unless route is set. A path or full URL which may contain :variable or {variable} placeholders, e.g., /orgs/{org}/repos.
options.baseUrl	String	Defaults to https://api.github.com.
options.headers	Object	Custom headers. Passed headers are merged with defaults: headers['user-agent'] defaults to octokit-endpoint.js/1.2.3 (where 1.2.3 is the released version). headers['accept'] defaults to application/vnd.github.v3+json.
options.mediaType.format	String	Media type param, such as raw, diff, or text+json. See Media Types. Setting options.mediaType.format will amend the headers.accept value.
options.mediaType.previews	Array of Strings	Name of previews, such as mercy, symmetra, or scarlet-witch. See API Previews. If options.mediaType.previews was set as default, the new previews will be merged into the default ones. Setting options.mediaType.previews will amend the headers.accept value. options.mediaType.previews will be merged with an existing array set using .withDefaults().
options.data	Any	Set request body directly instead of setting it to JSON based on additional parameters. See "The data parameter" below.
options.request	Object	Pass custom meta information for the request. The request object will be returned as is.

All other options will be passed depending on the method and url options.

1. If the option key has a placeholder in the url, it will be used as the replacement. For example, if the passed options are {url: '/orgs/{org}/repos', org: 'foo'} the returned options.url is https://api.github.com/orgs/foo/repos.
2. If the method is GET or HEAD, the option is passed as a query parameter.
3. Otherwise, the parameter is passed in the request body as a JSON key.

Result

endpoint() is a synchronous method and returns an object with the following keys:

key	type	description
method	String	The http method. Always lowercase.
url	String	The url with placeholders replaced with passed parameters.
headers	Object	All header names are lowercased.
body	Any	The request body if one is present. Only for PATCH, POST, PUT, DELETE requests.
request	Object	Request meta option, it will be returned as it was passed into endpoint()

endpoint.withDefaults()

Override or set default options. Example:

const myEndpoint = endpoint.withDefaults({
  baseUrl: "https://github-enterprise.acme-inc.com/api/v3",
  headers: {
    "user-agent": "myApp/1.2.3",
    authorization: `token 0000000000000000000000000000000000000001`,
  },
});

const options = myEndpoint(`GET /orgs/{org}/repos`, {
  org: "my-project",
  per_page: 100,
});
// {
//   "method": "GET",
//   "url": "https://api.github.com/orgs/my-project/repos?per_page=100",
//   "headers": {
//     "accept": "application/vnd.github.v3+json",
//     "authorization": "token 0000000000000000000000000000000000000001",
//     "user-agent": "myApp/1.2.3"
//   }
// }

You can call .withDefaults() again on the returned method, the defaults will cascade.

const myEndpointWithToken2 = myEndpoint.withDefaults({
  headers: {
    authorization: `token 0000000000000000000000000000000000000002`,
  },
});

const options2 = myEndpointWithToken2(`GET /orgs/{org}/repos`, {
  org: "my-project",
  per_page: 100,
});
// {
//   "method": "GET",
//   "url": "https://api.github.com/orgs/my-project/repos?per_page=100",
//   "headers": {
//     "accept": "application/vnd.github.v3+json",
//     "authorization": "token 0000000000000000000000000000000000000002",
//     "user-agent": "myApp/1.2.3"
//   }
// }

endpoint.DEFAULTS

The current default options.

endpoint.DEFAULTS.baseUrl; // https://api.github.com
const myEndpoint = endpoint.withDefaults({
  baseUrl: "https://github-enterprise.acme-inc.com/api/v3",
});
myEndpoint.DEFAULTS.baseUrl; // https://github-enterprise.acme-inc.com/api/v3

endpoint.merge(route, options) or endpoint.merge(options)

Get the defaulted endpoint options, but without parsing them into request options:

const myProjectEndpoint = endpoint.withDefaults({
  baseUrl: "https://github-enterprise.acme-inc.com/api/v3",
  headers: {
    "user-agent": "myApp/1.2.3",
  },
  org: "my-project",
});
myProjectEndpoint.merge("GET /orgs/{org}/repos", {
  headers: {
    authorization: `token 0000000000000000000000000000000000000001`,
  },
  org: "my-secret-project",
  type: "private",
});

// {
//   baseUrl: 'https://github-enterprise.acme-inc.com/api/v3',
//   method: 'GET',
//   url: '/orgs/{org}/repos',
//   headers: {
//     accept: 'application/vnd.github.v3+json',
//     authorization: `token 0000000000000000000000000000000000000001`,
//     'user-agent': 'myApp/1.2.3'
//   },
//   org: 'my-secret-project',
//   type: 'private'
// }

endpoint.parse()

Stateless method to turn endpoint options into request options. Calling endpoint(options) is the same as calling endpoint.parse(endpoint.merge(options)).

Types

@octokit-next/endpoint supports types for all REST API endpoints across all supported targets (github.com, GitHub AE, GitHub Enterprise Server).

In order to take advantage of the types, you have to install the @octokit-next/types-rest-api* packages for the platform(s) you want to target.

For example, to get types for all of github.com's REST API endpoints, use @octokit-next/types-rest-api.

/// <reference types="@octokit-next/types-rest-api" />

import { endpoint } from "@octokit-next/endpoint";

endpoint("");
// Set cursor in the route argument and press `Ctrl + Space` to get a type ahead for all 700+ REST API endpoints

const requestOptions = endpoint("GET /orgs/{org}/repos", { org: "octokit" });
// requestOptions.method is now typed as `"GET"` instead of `string`
// requestOptions.url is now typed as `"/orgs/{org}/repos"` instead of `string`
// requestOptions.data does not exist on types.

To support GitHub Enterprise Server 3.0 and all new versions, import @octokit-next/types-rest-api-ghes-3.0 and set the request version:

/// <reference types="@octokit-next/types-rest-api-ghes-3.0" />

import { endpoint } from "@octokit-next/endpoint";

endpoint("", {
  request: {
    version: "ghes-3.0",
  },
});
// Set cursor in the route argument and press `Ctrl + Space` to get a type ahead for all GHES 3.0 REST API endpoints

const requestOptions = endpoint("GET /admin/users/{username}", {
  request: {
    version: "ghes-3.0",
  },
  username: "octocat",
});
// requestOptions.method is now typed as `"GET"` instead of `string`
// requestOptions.url is now typed as `"/admin/users/{username}"` instead of `string`
// requestOptions.data does not exist on types.

Types in the @octokit-next/types-rest-api-ghes packages are additive. So you can set request.version to ghes-3.1 and ghes-3.2 as well.

The version can be set using endpoint.withDefaults() as well. You can override the version in each endpoint() call.

/// <reference types="@octokit-next/types-rest-api-ghes-3.0" />

import { endpoint } from "@octokit-next/endpoint";

const ghes30endpoint = endpoint.withDefaults({
  request: {
    version: "ghes-3.0",
  },
});

endpoint("");
// Set cursor in the route argument and press `Ctrl + Space` to get a type ahead for all GHES 3.0 REST API endpoints

If you need your script to work across github.com and a minimal GitHub Enterprise Server version, you can use any of the @octokit-next/types-rest-api-ghes-*-compatible packages.

/// <reference types="@octokit-next/types-rest-api-ghes-3.0-compatible" />

import { endpoint } from "@octokit-next/endpoint";

const ghes30endpoint = endpoint.withDefaults({
  request: {
    version: "ghes-3.0",
  },
});

endpoint("");
// Set cursor in the route argument and press `Ctrl + Space` to get a type ahead for all REST API endpoints
// that exist in both github.com and GitHub Enterprise Server 3.0

Special cases

The data parameter – set request body directly

Some endpoints such as Render a Markdown document in raw mode don’t have parameters that are sent as request body keys, instead, the request body needs to be set directly. In these cases, set the data parameter.

const options = endpoint("POST /markdown/raw", {
  data: "Hello world github/linguist#1 **cool**, and #1!",
  headers: {
    accept: "text/html;charset=utf-8",
    "content-type": "text/plain",
  },
});

// options is
// {
//   method: 'post',
//   url: 'https://api.github.com/markdown/raw',
//   headers: {
//     accept: 'text/html;charset=utf-8',
//     'content-type': 'text/plain',
//     'user-agent': userAgent
//   },
//   body: 'Hello world github/linguist#1 **cool**, and #1!'
// }

Set parameters for both the URL/query and the request body

There are API endpoints that accept both query parameters as well as a body. In that case, you need to add the query parameters as templates to options.url, as defined in the RFC 6570 URI Template specification.

Example

endpoint(
  "POST https://uploads.github.com/repos/octocat/Hello-World/releases/1/assets{?name,label}",
  {
    name: "example.zip",
    label: "short description",
    headers: {
      "content-type": "text/plain",
      "content-length": 14,
      authorization: `token 0000000000000000000000000000000000000001`,
    },
    data: "Hello, world!",
  }
);
