> Turns GitHub REST API endpoints into generic request options

[](https://www.npmjs.com/package/@octokit/endpoint)
|
||
|
||
|
||
`@octokit/endpoint` combines [GitHub REST API routes](https://developer.github.com/v3/) with your parameters and turns them into generic request options that can be used in any request library.

Load <code>@octokit/endpoint</code> directly from <a href="https://cdn.skypack.dev">cdn.skypack.dev</a>
|
||
|
||
```html
|
||
<script type="module">
|

import { endpoint } from "https://cdn.skypack.dev/@octokit/endpoint";

Install with <code>npm install @octokit/endpoint</code>
|

|
||
```js
|

const { endpoint } = require("@octokit/endpoint");

Example for [List organization repositories](https://developer.github.com/v3/repos/#list-organization-repositories)
|
||
|
||
```js
|
||
const requestOptions = endpoint("GET /orgs/{org}/repos", {
|
||
headers: {
|
||
authorization: "token 0000000000000000000000000000000000000001",
|
||
},
|
||
org: "octokit",
|
||
type: "private",
|
||
});
|
||
```
|
||
|
||
The resulting `requestOptions` looks as follows
|
||
|
||
```json
|
||
{
|
||
"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/endpoint.js v1.2.3"
|
||
}
|
||
}
|
||
```
|
||
|
||
You can pass `requestOptions` to common request libraries
|
||
|
||
```js
|
||
const { url, ...options } = requestOptions;
|
||
// using with fetch (https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API)
|
||
fetch(url, options);
|
||
// using with request (https://github.com/request/request)
|
||
request(requestOptions);
|
||
// using with got (https://github.com/sindresorhus/got)
|
||
got[options.method](url, options);
|
||
// using with axios
|
||
axios(requestOptions);
|
||
```

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:

|
||
### `endpoint.defaults()`
|
||
|
||
Override or set default options. Example:
|
||
|
||
```js
|
||
const request = require("request");
|
||
const myEndpoint = require("@octokit/endpoint").defaults({
|
||
baseUrl: "https://github-enterprise.acme-inc.com/api/v3",
|
||
headers: {
|
||
"user-agent": "myApp/1.2.3",
|
||
authorization: `token 0000000000000000000000000000000000000001`,
|
||
},
|
||
org: "my-project",
|
||
per_page: 100,
|
||
});
|
||
|
||
request(myEndpoint(`GET /orgs/{org}/repos`));
|
||
```
|
||
|
||
You can call `.defaults()` again on the returned method, the defaults will cascade.
|
||
|
||
```js
|
||
const myProjectEndpoint = endpoint.defaults({
|
||
baseUrl: "https://github-enterprise.acme-inc.com/api/v3",
|
||
headers: {
|
||
"user-agent": "myApp/1.2.3",
|
||
},
|
||
org: "my-project",
|
||
});
|
||
const myProjectEndpointWithAuth = myProjectEndpoint.defaults({
|
||
headers: {
|
||
authorization: `token 0000000000000000000000000000000000000001`,
|
||
},
|
||
});
|
||
```
|
||
|
||
`myProjectEndpointWithAuth` now defaults the `baseUrl`, `headers['user-agent']`,
|
||
`org` and `headers['authorization']` on top of `headers['accept']` that is set
|
||
by the global default.
|
||
|
||
### `endpoint.DEFAULTS`
|
||
|
||
The current default options.
|
||
|
||
```js
|
||
endpoint.DEFAULTS.baseUrl; // https://api.github.com
|
||
const myEndpoint = endpoint.defaults({
|
||
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:
|
||
|
||
```js
|
||
const myProjectEndpoint = endpoint.defaults({
|
||
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))`.
|
||
|
||
## Special cases
|
||
|
||
<a name="data-parameter"></a>
|
||
|
||
### The `data` parameter – set request body directly
|
||
|
||
Some endpoints such as [Render a Markdown document in raw mode](https://developer.github.com/v3/markdown/#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.
|
||
|
||
```js
|
||
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](https://tools.ietf.org/html/rfc6570).
|
||
|
||
Example
|
||
|
||
```js
|
||
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!",
|
||
}
|
||
);
|
||
```
