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

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/endpoint.js v1.2.3"
}
}
You can pass requestOptions
to common request libraries
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);
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 . The url is parsed using url-template.
|
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 .defaults() .
|
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.
- 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 returnedoptions.url
ishttps://api.github.com/orgs/foo/repos
. - If the
method
isGET
orHEAD
, the option is passed as a query parameter. - 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.defaults()
Override or set default options. Example:
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.
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.
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:
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
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!"
}
);
