GitHub TypeScript API Library

 !npm bundle size

This library provides convenient access to the GitHub REST API from server-side TypeScript or JavaScript.

The REST API documentation can be found on docs.github.com. The full API of this library can be found in api.md.

It is generated with Stainless.

MCP Server

Use the GitHub MCP Server to enable AI assistants to interact with this API, allowing them to explore endpoints, make test requests, and use documentation to help integrate this SDK into your application.


> Note: You may need to set environment variables in your MCP client.

Installation

``sh
npm install @stainless-api/github-internal
`

Usage

The full API of this library can be found in api.md.


`js
import GitHub from '@stainless-api/github-internal';

const client = new GitHub({
authToken: process.env['GITHUB_AUTH_TOKEN'], // This is the default and can be omitted
});

const repo = await client.repos.retrieve({ owner: 'github', repo: 'docs' });

console.log(repo.id);
`

$3

There's two auth methods:
either you auth via an authToken that you already have,
or you use an appId and a privateKey to get a token via a GitHub app.
If you have a GitHub app, you can get an auth token via a static method:


`js
import GitHub from '@stainless-api/github-internal';

const { authToken, expires } = await GitHub.getAuthToken({
authMethods: [
{ owner: 'owner', appId: 'appId', privateKey: 'privateKey' },
],
owner: 'owner',
repo: 'repo',
});
`

Or you can instantiate a client,
and it'll load the auth token into the client for you.
This requires owner to be set when the client is created.


`js
import GitHub from '@stainless-api/github-internal';

const client = new GitHub({ owner: 'owner', repo: 'repo' });

await client.getAuthToken({
authMethods: [
{ owner: 'owner', appId: 'appId', privateKey: 'privateKey' },
],
});
`

$3

This library includes TypeScript definitions for all request params and response fields. You may import and use them like so:


`ts
import GitHub from '@stainless-api/github-internal';

const client = new GitHub({
authToken: process.env['GITHUB_AUTH_TOKEN'], // This is the default and can be omitted
});

const params: GitHub.RepoRetrieveParams = { owner: 'github', repo: 'docs' };
const repo: GitHub.FullRepository = await client.repos.retrieve(params);
`

Documentation for each method, request param, and response field are available in docstrings and will appear on hover in most modern editors.

Handling errors

When the library is unable to connect to the API,
or if the API returns a non-success status code (i.e., 4xx or 5xx response),
a subclass of APIError will be thrown:


`ts
const issue = await client.repos.issues
.create({
owner: 'github',
repo: 'docs',
title: 'Issue',
})
.catch(async (err) => {
if (err instanceof GitHub.APIError) {
console.log(err.status); // 400
console.log(err.name); // BadRequestError
console.log(err.headers); // {server: 'nginx', ...}
} else {
throw err;
}
});
`

Error codes are as follows:

| Status Code | Error Type |
| ----------- | -------------------------- |
| 400 | BadRequestError |
| 401 | AuthenticationError |
| 403 | PermissionDeniedError |
| 404 | NotFoundError |
| 422 | UnprocessableEntityError |
| 429 | RateLimitError |
| >=500 | InternalServerError |
| N/A | APIConnectionError |

$3

Certain errors will be automatically retried 2 times by default, with a short exponential backoff.
Connection errors (for example, due to a network connectivity problem), 408 Request Timeout, 409 Conflict,
429 Rate Limit, and >=500 Internal errors will all be retried by default.

You can use the maxRetries option to configure or disable this:


`js
// Configure the default for all requests:
const client = new GitHub({
maxRetries: 0, // default is 2
});

// Or, configure per-request:
await client.repos.issues.create({
owner: 'github',
repo: 'docs',
title: 'Issue',
}, {
maxRetries: 5,
});
`

$3

Requests time out after 1 minute by default. You can configure this with a timeout option:


`ts
// Configure the default for all requests:
const client = new GitHub({
timeout: 20 * 1000, // 20 seconds (default is 1 minute)
});

// Override per-request:
await client.repos.issues.create({
owner: 'github',
repo: 'docs',
title: 'Issue',
}, {
timeout: 5 * 1000,
});
`

On timeout, an APIConnectionTimeoutError is thrown.

Note that requests which time out will be retried twice by default.

Auto-pagination

List methods in the GitHub API are paginated.
You can use the for await … of syntax to iterate through items across all pages:

`ts
async function fetchAllRepositories(params) {
const allRepositories = [];
// Automatically fetches more pages as needed.
for await (const repository of client.repos.listForCurrentUser()) {
allRepositories.push(repository);
}
return allRepositories;
}
`

Alternatively, you can request a single page at a time:

`ts
let page = await client.repos.listForCurrentUser();
for (const repository of page.data) {
console.log(repository);
}

// Convenience methods are provided for manually paginating:
while (page.hasNextPage()) {
page = await page.getNextPage();
// ...
}
`

Advanced Usage

$3

This library supports tree shaking to reduce bundle size. Instead of importing the full client, you can create a client only including the API resources you need:

`ts
import { createClient } from '@stainless-api/github-internal/tree-shakable';
import { Repos } from '@stainless-api/github-internal/resources/repos/repos';
import { BaseIssues } from '@stainless-api/github-internal/resources/repos/issues/issues';

const client = createClient({
// Specify the resources you'd like to use ...
resources: [Repos, BaseIssues],
});

// ... then make API calls as usual.
const fullRepository = await client.repos.create({ name: 'Hello-World' });
const issue = await client.repos.issues.create({
owner: 'owner',
repo: 'repo',
title: 'Found a bug',
});
`

Each API resource has two versions, the full resource (e.g., Repos) which includes all subresources, and the base resource (e.g., BaseRepos) which does not.

The tree-shaken client is fully typed, so TypeScript will provide accurate autocomplete and prevent access to resources not included in your configuration.
The createClient function automatically infers the correct type, but you can also use the PartialGitHub type explicitly:

`ts
import GitHub from '@stainless-api/github-internal';
import { createClient, type PartialGitHub } from '@stainless-api/github-internal/tree-shakable';
import { BaseRepos } from '@stainless-api/github-internal/resources/repos/repos';

// Explicit variable type
const client: PartialGitHub<{ repos: BaseRepos }> = createClient({
resources: [BaseRepos],
/ ... /
});

// Function parameter type
async function main(client: PartialGitHub<{ repos: BaseRepos }>) {
const fullRepository = await client.repos.create({ name: 'Hello-World' });
}

// Works with any client that has the repos resource
const treeShakableClient = createClient({
resources: [BaseRepos],
/ ... /
});
const fullClient = new GitHub(/ ... /);

main(treeShakableClient); // Works
main(fullClient); // Also works
`

The "raw" Response returned by fetch() can be accessed through the .asResponse() method on the APIPromise type that all methods return.
This method returns as soon as the headers for a successful response are received and does not consume the response body, so you are free to write custom parsing or streaming logic.

You can also use the .withResponse() method to get the raw Response along with the parsed data.
Unlike .asResponse() this method consumes the body, returning once it is parsed.


`ts
const client = new GitHub();

const response = await client.repos.retrieve({ owner: 'github', repo: 'docs' }).asResponse();
console.log(response.headers.get('X-My-Header'));
console.log(response.statusText); // access the underlying Response object

const { data: repo, response: raw } = await client.repos
.retrieve({ owner: 'github', repo: 'docs' })
.withResponse();
console.log(raw.headers.get('X-My-Header'));
console.log(repo.id);
`

> [!IMPORTANT]
> All log messages are intended for debugging only. The format and content of log messages
> may change between releases.

#### Log levels

The log level can be configured in two ways:

1. Via the GITHUB_LOG environment variable
2. Using the logLevel client option (overrides the environment variable if set)

`ts
import GitHub from '@stainless-api/github-internal';

const client = new GitHub({
logLevel: 'debug', // Show all log messages
});
`

Available log levels, from most to least verbose:

- 'debug' - Show debug messages, info, warnings, and errors
- 'info' - Show info messages, warnings, and errors
- 'warn' - Show warnings and errors (default)
- 'error' - Show only errors
- 'off' - Disable all logging

At the 'debug' level, all HTTP requests and responses are logged, including headers and bodies.
Some authentication-related headers are redacted, but sensitive data in request and response bodies
may still be visible.

#### Custom logger

By default, this library logs to globalThis.console. You can also provide a custom logger.
Most logging libraries are supported, including pino, winston, bunyan, consola, signale, and @std/log. If your logger doesn't work, please open an issue.

When providing a custom logger, the logLevel option still controls which messages are emitted, messages
below the configured level will not be sent to your logger.

`ts
import GitHub from '@stainless-api/github-internal';
import pino from 'pino';

const logger = pino();

const client = new GitHub({
logger: logger.child({ name: 'GitHub' }),
logLevel: 'debug', // Send all messages to pino, allowing it to filter
});
`

This library is typed for convenient access to the documented API. If you need to access undocumented
endpoints, params, or response properties, the library can still be used.

#### Undocumented endpoints

To make requests to undocumented endpoints, you can use client.get, client.post, and other HTTP verbs.
Options on the client, such as retries, will be respected when making these requests.

`ts
await client.post('/some/path', {
body: { some_prop: 'foo' },
query: { some_query_arg: 'bar' },
});
`

#### Undocumented request params

To make requests using undocumented parameters, you may use // @ts-expect-error on the undocumented
parameter. This library doesn't validate at runtime that the request matches the type, so any extra values you
send will be sent as-is.

`ts
client.repos.retrieve({
// ...
// @ts-expect-error baz is not yet public
baz: 'undocumented option',
});
`

For requests with the GET verb, any extra params will be in the query, all other requests will send the
extra param in the body.

If you want to explicitly send an extra argument, you can do so with the query, body, and headers request
options.

#### Undocumented response properties

To access undocumented response properties, you may access the response object with // @ts-expect-error on
the response object, or cast the response object to the requisite type. Like the request params, we do not
validate or strip extra properties from the response from the API.

By default, this library expects a global fetch function is defined.

If you want to use a different fetch function, you can either polyfill the global:

`ts
import fetch from 'my-fetch';

globalThis.fetch = fetch;
`

Or pass it to the client:

`ts
import GitHub from '@stainless-api/github-internal';
import fetch from 'my-fetch';

const client = new GitHub({ fetch });
`

$3

If you want to set custom fetch options without overriding the fetch function, you can provide a fetchOptions object when instantiating the client or making a request. (Request-specific options override client options.)

`ts
import GitHub from '@stainless-api/github-internal';

const client = new GitHub({
fetchOptions: {
// RequestInit options
},
});
`

#### Configuring proxies

To modify proxy behavior, you can provide custom fetchOptions that add runtime-specific proxy
options to requests:

Node [docs]

`ts
import GitHub from '@stainless-api/github-internal';
import * as undici from 'undici';

const proxyAgent = new undici.ProxyAgent('http://localhost:8888');
const client = new GitHub({
fetchOptions: {
dispatcher: proxyAgent,
},
});
`

Bun [docs]

`ts
import GitHub from '@stainless-api/github-internal';

const client = new GitHub({
fetchOptions: {
proxy: 'http://localhost:8888',
},
});
`

Deno [docs]

`ts
import GitHub from 'npm:@stainless-api/github-internal';

const httpClient = Deno.createHttpClient({ proxy: { url: 'http://localhost:8888' } });
const client = new GitHub({
fetchOptions: {
client: httpClient,
},
});
`

Frequently Asked Questions

Semantic versioning

This package generally follows SemVer conventions, though certain backwards-incompatible changes may be released as minor versions:

1. Changes that only affect static types, without breaking runtime behavior.
2. Changes to library internals which are technically public but not intended or documented for external use. _(Please open a GitHub issue to let us know if you are relying on such internals.)_
3. Changes that we do not expect to impact the vast majority of users in practice.

We take backwards-compatibility seriously and work hard to ensure you can rely on a smooth upgrade experience.

We are keen for your feedback; please open an issue with questions, bugs, or suggestions.
