# GitLab TypeScript API Library

[![NPM version](<https://img.shields.io/npm/v/@stainless-api/gitlab-internal.svg?label=npm%20(stable)>)](https://npmjs.org/package/@stainless-api/gitlab-internal) ![npm bundle size](https://img.shields.io/bundlephobia/minzip/@stainless-api/gitlab-internal)

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

The full API of this library can be found in [api.md](api.md).

It is generated with [Stainless](https://www.stainless.com/).

## MCP Server

Use the GitLab 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/gitlab-internal
```

## Usage

The full API of this library can be found in [api.md](api.md).

<!-- prettier-ignore -->
```js
import GitLab from '@stainless-api/gitlab-internal';

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

const apiEntitiesMergeRequestBasic = await client.retrieveMergeRequests({ state: 'opened' });

console.log(apiEntitiesMergeRequestBasic.id);
```

### Request & Response types

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

<!-- prettier-ignore -->
```ts
import GitLab from '@stainless-api/gitlab-internal';

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

const params: GitLab.RetrieveMergeRequestsParams = { state: 'opened' };
const apiEntitiesMergeRequestBasic: GitLab.Projects.APIEntitiesMergeRequestBasic =
  await client.retrieveMergeRequests(params);
```

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

## File uploads

Request parameters that correspond to file uploads can be passed in many different forms:

- `File` (or an object with the same structure)
- a `fetch` `Response` (or an object with the same structure)
- an `fs.ReadStream`
- the return value of our `toFile` helper

```ts
import fs from 'fs';
import GitLab, { toFile } from '@stainless-api/gitlab-internal';

const client = new GitLab();

// If you have access to Node `fs` we recommend using `fs.createReadStream()`:
await client.organizations({
  name: 'name',
  path: 'path',
  avatar: fs.createReadStream('/path/to/file'),
});

// Or if you have the web `File` API you can pass a `File` instance:
await client.organizations({
  name: 'name',
  path: 'path',
  avatar: new File(['my bytes'], 'file'),
});

// You can also pass a `fetch` `Response`:
await client.organizations({
  name: 'name',
  path: 'path',
  avatar: await fetch('https://somesite/file'),
});

// Finally, if none of the above are convenient, you can use our `toFile` helper:
await client.organizations({
  name: 'name',
  path: 'path',
  avatar: await toFile(Buffer.from('my bytes'), 'file'),
});
await client.organizations({
  name: 'name',
  path: 'path',
  avatar: await toFile(new Uint8Array([0, 1, 2]), 'file'),
});
```

## 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:

<!-- prettier-ignore -->
```ts
const apiEntitiesMergeRequestBasic = await client
  .retrieveMergeRequests({ state: 'opened' })
  .catch(async (err) => {
    if (err instanceof GitLab.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`       |

### Retries

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:

<!-- prettier-ignore -->
```js
// Configure the default for all requests:
const client = new GitLab({
  maxRetries: 0, // default is 2
});

// Or, configure per-request:
await client.retrieveMergeRequests({ state: 'opened' }, {
  maxRetries: 5,
});
```

### Timeouts

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

<!-- prettier-ignore -->
```ts
// Configure the default for all requests:
const client = new GitLab({
  timeout: 20 * 1000, // 20 seconds (default is 1 minute)
});

// Override per-request:
await client.retrieveMergeRequests({ state: 'opened' }, {
  timeout: 5 * 1000,
});
```

On timeout, an `APIConnectionTimeoutError` is thrown.

Note that requests which time out will be [retried twice by default](#retries).

## Advanced Usage

### Tree shaking

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/gitlab-internal/tree-shakable';
import { TopLevel } from '@stainless-api/gitlab-internal/resources/top-level';
import { BaseNamespaces } from '@stainless-api/gitlab-internal/resources/namespaces/namespaces';

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

// ... then make API calls as usual.
const response = await client.glql({ glql_yaml: 'glql_yaml' });
const namespace = await client.namespaces.retrieve('string');
```

Each API resource has two versions, the full resource (e.g., `TopLevel`) which includes all subresources, and the base resource (e.g., `BaseTopLevel`) 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 `PartialGitLab` type explicitly:

```ts
import GitLab from '@stainless-api/gitlab-internal';
import { createClient, type PartialGitLab } from '@stainless-api/gitlab-internal/tree-shakable';
import { BaseTopLevel } from '@stainless-api/gitlab-internal/resources/top-level';

// Explicit variable type
const client: PartialGitLab<{ client: BaseTopLevel }> = createClient({
  resources: [BaseTopLevel],
  /* ... */
});

// Function parameter type
async function main(client: PartialGitLab<{ client: BaseTopLevel }>) {
  const response = await client.glql({ glql_yaml: 'glql_yaml' });
}

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

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

### Accessing raw Response data (e.g., headers)

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.

<!-- prettier-ignore -->
```ts
const client = new GitLab();

const response = await client.retrieveMergeRequests({ state: 'opened' }).asResponse();
console.log(response.headers.get('X-My-Header'));
console.log(response.statusText); // access the underlying Response object

const { data: apiEntitiesMergeRequestBasic, response: raw } = await client
  .retrieveMergeRequests({ state: 'opened' })
  .withResponse();
console.log(raw.headers.get('X-My-Header'));
console.log(apiEntitiesMergeRequestBasic.id);
```

### Logging

> [!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 `GITLAB_LOG` environment variable
2. Using the `logLevel` client option (overrides the environment variable if set)

```ts
import GitLab from '@stainless-api/gitlab-internal';

const client = new GitLab({
  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](https://www.npmjs.com/package/pino), [winston](https://www.npmjs.com/package/winston), [bunyan](https://www.npmjs.com/package/bunyan), [consola](https://www.npmjs.com/package/consola), [signale](https://www.npmjs.com/package/signale), and [@std/log](https://jsr.io/@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 GitLab from '@stainless-api/gitlab-internal';
import pino from 'pino';

const logger = pino();

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

### Making custom/undocumented requests

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.retrieveMergeRequests({
  // ...
  // @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.

### Customizing the fetch client

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 GitLab from '@stainless-api/gitlab-internal';
import fetch from 'my-fetch';

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

### Fetch options

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 GitLab from '@stainless-api/gitlab-internal';

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

#### Configuring proxies

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