# npm API **(FREE)**

This is the API documentation for [npm Packages](../../user/packages/npm_registry/index.md).

WARNING:
This API is used by the [npm package manager client](https://docs.npmjs.com/)
and is not meant for manual consumption.

For instructions on how to upload and install npm packages from the GitLab
package registry, see the [npm package registry documentation](../../user/packages/npm_registry/index.md).

NOTE:
These endpoints do not adhere to the standard API authentication methods.
See the [npm package registry documentation](../../user/packages/npm_registry/index.md)
for details on which headers and token types are supported.

## Download a package

Downloads the npm package. This URL is provided by the [metadata endpoint](#metadata).

```plaintext
GET projects/:id/packages/npm/:package_name/-/:file_name
```

| Attribute         | Type   | Required | Description |
| ----------------- | ------ | -------- | ----------- |
| `id`              | string | yes      | The ID or full path of the project. |
| `package_name`    | string | yes      | The name of the package. |
| `file_name`       | string | yes      | The name of the package file. |

```shell
curl --header "Authorization: Bearer <personal_access_token>" "https://gitlab.example.com/api/v4/projects/1/packages/npm/@myscope/my-pkg/-/@my-scope/my-pkg-0.0.1.tgz"
```

Write the output to a file:

```shell
curl --header "Authorization: Bearer <personal_access_token>" "https://gitlab.example.com/api/v4/projects/1/packages/npm/@myscope/my-pkg/-/@my-scope/my-pkg-0.0.1.tgz" >> @myscope/my-pkg-0.0.1.tgz
```

This writes the downloaded file to `@myscope/my-pkg-0.0.1.tgz` in the current directory.

## Upload a package file

Upload a package.

```plaintext
PUT projects/:id/packages/npm/:package_name
```

| Attribute      | Type   | Required | Description                         |
|----------------|--------|----------|-------------------------------------|
| `id`           | string | yes      | The ID or full path of the project. |
| `package_name` | string | yes      | The name of the package.            |
| `versions`     | string | yes      | Package version information.        |

```shell
curl --request PUT
     --header "Content-Type: application/json"
     --data @./path/to/metadata/file.json
     --header "Authorization: Bearer <personal_access_token>" \
     "https://gitlab.example.com/api/v4/projects/1/packages/npm/@myscope/my-pkg"
```

The metadata file content is generated by npm, but looks something like this:

```json

    "_attachments": {
        "@myscope/my-pkg-1.3.7.tgz": {

        }
    }
}
```

## Route prefix

For the remaining routes, there are two sets of identical routes that each make requests in
different scopes:

- Use the instance-level prefix to make requests in the scope of the entire instance.
- Use the project-level prefix to make requests in a single project's scope.

The examples in this document all use the project-level prefix.

### Instance-level

```plaintext
 /packages/npm`
```

| Attribute | Type   | Required | Description |
| --------- | ------ | -------- | ----------- |
| `id`      | string | yes      | The group ID or full group path. |

### Project-level

```plaintext
 /projects/:id/packages/npm`
```

| Attribute | Type   | Required | Description |
| --------- | ------ | -------- | ----------- |
| `id`      | string | yes      | The project ID or full project path. |

## Metadata

Returns the metadata for a given package.

```plaintext
GET <route-prefix>/:package_name
```

| Attribute      | Type   | Required | Description |
| -------------- | ------ | -------- | ----------- |
| `package_name` | string | yes      | The name of the package. |

```shell
curl --header "Authorization: Bearer <personal_access_token>" "https://gitlab.example.com/api/v4/projects/1/packages/npm/@myscope/my-pkg"
```

Example response:

```json
{
  "name": "@myscope/my-pkg",
  "versions": {
    "0.0.2": {
      "name": "@myscope/my-pkg",
      "version": "0.0.1",
      "dist": {
        "shasum": "93abb605b1110c0e3cca0a5b805e5cb01ac4ca9b",
        "tarball": "https://gitlab.example.com/api/v4/projects/1/packages/npm/@myscope/my-pkg/-/@myscope/my-pkg-0.0.1.tgz"
      }
    }
  },
  "dist-tags": {
    "latest": "0.0.1"
  }
}
```

The URLs in the response have the same route prefix used to request them. If you request them with
the instance-level route, the returned URLs contain `/api/v4/packages/npm`.

## Dist-Tags

### List tags

> Introduced in GitLab 12.7.

Lists the dist-tags for the package.

```plaintext
GET <route-prefix>/-/package/:package_name/dist-tags

| `package_name` | string | yes      | The name of the package. |

```shell
curl --header "Authorization: Bearer <personal_access_token>" "https://gitlab.example.com/api/v4/projects/1/packages/npm/-/package/@myscope/my-pkg/dist-tags"
```

Example response:

```json
{
  "latest": "2.1.1",
  "stable": "1.0.0"
}
```

The URLs in the response have the same route prefix used to request them. If you request them with
the instance-level route, the returned URLs contain `/api/v4/packages/npm`.

### Create or update a tag
