+# npm API
+
+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
+
+> Introduced in GitLab 11.8.
+
+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. |
+

+```
+
+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
+
+> Introduced in GitLab 11.8.
+
+Upload a package.
+
+```plaintext

+## 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
+
+> Introduced in GitLab 11.8.
+
+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"
