+ If you haven't already, you can install the [Transformers.js](https://huggingface.co/docs/transformers.js) JavaScript library from [NPM](https://www.npmjs.com/package/@huggingface/transformers) using:
11
+ ```bash
12
+ npm i @huggingface/transformers

+ **Example:** Perform image feature extraction.
16
+
17
+ ```js
18
+ import { pipeline } from '@huggingface/transformers';
19
+
20
+ const image_feature_extractor = await pipeline('image-feature-extraction', 'Xenova/tiny-random-Swin2SRModel');
