The best practice would be to upload image to some storage (Amazon S3, Google Cloud Storage...) and then store the url of the uploaded image to MongoDB. After you fetch data from MongoDB, just set src property of img tag to be url of the uploaded image.

If you want to go with your approach of storing Buffer in the MongoDB, you can display the base64 data in HTML like this:

<img src="data:image/png;base64, {{your_base64_data}}"/>
