gatsby-remark-images-datocms

Processes images in markdown so they can be used in the production build using DatoCMS’s built-in CDN.

In the processing, it makes images responsive by:

• Adding an elastic container to hold the size of the image while it loads to avoid layout jumps.
• Generating multiple versions of images at different widths and sets the srcset and sizes of the img element so regardless of the width of the device, the correct image is downloaded.
• Converting GIF images into video elements.
• Using the “blur up” technique popularized by Medium and Facebook where a small 20px wide version of the image is shown as a placeholder until the actual image is downloaded.

Install

npm install --save gatsby-remark-images-datocms
