If you want to define it's width and let the height to adapt automatically to keep the aspect ratio, pass 0 as height.images.webp, if webp supported by the clientī. The manipulated URI will look something like this:Ī. The URI should be the path to the original resource (e.g. This happens before the request hits the cache. Step 1: The requested image URI is manipulated in the viewer-facing function to serve appropriate dimension and format. Let’s understand what happens in these various steps 1 to 5 Amazon Simple Storage Service (Amazon S3) as origin.Two triggers namely Viewer-Request and Origin-Response which are associated to a CloudFront distribution.Refer here for more information on this!

This is how the client's code would look like: Just pass width and/or height (in px) as query params and you will get original image cropped to the requested sizes. Why would your mobile users pay the cost of loading the same big files desktop users need? You might want to serve multiple image versions. If the client is requesting an image and if the client supports webp, this construct will take care of returning a webp image (which is usually 80% lighter than the convencional jpg/png images).
The goal of this library is to take image serving performance to the next level by formatting and resizing resources. This construct library is inspired by this blog from the AWS official website and this one from web.dev, and provides a way to easily setup the required arquitecture to start serving performant images.
