Full changelog

Custom Image and File CDN URL generators

gatsby@4.10.0 introduced Image CDN capability for Gatsby users. For best build performance, it requires a deployed site to handle image transformations at request time instead of at build time. Until now, handling those requests required supporting the specific URL format produced by Gatsby. With this release, we’re introducing support for custom URL generators that allow you to use your own URL format. This makes it easier to integrate with existing site deployment platforms that offer Image CDN capabilities or to use self-managed Image CDNs by providing a way to generate URLs that are already in format expected by your CDN.

Adapter API now offers ability to provide custom URL generators modules for both Image CDN (gatsbyImage) and File CDN (publicUrl). gatsby-adapter-netlify@1.1.0 is optionally using this feature to make use of Netlify’s Image CDN. Be sure to check Netlify Adapter documentation for more information on how to enable and configure it.

Image and File CDN now use remote URLs for source files. It is recommended to only allow certain remote URLs to be used to prevent abuse. This version also introduced a way for source plugins that support Image and File CDN to declare a list of allowed remote URLs with the newly added addRemoteFileAllowedUrl action. Adapters will receive a list of allowed URLs to automatically configure or guide users on how to configure their deployment to allow those remote URLs.

The latest versions of Gatsby plugins - gatsby-source-contentful (v8.13.0), gatsby-source-drupal (v6.13.0), and gatsby-source-wordpress (v7.13.0) - now incorporate a new action to specify allowed remote URLs. Additionally, gatsby-adapter-netlify (v1.1.0) leverages this update to assist in configuring Netlify’s Image CDN. It ensures these remote URLs are permitted and provides informative messages if your netlify.toml file requires adjustments to support these URLs.

If you are interested in using custom URL generators in your adapter, check the source code of gatsby-adapter-netlify for a reference implementation:
