Gatsby has recently launched incremental builds in its Gatsby Cloud platform, which significantly increases preview and publishing speeds by only re-building the content that has changed, rather than the entire site. This feature allows developers to achieve build times of just 10 seconds or fewer, making it ideal for large and media-rich projects. The integration with Contentful enables seamless collaboration between content editors and developers, while also providing benefits such as content previews within Contentful, Lighthouse reports on every build, and connections to leading CDNs. To take advantage of these speed breakthroughs, Gatsby recommends using a CMS like Contentful for tight integration and detection of changes, which is now possible with the launch of incremental builds.
