A collection of terms often used when talking about Jamstack and associated web technologies.
An artifact (or build artifact) is the output of a build process: the complete set of files, such as HTML, CSS, JavaScript, images and configuration, which a static site generator or other build tooling produces and which is ready to be deployed to a hosting environment or CDN.
Each deploy produces a new artifact rather than modifying the files of a previous one. Because an artifact does not change once it has been created, it represents a known version of a site which can be inspected, served, or redeployed later. This is what makes immutable deploys and instant rollbacks possible. See also Atomic deploys.
