Questions tagged [sbt-web]

sbt-web is a plugin for Scala's SBT build system, which provides a build pipeline for client-side assets, allowing SBT to be a full-stack build tool for Scala web applications.

sbt-web provides features useful for building client-side web assets, including source file generation, an asset transformation pipeline (e.g. for minfication, gzip compression), incremental compilation, NPM compatibility, and Javascript execution engines.

While closely aligned with the Play Framework, sbt-web is compatible with any project that uses SBT for its builds. The related Webjars project allows client-side library resources to be included in the Scala build process.
