sp-build-web
This package is intended to be imported directly by a gulpfile that uses the SharePoint Framework build system. It imports and configures a set of build tasks that are appropriate for a build target that will run in a web browser (e.g. versus a NodeJS environment).
This package is part of the SharePoint Framework, which is a collection of NPM packages that empower developers to create client-side experiences for Microsoft SharePoint. For more information, including complete API documentation and code samples, please visit the SharePoint Framework web site.
