What is Vue-loader in Vue.js?

The Vue-loader is a loader module for webpack in Vue.js that is used to write single file components using the .vue file format.

The single-file component contains three sections called template, script, and style. The webpack can extract and process each section using separate loader modules such as the SASS or SCSS loaders. The vue-loader module makes static assets to be treated as module dependencies and enables processing using webpack loaders.
