'''gulp.js''' is an open source, extensible, powerful and efficient JavaScript toolkit used as a streaming build system in front end web development. It is a task runner built on Node.js and npm, used for automation of time consuming and repetitive tasks involved in web development like minification, concatenation, cache busting, unit testing, linting, image optimization etc. gulp uses a code-over-configuration approach to define its tasks and relies on its small, single purposed plugins to carry them out.
