Webpack – a static module bundler is a tool that can pack many files of different formats into one Javascript file. In addition, it transforms and minifies the Javascript code so that it takes up as little space as possible and creates the so-called dependency graph. It is based on the modular concept, which involves dividing Javascript files into smaller parts and combining them, which greatly facilitates their debugging, testing or scaling of individual modules. Webpack has a number of extensions that allow greater control over the converted files and support additional formats.
