What Bower is

Bower is a free command-line package manager for web front-end components, including HTML, CSS, JavaScript, fonts, and images. It installs packages with their versions and dependencies, recording project dependencies in bower.json. Its flat dependency graph downloads a shared dependency, such as jQuery, once when multiple packages need it. Packages can come from registry names, Git endpoints, GitHub shorthand, URLs, and local folders; the default install location is bower_components. Bower is installed with npm and requires Node.js, npm, and Git. Its JSON-based .bowerrc settings cover options such as registries, proxies, SSL, storage, and lifecycle hooks. Listed workflow integrations include Grunt, Gulp, Rails and Ruby, Java, and IDEs; third-party resolvers can add sources such as npm, Mercurial, private registries, Artifactory, and Nexus Repository. Bower installs packages but does not concatenate, minify, or otherwise process their code. The official site says Bower is maintained while recommending Yarn and Vite for front-end projects. It originated at Twitter and was released in 2012.
