SpaceVim vs Webpacker: What are the differences?
Developers describe SpaceVim as "Like spacemacs, but for vim". SpaceVim is a Modular configuration, a bundle of custom settings and plugins, for Vim. It got inspired by spacemacs. On the other hand, Webpacker is detailed as "Use Webpack to manage app-like JavaScript modules in Rails (by Rails)". Webpacker makes it easy to use the JavaScript preprocessor and bundler Webpack to manage application-like JavaScript in Rails. It coexists with the asset pipeline, as the purpose is only to use Webpack for app-like JavaScript, not images, css, or even JavaScript Sprinkles (that all continues to live in app/assets).
SpaceVim and Webpacker are primarily classified as "Tools for Text Editors" and "JS Build Tools / JS Task Runners" tools respectively.
SpaceVim and Webpacker are both open source tools. It seems that SpaceVim with 11.5K GitHub stars and 957 forks on GitHub has more adoption than Webpacker with 4.29K GitHub stars and 893 GitHub forks.
