When comparing Webpack vs Component, the Slant community recommends Webpack for most people. In the question“What are the best open source front-end package managers?” Webpack is ranked 2nd while Component is ranked 10th. The most important reason people chose Webpack is:
Plugins and loaders are easy to write and allow you to control each step of the build, from loading and compiling CoffeeScript, LESS and JADE files to smart post processing and asset manifest building.
Ranked in these QuestionsQuestion Ranking
Pros
Pro Rich and flexible plugin infrastructure
Plugins and loaders are easy to write and allow you to control each step of the build, from loading and compiling CoffeeScript, LESS and JADE files to smart post processing and asset manifest building.
Pro Tap into npm's huge module ecosystem
Using Webpack opens you up to npm, that has over 80k modules of which a great amount work both client-side and server-side. And the list is growing rapidly.
Pro Can create a single bundle or multiple chunks loaded on demand, to reduce initial loading time
Webpack allows you to split your codebase into multiple chunks. Chunks are loaded on demand. This reduces the initial loading time.
Pro Supports source maps for easier debugging
Source maps allow for easier debugging, because they allow you to find the problems within the origin files instead of the output file.
Pro ES6 module support
Webpack supports ES6 modules and their import
and export
methods without having to compile them to CommonJS require
Pro Share the same modules client-side and server-side
Because Webpack allows you to use the same require() function as node.js, you can easily share modules between the client-side and server-side.
Pro Bundles CommonJs and AMD modules (even combined)
Webpack supports AMD and CommonJS module styles. It performs clever static analysis on the AST of your code. It even has an evaluation engine to evaluate simple expressions. This allows you to support most existing libraries.
Pro Mix ES6 AMD and CommonJS
Webpack supports using all three module types, even in the same file.
Pro Limit plugin integration issues
Pro Vertically integrated with the build process
Component handles more than just package management; it also deals with the build process and bundling, so you don't have to find and manage a separate solution. This lets you get up and running faster with less to worry about.
Pro Also manages non javascript components
Components can be html snippets or css in addition to Javascript, and are treated as first class objects by being converted into Javascript modules that load styles and markup as strings.
Pro Components are more structured and thus have more inter-compatibility
Components can be javascript, style and markup, they are bundled in a way that makes it possible to load in entire UI chunks. This means less flexibility, but the components that are available are easier to work with.
Pro Designed with ES6 modules and Web Components in mind
Component is designed as a current-day solution for the currently proposed ES6 modules and Web Components, making it more in-line with the direction the web is going in the future.
Pro Encourages simpler and smaller components
Components are encouraged by convention to be small and single-use, meaning that the packages in the community's ecosystem are easier to use and combine together. More complex components use dependency resolution to compose smaller components so that components stay limited in scope.
Pro Easy dependency management
Component provides you with a flat dependency tree. This results in easy dependency management. A flat dependency tree is important for file size optimization, so you don't end up loading multiple copies of the same library, or deeply nested dependencies that bloat up.
Cons
Con Config file may be hard to understand
Due to a somewhat hard to grasp syntax, configuring Webpack may take some time.
Con Can not load files discovered during runtime
Con No longer maintained
Component is no longer being developed/maintained, so there will be no new features or bug fixes.
Con Cannot add modules that are not on Github
While using Github as a backend database for Component makes things a lot easier, as there's no need to add other authorization credentials to use modules, it means that modules that aren't on Github cannot be added.
