When comparing Broccoli vs Webpack, the Slant community recommends Webpack for most people. In the question“What are the best Node.js build systems / task runners?” Webpack is ranked 2nd while Broccoli is ranked 9th. 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.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Brocfile fairly straightforward and small
Pro Rebuilds are really fast
In larger apps rebuilds get slower and slower as the size of the application increases. Broccoli deals with this by building only the files that were changed and intelligently figuring out their dependencies. This leads to rebuilds being of O(1) constant-time (in Software Engineering terms).
Pro Chainable plugins
With broccoli developers can chain plugins.
var tree = broccoli.makeTree('lib')
tree = compileCoffeeScript(tree)
tree = uglifyJS(tree)
return tree
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
Cons
Con Windows not fully supported
Con Assumptions about your project limit what you can do
Assumes you want to always output to single output directory. This directory must not exist at the time of running. It also (therefore) can't be your current directory. This puts broccoli slightly out of the class of a truly general "task runner".
Con Small community
Broccoli's community is still relatively small and not very active, at least compared to it's competitors. This leads to fewer plugins, guides and less support from developers for any problem that you may face using Broccoli.
Con Config file may be hard to understand
Due to a somewhat hard to grasp syntax, configuring Webpack may take some time.
