NPM is compatible with any CLI the developer wants to use.
Specs
Question 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 treePro Compatible with any CLI
NPM is compatible with any CLI the developer wants to use.
Pro Plenty of helpful NPM modules/plugins
NPM has a strong community that has developed plenty of libraries and plugins that are useful to developers.
Pro Very concise configuration
NPM scripts require fewer lines of code to run a given task. This is true even when it's for running build processes. Using Unix pipes lots of tasks can be reduced to one-liners.
Pro Does not need any wrapper modules
With other task runners, you need to install wrapper modules for tools you may already have installed. When using NPM that's not necessary, to use the tools you need, just install them directly through NPM.
Pro Part of node.js distribution
Pro You're most likely using NPM already
Pro Uncomplicated package management system
When it works...
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 Custom tasks require additional keyword 'run'
Only a few standard tasks support being executed without the run keyword (e.g., npm start vs npm run customtask)
Con Not a build system, only a task runner
It is supposed to be used for running gulp, webpack or whatever. But it is not supposed to be used as a build system.
Con Passing parameters is awkward
In order to pass additional parameters to npm you must add them after -- (e.g., npm run build -- --custom='foo').
Con Badly documented
Less than bare minimum official documentation leaves users in the dark without taking often expensive external courses. Even the --help text has unpluggable gaps. One official source notes the documentation isn't adequate yet nothing has been done to fix this.
Con Lot of issues with authentication and random node problems
Unable to recover from common depencies conflicts consistantly. Error messages are not always helpful to debugging. Doesn't account well for users with different versions of node.
Con Does not run well with Windows
Since a lot of projects that use NPM as a build tool most of the time make use of Bash scripts as well. This means that open source projects that run the command npm run may run into issues when used in a Windows environment.
Con Doesn't allow you to create build process with complicated logic on its own
In complex heterogeneous app you will quickly migrate to gulp, webpack or whatever leaving to NPM only simple task running responsibility.
