NPM is compatible with any CLI the developer wants to use.

Pros
Pro Automatically converts files to AMD for you
Volo is based around AMD, which is great for asynchronous loading, and if you try to add a non-AMD package, it will interactively ask you for its dependencies and exports.
Pro Provides command endpoints for task management
Volo also allows you to provide a volofile that lets you run various tasks. Volo provides a helper object for running cross platform command line commands, and also allows you to use binaries in node_modules
or create your own.
Pro Quickly bootstrap your project with templates
Volo has a create
command that can copy template projects from GitHub, so you can get set up quickly.
Pro Allows for extensible commands
Sometimes you might require some additional commands, other than the ones Volo provides; Volo has you covered in these cases as well. The package manager is extremely extensible at its core, and can be easily modified and extended.
Pro Loads packages directly from Github
If any project exists on Github, that means you can use it along with Volo in your frontend projects.
Pro 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 Does not store components in a registry
Volo installs components directly from urls and repositories, which makes it more susceptible to components being taken down, with fewer guarantees about their availability.
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.
