Managing npm overhead - strategies for handling it

When downloading packages through npm, I notice that it often includes unnecessary files along with the desired library. I usually just need the final build of the library or a *.min.js file, but end up with a lot more than that.

How do you manage these extra files? Do you manually remove them, or do you use build tools like gulp or grunt to generate the final application?

I find it confusing because my web app has numerous npm modules installed, resulting in a folder size of around 50 megabytes when it could easily be reduced to just 2mb.

Answer №1

npm install --production

By running npm install with the production flag, you can ensure that only necessary dependencies are installed, excluding any development-specific packages. Another approach is to globally set the environment to production for the server using: npm config set production.

Check out this github issue for more information. Keep in mind that this method won't provide you with just the final minified build of everything, but it will significantly reduce unnecessary bloat. For example, a library may require babel-cli, babel-preset-es2015, and uglifyjs for building purposes (devDependency), but these are not needed if the library already includes the transpiled minified file.

Managing Packages Efficiently

When it comes to handling front end non-development packages, my go-to choice is Bower. It effectively manages both minified and non-minified versions of your packages.

Optimal Build Tools

Consider using either Gulp or Grunt, with Gulp being my personal favorite. Implementing Gulp tasks can significantly enhance your code:

  • minifying css and js files
  • compressing and optimizing images
  • concatenating and caching for reduced server calls
  • versioning packages
  • automatically injecting project dependencies
  • automatically adding external dependencies
  • conducting static analysis on js and css
  • automated builds upon code changes
  • facilitating deployment processes
  • ensuring proper testing procedures

Utilizing Node.js

If possible, rely on Node.js for all your development tools and utilize Bower for release plugins. Many node packages used in production apps have corresponding Bower installations.

Additional Notes


It's advisable not to manually remove anything from Node without understanding potential dependencies. To clean up unnecessary clutter, consider using npm rimraf to delete the node_modules folder followed by npm install. Ensure to review your package.json to eliminate any unneeded saved packages.
