Is it possible to verify the necessary node_modules for the project?

Is there a more efficient method to identify and remove unnecessary node_modules packages from my create-react-app project, rather than individually checking all utilized packages and their dependencies?

I'm hoping to trim down the project's size to save storage space. The node_modules folder in particular is significantly contributing to the overall space usage, especially since it's part of a resources repository.

Answer №1

When it comes to managing repository size (assuming you're using git):

  1. git rm -r --cached ./node_modules
  2. Add /node_modules to your .gitignore file
  3. git add .
  4. git commit -m "Remove node_modules from repository"

Concerning build size:

create-react-app utilizes tree shaking, which helps minimize build size. Some packages offer more modular ways of importing, mentioned in their documentation. For instance, Material UI icons provides two import options:

// option 1
import AccessAlarmIcon from '@material-ui/icons/AccessAlarm'
import ThreeDRotation from '@material-ui/icons/ThreeDRotation'
// option 2
import { AccessAlarm, ThreeDRotation } from '@material-ui/icons'

Typically, option 1 results in a smaller bundle size.

Regarding size on your development machine:

A significant improvement can be made by switching to a tool like pnpm, which centralizes node_modules on your local machine and links to them from your project. This avoids redundant module instances.

For overall project cleanliness:

Consider utilizing a tool like depcheck to identify unused dependencies. However, this may be excessive unless it's a specific issue for your project.

Answer №2

One simple method would be to exclude the node modules by updating the gitignore file (or setting one up). Alternatively, you could consider removing any unnecessary packages if directly uninstalling is feasible
