how to delete all node_modules from all packages in npm 7 workspace monorepo

Question

how can I delete all node_modules folders from all packages in an npm 7 workspace?

With Lerna we could just execute lerna clean -y but when migrating to native NPM 7+ workspaces, is there some equivalent?

Answer 1

you can execute this to do so:

npm exec --workspaces -- npx rimraf node_modules && npx rimraf node_modules

explanation:

• npm exec will execute whatever comes next
• --workspaces will execute it in all your packages in your monorepo
• -- means "here comes the command to execute"
• npx rimraf node_modules is the command that's executed in all packages: it means it will delete the node_modules folder
• && means "and then"
• npx rimraf node_modules is executed again so the root folder node_modules also get deleted

That's all! Good luck

Same for pnpm: pnpm -r exec rm -rf node_modules – Nealneala

Answer 3

I found this to work on version 10.2.3, without needing third party libraries.

npm exec --workspaces -c 'rm -rf node_modules'

You can create a custom script in package.json like this:

package.json

{
  "name": "***",
  "description": "***",
  "scripts": {
     ...
    "cleandep": "rm -rf node_modules && pnpm -r exec rm -rf node_modules"
  },
  ...
}

Then run pnpm cleandep to remove all the node_modules inside the monorepo. I believe you can do the same with any other package manager
