How to Upgrade All NPM Packages in a Project using ncu

If you're working on a Node.js or Next.js project and want to upgrade all your dependencies to their latest versions, here's a quick reminder guide using npm-check-updates (ncu).

Step 1: Install npm-check-updates Globally

npm install -g npm-check-updates

Step 2: Check for Available Package Updates

ncu

This shows you which packages in your package.json are outdated.

Step 3: Update package.json with the Latest Versions

ncu -u

This installs the updated versions into your node_modules.

(Optional) Clean Install

rm -rf node_modules package-lock.json

npm install

Useful if you want a clean dependency tree after upgrading.
