🛠️ Step-by-Step: Updating All Dependencies

1️⃣ Check for Outdated Packages

Before updating, see which packages are outdated:

This will show a table with current, wanted, and latest versions.

yarn outdated

---

2️⃣ Upgrade to the Latest Compatible Versions

To update all dependencies within the version range specified in package.json:

yarn upgrade

This is the safest way to update without breaking changes.

---

3️⃣ Upgrade to the Latest Versions (Even Outside Version Range)

To force updates to the absolute latest versions:

yarn upgrade --latest

🚨 Warning: This may introduce breaking changes, so be sure to test after upgrading!

---

4️⃣ Interactive Upgrade (Choose What to Update)

If you want more control, use:

yarn upgrade-interactive --latest

This gives a color-coded list to select which packages to update. 🖥️

---

5️⃣ Reinstall Everything (Optional but Recommended)

After upgrading, it's good practice to clean up and reinstall:

rm -rf node_modules yarn.lock && yarn install

This ensures all dependencies are installed correctly.

🚀 Best Practices for Safe Updates

Check the Changelog – Read package release notes before updating.
Use a Separate Branch – Always test updates before merging to production.
Run Tests – Ensure everything still works after upgrading.
Use a Lockfile – Yarn automatically maintains yarn.lock for consistency.

🔥 Wrapping Up

Keeping dependencies updated is crucial, but doing it blindly can break your app. Use Yarn’s upgrade tools to ensure a smooth, safe update process.
