Long story short: You are entering a world of pain.

If you’ve just opened a repo that hasn’t been touched in six months and decided to "quickly update packages," you know exactly what I’m talking about. It starts with good intentions and ends with you questioning your career choices at 2 AM.

But ignoring it isn’t a strategy—it’s just technical debt compounding daily.

Here is the no-nonsense workflow to getting your green checkmarks back without blowing up production.

Phase 1: Know Your Enemy

Before you touch the terminal, you need to understand why things break.

SemVer (Semantic Versioning): It’s a trust exercise.

• Patch/Minor (Green/Yellow): Should be backwards compatible. Usually safe.
• Major (Red): The author definitely broke something on purpose. Proceed with caution.

Node Version Drift: If you are still running Node 16 (or older), stop. You are running on unmaintained software. Most modern libraries now require Node 20 or 22 minimum.

The "Ghost" Package: Sometimes a package is just... gone. The maintainer quit. You might have to rip it out entirely.

Phase 2: The Setup

Do not start upgrading without these two safety nets.

1. Engine Locking

Stop your coworkers (or your future self) from trying to run your Node 22 project on Node 14. Add this to your package.json immediately:

"engines": {
"node": ">=20.0.0",
"pnpm": ">=9.0.0"
}

2. The "Sanity Check"

If you don’t have automated tests, you are gambling. Pure and simple. If you have zero tests, write at least one "smoke test" that checks if the app actually boots up before you start messing with dependencies.

Phase 3: The Tools (Stop doing it manually)

If you are manually changing version numbers in package.json, you are wasting your time. We have interactive tools for this now.

If you use pnpm (Standard for 2025):

pnpm update -i

If you use Yarn:

yarn upgrade-interactive

If you use npm: The native npm experience is still lacking here. Grab npm-check-updates (ncu).

npx npm-check-updates -i

Phase 4: The Strategy

When you run those commands, you’ll get a list of packages color-coded by how scary the update is.

Here is the playbook:

The "Easy Win" Sweep

Select all the Green and Yellow updates (patch/minor). Hit update. Run your tests. Commit this separately with a message like chore: update non-breaking dependencies.

The Red Zone (Major Updates)

This is where the actual work is.

• Rule #1: One at a time.
• Rule #2: Read the Changelog. Go to the GitHub releases page and Ctrl+F for "Breaking Changes."
• Rule #3: Verify. Fix the code, run the app, ensure it works.

If you try to update 5 major versions at once, you will create a dependency conflict so deep you’ll want to delete the repo. Don’t be a hero.

Decision Flow

Phase 5: The "Boss Battles"

There are two scenarios that will make you want to quit.

1. Updating Node.js itself

Moving from Node 18 to 22 isn’t just a number change. It often breaks binary dependencies (like image processors or encryption tools).

The fix: Usually, you need to nuke your node_modules and lockfile:

rm -rf node_modules pnpm-lock.yaml
pnpm install

2. The Deprecated Package

You see a warning: "This package is deprecated."

This isn’t an update task; it’s a rewrite. If a library is dead, you have to find an alternative. Do not squeeze this into your maintenance PR. Create a separate ticket for "Replace [Dead Library]" and do it later.

Pro Tip: Automate the misery

Honestly, doing this manually is labor. I feel like I should get paid double every time I resolve a peer dependency conflict.

In 2025, just set up Renovate Bot or GitHub’s Dependabot. Configure it to:

• Automatically merge patch updates (if tests pass)
• Open PRs for major updates so you can review them one by one

Summary

Take it slow. If you have a massive backlog, don’t do it all in one Friday afternoon. Chip away at it.

And if you see a red error message... well, welcome to the club.
