years and years of old code, things added to themes, etc.

Topic summary

A store owner is concerned about accumulated code and unused app remnants in their theme over the years, suspecting it’s affecting site performance. They’re hesitant to remove anything due to limited technical knowledge.

Suggested approach:

  • Duplicate the production theme first as a safety backup
  • Identify mission-critical apps and create a list of potentially unnecessary ones
  • Deactivate apps gradually, one at a time rather than all at once
  • Monitor the web performance dashboard for 1-2 weeks after each change to catch any issues
  • Restore quickly if problems arise

Key insight: This “tech debt” is normal for any long-running website. The solution is incremental cleanup rather than attempting a complete overhaul, treating it as an ongoing maintenance process rather than a one-time fix.

over the years my website theme has accumulated a bunch of stuff that is not needed anymore and I am sure is slowing it down. From apps that are no longer used to code that was added by a third parties, my theme feels like it has years of baggage of past relationships. How do I clean this up without deleting needed parts of my website. I obviously don’t know code or the backend stuff so I am uneasy about deleting anything.

You can try go get another theme version for your store.

Welcome to the world of legacy code and tech debt. I promise you, this is part of the lifecycle of any website and there is nothing to be afraid of. What you need to do is to not try to do everything at once, get overwhelmed, and throw your hands up in the air. Think of it like pruning a bonzai tree. You don’t trim off everything at once, you take a snip here, take a snip there, and you slowly work your way down to a suitable compromise.

What we’re going to do first is duplicate your production theme. Always keep a clean backup. If you’re not technical, and no one has worked directly on your theme, you may be in luck. You might just be able to delete some apps and update your theme.

You are correct that your old apps might be slowing down your site, so go into your admin panel and determine which ones you actually need, the mission critical apps that keep the lights on. Keep those ones, but make a list of all the others and go through them one at a time. If there are apps you don’t need anymore, by all means deactivate them. If you’re worried about negative repercussions, just do it slowly. Deactivate it and give it a week or so and monitor your web performance report available in your dashboard along with your other store dashboards. If you messed up, you should quickly be able to see it and restore it.

Every major website in the world is in the process of pruning their website of legacy code and tech debt. It is a never ending process, and isn’t something to be afraid of. As long as you work carefully and take your time, you should be able to make improvements.
