How can I remove unused code after uninstalling apps?

[TattooKits]

I found that after uninstalling the apps, the page will have a lot of unused code, affecting the speed of the page. Is there any apps that can clear all unused code of the website?

[Perennial]

Unfortunately, there is no app in Shopify that does this work of clearing out the code.

However, we can certainly help you in removing the unused code from uninstalled app if you can provide more details to it.

Looking forward to hearing from you.

Thanks & Regards,

i have the same problem causing major problem in my store. why are these apps not required to remove all there code when the app is deleted. people should be warned about this before adding any apps. is there any tool out there to identify the location of unused code. i can delete the code if i know what file its in and how to identify the code.

Sorry but there are no tools available for identifying the unused code after deleting the app.

Can you help me out with this same problem?

We went through the Shopify app review process about 2 months ago and Shopify takes this issue quite seriously now.

They ask that app developers have a way to automatically remove any inputted code on the store. For example, we have a button on our ‘setup’ page. It might be worth re-installing said apps, just to make sure they don’t have an equivalent.

Cheers,

Oli

Hi, Can someone help me learn how to remove unused code? Unused JavaScript causes 2.7 sec delay on my website - I am sure it’s caused from uninstalled apps. I ran speed test and after uninstalling some apps that I wanted to try but didn’t like, it made my websit mobile speed score 34, when it was around 65. Thanks!

[OliUK]

Hi @Foresterbags ,

If you open your store on Google Chrome and then hold control and click the page, then select ‘inspect’ from the box.

Then click on the ‘Network’ tab on the top of the newly opened side panel. You should be able to see a waterfall diagram of your pages load time, maybe list out any slowly loading items (before the red line) especially if they contain the name of prior apps.

Is it your product pages that are loading slowly? or the catalogue/collection pages? If you copy and paste the code into this thread, I’m happy to have a quick look at it and see if there’s anything obvious we could take out.

Cheers,

Oli

Hi Amit,

The message which is pretty much repeated throughout your log is a hot topic at the moment. Internet browsers are putting in stricter rules regarding cookies. Shopify knows about this and I think it was even talked about at the latest Shopify Unite web conference.

Basically app developers have to push an update out to fix it. I’m suprised PayPal haven’t already done this, but maybe there’s something else going on that I’m not privy to.

To summarise, that error won’t slow your site down, but it will stop certain apps functioning in future Chrome versions.

Cheers,

Oli

Hi Jack,

It seems like 'Ali Reviews’s is the app mostly slowing your product pages down.

Hi @brunashaqiraj

I don’t think your sites that slow to be honest mate. The top loading times other than Shopify stuff looks like Google leads and there’s also a failed request to this URL: https://unpkg.com/eventemitter3@4.0.4/umd/eventemitter3.min.js to get come javascript, this might be important for elsewhere on your site though.

Hey @lsmall ,

I had a quick look at your site. There was a couple of errors you could look into, but sometimes these errors are just ungracefully managed results of fully operational apps.

The two that came up are: helpfulcrowd.com and getshowgun.com. If you’re using both of these apps, then I wouldn’t necessarily worry about it. Your product page load speed on my Mac is 1.58secs which seems pretty reasonable.

Cheers,

Oli
