So I have a laravel / react application that I am developing. The javascript is compiled with laravel mix.

In the company I work for we have an external package that we use in all of our products for brand consistency. This package essentially is a bunch of components that we can re-use everywhere very easily.

Recently I updated the package to have a new component and also updating functionality of some existing components. I finished those changes and published the new version of the package and then in the main project I updated the package version in the package.json so that I could use all these new features / component I just added. After updating the package version number in package.json I ran npm install and then npx mix watch to work on integrating these new features into my application and everything went well and was working fine.

Once my work was done and tested by myself I went to push the changes to staging for review but the changes / features I had added to the external package didn't seem to be working properly.

Long story short I came to realise that locally, when I run npx mix watch and view the site that way, everything works fine however, when I run npx mix --production (which is also what is being run on the server staging environment when it gets built) I have the same problem where the features I added to the package are not working.

I have no idea what is causing this and why everything is working fine with npx run watch and why it isnt working with npx mix --production and I dont really know where to look to debug?

I have tried looking at the console, I have looked at the terminal running --verbose with both commands to see if there is any output that might be useful but I can't identify anything wrong. I have tried making changes to the external package for the sake of just publishing a new version and just hoping that might trigger something. I have tried clearing the cache of npm, browser cache, everywhere I can think there may be cache basically.

I'm just at a loss for where to look and what might be causing this...

Please let me know if you need any more info. Any help would be greatly appreciated.

Thanks.
