Admin side api: https://github.com/abantecart/abantecart-src/tree/master/public_html/admin/controller/api
Storefront side: https://github.com/abantecart/abantecart-src/tree/master/public_html/storefront/controller/api

Check connection from another program. For example: WorkBench or mysql console client.

You can create extension and replace template:

Bad way - edit this file.

It all depends on what you need. For development, they usually take the root directory of the site and the database outside the container. For operation, only the database is taken out of the container.

Check File Permissions

Marketplace used: https://marketplace.abantecart.com/elastic_search

Describe the architecture in more detail. Show docker and nginx config

what is your server configuration? php version? php libraries list?

You need to check abantecart error log & server error log

You can check installed/removed extensions

You can try last version
We fix some issues in admin template.

You can see network requests in Browser Inspect tool (tab network).
We don't know what is you domain, hosting, network etc.
We can give you only general recomendations.

Looks like slow DB connection/work. Check your DB server. You can enable slow logs. Check CPU/Disk/Memory usage etc.

This is related to the DB, the tag is part of the index, MYSQL sort the data in the index

Yes I have.

Here 2 ways:
1. Import as JS library in template files. See https://vuejs.org/v2/guide/installation.html
2. Build your component and then pack it with webpack (or other tools), and then import it as external script.

Both approaches work and have their pros and cons
