Drupal 8.x

I moved my site files to my home PC to get around the php memory limit of my provider. But when I put the Drupal 8.8.0 core and vencor directories in place, and run

composer update --no-dev --with-dependencies

The first thing that happens is that the core directory is removed, and I get many errors.

What is wrong?

Hi all, my name is a Alan and I would describe myself as a total hobbyist with regards to Drupal. (a slightly advanced novice at best) and a 100% lover of the platform and the work done by the community.

I have an idea for a project based round community input and moderation.

I have been tinkering with workflows and have installed content moderation and I have it all working nicely.

However, and there is always a however...

I have a field in my article type that is shared by the articles and all users in their profile (a taxonomy term).

While installing drupal 8 in local environment, I did not provide any DB details, so it created default settings.php and automatically created DB also. 

$databases['default']['default'] = array(
  'database' => "db",
  'username' => "db",
  'password' => "db",
  'host' => $host,
  'driver' => "mysql",
  'port' => $port,
  'prefix' => "",
);

I'm trying to become more comfortable with AJAX outside of forms and have checked some helpful pages to get me to this point. In D7, I built a custom module that loaded up two HTML tables, one with a few hundred rows and a second with a few thousand rows. The latter was wrapped in a div that was hidden. That meant the user had to wait for both tables to finish before the page loads. 

I created a module to increase the filed length to 1024 from 128 since my view filter fields are pretty lengthy. Below is the code snippet inside .module file. But this code is not working. Any help? Should this module be linked in the .THEME file?

I have a filter section created with views. One of the filter field is zipcode. When I enter a zipcode '20014' I would like to see the google map under the zip code field with pins of shops around that zipcode. Is this possible to be done in Drupal views? Can any 3rd party module help with this?
