I see many people use https://www.drupal.org/project/eck  module when they want to create new entites in drupal 8. But there is a problem with that. By default ECK module in UI doesn't create base fields, you can create bundles and then add fields to them.

In order to generate authenticated requests using curl we can use the session cookie from a session in our browser. How to find that? Sign in to your site in your browser. Then find the cookie that starts with either SESS, or SSESS followed by a random string.

For multi-currency in drupal 7 commerce we had it all running out of the box with drupal multicurrency modul. You had price fields per currency and rules that would solve that. There is no out of the box solution like that yet, but this module is pretty close to it.

We talked here https://www.drupaldump.com/xdebug-and-docker4drupal-mac how to setup docker and xdebug, most people use phpstorm, but you could also use sublime editor with it, install with package commander xdebug client and then you will need to do some additional manual setup
 

Some times you dont want to add something to .gitignore, while it would be nice that there is some .gitignore-local version by default, there is not, so you need to find a different way to do this, the way to do is this.  Go to .git/info/exclude file and edit it like regular .gitignore file, add files/folders you want to ignore.

To have xdebug working, you need to have this in your docker config for PHP.

      PHP_XDEBUG: 1
      PHP_XDEBUG_DEFAULT_ENABLE: 1
      PHP_XDEBUG_REMOTE_CONNECT_BACK: 0
      PHP_XDEBUG_REMOTE_HOST: 10.254.254.254 # macOS, Docker < 18.03

Also it is often noted that this should also be run

After few examples pointed before, how to make links and urls,
https://www.drupaldump.com/making-url-anchorfragment-and-making-url-que…
https://www.drupaldump.com/some-ways-make-links-drupal-8

$options = ['fragment' => 'feedback'];
$url = Url::fromRoute('entity.node.canonical', ['node' => 22], $options);

$options = ['query' => ['animal' => 'dog', 'color' => 'black']];
$url = Url::fromRoute('entity.node.canonical', ['node' => 42], $options);

So first would give you  this result 

// Link to an internal path defined by a route.
$link = Link::createFromRoute('This is some link', 'entity.node.canonical', ['node' => 22])

// Link to an external URI.
$link = Link::fromTextAndUrl('This is a link', Url::fromUri('https://example.com'));

// Get output as a render array.
$link->toRenderable();

// Get output as a string.
$link->toString();

// From a route.
$url = Url::fromRoute('contact.site_page');
// From a URI.
$url = Url::fromUri('https://example.com');
// From route with additional parameters.
$url = Url::fromRoute('entity.node.canonical', ['node' => 22]);
