### Getting Drupal 8 field values in Twig

Image path: `{{ file_url(content.field_name['#items'].entity.uri.value) }}`

Image title text: `{{ node.field_name.title }}`

Entity Reference path: `{{ content.field_tags[0]['#url'] }}`

### Check if field is filled

To answer my own question, this is possible using the email registration module.

install dev version
apply patch from here
go to /admin/config/people/accounts and check the checkbox: Allow log in with email address or username.
go to /admin/commerce/config/checkout-flows and replace the default login with the login provided by this module
Optionally, the patch from this issue will allow for the username to be entered on registration.

Open up your PHPMyAdmin
Find semaphore table
Delete cron row

Turn on cron logging
See which cron stuck

1. go to WHM, find MultiPHP INI Editor, find php 7.2, ensure allow_url_fopen is Enabled
2. increase ram
3. download composer

4. Run locally php composer.phar require drush/drush:8.x
5. upload the composer.json and composer.lock files
5. Run remotely php composer.phar install

ZIP – Cross Platform
First up is ZIP one of the most commonly used compression techniques used across all platforms

To compress

zip -r archive_name.zip folder_to_compress
To extract

unzip archive_name.zip
If you want to make a zip without those invisible Mac resource files such as “_MACOSX” or “._Filename” and .ds store files, use the “-X” option in the command so:

Following Steps will make working with External JavaScript libraries in Drupal 8 absolutely clear (including how to conditionally load it in specific pages):

Step 1: Place the JavaScript file in your theme or module inside a folder called js. After this step your folder structure must look like :

my-theme/js/my-script.js
Step 2: If your theme already has a my-theme.libraries.yml file open it, if not create it.

In Drupal 8 Libraries are simply collections of CSS or JS files bundled together under a uniquely identified library name.
