View access per node

Introduction

View Access Per Node (vapn) is a very simple access control module with
relation to viewing content on a per-node basis, the initial idea is a porting of the D7 module "View Permissions Per Node" https://www.drupal.org/project/vppn but more features/integrations are planned for this project.

This module only deals with viewing nodes, it does not affect other ops (eg. create/update/delete).

There are a lot of access control modules, many of them are compared here
https://www.drupal.org/node/270000

This module only uses hook_node_access so it should play fairly well with other access control modules.

Installation

- Enable the module (https://www.drupal.org/docs/8/extending-drupal-8/installing-drupal-8-mod...) as usual,
- Set permissions for users that can use and administer vapn.

Configuration

- Navigate to admin/config/vapn/vapnconfig and select the content types,
- Create or edit a node with one of the types selected above,
- There will be a new vertical tab named "View Access per node",
- Select the roles that will have view access to this node.

Notes

- Roles with the bypass node access permission will not be listed,
- Selecting no roles will skip using this module for access control,
- Selecting even one role will enable this module for access control, and deny
access to any users without one of the selected roles.

Version 3
- It now switched to use entity/field api to handle the permissions https://www.drupal.org/project/vapn/issues/3394494.
- In previous version, if you don't specify a role in your node, by default it will show it for all users. In version 3, it will now only show it to administrator.
