Pedro was saying he had a problem with sudden interruption of the root path ...its not kernel so...what they are doing is ...and what he can do is..

gitbook-plugin-hidden 

https://www.npmjs.com/package/gitbook-plugin-hidden

Hide blocks unless authorized with .htpasswd

Hide content based on basic authorization

This plugin is meant to be used on a PHP enabled server.

First you need a .htaccess in your root directory.

# Enable Basic Auth

AuthType Basic

AuthName "SomeDescription"

 

# Point to our password file

AuthUserFile /path/to/.htpasswd

Require valid-user

 

# Redirect all `*.html` to `*.php`

RewriteEngine On

RewriteRule ^(.*)\.html$ $1.php [L]

Then in a .htpasswd file, you can enter username/password pairs. Passwords are hashed using the MD5 algorithm. You can generate a password with

$ htpasswd /path/to/.htpasswd user1

or use this website

Here is an example .htpasswd

user1:$apr1$OS3sZCvx$KRmhPMpZ9bYs4INph8s6w.

user2:$apr1$3Vfr8Z9d$UeKjYDdJK2XFQRUPw7h9T.

You can set the usernames using the plugins configuration in the book.json:

{

  "plugins": ["hidden"],

  "pluginsConfig": {

    "hidden": {

      "usernames": ["user1", "user2"],

      "path": "_book",

      "env": "production"

    }

  }

}

usernames: is an array of authorized users (default: [])

path: is the path to your generated html GitBook (default: _book)

env: NODE_ENV value you want this plugin to be fully executed in. Useful for local development as this plugin breaks functionality of gitbook serve (default: production)

Now in your markdown, you can have hidden blocks:

{% hidden %}

### This will be hidden except for authorized users

{% endhidden %}
