This is a Work in progress

A To compile

just run yarn install and then yarn dev or yarn prod

B To install test within laravel

for now :

1. add this to a laravel project with composer, you can use this as a local project, in your composer.json :

       "repositories": {
           "kwaadpepper/laravel-omen": {
               "type": "path",
               "url": "pathTo/laravel-omen-git-pull-from-github.git",
               "options": {
                   "symlink": true
               }
           }
       },
   

2. then composer require kwaadpepper/laravel-omen

3. navigate to vendor/kwaadpepper/laravel-omen and run yarn prod, then access the url /omenfilemanager within your laravel project

You can override --tag=config, --tag=assets, --tag=views, --tag=lang :

php artisan vendor:publish --provider="Kwaadpepper\Omen\Providers\OmenServiceProvider" --tag=assets

If you are using local storage and dont need to set files to private you can use this

sudo php artisan omen:link

• About CSRF

  https://cheatsheetseries.owasp.org/cheatsheets/Cross-Site_Request_Forgery_Prevention_Cheat_Sheet.html

  Use is made of the Laravel built-in CSRF system token. In addition, an Ajax CSRF token is used for every request (even if only write operation should require it).

• About CSP policies

  https://cheatsheetseries.owasp.org/cheatsheets/Content_Security_Policy_Cheat_Sheet.html

  This lib uses a CSP strategy on all its assets requirements (CSS, JS) using nonce. This is configurable through the config file ('omen.csp')

• About X-Frame-Options

  X-Frame-Options is sent to the client to prevent click jacking (iframe embed) https://www.keycdn.com/blog/x-frame-options false => X-Frame-Options: deny true => X-Frame-Options: sameorigin

• About X-Content-Type-Options

  Used againts mime sniffing to prevent cross site scripting. Thus, any file served will be treated with the type declared by the server https://www.keycdn.com/support/x-content-type-options This is always set to no sniff, and is not configurable

• About Referrer-Policy

  https://openweb.eu.org/articles/referrer-policy

  No tracking is needed by Omen, and it dont want to be tracked also BTW. So Referrer-Policy is set to no-referrer. This is not configurable since there is no need to.

• About Feature-Policy

  https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Feature-Policy

  All enabled features are set to self, since Omen provides all the libs. No CDN is used for security purpose. Alose to enable the use on offlines networks. Only down side of this is Google Api to display docs wont be available. Only use is made of:

  • autoplay for video

  • fullscreen for multiple files type view

  • layout-animations for Omen interface to display

  • legacy-image-formats

    This policy controls the ability of the document to render images in legacy image formats. These are defined as any format other than JPEG, PNG, GIF, WEBP, or SVG. TODO Inspect Display possibilities on images formats

  • midi

    TODO can midi file be played ?

  • navigation-override

    https://github.com/w3c/webappsec-feature-policy/issues/175

  • oversized-images

  • picture-in-picture for video play

  • sync-xhr For ajax queries

  accelerometer 'none'; ambient-light-sensor 'none'; autoplay 'self'; battery 'none'; camera 'none'; display-capture 'none'; document-domain 'none'; encrypted-media 'none'; execution-while-not-rendered 'none'; execution-while-out-of-viewport 'none'; fullscreen 'self'; geolocation 'none'; gyroscope 'none'; layout-animations 'self'; legacy-image-formats 'self'; magnetometer 'none'; microphone 'none'; midi 'self'; navigation-override 'self'; oversized-images 'self; payment 'none'; picture-in-picture 'self'; publickey-credentials-get 'none'; sync-xhr 'self'; usb 'none'; vr 'none'; wake-lock 'none' xr-spatial-tracking 'none';

• About max upload size

  Because upload is ajax handled yt has to be changed on php.ini or .htaccess, two values needs to be changed: 'upload_max_filesize' and 'post_max_size'

  You can put this in public/.htaccess

  php_value post_max_size 2M
  php_value upload_max_filesize 2M
  

  Because upload is ajax handled, it sends chunks of 2M size. Then if you want to set a limit just change maxUploadSize to something like '3M' or 3145728

• About file names

  File names are always lower cased on created, this is for Windows compatibility since windows file names are not case sensible which means windows will threat 'file.pdf' 'File.pdf' as the same file whereas on a Unix based it will not.

• About unit tests

  Include unit tests using Orchestra, just run phpunit from project folder after composer install

• About Tinymce

  To use with tinymce you will have to set useXFrameOptions to true, in order to allow the display omen in a iframe

  Here is an example, you must set external_filemanager_path with directive @omenPath() and register the omen plugin external_plugins with { "omen": "@tinymcePluginPath()" }

  tinymce.init({
      selector: "#tinymce"
      , plugins: [
          "advlist autolink link image lists charmap print preview hr anchor pagebreak"
          , "searchreplace wordcount visualblocks visualchars insertdatetime media nonbreaking"
          , "table directionality emoticons paste omen code"
      ]
      , toolbar1: "undo redo | bold italic underline | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | styleselect"
      , toolbar2: "| omen | link unlink anchor | image media | forecolor backcolor  | print preview code "
      , image_advtab: true
      , external_filemanager_path: "@omenPath()"
      , external_plugins: {
          "omen": "@tinymcePluginPath()"
      }
  });
  

• About CKEditor

  To use with CKEditor no need for iframe autorization. However you will have to set it as the default filemanager. You will have to set filebrowserImageBrowseUrl with this directive @omenPath(type=image&editor=ckeditor) and eventually filebrowserBrowseUrl with this directive @omenPath(editor=ckeditor)

  CKEDITOR.editorConfig = function(config) {
      config.language = "en";
      config.uiColor = "#F7B42C";
      config.height = 300;
      config.toolbarCanCollapse = true;
      config.extraPlugins = "omen";
      config.filebrowserImageBrowseUrl = "@omenPath(type=image&editor=ckeditor)";
      config.filebrowserBrowseUrl = "@omenPath(editor=ckeditor)";
  };
  CKEDITOR.replace("ckeditor");
  

Some thing good to know is that it is possible to restrict file types to be used with url directive: eg: add url GET parameter type=image to use image only or type=archives

• About standalone button

  You can use a standalone button to call the file manager if you want to.

  First insert the plugin (requires jquery) in you html file

  <html>
      ...
      <head>
          ...
          @omenButton()
      </head>
      ...
  </html>
  

  Create an input on your page

  <div class="input-group">
      <span class="input-group-btn">
          <a id="omenButton" data-input="textInput" class="btn btn-primary">
          <i class="fa fa-picture-o"></i> Open file </a>
      </span>
      <input id="textInput" class="form-control" type="text" name="filepath">
  </div>
  

  Call the plugin on your button

  $(document).ready(function() {
      $('#omenButton').omenButton('image');
  });
  

  omenButton function accepts file, image, audio, video, archive in case you want to restrict file types

  You may want to look at resources/js/plugins/omen.Button.jquery.plugin.min.js if you want to call with js the file manager via popup
