Just put your whole Obsidian vault or markdown folder/file structure in your web directory. The page builds itself.

Its an open source alternative to obisidian publish.

Read more about Perlite and staging tips on my blog post: Perlite on Secure77.

Install

Just put the content of the perlite directory in your web root directory, your notes should resident as a subfolder of perlite.

For Docker just check the DOCKER readme.

Requirements

  • Web server, tested with coverage
  • Php-fpm, tested with coverage
  • Php module mb_strings for the parsedown (apt install php-mbstring)

Required Obsidian Options

  • In the options Files & Links you need to set the New link format to Relative path to file Link Options

Graph

  • For the Graph you need to install the plugin Metadata Extractor, you can also do this via the build in Community Plugin Browser
  • Make sure to turn on the plugin
  • In the settings, set the path of the metadata.json to your local vault root folder (like C:\Users\John\MyNotes\metadata.json, when your vault is MyNotes). if you transfer your vault later to a webserver, make sure the metadata.json will be transferred too.
  • Also dont forget to set a timer how often the file should be written or just enable Write JSON files automatically when Obsidian launches

Plugin Options

Hide Folders and Files

  • If you want to exclude specific folders, e.g. your attachment folder you can set the HIDE_FOLDERS variable or replace $hideFolders = getenv('HIDE_FOLDERS'); in the helper.php with something like this $hideFolders = 'attachments';
  • Folders and files starting with a "." (dot) are exclude by default Folders Options

Advanced Options and Infos

Header, Logo and Start Page

you can adjust them via the index.php

  • The About opens a .md file in a modal window (.about.md per default), you can change this in the helper.php $about variable
  • The Logo, Blog and so on are nested in the index.php (line 47 e.g. for the link to the Blog)
  • The Startpage is set to README.md, you can change this in the helper.php $index variable and in the perlite.js homeFile variable

Graph

The Graph is implemented with vis.js, so there are many options you can play on with, you can adjust them via the options object in the perlite.js

Root Dir

  • Without setting a NOTES_PATH enviroment variable, Perlite takes the perlite directory as root folder, this means, you need to copy your content of the vault folder into the perlite directory (including metadata.json if you want a graph).
  • If you want to change or specify the root directory of your vault, you can do this by changing the variable $rootDir in the helper.php or by setting the NOTES_PATH as php variable.
  • You can see an example of this in the Release, just uncomment the //$rootDir = 'Demo'; in the helper.php and see how the build changes, also notice the two metadata.json, one in the perlite folder and one in the Demo folder, depending on your rootDir either the one in perlite or the one in Demo will be used.

Open File in Obsidian

  • Add the cookie vaultName with value of your Vault Name to display an edit button next to the fullscreen button. The button opens the current document in your Obsidian vault. Make sure to set the HttpOnly attribute to false. Otherwise, client-side script access for the cookie is blocked.

Python Parser

  • There is a pythonParser.py to genereate the vis.js JSON structure out of the metadata.json. This script is not beeing used anymore but I will let it here.

Security

  • The Safemode from Parsedown is active, but I would not recommend to allow untrusted user input.
  • You should prevent that the .md files are direct accessible via the browser (only the php engine need access to it) or at least make sure that the md files will be downloaded and not be rendered by browser
  • You should prevent that the metadata.json file is direct accessible via the browser (only the php engine need access to it). The extracted metadata.json contains the whole obsidian structure, so this file could be sensitive if you plan to exclude some files or folders from Perlite. However, the parsing is done by the php engine and it checks for every path if the file really exists in the provided vault, so files you excluded from the vault will also not be visible in the graph, but they are still present in the metadata.json. This is why you should prevent access to it.

Why Perlite?

Wiki: Perlite is an amorphous volcanic glass ... typically formed by the hydration of obsidian.
