Rev Obsidian Sync

Reverse engineered obsidian sync server (NOT OFFICIAL)

Warning

The main branch is the development branch. For stable usage, use the latest release.

Note

If you have the time and energy, feel free to help out with PRs or suggestions.

Features

• End to end encryption
• Live sync (across devices)
• File history/recovery/snapshots

• Vault sharing

Experimental

These features are not in the latest release but in the main branch. They might not be fully tested and are probably unstable.

• Obsidian publish

To do

• Fix bugs
• Publish

Setup

• git clone https://github.com/acheong08/obsidian-sync
• cd obsidian-sync
• export HOST=<YOUR DOMAIN NAME> - Not necessary when running on localhost
• go run cmd/obsidian-sync/main.go
• Use nginx or cloudflare to proxy & handle TLS/SSL

HTTPS should be required. I use certbot or Cloudflare. By default, the sync uses wss unless you're operating on localhost or 127.0.0.1 which breaks if you don't have TLS/SSL

HTTPS is not required.

When you're done, configure the plugin

Nginx configuration

map $http_upgrade $connection_upgrade {
        default upgrade;
        '' close;
}
server {
	listen 80 default_server;
	listen [::]:80 default_server;
	location / {
		proxy_http_version 1.1;
            	proxy_set_header Upgrade $http_upgrade;
            	proxy_set_header Connection $connection_upgrade;
           	proxy_set_header Host $host;
		proxy_pass http://127.0.0.1:3000/;
	}
	server_name _;
}
