Smart Git Sync

Smart Git Sync

Obsidian plugin that keeps your vault in sync with a Git remote. Every save triggers a debounced commit + push. Remote changes are pulled automatically on a configurable interval and can also be triggered on-demand via a local webhook.

Features

• Auto-sync — commit and push after every save (debounced)
• Conflict-safe push — git pull --rebase runs before every push so remote changes are incorporated automatically
• Pull interval — periodically pulls remote changes in the background
• Webhook trigger — exposes a local HTTP endpoint so CI/CD jobs can trigger a pull the moment someone pushes
• Action menu — click the ribbon icon to get a quick-action menu (sync, pull, pause, toggle)
• Pause — suspend sync for 30 min / 1 h / 2 h without disabling it

Requirements

• Desktop only (uses git CLI and the local filesystem)
• git must be in $PATH

Installation

1. Copy main.js and manifest.json into .obsidian/plugins/lkmavi-smart-git-sync/
2. Enable the plugin in Settings → Community plugins

First-time setup

If your vault is not yet a git repository:

1. Open plugin settings → Repository setup → click git init
2. Go to .gitignore section, configure the toggles, and click Generate .gitignore
3. Create an empty repo on GitHub (no README, no license)
4. Paste the clone URL into Set remote origin → click Set remote
5. Run an initial push from a terminal:

   git add . && git commit -m "init" && git push -u origin main
   

6. Enable Auto-sync — the plugin takes over from here

Tip: keep "Ignore .obsidian/" on if you don't want to sync Obsidian settings across devices; turn it off if you do.

Settings

How sync works

file saved
  └─ debounce (default 30 s)
       └─ git add .
            └─ git diff --cached  (skip if nothing staged)
                 └─ git commit -m "auto: sync <timestamp>"
                      └─ git pull --rebase origin <branch>   ← absorbs remote changes
                           └─ git push origin <branch>

If pull --rebase hits a real conflict (same lines edited by two people), the sync fails and a Notice is shown. Resolve the conflict manually in a terminal, then use Sync now from the ribbon menu.

Pull interval

On every tick the plugin runs git fetch origin <branch> to update the remote ref, then compares HEAD vs origin/<branch>. A pull only happens when the commits differ — if already up to date, nothing happens and no notice is shown. The fetch + pull is skipped if a sync is already in progress or sync is paused.

Webhook

The plugin can start a local HTTP server:

POST http://127.0.0.1:<port>/sync
Authorization: Bearer <secret>   ← only if secret is set

A 202 ok response is returned immediately; the pull runs in the background.

Exposing to GitHub Actions

The webhook binds to 127.0.0.1, so it is not reachable from the internet by default. Use a tunnel to expose it:

Option A — Tailscale (recommended for personal vaults)

The plugin can detect your Tailscale IP automatically:

1. Install Tailscale on your machine.
2. Set a Webhook port in plugin settings.
3. Click Detect — the plugin runs tailscale ip -4 and fills in the full webhook URL.
4. Click Copy URL and save it as VAULT_WEBHOOK_URL in your repo secrets.
5. Click Copy GitHub Actions step to get a ready-to-paste workflow step.

Full workflow example:

# .github/workflows/notify-vault.yml
on:
  push:
    branches: [main]

jobs:
  notify:
    runs-on: ubuntu-latest
    steps:
      - uses: tailscale/github-action@v2
        with:
          authkey: ${{ secrets.TAILSCALE_AUTHKEY }}

      - name: Notify Smart Git Sync
        run: |
          curl -fsS -X POST \
            -H "Authorization: Bearer ${{ secrets.VAULT_WEBHOOK_SECRET }}" \
            ${{ secrets.VAULT_WEBHOOK_URL }}

Option B — cloudflared tunnel

cloudflared tunnel --url http://127.0.0.1:<port>

Copy the generated *.trycloudflare.com URL, add it as VAULT_WEBHOOK_URL in your repo secrets, then:

- name: Notify Smart Git Sync
  run: |
    curl -fsS -X POST \
      -H "Authorization: Bearer ${{ secrets.VAULT_WEBHOOK_SECRET }}" \
      ${{ secrets.VAULT_WEBHOOK_URL }}/sync

Option C — ngrok

ngrok http 127.0.0.1:<port>

Same as cloudflared: copy the forwarding URL and use it in your workflow.

Local scripts

If you just want to trigger a pull from a script on the same machine:

curl -X POST http://127.0.0.1:<port>/sync

No tunnel needed.

Ribbon menu actions

Click the cloud icon in the left ribbon to open the action menu:

• Sync now — commit & push immediately
• Pull — pull latest from remote
• Enable / Disable auto-sync — toggle without going to settings
• Pause 30 min / 1 h / 2 h — suspend auto-sync temporarily
• Resume — shown instead of pause options when sync is paused
