LiveSync Bridge

What is this?

This is a custom replicator between Self-hosted LiveSync remote vaults and storage. The Unified Version of filesystem-livesync and livesync-classroom.

A Vault or storage can be synchronised with vaults or storage. You can even combine them. Of course, different passphrases for each vault could be used. And, you can synchronize documents under the specified folder on the vault, to another vault's specified one.

Of course, it is multi-directional!

How to use

Prerequisites

• Deno is required.

Simply run

1. Clone the GitHub Repository

git clone --recursive https://github.com/vrtmrz/livesync-bridge

2. Open the config file dat/config.sample.json, edit and save to dat/config.json. (You do not have to worry, the sample is in the following section).
3. Simply run like this.

$ deno run -A main.ts

Note: If you want to scan all storage and databases from the beginning, please run with --reset.

Docker Instructions

1. Clone the GitHub Repository

git clone https://github.com/vrtmrz/livesync-bridge

2. Open the config file dat/config.sample.json, edit and save to dat/config.json. (The storage folder has to start with "data/" to be in the volume)

3. Simply run like this.

   docker compose up -d

Configuration

The configuration file consists of the following structure.

{
  "peers": [
    {
      "type": "couchdb", // Type should be `couchdb or storage`
      "name": "test1", // Should be unique
      "group": "main", // we can omit this.
      "database": "test",
      "username": "admin",
      "password": "password",
      "url": "http://localhost:5984",
      "customChunkSize": 100,
      "minimumChunkSize": 20,
      "passphrase": "passphrase", // E2EE passphrase, if you do not enabled, leave it blank.
      "obfuscatePassphrase": "passphrase", // Path obfuscation passphrase, if you do not enabled, leave it blank. if enabled, set the same value of passphrase.
      "baseDir": "blog/", // Sharing folder

    },
    {
      "type": "couchdb",
      "name": "test2", // We can even synchronise the same databases as long as they have different names in here.
      "group": "main", // we can omit this.

      "processor": { // The processor configuration. You can omit this.
        "cmd": "script/test.sh",  // The programme which run at file modification or deletion.
        "args": [ "$filename", "$mode" ] 
        // The modified file is set to $filename. The mode is set to `deleted` or `modified`. 
        // $filename and $mode have been set also in environment variables.
      },
      "scanOfflineChanges": true,
      "useChokidar":false, // We are using `Deno.watch` now, if you have trouble in Linux, please enable this.
    }
  ]
}

Realistic example

Cornbread's every document under "shared" is synchronized with the top of the shared vault:

Vanilla's every document under "kyouyuu" is synchronized with the top of the shared vault:

Totally, all files are synchronized like this:

... with the configuration below:

{
  "peers": [
    {
      "type": "couchdb", // Type should be `couchdb or storage`
      "name": "cornbread", // Should be unique
      "url": "http://localhost:5984",
      "database": "classroom_cornbread",
      "username": "cornbread",
      "password": "tackle",
      "passphrase": "glucose", // E2EE passphrase, if you do not enabled, leave it blank.
      "obfuscatePassphrase": "glucose", // Path obfuscation passphrase, if you do not enabled, leave it blank. if enabled, set the same value of passphrase.
      "customChunkSize": 100,
      "minimumChunkSize": 20,
      "baseDir": "shared/" // Sharing folder
    },
    {
      "type": "couchdb", // Type should be `couchdb or storage`
      "name": "shared", // Should be unique
      "url": "http://localhost:5984",
      "database": "classroom_shared",
      "username": "common_user",
      "password": "resu_nommoc",
      "passphrase": "cocoa", // E2EE passphrase, if you do not enabled, leave it blank.
      "obfuscatePassphrase": "cocoa", // Path obfuscation passphrase, if you do not enabled, leave it blank. if enabled, set the same value of passphrase.
      "customChunkSize": 100,
      "minimumChunkSize": 20,
      "baseDir": "" // Sharing folder
    },
    {
      "type": "couchdb",
      "name": "vanilla", // We can even synchronise the same databases as long as they have different names in here.
      "url": "http://localhost:5984",
      "database": "classroom_vanilla",
      "username": "vanilla",
      "password": "liberty",
      "passphrase": "smock",
      "obfuscatePassphrase": "smock",
      "customChunkSize": 100,
      "minimumChunkSize": 20,

    },
    {

      "name": "storage-test1",
      "baseDir": "./vault/" // The folder which have been synchronised.
    }
