braidfs

Sync Braid URLs as files on disk.

Like Dropbox (file sync), plus Google Docs (collaborative editing), all over HTTP.

Installation

Install braidfs globally using npm:

npm install -g braidfs

Usage

To start the braidfs server:

braidfs serve

To sync a URL:

braidfs sync <url>

When you run braidfs sync <url>, it creates a local file mirroring the content at that URL. The local file path is determined by the URL structure. For example:

• If you sync https://example.com/path/file.txt
• It creates a local file at ~/http/example.com/path/file.txt

To unsync a URL:

braidfs unsync <url>

Accessing the Server

The braidfs server runs on http://localhost:10000 by default and provides the following endpoints:

• /<url>: Synchronizes the specified URL: creates a local file, and provides a Braid-HTTP interface
• /.braidfs/config: Displays the current configuration
• /.braidfs/errors: Shows the error log

Accessing a URL through the proxy (e.g., http://localhost:10000/https://example.com/file.txt) will automatically add it to the set of synced URLs, similar to using braidfs sync <url>.

Configuration

braidfs looks for a configuration file at ~/http/.braidfs/config. You can set the following options:

• port: The port number for the proxy server (default: 10000)
• sync: An object where the keys are URLs to sync, and the values are simply "true"
• domains: An object for setting domain-specific configurations, including authentication headers

Example config.json:

{
  "port": 10000,
  "sync": {
    "https://example.com/document1.txt": true,
    "https://example.com/document2.txt": true
  },
  "domains": {
    "example.com": {
      "auth_headers": {
        "Cookie": "secret_pass"
      }
    }
  }
}

The domains configuration allows you to set authentication headers for specific domains. In the example above, any requests to example.com will include the specified Cookie header.

Security

braidfs is designed to run locally and only accepts connections from localhost (127.0.0.1 or ::1) for security reasons. The domains configuration enables secure communication with servers that require authentication by allowing you to set domain-specific headers.
