bare-bundle

Application bundle format for JavaScript, inspired by https://github.com/electron/asar.

npm i bare-bundle

Format

[#!hashbang]
<header length><header><...files>

The header length is an integer literal denoting the total length of the header. The header itself is a JSON string literal of header length bytes and has the following format:

{
  "version": 0,
  "id": null | "<string>",
  "main": null | "<url>",
  "imports": {
    "<from>": "<to>"
  },
  "resolutions": {
    "<url>": "<imports>"
  },
  "addons": ["<url>"],
  "assets": ["<url>"],
  "files": {
    "<url>": {
      "offset": number,
      "length": number,
      "mode": number
    }
  }
}

For each <url> in files, offset provides the byte offset to the file after the header and length provides the byte length of the file.

The bundle may optionally be prefixed with a hashbang, #!, for use with script interpreters. The hashbang is ignored during parsing.
