Project Zxcvbn The Ruby Toolbox

Loading... Loading... Menu This document describes the file and directory organization of the zxcvbn-js gem. It covers the layout of the Ruby source code, JavaScript assets, test infrastructure, and distribution files. For information about specific build tasks and development workflows, see Build and Development Tools. For details about gem packaging and distribution, see Gem Distribution. The zxcvbn-js gem follows a standard Ruby gem structure with specific directories for the Ruby wrapper code, JavaScript assets, and testing infrastructure.

Sources: lib/zxcvbn.rb1-18 lib/zxcvbn/tester.rb1-18 lib/zxcvbn/version.rb1-4 zxcvbn-js.gemspec1-23 Rakefile1-18 The root directory contains the standard gem distribution and configuration files: Sources: zxcvbn-js.gemspec1-23 Rakefile1-18 README.md1-52 LICENSE1-23 lib/ )The lib/ directory contains all Ruby source code and follows the standard convention for loadable library files.

lib/zxcvbn.rb The top-level module file serves as the public API facade: The file structure at lib/zxcvbn.rb1-18 shows: - Lines 1-3: Required dependencies ( version ,tester ) - Lines 5-6: Zxcvbn module withextend self for module methods - Lines 13-16: test() method that creates aTester instance per call Sources: lib/zxcvbn.rb1-18 lib/zxcvbn/ The lib/zxcvbn/ subdirectory contains the implementation classes: lib/zxcvbn/tester.rb The core implementation class that bridges Ruby to JavaScript: - Line 2: Requires execjs gem for JavaScript execution - Line 5: Defines DATA_PATH constant pointing todata/zxcvbn.js - Lines 7-10: initialize method loads and compiles the JavaScript file viaExecJS.compile() - Lines 12-15: test method executes the JavaScriptzxcvbn() function and wraps results inOpenStruct Sources: lib/zxcvbn/tester.rb1-18 lib/zxcvbn/version.rb Contains the gem version constant: - Line 2: VERSION = "4.4.3" constant used by gemspec Sources: lib/zxcvbn/version.rb1-4 data/ )The data/ directory contains the production JavaScript asset: data/zxcvbn.js This is the complete zxcvbn.js library from Dropbox, approximately 20MB in size due to embedded dictionary data: The file structure at data/zxcvbn.js1-7 shows: - Line 1: UMD (Universal Module Definition) wrapper for cross-environment compatibility - Line 2: Adjacency graph data for keyboard pattern detection (qwerty, dvorak, keypad, mac_keypad) - Lines 4-7: Module definitions including frequency lists (passwords, surnames, names, wikipedia terms) This file is loaded by Zxcvbn::Tester at lib/zxcvbn/tester.rb5-9 and contains the entire password strength algorithm implementation.

While the actual test files are not fully shown in the provided files, the architecture diagram indicates the following structure: The test infrastructure includes: spec/spec_helper.rb : RSpec configuration that loads the gem and test helpersspec/zxcvbn_spec.rb : Main test suite that verifies Ruby wrapper behaviorspec/support/js_helpers.rb :JsHelpers module providing direct JavaScript execution capabilities via V8 for comparing Ruby wrapper output against direct JavaScript executionspec/support/js_source/ : JavaScript test assets and CoffeeScript sources The Rakefile at Rakefile15-18 shows a compile_coffeescript task that compiles CoffeeScript sources in spec/support/js_source/ into JavaScript.

Sources: Rakefile7-8 Rakefile15-18 The following diagram shows how files depend on and load each other: Sources: lib/zxcvbn.rb1-3 lib/zxcvbn/tester.rb2 lib/zxcvbn/tester.rb5 zxcvbn-js.gemspec2 zxcvbn-js.gemspec16 Rakefile6-8 The codebase follows several organizational principles: Only three Ruby files contain implementation logic: lib/zxcvbn.rb : 18 lines - convenience APIlib/zxcvbn/tester.rb : 18 lines - ExecJS bridgelib/zxcvbn/version.rb : 4 lines - version constant This minimal footprint reflects the design decision to wrap the JavaScript implementation rather than reimplementing the algorithm in Ruby.

The project follows Ruby gem conventions: - Loadable code in lib/ - Non-code assets in data/ - Tests in spec/ - Distribution files at root The Zxcvbn::Tester class uses a relative path to locate the JavaScript asset at lib/zxcvbn/tester.rb5: This path resolves from lib/zxcvbn/tester.rb up three levels to the gem root, then into data/zxcvbn.js , ensuring the asset is found regardless of where the gem is installed.

Sources: lib/zxcvbn/tester.rb5 The gemspec at zxcvbn-js.gemspec11 uses git to determine which files to include in the gem package: This automatically includes: - All files tracked by git - Files in lib/ ,data/ , andspec/ - Root-level files like README.md and LICENSE The gemspec explicitly sets gem.require_paths = ["lib"] at zxcvbn-js.gemspec15 so that require 'zxcvbn' loads lib/zxcvbn.rb . Sources: zxcvbn-js.gemspec11 zxcvbn-js.gemspec15 This structure ensures that the gem has minimal Ruby code overhead while providing full access to the JavaScript implementation's functionality through the ExecJS bridge.
