Loading... Loading... Menu This document provides a high-level introduction to the zxcvbn-js gem, a Ruby wrapper for the Dropbox zxcvbn.js password strength estimation library. This overview explains what the gem is, why it exists, its core architectural principles, and how its major components work together. For installation and usage instructions, see Getting Started. For detailed API documentation, see API Reference. For in-depth architectural details, see Architecture. Sources: README.md1-52 lib/zxcvbn.rb1-18 zxcvbn-js is a Ruby gem that enables server-side password strength validation using the same zxcvbn algorithm used on the client side.

Rather than reimplementing the password strength logic in Ruby, this gem executes the original JavaScript implementation via the ExecJS library, ensuring identical results between client-side and server-side validation. The gem provides two primary interfaces: Zxcvbn.test - A simple convenience method for testing individual passwordsZxcvbn::Tester - A performance-optimized class for testing multiple passwords Sources: README.md3-10 lib/zxcvbn.rb5-17 lib/zxcvbn/tester.rb1-17 The primary motivation for zxcvbn-js is to maintain consistency between client-side and server-side password validation.

Many applications perform password strength checks in the browser using zxcvbn.js, but also need to validate passwords on the server. By executing the same JavaScript code on both sides, zxcvbn-js eliminates discrepancies that would occur with separate implementations.

This approach provides several advantages: - Identical validation results on client and server - No maintenance of parallel implementations in different languages - Automatic updates when the underlying zxcvbn.js library is updated - Consistent user feedback regardless of validation location Sources: README.md6-8 System Context Diagram: Shows how zxcvbn-js fits within a typical Ruby application and its relationship to client-side validation. Sources: README.md1-10 lib/zxcvbn/tester.rb2-9 The zxcvbn-js gem implements a cross-language bridge pattern where Ruby code acts as a thin wrapper around the JavaScript implementation.

No password strength logic is implemented in Ruby. Core Architecture Diagram: The layered structure showing Ruby, bridge, and JavaScript components.

Sources: lib/zxcvbn.rb8-16 lib/zxcvbn/tester.rb7-15 README.md32-46 Zxcvbn.test The Zxcvbn.test(password, user_inputs = []) method lib/zxcvbn.rb13-16 provides a convenient one-line interface for testing a single password.

It creates a new Tester instance for each call, which means: - Easy to use - no object lifecycle management required - Stateless - no memory persists between calls - Slower - loads ~20MB of dictionaries on every invocation Use when: Testing individual passwords infrequently.

Sources: lib/zxcvbn.rb8-16 README.md20-30 Zxcvbn::Tester The Zxcvbn::Tester class lib/zxcvbn/tester.rb4-16 loads the JavaScript dictionaries once during initialization, then reuses the execution context for multiple password tests: - More efficient - amortizes dictionary loading cost - Higher memory usage - maintains ~20MB RSS for the JavaScript context - Requires lifecycle management - application must create and manage the instance Use when: Testing multiple passwords in batch or high-throughput scenarios.

Runtime dependencies: execjs - Required for JavaScript execution lib/zxcvbn/tester.rb2 zxcvbn-js.gemspec18- A JavaScript runtime supported by ExecJS (Node.js, MiniRacer, etc.) Development dependencies: therubyracer - V8 JavaScript engine for testing zxcvbn-js.gemspec20rspec - Test framework zxcvbn-js.gemspec21 Sources: zxcvbn-js.gemspec18-21 lib/zxcvbn/tester.rb2 The gem deliberately does not reimplement the password strength algorithm in Ruby.

Instead, it executes the original JavaScript code via ExecJS. This decision ensures: - Perfect consistency with client-side validation - Reduced maintenance burden (only one implementation to update) - Automatic bug fixes when updating the JavaScript asset Sources: README.md6-8 The data/zxcvbn.js file data/zxcvbn.js1-2 contains approximately 20MB of dictionary data including common passwords, English words, names, and keyboard patterns.

This data is: - Bundled with the gem for offline usage - Loaded into memory during JavaScript context initialization - Shared across all password tests in the same Tester instance Sources: lib/zxcvbn/tester.rb5 README.md34 Providing both Zxcvbn.test and Zxcvbn::Tester allows users to choose between convenience and performance based on their specific use case: - Infrequent validation → use Zxcvbn.test - Batch validation or high throughput → use Zxcvbn::Tester Sources: lib/zxcvbn.rb8-16 lib/zxcvbn/tester.rb4-16 README.md32-46 Current version: 4.4.3 lib/zxcvbn/version.rb2 The version number tracks the underlying zxcvbn.js library version to maintain clarity about which JavaScript implementation is being used.
