Loading... Loading... Menu This guide is for developers who want to contribute to zxcvbn-js or understand its development workflow. It covers the development environment setup, project organization, and the tools used for building and maintaining the gem. For detailed information about specific aspects, see: - Project file organization: Project Structure - Rake tasks and build tools: Build and Development Tools - Gem packaging and release: Gem Distribution The zxcvbn-js gem has minimal Ruby code since it wraps the JavaScript implementation.

Ruby (2.0 or later recommended) - Bundler for dependency management - A JavaScript runtime (for development and testing, therubyracer is used) - Git for version control The project has two categories of dependencies defined in zxcvbn-js.gemspec18-21: Runtime Dependency: execjs - Required for executing the JavaScript implementation from Ruby Development Dependencies: therubyracer - V8 JavaScript engine for testingrspec - Testing framework Sources: zxcvbn-js.gemspec1-22 Rakefile1-18 README.md1-52 Sources: Rakefile1-18 zxcvbn-js.gemspec1-22 lib/zxcvbn/version.rb1-3 The repository follows a standard Ruby gem layout with some JavaScript-specific additions: Sources: zxcvbn-js.gemspec11-16 Rakefile1-18 Sources: lib/zxcvbn/tester.rb1-17 lib/zxcvbn/version.rb1-3 zxcvbn-js.gemspec1-22 Rakefile1-18 The Rakefile1-18 defines two primary development tasks: The rake console task Rakefile5-13 provides an IRB session with the gem pre-loaded for interactive testing: This task: - Loads the Zxcvbn module - Includes JsHelpers for direct JavaScript testing capabilities - Starts an IRB session for manual experimentation Usage: Example session: The rake compile_coffeescript task Rakefile15-18 compiles CoffeeScript test sources: This task: - Compiles CoffeeScript files to JavaScript - Concatenates multiple JavaScript files into compiled.js - Used when modifying or updating the test JavaScript sources Note: This task is rarely needed in normal development since the test infrastructure primarily uses the production JavaScript asset.

Sources: Rakefile1-18 The gem version is managed through the Zxcvbn::VERSION constant defined in lib/zxcvbn/version.rb1-3: This constant is: - Referenced by zxcvbn-js.gemspec16 to set gem.version - The single source of truth for the gem version - Updated manually when preparing a new release The current version 4.4.3 tracks the version of the underlying zxcvbn.js JavaScript library to maintain consistency.

Sources: lib/zxcvbn/version.rb1-3 zxcvbn-js.gemspec16 Developers have two approaches for testing changes: - Interactive Testing: Use rake console to manually test password strength calculations - Automated Testing: Run bundle exec rspec to execute the full test suite The test infrastructure is described in detail in Test Infrastructure.

Sources: Rakefile5-13 README.md23-30 When contributing to zxcvbn-js, developers typically: - Make Changes - Edit Ruby wrapper code in lib/zxcvbn/ - Update Tests - Add or modify tests in spec/ - Test Manually - Use rake console for interactive verification - Run Test Suite - Execute bundle exec rspec to ensure all tests pass - Update Documentation - Modify README.md if API changes - Prepare Release - Update Zxcvbn::VERSION if releasing The codebase is intentionally minimal - most "development" involves: - Maintaining the Ruby-JavaScript bridge in lib/zxcvbn/tester.rb1-17 - Ensuring test coverage remains comprehensive - Updating the data/zxcvbn.js asset when the upstream library updates Sources: lib/zxcvbn/tester.rb1-17 lib/zxcvbn/version.rb1-3 README.md1-52 Understanding the architectural decisions helps when contributing: The gem intentionally contains no Ruby implementation of password strength logic.

This means: - Ruby code changes are rare and typically involve: - API surface modifications in Zxcvbn module - Performance optimizations in Zxcvbn::Tester - ExecJS integration adjustments - API surface modifications in - JavaScript updates involve: - Replacing data/zxcvbn.js1 with a newer version from upstream - No modification of the JavaScript code itself The lib/zxcvbn/tester.rb7-14 demonstrates the core pattern: Key points for developers: ExecJS.compile loads and parses the ~20MB JavaScript file- Context is persistent across multiple test calls for performance - JSON serialization handles Ruby-to-JavaScript data conversion - Results are wrapped in OpenStruct for convenient Ruby access Sources: lib/zxcvbn/tester.rb1-17 README.md7-8 When the upstream zxcvbn.js releases a new version: - Download the new zxcvbn.js from https://github.com/dropbox/zxcvbn - Replace data/zxcvbn.js1 with the new version - Run bundle exec rspec to verify compatibility - Update lib/zxcvbn/version.rb2 to match the new version - Update README.md1-52 with any API changes To add functionality to the Ruby wrapper: - Add the method to the Zxcvbn module orZxcvbn::Tester class - Implement it using ExecJS context evaluation if JavaScript access is needed - Add tests in spec/zxcvbn_spec.rb - Document in README.md - Consider performance implications (see Performance Considerations) - Write a failing test that demonstrates the bug - Debug using rake console withJsHelpers for direct JavaScript comparison - Fix the Ruby wrapper code - Verify the fix with bundle exec rspec - Ensure the fix doesn't break existing behavior Sources: lib/zxcvbn/tester.rb1-17 lib/zxcvbn/version.rb1-3 Rakefile5-13 Refresh this wiki - Development - Development Environment - Prerequisites - Dependencies - Setting Up for Development - Development Workflow Diagram - Repository Structure Overview - Key Development Files - Development Tasks - Interactive Console Task - CoffeeScript Compilation Task - Versioning Strategy - Testing During Development - Contributing Workflow - Design Philosophy for Developers - Minimal Ruby Implementation - Cross-Language Bridge Pattern - Common Development Scenarios - Scenario 1: Updating the JavaScript Asset - Scenario 2: Adding a New Ruby Method - Scenario 3: Fixing a Bug
