TomaszRewak/TimeWriter

This system is a real-time collaborative text editor that enables multiple users to edit documents simultaneously. It manages document state through an event-sourcing architecture, supporting features like undo/redo, syntax highlighting, and multi-user cursor visualization. The application consists of a React-based client for the editing interface and a Node.js server that handles synchronization, persistence, and room-based broadcasting via Socket.IO.

A new sample file, sample-text.js, was added to the time-writer-event-sourcing/samples directory. It provides a basic React component example, likely for demonstration or testing purposes within the time-writer-event-sourcing context.

The time-writer-client application is now configured for initial deployment with a new Express server setup in app.js that serves static files and the main index.html page. The project includes a webpack configuration to bundle React/JSX source code into a single bundle.js file, using Babel for transpilation and CSS loaders for styling. This establishes the foundational structure for the client-side application, including the HTML template with a root div for React mounting and the necessary build tooling.

The time-writer-server introduces a new Node.js backend that serves the static frontend, exposes a REST endpoint to retrieve document history, and manages real-time collaboration via Socket.IO. The server automatically assigns timestamps to all events, broadcasts changes to connected clients in a room, and handles disconnections by removing carets. Additionally, a scheduled job runs daily to remove old documents, and the project is configured with Webpack for bundling.

A new TextDocument class has been added to manage document state and event history. It initializes with an optional event history (defaulting to a sample text and empty carets) and exposes the event store's history and state. It provides methods to add events and update timestamps, effectively encapsulating the document's lifecycle and data access.

Added new services for text formatting and navigation. The text formatting service now calculates indentation levels based on tab characters, while the text navigation service provides methods for line/column calculations, caret coordinate mapping, and fast text traversal.

Added a new workspace component that renders a top bar for managing open documents. Users can now select, close, and add new files via the workspace bar, with each document displayed as a selectable tab. The workspace also includes a user profile popup and links to external resources like GitHub and LinkedIn.

Adds two new services to the application: EventFactory, which translates keyboard and mouse interactions (such as Ctrl+Z for undo, Ctrl+Y for redo, and navigation keys) into structured events, and ServerConnection, which manages the Socket.IO connection for real-time document synchronization and state retrieval.

The document component has been refactored into a new structure that introduces syntax highlighting for code elements (comments, strings, statements, etc.) and supports multi-user cursor (caret) visualization. Users will see colored text fragments based on their type, distinct caret ranges for each connected user, and an input panel that handles keyboard and mouse interactions for editing, selection, and scrolling.

A new 'Logs' component has been introduced to the time-writer-react application, providing a dedicated UI for displaying the last 10 events from the history. This feature includes a toggle to show or hide the log panel, displays event data with syntax highlighting for object structures, and presents informational messages about the demo version's limitations, such as the 10,000 character document limit and 3-day inactivity removal policy.

The application's routing logic has been extracted into a new \routing.js\ module. This component now wraps the application in a \BrowserRouter\ and defines the root route (\/\) to render the \Workspace\ component, effectively replacing the previous home page setup.

The event history module now supports undo and redo operations, allowing users to revert or reapply changes. This is enabled by new classes that manage the event chain, including a reducer for adding/removing events, a state updater that tracks undo/redo levels per author, and a repair mechanism to fix timestamp ordering. Additionally, the system enforces a 10,000-character limit on file length and cleans up old states to manage memory.

The application now intercepts and prevents default behavior for specific keyboard inputs, including the spacebar, backspace, tab, and the Ctrl+A and Ctrl+S hotkeys. This ensures that these keys do not trigger native browser actions or navigate away from the page, providing a more controlled writing environment.

The document event processing logic has been refactored into a modular structure, introducing specific reducers for insertion, deletion, navigation, and caret management. This change introduces a new \EventReducer\ that routes events to specialized sub-reducers, each handling a specific type of document update. The system now supports vertical and horizontal navigation, caret creation and removal, and text insertion and deletion with improved position tracking and duplicate removal.

The time-writer-server now maintains an in-memory cache of documents, allowing the server to remember document state between requests. A new DocumentRepository class manages this cache, automatically creating new documents on first access and tracking their last-accessed time. Additionally, a mechanism has been added to automatically remove documents that have not been accessed in the last three days, ensuring the server's memory usage remains bounded.

Added unit tests for the TextNavigationService, covering scenarios for counting lines and calculating caret coordinates and positions. The test suite includes cases for empty strings, single and multi-line texts, and edge cases such as positions beyond the end of the text or lines.

The project has been initialized with a new dependency structure across multiple sub-projects (client, server, react, test). This includes adding Babel 7 (specifically @babel/core 7.2.0, @babel/polyfill 7.2.5, @babel/preset-env 7.1.6) for JavaScript transpilation and @babel/node for testing. The client and React components now depend on React 16.6.3 and React-DOM 16.6.3. Additionally, the server side incorporates Express 4.16.4, Socket.io 2.2.0, and Node-schedule 1.3.1, while the test environment uses Jasmine 3.3.1. These changes establish the foundational tooling and library versions for the application's frontend, backend, and testing infrastructure.
