Node
This project is an open-source JavaScript runtime built on the V8 engine. It provides a comprehensive environment for executing JavaScript code outside of a web browser, offering foundational primitives for process management, multi-core load distribution, and parallel execution through worker threads.
The runtime includes a broad set of built-in modules for system-level operations, such as file system interaction, network communication across various protocols, and cryptographic security. It supports multiple module systems, native binary addon integration, and diagnostic tools for monitoring application performance and health.
Developers can utilize built-in utilities for testing, debugging, and internationalization, as well as native support for executing TypeScript and WebAssembly. The project is distributed as a standalone runtime, with capabilities for bundling scripts into single executable files.
Features
- Event Emitters - An event-emitter pattern allowing objects to trigger named events and execute listener functions synchronously for decoupled communication between application components.
- Timer Schedulers - A global interface for scheduling functions to be executed at future intervals using timeouts and periodic intervals.
- Native Addons - A foreign function interface allowing the integration of native shared objects with the JavaScript runtime for high-performance extensions.
- Cryptographic Operations - A cryptographic utility providing hash, HMAC, cipher, decipher, sign, and verify functions for securing data and verifying integrity.
- Logging & Debugging - A debugging interface providing methods for writing to streams, with support for configurable output destinations and formatted logging.
- Performance Measurement - A performance-measurement interface providing high-resolution timing, user-defined marks, and resource-timing tracking for application profiling.
- Internationalization Utilities - A suite providing locale-sensitive string operations, Unicode-aware character processing, and standard internationalization support for global applications.
- Query String Parsers - A utility for parsing and formatting URL query strings to facilitate data exchange via web requests.
- Asynchronous Streams - A streaming interface based on asynchronous iterables, allowing data flow in batches without requiring base class extensions or complex boilerplate.
- Diagnostic Reports - A diagnostic tool that generates structured summaries of process state, including stack traces, heap statistics, and resource usage.
