Open-source alternatives to Javascript

AndroidUtilCode is an Android utility library and system API wrapper designed to reduce development boilerplate. It provides a collection of helper classes for common tasks including system settings management, file I/O, and hardware access. The project distinguishes itself through a comprehensive toolset for device management and UI assistance. It includes specialized capabilities for monitoring battery status, managing system volume and brightness, and implementing UI helpers to prevent duplicate click events. It also provides a dedicated system for coordinate conversion between different m

Common.Utility is a general purpose utility library providing a collection of helper classes for common programming tasks. It functions as a data security framework, a database access wrapper, and a suite of tools for system administration and network communication. The library includes a multimedia processing suite for generating barcodes and QR codes, editing images, and converting video formats. It also provides a network communication toolkit for managing HTTP requests and FTP transfers, as well as integration with email and notification services. The project covers a broad set of capabi

Locutus is a multi-language utility library and polyfill collection written in TypeScript. It provides a comprehensive set of implementations for standard library functions from various programming languages, enabling developers to use familiar semantics and behaviors across different technical environments. The library functions as a cross-language standard library, porting core logic and utilities from diverse languages into a type-safe TypeScript toolset. It focuses on maintaining consistent behavior through a polyfill-based design that replicates the original functionality of these foreig

shortid is a library for creating compact, non-sequential strings used as unique identifiers for database records and public URLs. It functions as a URL-friendly identifier utility designed to produce short alphanumeric strings. The project allows for the use of a custom alphabet to control the visual appearance of identifiers and avoid ambiguity. This custom character set mapping ensures that generated keys meet specific formatting or branding requirements. The system includes capabilities for non-sequential key generation to prevent resource enumeration, as well as tools to validate whethe

Collision-resistant ids optimized for horizontal scaling and binary search lookup performance.

i18next is a JavaScript localization library and internationalization framework used to translate application text into multiple languages. It functions as a dynamic translation manager that handles translation resources, language detection, and the mapping of unique keys to localized strings. The system features a pluralization and interpolation engine that applies language-specific grammatical rules for numeric counts and injects dynamic variables into strings. It utilizes a plugin-based backend architecture to load and cache translation namespaces from various sources, including remote ser

The line with the least number of leading whitespace, ignoring empty lines, determines the number.

Finds differences between two JSON object and generates operational transformation (OT) operations for transforming the first object into the second according to the JSON0 OT Type.

jsdiff is a JavaScript text diffing library and comparison engine used to compute differences between strings or arrays. It identifies additions and removals between blocks of text and provides a system for generating and applying formatted Unix-style patches. The toolkit functions as a customizable token differ, allowing for the comparison of arbitrary token sequences using user-defined equality and tokenization rules. This enables the creation of specialized comparison tools for non-standard text or data formats. Comparison capabilities are available at the character, word, and line levels

Stegcloak is a unicode steganography library and text-based data concealment tool. It provides a toolkit for hiding encrypted, compressed secret messages within standard text strings by mapping binary data to invisible, non-printing Unicode characters. The project combines a symmetric encryption toolkit with an invisible character encoder to ensure secure data concealment. It utilizes password-based key stretching and authenticated symmetric encryption to protect hidden payloads from unauthorized access and tampering. The system covers the full steganography workflow, including payload compr

Lightweight simple translation module for node.js / express.js with dynamic json storage. Uses common ('...') syntax in app and templates.

Replace all homoglyphs with base characters. Useful to detect similar strings.

Translate standard UUIDs into shorter formats and back.

This project is a UUID generation library providing a standards-compliant implementation of RFC 4122. It serves as a tool for creating and validating universally unique identifiers across multiple versions to ensure global uniqueness and prevent data collisions. The library supports several generation methods, including random-based entropy, timestamp sequencing, and namespace-based hashing. It also includes utilities for identifier validation, parsing, and converting identifiers between hexadecimal string representations and binary byte arrays. A command line utility is included for the man

Nanoid is a library for generating unique, fixed-length identifiers designed for distributed systems and database indexing. It produces compact, URL-safe strings by mapping random byte values to a custom character set, allowing for consistent memory allocation and predictable indexing performance across independent nodes without the need for central coordination. The library distinguishes itself by utilizing system-level, cryptographically secure entropy sources to ensure that every generated identifier is statistically unpredictable. This approach provides resistance against collision attack
