A collection of utilities for working with Uint8Array and Buffer in JavaScript/TypeScript, including conversions, comparisons, and encoding helpers.
uint8array-extras is a JavaScript/TypeScript utility library that provides essential functions for working with Uint8Array and Buffer objects. It offers drop-in replacements for common Buffer methods, helping developers transition from Node.js-specific Buffer to the standard Uint8Array while maintaining compatibility and adding browser support.
JavaScript and TypeScript developers working with binary data, file processing, or network protocols who need to handle Uint8Array/Buffer operations across Node.js and browser environments.
Developers choose uint8array-extras because it provides a comprehensive, tree-shakable collection of utilities that solve real-world Uint8Array/Buffer problems with proper Unicode support, browser compatibility, and clean API design that mirrors familiar Buffer methods.
Useful utilities for working with Uint8Array (and Buffer)
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides browser-compatible utilities for Uint8Array operations, explicitly addressing Unicode support in Base64 conversions where native browser methods like btoa/atob fail, as noted in the README.
Built as a tree-shakable library, allowing developers to import only necessary functions, reducing bundle size in web applications, which is highlighted in the package philosophy.
Offers drop-in replacements for common Buffer methods like concat, equals, and toString, with API examples mirroring Node.js Buffer, easing the transition to standard Uint8Array.
Includes multi-encoding string conversions (e.g., UTF-8, Big5, Shift-JIS) and URL-safe Base64 options, detailed in the uint8ArrayToString and stringToBase64 methods with practical examples.
Does not implement all Buffer methods, such as those for streams or advanced encoding like 'ucs2', requiring additional libraries or custom code for full Buffer parity.
As a JavaScript library layer, it may introduce slight performance overhead compared to native Buffer methods in Node.js, especially for high-frequency binary data operations.
Adds an external dependency, which could be unnecessary for projects with minimal Uint8Array needs or those prioritizing dependency-free architectures.
