    pretty-bytes

    Convert bytes to a human readable string: 1337 → 1.34 kB

    clsx

    clsx

    A tiny utility for constructing `className` strings conditionally

    ...It then returns a deduplicated, space-separated class string that can be applied directly to HTML or JSX className attributes. The library is distributed in multiple formats (ESM, CommonJS, and UMD) so it works well in bundlers, Node environments, and direct tags. Because it has zero dependencies and a stable API, it is widely used in both small projects and large production codebases where bundle size is a concern.

    Classnames

    Classnames

    A simple javascript utility for conditionally joining classNames

    Classnames is a minimal JavaScript utility that helps you construct CSS class strings based on conditional logic. Instead of manually concatenating strings, developers can pass any combination of strings, arrays, or objects, and the library will output a clean, space-separated class list. When you provide an object, the keys represent class names and the boolean values determine whether each class should be included in the final string.

    Twemoji

    Twemoji

    Simple library that provides standard Unicode emoji for all platforms

    ...The graphics are licensed under the CC-BY 4.0 which has a pretty good guide on best practices for attribution. Although there are two kinds of parsing supported by this utility, we recommend you use DOM parsing, explained below. Each type of parsing accepts a callback to generate an image source or an options object with parsing info. The second kind of parsing is string parsing. This is unrecommended because this method does not sanitize the string or otherwise prevent malicious code from being executed; such sanitization is out of scope.

    Multiline

    Multiline

    Multiline strings in JavaScript

    Multiline is a small JavaScript utility created to make multiline strings easier to write before template literals became standard. It extracts the contents of a block comment placed inside an anonymous function and returns that text as a string. This avoids long chains of concatenated strings or arrays joined with newline characters. A stripIndent helper removes redundant leading indentation while preserving the intended layout.
