stringsby

Stringsby is a lightweight, language-agnostic library designed to simplify string manipulation by providing an immutable, fluent API for common transformations. It emphasizes readability and predictable behavior by chaining operations and returning new string values instead of mutating the original data.

Origins and design: Stringsby emerged in the early 2020s as part of a broader trend toward expressive, dependency-light utility libraries. The design centers on immutability, Unicode safety, and locale-aware operations, with a small core set of primitives and extensible modules for tasks such as trimming, padding, case conversion, substring, search and replace, and pattern matching. The API favors chaining and functional style, allowing operations to be composed in a single expression.

Usage and ecosystem: Typical usage involves creating a stringsby value from a source string and applying a sequence of transformations. For example, convert to uppercase, trim whitespace, and normalize spaces, all in a single expression, with the result accessible via a final value or method. It supports lazy evaluation in some implementations to optimize performance and reduces allocations in hot paths. The library is distributed under permissive licenses and is available for multiple ecosystems, including JavaScript, Python, and others.
