custom-string-formatter

Customizable String Formatter is a lightweight library for replacing variables in strings with custom value formatting. Version 1.2.1 supports Node.js 18+ and all modern browsers. It features a flexible variable syntax including nested properties, filter pipelines, and filter arguments. The library is ESM-only, ships TypeScript definitions, and emphasizes performance with fast value resolution. Key differentiators include support for multiple variable syntaxes (${}, $(), $<>), chained filters with arguments, and custom formatter/filter interfaces.
