## What it is
A TypeScript monorepo of small libraries that transform strings between naming conventions like camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE. It ships as pure ESM packages with TypeScript definitions.

## Use cases
- convert strings between camelCase and snake_case
- transform identifiers to PascalCase in generated code
- normalize API field names to kebab-case
- convert text to title case or CONSTANT_CASE
- swap or sponge-case strings for fun text effects

## When to choose
- you need reliable, well-tested case conversion in JavaScript or TypeScript
- you want tiny focused ESM packages with type definitions
- you are building code generators or API serializers that need identifier transformations

## When to avoid
- you need CommonJS require support or legacy Node module resolution
- you need locale-aware natural-language title casing with complex rules
- you work outside the JavaScript ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: serialization, developer-tools
- domain: developer-tools, web-development, text-editors
- platform: cross-platform, browser
- tags: string-manipulation, case-conversion, typescript, esm, monorepo, nodejs
