Node.js SDK for MailerLite API v2, version 1.2.0. It is a thin wrapper around Axios providing authentication, automatic camelCase conversion for request/response, TypeScript type definitions, and shorthand methods for MailerLite endpoints (account, campaigns, groups, segments, subscribers, webhooks, etc.). The library resolves API responses to body only (not full Axios response). It uses a default base URL of https://api.mailerlite.com/api/v2/ and offers options to override Axios config and headers. Release cadence is low; last release was over 2 years ago. Differentiators: built-in camelCase conversion and TypeScript support, unlike simpler wrappers.
