messaging-api-line

A Node.js client library for the LINE Messaging API, version 1.1.0. Maintained as part of the Yoctol messaging-apis monorepo, it provides a comprehensive, TypeScript-first wrapper for LINE's REST endpoints including reply, push, multicast, broadcast, and rich menu APIs. The library uses axios for HTTP and wraps errors for better debugging. Key differentiators: full TypeScript types, camelCase key support (v1.0.0+), factory methods for message creation, and support for Flex and Imagemap messages. Release cadence is sporadic with the last release in October 2021.
