tls-client-node

Node.js wrapper for bogdanfinn/tls-client providing browser-like TLS fingerprinting via JA3, HTTP/2, and HTTP/3. Version 0.1.13 is current, with frequent releases. Uses a managed sidecar process (tls-client-api) by default for predictable async concurrency, with an optional native shared-library mode. Ships strict TypeScript types, supports ESM and CJS, and keeps lifecycle explicit through TLSClient and Session objects. Differentiates from node-tls-client by avoiding singleton state and aligning payloads closely with the upstream Go library. Requires Node.js >=18.17 and downloads platform-specific binaries during postinstall.
