etunnel 1.0.0

Expose a local service through an etunnel reverse-tunnel server with one line of code.

etunnel for Dart

dart:io only, zero dependencies.

Zero registration: every SDK client speaks the same tiny wire protocol (PROTOCOL.md) against any etunnel server (default wss://t.ggcode.uk/tunnel).

Install

dart pub add etunnel

Requires Dart ^3.0.

CLI

dart run etunnel.dart 3000

Prints TUNNEL_URL: https://<subdomain>.t.ggcode.uk — that URL now routes to your local service. Ctrl-C closes the tunnel.

Embed

See the header of the source file for the embed example.

MIT — see LICENSE. Buffer-based protocol client: request and response bodies are buffered per stream (fine for webhooks/dashboards/demos; use the Go SDK for streaming and WebSocket pass-through).
