signal-bot-node

Signal-Bot

A library for creating bots that interact with the Signal application. Not affiliated with the Signal project or Open Whisper Systems. This implementation bases on the abandoned signal-bot.

Install with npm install signal-bot-node.

Currently, only tested on Linux, with Node.js >=18.0.0.

This library requires a working installation of signal-cli running in daemon mode with the phone number you want to use, or the multi-account feature enabled.

Tested on v0.13.1 of signal-cli.

Attention: this library is currently under heavy development and not ready for production use.

Example Usage

Basic Commands

const {Client} = require("signal-bot");

const bot = new Client();

const prefix = "!";

bot.on("message", msg => {
  if (!msg.content.startsWith(prefix)) return;
  const command = msg.content.slice(prefix.length);

  if (command === "hello") {
    msg.conversation.sendMessage("Hello World!");
  } else if (command === "whoami") {
    msg.conversation.sendMessage(`You are ${msg.author.id}`);
  }
});

bot.connect();

Send the bot !hello and it should respond with Hello World!.

Send the bot !whoami and it should respond with You are <phone number>.
