  .on('login',            user => console.log(`User ${user} logged in`))

Otherwise, please saved the above The World's Shortest ChatBot Code: 6 lines of JavaScript example to a file named bot.js before you can use either NPM or Docker to run it.

1. Npm

npm init
npm install wechaty

# create your first bot.js file, you can copy/paste from the above "The World's Shortest ChatBot Code: 6 lines of JavaScript"
# then:
node bot.js

2. Docker

• Wechaty Starter Repository for Docker - https://github.com/wechaty/docker-wechaty-getting-started

Wechaty Docker supports both JavaScript and TypeScript. To use TypeScript just write in TypeScript and save with extension name .ts, no need to compile because we use ts-node to run it.

# for TypeScript
docker run -ti --rm --volume="$(pwd)":/bot wechaty/wechaty bot.ts
