:book: Resource

Wechaty already held lots of talk and got a lot of blogs in the past 4 years, here is all of the wechaty resources:

:rocket: The World's Shortest ChatBot Code: 6 lines of JavaScript

const { Wechaty } = require('wechaty') // import { Wechaty } from 'wechaty'

Wechaty.instance() // Global Instance .on('scan', (qrcode, status) => console.log(Scan QR Code to login: ${status}\nhttps://wechaty.js.org/qrcode/${encodeURIComponent(qrcode)})) .on('login', user => console.log(User ${user} logged in)) .on('message', message => console.log(Message: ${message})) .start()

Notice: Wechaty requires Node.js version >= 12

This bot can log all messages to the console after login by scan.

You can find Wechaty Official Example at examples/ding-dong-bot.ts, and more from our Example Directory.

:checkered_flag: Requirements

  1. Node.js v12
  2. sudo apt-get install build-essential && sudo snap install shellcheck

clone
&
npm install
&
npm start
.

If you are new to Wechaty and want to try it the first time, we'd like to strong recommend you starting from this repository, and using it as your starter template for your project.

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 Version npm (tag)

Downloads install size

node bot.js

2. Docker

Docker Pulls Docker Layers

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

3. Switch Protocol(Puppet)

Wechaty is very powerful that it can run over different protocols. You can specify the protocol by set the environment variable

WECHATY_PUPPET
to different puppet provider.

If you cannot use Web protocol, you can apply other protocal following the instruction here: https://github.com/wechaty/wechaty/wiki/Support-Developers We provide free token to support developers build a valuable WeChat chatbot.

Currently we support the following puppet providers:

| Protocol | Puppet Provider | Environment Variable | | --- | --- | --- | | Web | PuppetPuppeteer |

export WECHATY_PUPPET=wechaty-puppet-puppeteer
| | Mock | PuppetMock |
export WECHATY_PUPPET=wechaty-puppet-mock

CREATING WECHATY PLUGIN

Creating and publishing a Wechaty Plugin is simple. Simply expose your module as a function that takes 1 parameter: wechaty. When your plugin is imported by Wechaty, it will pass itself in as the argument, and so you are free to add any configuration that Wechaty supports.

import { WechatyPlugin } from 'wechaty'

export default const MyPlugin: WechatyPlugin = (wechaty: Wechaty) => { // ... }

The

config
exist so the user can pass in customizations to your Plugin. In documenting your Wechaty Plugin, you would lay out your supported config for the user.

:innocent: Find a Good Server

The best practice for running Wechaty Docker/NPM is using a VPS(Virtual Private Server) outside of China, which can save you hours of time because

npm install
and
docker pull
will run smoothly without any problem.

The following VPS providers are used by the Wechaty team, and they worked perfectly in production. You can use the following link to get one in minutes. Also, doing this can support Wechaty because you are referred by us.

| Location | Price | Ram | Payment | Provider | | --- | --- | --- | --- | --- | | Singapore | $5 | 512MB | Paypal | DigitalOcean | | Japan | $5 | 1GB | Paypal | Linode | | Korea | $10 | 1GB | Alipay, Paypal | Netdedi | | Singapore | $3.5 | 512MB | Alipay, Wechat | Vultr |

:poop: The Story

In 2017 ...

Huan's daily life/work depends on too much chat on wechat.

  • Almost 14,000 wechat friends in May 2014, before wechat restricts a total number of friends to 5,000.
  • Almost 400 wechat rooms, and most of them have more than 400 members.

Can you imagine that? He was dying...

So a tireless bot working for me 24x7 on wechat, monitoring/filtering the most important message is badly needed. For example, it highlights discussion which contains the KEYWORDS which he want to follow up(especially in a noisy room). ;-)

At last, It's built for huan's personal study purpose of Automatically Testing.
