  2. Wechaty v0.40+
  3. Wechaty Plugin Contrib

Adding Event Logger plugin​

For the demonstration of adding this plugin, we will use the Starter Bot and show you how to add the EventLogger plugin to it. Follow the steps below:

1. Create a starter bot​

Follow the instructions on the Starter Bot page to create the foundation of a Wechaty bot.

2. Install dependency​

As the EventLogger plugin is present in the wechaty-plugin-contrib NPM package, you have to first add it to the dependencies. It can be installed using the following command:

npm i wechaty-plugin-contrib

3. Integrate the plugin​

Inside the event-logger-bot.ts file, import the plugin:

import { EventLogger } from 'wechaty-plugin-contrib'

Now, just before starting the bot, you can use this plugin:

// Add the following line to use the plugin
bot.use(EventLogger())
bot.start()

4. Run the bot​

In order to run the bot, first you have to export/set an environment variable with the type of puppet to use, and then start the bot:

export WECHATY_LOG=verbose
export WECHATY_PUPPET=wechaty-puppet-wechat
make bot
# the above is equals to the below command:
# npm start
#   or, npx ts-node examples/ding-dong-bot.ts

EventLogger plugin output

Congratulations! You have successfully integrated the EventLogger plugin to your Wechaty bot. You will see after running the bot, it starts logging the Wechaty events.
