available via npm run-script: dev nodemon ./bin/www

Is this coming from the version of nodejs and npm? I am using the latest version as below: npm: 6.14.5 node: v12.18.2

Thanks

The medium post was a little bit old, pls check out the readme here in the repo:

const {Wechat} = require('wechat-jssdk');
const wx = new Wechat(wechatConfig);
