🆖 Using ngrok

Ngrok URL can be directly registered as the webhook URL in LINE Developers console means you can host your bot on your system

🤖 Easily create new commands

you can make new command by creating .js file on the commands/{category} folder like this

module.exports = {
  command: 'text',
  aliases: ['ping'],
  category: "example",
  description: 'Text message example',
  handler: (client, blobClient, event) => {
    
    client.replyMessage({
      replyToken: event.replyToken,
      messages: [
      {
      type: 'text',
      text: 'This is text message example'
      }
      ]
    });
  },
};

Alternatively you can use user snippets that come with this repo :

Snippets	Descriptions
command	Create new command handler
replyMessage	create new replyMessage structure
postback	Create new postback handler

see example for other message.type

📃 Displaying rich menu

It's a very rough method of handling rich menu if not the worst :< Uncomment these lines of code below in index.js to create a new rich menu everytime bot is running, there is not so many use cases i can think of when using rich menu. Maybe you can.

More about Rich menu can be found here : https://developers.line.biz/en/docs/messaging-api/using-rich-menus/
