Kitchen Sink Bot

A kitchen-sink LINE bot example

Requirements

Install npm dependencies:

npm install

Also, FFmpeg and ImageMagick should be installed to test image and video echoing.

Configuration

Create .env file in the root folder with these variables.

CHANNEL_SECRET=YOUR_CHANNEL_SECRET
CHANNEL_ACCESS_TOKEN=YOUR_CHANNEL_ACCESS_TOKEN
BASE_URL=https://your.base.url # remove BASE_URL if you run it locally
PORT=80

Run webhook server

npm start

With the configuration above, the webhook listens on https://your.base.url:80/callback.

ngrok usage

ngrok tunnels external requests to localhost, helps debugging local webhooks.

This example includes ngrok inside, and it just works if no BASE_URL is set. Make sure that other configurations are set correctly.

❯ npm start

...

It seems that BASE_URL is not set. Connecting to ngrok...
listening on https://ffffffff.ngrok.io/callback

The URL can be directly registered as the webhook URL in LINE Developers console.
