const client = new LineBot({
  channelToken: '<insert client token>',

})

// Using Express
app.post('/', bodyParser.json({ verify: (req, res, buf) => req.rawBody = buf }), (req, res) => {

  if (!client.validateSignature(req.rawBody, req.headers['x-line-signature'])) {
    res.sendStatus(400)
    return
  }

  // Retrieve the request's body and parse it as JSON
  const eventJson = JSON.parse(req.rawBody)
  eventJson.events.forEach(event => {
    switch (event.type) {
    case 'message':
      switch (event.message.type) {
      case 'text':
        const message = {
          type: 'text',
          text: event.message.text
        }
        client.replyMessage(event.replyToken, message)
          .then((response) => {
            console.log(response)
          })
          .catch((response) => {
            console.log(response.body)
            console.log(response.status)
          })
        break
      }
      break
    }
  })
  res.sendStatus(200)
