Redis Middleware using in nodejs express js.

redis.js

const redis = require("redis");
const redis_url = process.env.REDIS_URL || null;
const client = redis.createClient(redis_url);


module.exports = {
  getCached: (req, res, next) => {
    const { redis_key } = req.headers
    client.get(redis_key, function(err, reply) {
      if (err) {
        res.status(500).json({
          message: "Somethin Went Wrong"
        })
      }
      if (reply == null) {
        next()
      } else {
        res.status(200).json({
          message: `Success Read ${redis_key}`,
          data: JSON.parse(reply)
        })
      }
    });
  },
  caching: (key, data) => {
    client.set(key, JSON.stringify(data) )
  },
  delCache: (key) => {
    client.del(key)
  }
}

hello brother, how to use this middleware. it is not a function?

yeah it is, You pass it to your route before the controller something like router.get('/url', getCached, controller.control). he's exporting as an object so i think you destructure the import
