I'm implementing Access Token and Refresh Token using JWT for login function in NodeJS application. I'm trying to use Redis to store the Refresh Token, but I'm getting the following code :
const redis = require('redis');
require('dotenv').config({ path : __dirname + '/../config/env/.env' });
let redisClient;
redisClient = redis.createClient(6379, '127.0.0.1');
module.exports = redisClient;
'use strict';
const JwtUtil = require('../../middlewares/jwt-util');
const redisClient = require('../../middlewares/redis');
const authRouter = require('express').Router();
const jwt = new JwtUtil();
authRouter.post('/user-token/generate', (req, res, next) => {
const accessToken = jwt.sign(req.body);
const refreshToken = jwt.refresh();
redisClient.set(req.body.id, refreshToken);
res.status(200).send({
result : 'success',
data : {
accessToken,
refreshToken
}
});
});
module.exports = authRouter;
I have printed several logs, but it seems that redisClient.set(req.body.id, refreshToken); in authRoute.js. There seems to be an error in.
UnhandledPromiseRejectionWarning: Error: The client is closed
(node:24640) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
Access Token and Refresh Token are issued normally. Also, the following code doesn't work. I'm not sure how I should rewrite the code. What should I do?
redisClient.on('connection', () => {
console.info('Redis connected!');
}
Although I'm using the Windows, I downloaded Redis, performed a ping test, and confirmed that the server is running.
As for now I am able to solve partially to get data, but for set data still not done for redis v4. #redis #v4 # redisv4
app.get('/data',(req,res) => {
// check in redis first
//console.log(">>>>url",url)
(async () => {
const userInput = (req.query.country).trim()
const url = `https://en.wikipedia.org/w/api.php?action=parse&format=json§ion=0&page=${userInput}`
const client = createClient({
host:'localhost',
port:6379});
client.on('error', (err) => console.log('Redis Client Error', err));
await client.connect();
const response = await client.get(`${userInput}`)
if(response){
const output = JSON.parse(response);
res.send(output)
}
})();
})
I implement connect to redis v6.2 this way in index.js start file.
const redis = require('redis');
const redisCache = createClient({
url: redis://localhost:6379
});
redisClient.on('connect', () => console.log('Connected to Redis!'));
redisClient.on('error', (err) => console.log('Redis Client Error', err));
redisClient.connect();
module.exports = redisClient;
