Thx Man ! I'm using Redis for my own project and it's working so far. But I didn't know about the built in promisify function in node lol. I can say it helps a lot because it's was a hard work to deal with the callback on each Redis GET function ( GET, HGET, HGETALL ... ). I was watching this kinda video just to find things like this, little but very helpful. This video is one top of that very clear for beginners.
The latest version of redis is asynchronous so no need to make custom functions. You can simply use the client. For instance, const reply = await client.GET(`rockets`) await client.setEx("recipes", 5, JSON.stringify(response.data)) const reply = await client.GET(`rocket-${id}`) await client.setEx(`rocket-${id}`, 5, JSON.stringify(response.data))
Priceless tutorial thank you keep it up. great vibe and flow man thank you. just couple Qs please 1. How long can is it ok to keep cache if data is not changing often? 2. What do I need to to do in order to deploy apps with Redis? cheers bro
One more question..how much memory it requires to handle proper redis and in what type of application redis can be used...small applications? Thank you so much for your previous answer

I have one question ..what if we have database and web server both on same machine.will it be useful to use redis cache or we can make direct call because server and database are on same machine?
If ur doing server side rendering, then u shud use a templating engine like “EJS”, you can watch this video to see how ejs works ruclips.net/video/BXuR6ucscJk/видео.html though it’s a video to create short links but ejs part remains the same.
@@mafiacodes Actually my questions was incorrect, it was about caching the html itself and rendering cached html rather than data(json). Wanted to implement this: res.render('showList',{shows:data},async(err,html)=>{ await client.setAsync('movieList',html); res.send(html); Thank you. I watched the ejs video too.
A cache's primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer. In a messaging app or notifications - data is fetched quickly, so should you cache - NO.

The Best Video I Got It After Searching 3 consecutive days
Just discovered your channel and I’m binge watching all your nodejs videos. Thank you for this🙌🏻🔥
Same here 💫
Thank you for this video bro... Really this is helpful for my new project... Clear explanation.... Thank you so much man... keep rocking...
I used Redis with Php, I found an excelent video and explanation for Node Js. Congrats! Thank U!!
very well explained. i never found out how to use redis. the answer is here. please do come up with more such videos.

Kudos. Great job and really well done - bare minimum dependencies to demonstrate the basics of get/set within a Node environment. Thank you!
Glad you enjoyed it!
Wow this is some of the cleanest code I've seen in a while. Thank you.
You're welcome!

Best tutorial for redis. Thanks man. I like the way you write code(like me😀). Clean and easy to understand.
Thanks for this! Your explanation was very clear and it was very easy to grasp everything. Looking forward to learning more about Redis caching.
Glad it was helpful!
your videos are direct to the point everytime. I like this
thank you so much, earlier I thought implementation of radis will be tough. Thankx alot

Same questions
Thanks for the tutorial its really very helpful. 😊
Great video bro, You are awesome !!
Sir which host we should mention when deploying server
Sir , please make a video on what to do if we have backend as MongoDB, that is how to integrate Redis with MongoDB. Thanks, you are the best.
Superb video
easy to understand, thank you :))

Hi,
Can i use this if I am changing my api's data every other day?
Yes, provide a refresh interval related to ur use case
thank you soo much brother!!!
will be great if you can make a video on testing for our API & add it to this series cant wait & thanks
stay motivated you're awesome !
Which API?

I need one help in redis i write one client.get middle to get all values but how to make dynamic so that in all routes its work
But if I want cache data like more than in 5sec
amazing!
Thank you.
can someone please explain why some people use hmset() to store a java object?
sir, which font do you use on editor? pl suggest
...
Operator mono
Can you please share Theme you are using along with Fonts Family name?
Snazzy operator theme, operator mono font
Bro please make video on proguard..
I have one question ..what if we have database and web server both on same machine.will it be useful to use redis cache or we can make direct call because server and database are on same machine?
Still useful, since redis is in-memory so reading from memory is way faster than reading from disk.
make a video on hiding api key with rate limiting using node js
Example with django please
maybe sometime later
How implement radis db server over the web. Like in other server. We are going to call it node.js?
Redis db can be installed on any Linux os
@@mafiacodes I am asking about hosting provider online. Where I will host my server. How to do that? And this can be installed ina ny windows system?
Windows not advisable for redis, you can host on aws or digital ocean on run a docker image on zeet
How can we display cached data from redis into html , res.render() ? Since we have the data stringified before to save it.
Thanks.

I'm getting this error
(node:11248) UnhandledPromiseRejectionWarning: Error: The client is closed
Can anyone help me?
Just add a line of code `client.connect()` below the `const client = ....`
newer redis client 1) returns promises 2) requires explicit open call
Yes I know 🙂
noice
That's so wrong intro. Use caching when data is fetched often. Not when data doesn't change often
A cache's primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer.
In a messaging app or notifications - data is fetched quickly, so should you cache - NO.
