Modern Redis in 40 Minutes | Crash Course 2023

Master modern Redis with a project-based learning approach. We'll explore the most relevant & used data types and set up both a serverful and serverless Redis instance as our Redis playground. You'll learn performance optimizations and later also learn to keep your database requests at a minimum using Redis JSON.

These crash courses over fundamental topics are a blessing, helps me with my own projects

Just in time I plan to build my next app with upstash! Great Content!

[keshavakumar]

For the past 2 weeks I been learning redis through docs and now you droped this gem 💎
You are the most consistent youtuber with such high quality content. Thank you for this tutorial
I wish this was 4-5+ hr long

[thedevnoteyt]

Fantastic tutorial Josh. Can you please make such crash courses on other topics like React Query, tRPC etc ?

[mohitcodeswell]

Ohhh hiii Josh, thanks for the redis course, I was making a stackoverflow clone and needed this very much !

[kleinertraitor]

Great video!
I'd be interested in a follow up for using redis as a cache and then syncing it with a real MySQL database.

Ein ganz kurzer Kurs, der doch sehr gründlich ist!
Also kurz gesagt: toller Kurs!

[DamirSecki]

Josh, thanks for the video... can you please explain in the next video... how can we use this in production?
and how can we sync the redis with our sql or mongo db?

[frazuppi]

I think it would have been better to create the three tags under tags:<tag_1_id> etc and you then have a set or list inside the comment linking the the id of one specific tag

[tomirodriguez]

Excelent video Josh!
I was wondering in which cases would you use redis instead of an actual database? Since the latest is way more powerfull and cheep, is there some edge cases where using redis would be better?
I can't stop comparing the 10k comments / day from upstash against the 1billon read from Planetscale 🤔

Thanks for all the content :) It really helps a lot

[ashimov]

All concise, and right to the point. Great job, Josh. God bless

[hnmss]

Really nice video on a interesting topic!

In the introduction you say you would explain 'when' to use redis but I'm not sure I got it. Would have been great to explain when to use redis over SQL for example.

[retrosynthguy]

Bro, you're the best, I freaking love u dude

[jermunitz]

Another important key type is Streams. I find it useful for multiplayer games and chat apps were the data needs to be streamed in and updates subscribed to. It's like a little Kafka.

Bro, can you make a tutorial on migrating express server to next js or at the very least use express server together with next js, I would greatly appreciate

[testtest-cz]

Very good video, I congratulate you. I ask you a question, suppose I have an application with a mysql database, my app calls an api to query and show products to the user, if I implement you Redis to cache the busquedaby that the api first see if you have stored in cache and if not just then go to query the database, with the first user who enters the app Eedis stored in the server cache and then if another user comes and asks to see the products would be set in that cache even if they are different users? The cache has a time and then it is deleted and the search to the database is done again, right? Thank you very much

[gosnooky]

What would the performance benefits be to using Redis JSON to just store, say, a cached API response as opposed to just stringifying/parsing the standard Redis string response? The JSON has to be marshaled anyways by ioredis. My current use cases don't involve granular edits to nested data. I just store and retrieve the whole thing.

[apteryx]

Yooo, I literally setup upstash/redis in my project yesterday!

[CodeWithMathias]

i prefer to use docker instead of using virtualization in my machine it's more flexible. great video btw

[santiagograviano]

Keep it going champ, you doing it great!
