My fiance left me about a month ago during the hardest time of my life. I let myself be sad for a day then decided I want to work on my purpose which is to become a front-end developer. So far I bought your HTML and CSS course which is phenomenal. Once done going to buy your JavaScript then react course. Thank you so much, you courses have helped through this dark time and I know there is a light at the end of the tunnel!

[@TraversyMedia]

morenokv sorry to hear that friend. Im glad i could help give you something to get your mind off it 😉

[@Frazer227]

Im so sorry man, but these things can happen. I hope you get through all right. Just remember, there are still people out there that love you. By the way, (At the moment) there are plenty of fish in the sea (not if we keep global warming up though) and you'll find the perfect match one day! I hope you make it through!

[@GameMasters825]

Bro theres a lot of people out there dont stay dow, i bougth all courses of Brad, i told you worth it, but after all courses you need make your own projects, wich you will really learn code, dont miss your faith

[@suyasrivastv]

there are lot of people who dont have a fiance so cheer up

[@zuzukouzina-original]

I think you should be thankful to her. She saved you from wasting you with miserable time. You’re unchained now come on dude. There are plenty women out there, but don’t look for Kardashians kind of women, but hard working women who knows the value of life.

[@UnknownEntity606]

All these years later, this video still stands as a simple introduction to redis. It's instructive and straight to the point. Thanks for the quality content.

[@rgonzy2124]

thanks, I'm hesitant to watch it and saw that the date is 4yrs ago. but I saw this reply and watch it anyway.

[@markmansur9268]

I was literally wondering how to do EXACTLY this a few days ago for my mobile app backend. Thanks again Brad!

[@Mar2431]

Thanks again Brad for this quick course on Redis Caching. I've just recently finished your Udemy course React Front To Back 2019 it was perfect! You provide great learning resources and tutorials to this community of web developers. Thank you!!!

[@maagu-_-]

I cannot thank you enough for these courses/lessons. You are a phenomenal teacher, Brad! These KZbin lessons led me to your Udemy courses which I'm happily buying. Keep it up 😀

[@srcmake]

Amazing video as usual, Brad. Your example server was concise and showed exactly what was needed to demo redis. And honestly, I didn't think to use middleware to check for the cached result and end the response early. That's a 200 IQ play. (I probably would have put the cache check in the same endpoint right before making the fetch call, which is clearly suboptimal.) Thanks for the video! I really learned quite a bit, and I've interviewed with some big companies that do use Redis so it is an important skill.

[@charliebewsey6872]

Just bought your udemy course after watching a couple of your free videos - I've been really impressed with you as a teacher, I hope that the money you get from doing this stuff justifies the time you must spend doing this! It's a real pleasure to support you, I'm sure I'll be buying your javascript course next!

[@johnnycakez2750]

Currently working through the express section of your react front to back course, this is a neat little bonus. I don't know how you do it but your timing is always perfect!

[@codesmart9044]

perfect timing with perfect to the point clear cut explanation ... if you are not in youtube maybe i never doing software development. thanks man... great help from you as always.

[@kanaanbahmani5062]

Thank you Brad you always upload things that people need the most, with the best timing. Thank you my man, you're a great man.

[@yitzchaksviridyuk932]

Went through 3 of your Redis videos today. Crash course, user management app, and just finished this video. Gotta say it's helped a lot. I keep saying this, but thanks again for the video!

[@pavlovicjosip]

Yesterday i was like thinking "hmm how should i implement cache in node.js?" and of course when i get home from the work, you uploaded this video. Thank you Brad, you are the best ! :)

[@Melvin420x12]

I come from your videos out 2017 and wow the change in videoquality is insane! You've made huge progress

[@Battery64121]

Excellent video. You have a good way of breaking technologies into simple practical parts that I can immediately see using in the real world. I thought getting started with Redis would be so much more complicated!

[@CoryTheSimmons]

Really great tutorial. Short, simple, explained the concept well enough to get me really interested in learning more.

[@sharad_1992]

Thanks for the quick overview of redis. I like the network part in the video. It really defines the benefits of redis cache.

[@saranshmamtakhetarpaul6798]

Thank you so much for giving a much clearer picture of Redis :)

[@freddyhaug9379]

This is such a well done video, you can watch in in 2x speed and complete understand everything. Someone can watch this and become a fullstack developer in 7 minutes

[@vaibhavnadgonde4397]

Always pleasure watching your videos. thx again brad

[@haroldcrane1595]

You read my mind!! Just started learning redis yesterday. thanks bro!

[@alibarznji2000]

You're a big help, anytime I want to learn something new, you come to the rescue. Thanks

[@causecaos]

Awesome stuff, I have always kept away from Redis but this is something else. Thanks, Brad

[@indiansoftwareengineer4899]

Thanks, I loved your channel. but I haven't finished with the video, but before that I gave like and then started.

[@HackerWulf]

Love this tutorial. Easily explained! Thank you.

[@dev-qq2vy]

Redis becomes very easy to understand with your presentation. Thanks.

[@zvuk]

This is not a video that i need, but still ... i let it play, and give it a like and comment this just to support you. This channel deserves it. I do not do such things on any other channel.

[@jorkhachatryan317]

Hello Brad, you are my hero-instructor, because you always creating very useful content at right time(for me). Will be great to see Kubernetes course. Thank you very much you're the best!!!!

[@M1rot1c]

well explained! i'd love to see more advanced usage of redis next

[@khalidelgazzar]

Superb tutorial. Short & sweet. Thank you!

[@smsibasish]

Exactly what I was looking for. Thanks brad :)

[@tomosterlund6497]

Thank you Sir! Always thought that caching was something really tricky, until now. Managed to push down waiting time on a few of my slowest requests with ~40-50%, in production, in the project I'm working on right now :)

[@klarnorbert]

It's tricky, if you write a library yourself. Js community is so big, there's a solution for everything.

[@AmitYadav-el5wg]

Awesome tutorial, i think one of the best tutorial on redis in node. Thank you 😊

[@larissarosa5863]

As always, a greate video! Thank you very much! I was able to apply pretty much everything with Python. Awesome.

[@augustinekanyi]

aah Mr Brad! nice to watch your videos in the afternoon!

[@atmospheric_b]

Yes! Thats one exactly what i needed! Thanks Brad!

[@SuperJAIMISH]

Simple and concise! Great tutorial.

[@ecommerceuk]

Excellent tutorial. Concise and totally aligns with the title. Strangely, 7 people have hit the thumb down. Is there another country where thumb down means good? No other obvious explanation.

[@nandinaulfaldy9132]

Thanks your course and everything is always helping me, can't wait to buy your next course

[@hroland]

Was just watching your 2017 tutorial when I spotted you uploaded an updated one! :) Much appreciated!

[@umamaheshmeka1032]

Nice one brad, thanks for making it look so easy. by the way I had to do `redis-server` first and then `redis-cli` in my Mac Mojave.

[@surajdutta5730]

Awesome tutorial. Just what I wanted to learn today 👏

[@zuhrulanam5971]

Woahhh. Thanks for this gold tutorial, very clear and understand

[@talalnajam8692]

I can't believe how you make programming look so simple and understandable. Excellent video as always :)

[@PrashanthPuranik]

Thanks Brad for the great intro to using Redis with Node. I noticed small typo at 5:28 - it should have been something like process.env.REDIS_PORT || 6379 and not process.env.PORT || 6379. Wanted to document here as a comment for welfare of anyone setting up a PORT environment variable only and wondering why the script wouldn't run. EDIT ------- Also app.listen( PORT, ... ) would be required.

[@usmankhan-tm2iw]

Thanks. You made redis so easy.

[@nidhishetty1225]

Thank you so much for sharing your knowledge:-)

[@sam_mitschiro]

As someone who uses redis in production, both as a queue and cache, i can confirm that redis is powerful.

[@colonizatorgg5960]

hey, can you give your github?

[@tingtingzhou9508]

Such a useful video! looking forward to more!

super helpful.. thanks brad

[@neenus]

Brad as always very informative easy to understand tutorial .... my one question to you and is definitely off topic... but I love how your browser new tab starts with this customized page and I've created something similar to it but couldn't figure out how to customize my chrome browser to start with it would you mind sharing how you did it! it seems like you're using Chrome browser if it is how did you customize the new tab to start like that I couldn't find anything in the settings that lets new tab start with a customized page?? thank you!!

[@pankaj_9998]

As always very useful. Thanks

[@yashtibrewal4259]

Informative, Thank you. Just one question, I like your speed to code while you are explaining, so how many years of coding experience do you have (non-industry and industry)?

[@MERNStack]

yes it seems so useful and fast up the site

[@batsaikhanorgil9153]

Great,Thanks for diverse topic, Can make content about jest and ezyme

[@Qwerter1410]

Great video!

[@buyandelgerbatsaikhan1202]

Good one! Thanks!

[@argahutama]

So useful, thanks

[@lukehero]

Would love to see something like multiple user sessions with this.

[@Geomaverick124]

I think i may implement Redis in one of my portfolio projects once they are finished. Would you suggest Redis for CRUD apps or Fullstack apps or just for client websites...When do you think adding Redis can become over kill?

[@Ghaleon]

Hi ! What font do you use? it's rounded and so nice to my eyes

[@sleeptil3]

FYI if you're getting the node-fetch ES Module error its because newer node-fetch only supports import. You can either downgrade node-fetch to 2.6.1 to use require() or add "type": "module" to the package.json and use 'import' (for everything) instead of 'require'

[@ShivaKumar-st9ps]

You may not needed node-fetch anymore. In the latest version of Node.js (18.0.0), global fetch (experimental) is enabled by default.

[@munapadhi8723]

thanks brad .

[@kavindesivalli]

Great Video... I have a doubt. what if the number of repositories of the user has changed?

[@ramprasath25]

Kudos man Cheers..

[@microvirus]

Thank you so much

[@vittoriodeluca5233]

Awesome video Brad. What about making a NginX or varnish video?

[@MaheshKumar-lq1xm]

That was awesome

[@bicanmarianvaleriu5400]

Based on your experience for server caching a node app, do you recommend lru-cache or this method ?

[@NicoAntoniw]

Hey brad, could you make a video about a node.js headless cms ??

[@TraversyMedia]

Yes definitely at some point

[@ashiqsultanmohamed9765]

Please make one, a tutorial on Strapi will be great.

[@eugenevedensky6071]

Interesting! So this is coaching implemented on an api layer using redis. Now, is it viable to implement a similar strategy using local/session storage in the client if user data remains relatively unchanged throughout the day?

[@juhandvan]

thanks a million

[@divyagowda836]

Hey Brad, one question on redis is which all calls we should usually cache. I'm building a LMS and planning to use redis so is it good idea to cache all api calls or just courses related api? Any insight is very much helpful.

[@novailoveyou]

Thanks!!

[@ighsight]

Excellent.

[@leonesouza8410]

hi brad, can make some video about how deploy a nodejs docker container? thanks man

[@claytonvanderhaar3772]

Awesome thanks

[@cobrassasino]

Thanks a lot Brad for this video. I tried many to watch videos and understand Redis. I still can't see the purpose of this! :( When Redis is useful?

[@ashafloki]

Thanks a lot
