Socket.io Introduction - How to Build a Chat App

[@adelprog]

First, thanks for this tutorial. - In recent versions of Node.js, we don't need any extra packages to monitor file changes (like nodemon), We can simply add the flag "--watch". - Even on the same server, using different ports for the frontend and backend will result in CORS errors.

[@DaveGrayTeachesCode]

Yes that is with version 20.6 and up I believe. It has not reached long-term support version as of this video or this post. I'm sure it will soon.

[@akintobby]

​​@@DaveGrayTeachesCodeyes that's. The --watch flag is an experimental feature on node v.18

[@dustchenai]

Good job,thanks Dave,and I am from China,I hope more and more developers in China could have access to your demonstrations if there is no Great Fire Wall.

[@kirolosmahfouz9173]

during the series enhance styles and it will be great if you use database to store messages and convert frontend to react it will be awesome

[@rishabhmehrotra6976]

Amazing Tutorials Sir. You have changed my entire vision and interest.

[@deniserodriguez3233]

Holy shishkabob, just in time too. Thank you!

[@biLLie_wiLLie]

Thank you Dave! I'm waiting for nest js course. Even if it's paid

[@AjithKumarsham]

Great content!! Looking forward for socket series. Thanks!

[@عثمانصالح-ه1ر]

Thank you so much I'm really appreciate that you work hard to give us this informations 💛 🙏 💓 💗

Just found out you are getting married Congratulations 🎉🎉👏 👏 for your marriage 🥳💕 in advance

[@svetoslavtrifonov6431]

Great video. I hope you will show us uploading files (images, docs , etc) and storing them. Also it would be great to have chat history with room or person, what are the best practices to store the history and user settings in some db :). What are other scenarios to use web sockets, what else are they good for (shops, warehouse inventory or something like that). Thank you for the video

[@replicant9611]

I really like this kind of comments. Each time Dave or any other tutor on KZbin posts a video, there's a request to build a full-fledged app with any esoteric requirements that can even come up into one's head. They just give yout essential concepts how things work. If you are software engineer, you should figure out yourself how to upload files and add chat history feature.

[@svetoslavtrifonov6431]

hmmm I thought part of the tutorials is to give the esentials or more common things, but hey ok if he make a video about this I urge you not to watch it. I really like Dave videos and it is up to him what he will show us and what is not worth it, not you or anyone else. If you are his agent and he gave you a task to speak for himself its ok I rearly comment anyway. Be well mr. Pro software engineer

[@davidhusted817]

[@TRENDINGTECHSCHANNEL]

why live data sometime slow the performance of browser..which points to keep in mind when using socket io

[@mikelautensack7351]

Can you do a video on how to use socket io with next 13 app router?

[@basiccoder2166]

Fantastic

[@tetyanagon3342]

TY!

[@joyustcian222]

Thanks a lot

[@mrbilchalan]

So, in this case, it always established connection with socket server when you open the chat app? But if it needed user authentication then after authentication it establish connection, right? Sorry if my questions seems funny. Always love you.♥

[@DaveGrayTeachesCode]

Yes, you would create the connection after authentication

[@ghassanclassic7689]

Thank you very much Dave 🙏

[@mdkawsarislamyeasin4040]

Uhu, I have been searching this kind of video (latest) Now got it.

[@leojohn6702]

Many thanks. Btw, is it possible to establish a ws connection via an express route? So if I am doing a chat app, it wont be fully web socket, but express?

[@DaveGrayTeachesCode]

You can use Express with sockets and I will in the next tutorial. It won't use an express route though. The socket server just listens for a connection.

[@waseemusman421]

great

[@VinayakSoni98]

Let's write more code together. Sir

[@xXxAtkinsxXx]

When i type a message it outputs the dynamic key but the value is {data} I9SkH: {data} anyone have any ideas as to why it is different when the code is the same?

[@xXxAtkinsxXx]

nvm... found the bug... missed a $ on my string interpolation

[@VinayakSoni98]

would love to see scylladb/cassandra/ mongodb integration. with redis and other technologies.
