Man I love it, I think a lot of us will really appreciate a project done using this framework.

[@pateldeep93]

I was literally googling about this yesterday... Thanks for video.

[@EmmanuelMkansi]

Brad, you're so awesome, always short and very straight to the point. Keep up the good work.

[@gregorytippett9692]

Even if I didn't code I would still listen to Brad's tuts because his voice is so chill.

[@dumbfoundtown]

Thank you, wonderful video with some good explanations / context. I want to learn node and backend and will use Koa on my job so this helped me ingrain some knowledge about it. Keep it up!

[@YaserAz]

Hi Brad. I was really impressed by your tutorials and especially the 'MERN Full Stack' on Udemy! That was a leftover for me. It really helped me comprehend the overall concept . Hope to see another advanced one like it from you . Love you man! keep in coming :D

[@nimasab2377]

Brad you’re just freaking awesome 👍👍👍 you’ve helped me like a thousand times. I can’t thank you enough. God bless you

[@dejson420]

[@xristianmatos]

Excellent tutorial, I learned a lot with it.

[@Mohammad-vv5ef]

Hey Brad, thanks for your awesome and impressive crash courses. Please create a playlist of Python courses because I'm following web development according to your instructions.😁

[@terry6180]

Big big thanks. .....love its all your videos....

[@javierlizarazu7680]

Awesome tut as always. Thx bro

[@sexyeur]

Love the video. Thank you! You're choosing Koa for what reasons? Do any of these frameworks have any particular application or advantages that make them preferable to others?

[@bradical8198]

Jesus Christ.. of coarse you have a video on this, video on erythang! FANTASTIC BRAD!

[@AlexanderSuraphel]

Awesome overview! It would have been nice if you added a simple auth flow( maybe basic auth). That would give a taste of the framework for someone trying explore.

[@viveks289]

Thanks a lot for your efforts.

[@ClassicCartoonsNL]

Thank you for this video!!!

[@mukundhbhushan6709]

Suprb work bred!

[@praweewongsa]

thank you. i love it.

[@knightonhd1144]

Nice One, Thanks Brad

[@quebirt]

Another great video. Thank you. Koa looks like something that I could get into if I weren't so tired of javascript. I like the minimalist approach, and faith in the Express guys is a given. Hoping I don't sound like I believe I own your time, but I hope you haven't been sidetracked from the Golang-web front.

[@hassanali-yi4bu]

Why would you be tired of javascript? Its an amazing language, read the book "you dont know JS" to really learn javascript

[@TheCodePro]

Hey, awesome video Brad! Just wanted to take a minute and say that you're a real BEAST for creating this much content on your channel. We really appreciate the amount of time you put into these videos. You're a real inspiration!

[@AndreiNedelus]

Hello, i really enjoy your tutorials, is it possible to make a tutorial on how to use touch events listeners in a web app For example swipe from left to right and open the menu.

[@dev.syedmh]

your accent, like your content, is great :)

[@elhadjbabacarcisse2868]

Thanks Brad!

[@wilgen6827]

Amazing!

[@kentsang3786]

Awesome videos dude

[@ChaosEmerald85]

quick solution for a problem I ran into: if you're getting an undefined object returned from the body, make sure you put app.use('bodyParser') BEFORE the app.use statement for the router

[@overnightmares]

Brad hi, do you have any plans to make a (udemy) course about React Native? There are not so many and I'm really liking your teaching style. I hope you release a comprehensive react native course with making a full stack application with authentication , maps, camera app etc.

[@TraversyMedia]

ofisboy its on my top 5 list most definitely. CAnt say when though

[@daysnight2871]

NativeScript?

[@overnightmares]

Traversy Media great news! looking forward to it! I hope you also cover ejecting and using 3rd party libraries inside the ios/android projects.

[@naspy971]

almost 500,000, hoping a special video about it

[@CopyPasteYoyoTricksTutorials]

Great crash course! Can you make crash course to node.js scheduler jobs like agenda?

[@adace1]

Hey Brad, could you make a tutorial on async/await in Python? Thanks.

[@seankaila]

hi. ive got a slight problem. followed your tutorial its great. However when i run a post route using a button. The program would run multiple times, then even run buttons that havent been clicked. Any idea why?

[@satyasaadhak]

I'm not even remotely close to it right now, but at some point I'd like to create my own published modules for some things I have in mind. Do you have anything of that sort in pipeline? If not, could you please consider it?

[@satyajeetkumarjha1482]

Hey Brad, Can you make one video where you dig into the source code of frameworks say of express etc?

[@greggsworld4453]

that would be epic!!

[@giftedfingers2580]

I literally got out of bed to watch this video.

[@basheeral-momani2032]

20:49 , people who are watching in 2023 for bootstrap 5 you should use ms-auto

[@varaprasadreddy6420]

Please make a video on NODE-RESTFUL

[@Julia_Berrrlin]

@brad I'd appreciate an update to this especially vs nest.js Is koa still the best

[@forzaforza9204]

Any of you heart of Nests? Nodejs framework is built with TypeScript (preserves compatibility with pure JavaScript) and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming). Let me know what do you think of using TypeScript in the back-end.

[@HansHeidman]

Commands used in this video: - npm init -Y - npm i koa - npm i -D nodemon - touch app.js (creates a file called app.js) - npm start - npm i koa-json - npm i koa-router - npm i koa-ejs - npm i koa-bodyparser

[@denniszenanywhere]

Can you do a tutorial on Solidity using JS and remix in ethereum? Thanks

[@nicolasrozenberg5209]

.

[@xpaiinz8250]

Would you choose Koa over Express in any case?

[@greddee]

Yes, Koa includes less of the built in stuff that Express provides. So if you want full control over your app, Koa could be a better solution.

[@xpaiinz8250]

@@greddee so I guess there are no reasonable cases to use express anymore?

[@greddee]

@@xpaiinz8250 Well... It depends, if the project needs features that Express has then Express is a better alternative. Also, if you're simply developing an MVP, Express allows you to get results quicker because you don't need to spend as much time on customization.

[@fransiscowijaya]

Please add modularity, poluting app.js is messy. I don't know how to module Koa. End up with Not found ctx.

[@razvacos7469]

Mobx crash course please

[@mylastore]

I love KOA, but I can't find anything on how to set cookies from a KOA API to a Svelkit front end. The following code does not work. I see the cookie on the response headers but does not set on the browser. Can you help? or Do you have a Koa course where you use cookies and JWT tokes? class UserController { async login(ctx) { ctx.cookies.set('token', authUser.token, { maxAge: 12000, expiresIn: sessionExpiration, sameSite: 'none', httpOnly: false, secure: !isDev }) } } export default UserController

[@mylastore]

I figure the above for some reason, KOA only sets cookies with secure: true. Therefore, I installed SSL and ran dev ENV with HTTPS, which worked for me.

[@FunIsGoingOn]

I was watching the part with "Add Thing" five times and it still didn't worked. Then realized the window was too small, maximized it and there it is. ^^

[@Albertmars32]

Mobx pleasee

[@AaronTheImposter]

Do you have a Slack or Discord for the community?

[@TraversyMedia]

CodePapi i turned my discord server into a general community. Its called the developer hangout discord.gg/developers

[@qazyhn94]

15:15 views is what is used :DDD

[@EnricoPolanski]

I generally like your videos, but here you didn't really explained what is the most important feature of Koa (the cascading downwards and then upwards). There was much more ejs than koa really here.

[@johnnydriesen7575]

Great one Brad... To all down-voters... please be that fair to say "why" you've been down-voting ...

[@OstonCodeCypher]

how to create a sidenav like google adsense

[@mdanilrafiqi]

feathers.js please

[@kresimircosic6158]

Stupid question, but is the require function the same as importing modules with Import XYZ from WTF

[@nadir2k]

Found very few dissimilarities from express

[@andrei8683]

tho Koa is considered several time faster (according to statistics). But agree. Looks almost the same

[@sucess-frame7476]

How hard you stroke that key it's dying

[@sharana2496]

Do a floating nav video.... There is no video clearly..

[@bravenxd0]

Hi

[@JorgeDev92]

Express wth other name

[@jorgeriveramx]

10% Koa, 60% ejs templating, 30% other stuff.... This is not a course on Koa. And koa-json middleware is not making the response prettier, it is making it follow JSON format.

[@tarcus6074]

We need more frameworks which do same shit...Express the best, i don't need this koa crap.

[@underscore4751]

Lol bruh its made by the developers behind express and why do u think they made this they aint stupid my man

[@nromancarcamo]

Bad Ash tell us why? Express has already fixed any error it had.

[@HelloWorld-ut2kl]

Hey I Like Express, Koa, Hapi etc And I personally use Hapi.js it's simple and good
