Woohoo! Glad you liked it.

[@TomBrockington]

I have never accused anyone of being a bot before....but nobody has every said cloudflare is any good

[@sureshkumargondi4631]

This is too good. More of this please :) Thank you Kristian.

[@v1d300]

First, amazing! Very well made video. Really like that you even managed to quickly cover wrangler and its use with some details about the CLI tool. Thank you. Second, I need to find friends like you have whom I can call to get $100B fund to my silly ideas I would watch that email trigger project.

[@frankdrolet9439]

Absolutely amazing, thanks for that! Keep them coming!

[@ManasMadrecha]

This is a useful video. Can you do one with R2 on worker and it is being used as an assets cdn for images, videos, PDFs, etc.

[@VenkatRamanaDevarakonda]

Please do a video on email triggers as you mentioned. I am trying to build something and the video will be super helpful

[@rtorcato]

can we get a sample of a react server components and cloudflare workers?

I would love to see the ai-email-summarizer!

[@Marcus1074]

Am i the only one here who is lost because I don't want to use the middleware 'hono'? 40 minutes in and I thought I was following a beginners tutorials to start learning Cloudflare Workers, Am I wrong here?

[@kristianfreemantx]

Well, you are learning Workers! As soon as you start managing multiple routes in a Workers function, it becomes easier to manage it with Hono. That's why we suggest it (or a similar routing library like itty-router) for most developers.

[@Marcus1074]

Thank you for your kind reply, i re-read my comment and I definitely sound like i was grumpy. true is i am battling my own demons and frustration kicks in sometimes, i apologize to everyone.

Cloud provider: Let's make a tutorial about how to use our tool and UI Also Cloud provider: Let's completely revamp our tool and UI so it looks different, uses different config and different commands

[@Every-AI]

this is so good, now need an ai agent trained on cloud flare docs

[@yosemitebandit]

What a great video, thanks! I haven't done serverless before (have done a lot of flask projects in the past), but going through the tutorial has been very smooth, I can see building lots of projects on the CF platform.

[@jonathanoberlander5227]

Enabling users to toggle local mode on and off is an excellent UX.

[@mdfaran7150]

I'd love to see the email trigger project that you made. Thank you.

[@bilalmujahid7445]

Thank you Kristain. Tutorials are super awesome. Really loved to listen to you.

[@CloudflareDevelopers]

Glad you like them!

[@zygote846]

Great tutorial,Thank you CF :).We need more on Cloudflare Wokers.

[@RobertMcGovernTarasis]

Cheers for this, and interesting to see Kitty in the wild

[@RebelSyntax]

Are you going to update this tutorial to reflect the change in documents that you reference? Just curious, I am able to follow along, but even the layout of the documentation pages you show have changed, which makes it a bit more of a challenge to follow a beginner toot. Thanks! loving it so far!

[@Deus-lo-Vuilt]

Thank you, we need more tutorials like this to use R2 and others with a web site.

[@ShuklaAbhijeet]

WOW In the morning I saw examples were Hello Rust and re-checking again I got this.

[@sahillalani2]

great tutorial, are there also tutorials for streaming text responses with cloudflare workers?

[@bepstein111]

Hmmm I can't get this to work, downloaded straight from GitHub, I'm getting ""Model input is not valid: missing required input text_input"". Any thoughts on what I might be missing?

[@2u841r]

top notch tutorial, thank you cloudflare, love you.

[@CloudflareDevelopers]

You are very welcome.

[@scotly_emi]

can you do R2 tutorial please

[@RedVelocityTV]

I wish we could access env as easily in Cloudflare pages with Remix. It was such a chore.

[@clevermissfox]

I still can't access my env object with my worker, not sure why yet since on the browser dashboard it says my env variable is set and I should be able to access it in my fetch

[@richardmilton7948]

Great video - thanks so much!

[@CloudflareDevelopers]

You're very welcome!

[@jimshtepa5423]

when are more advanced courses are coming?

[@anoopchandran3267]

The starter project works in local, but after I deploy and open the url, it says "This site can’t be reached".

[@aldoyh]

You guys are amazing and leaders in the industry. The only issue I personally would like to see is the ability to run PHP Code, or Laravel, just imagine the PHP speed and your steel! 🤠

[@litic]

Does anyone have any project ideas I could do using cloudflare workers?

[@philodox13]

I have a question. At 40:00 you create a new Ai() object. If creating new Ai() is very expensive and requires a lot of compute, is it possible to create that object outside of the GET request so you don't have to recreate a new Ai() on every request? I'm asking because I have a similar use case in my app where I need to create an expensive object, but once created, the methods on the object run very quickly. Is this a case for durable-objects offered by Cloudflare? Does this mean my app is stateful if I want a JavaScript objects to persist through requests?

[@djSiMuL]

What font are you using in KiTTy to get that fancy VIM status bar? Beautiful!

[@djSiMuL]

Nevermind, I figured it out. Had to install NeoVim and NVChad.

[@ianjamiesonmusic]

Helpful, thanks

[@aemadrid]

Can you use bun instead of npm?

[@webbae]

great video thank you! is there any good content on implementing libraries that have node dependencies? I've been struggling with node compat errors for some time now...

[@sashka056]

[@marketfinds]

It was good up to Env. The template is a little different now has 'worker-configuration.d.ts' interface Env { } and now has index.ts. const app = new Hono(); // Fails with error message: Type '{ Bindings: Env; }' does not satisfy the constraint 'Env'. Types of property 'Bindings' are incompatible. Type 'Env' is not assignable to type 'Bindings'.

[@biscuithammer]

For instantiating hono, you don't need to write . also the AI bindings can be enabled in the toml file. it works but Typescript still nags though 🤦

[@columkelly99]

You can enable the AI binding in the toml file and then include in your index.ts: type Env = { AI: Ai } const app = new Hono(()

[@enghimanshu]

Amazing tutorial!

[@se7en2021]

Bro how do you import npm libraries and build them during deploy ? Have to change something in toml?

[@kristianfreemantx]

Nope, as long as you're using the default Wrangler set up, we will bundle any external dependencies for you.

[@columkelly99]

The @cloudflare/ai package used here is deprecated but the run command can be called directly from the AI binding as per the updated docs. However, doing this I get the following TypeError: Argument of type '"@cf/thebloke/mistral-7b-instruct-v0.1"' is not assignable to parameter of type 'BaseAiImageToTextModels'. Typescript assumes the wrong overload due to the messages object not being interpreted correctly. I fixed the error by defining messages with the type RoleScopedChatInput[]

[@ashlok_chaudhary]

Thanks bro 👍 You really saved my time.

[@Christianozuruigbo]

how can I get started, it's great

[@jamesgreen311]

I personally have no issue with the zoom, panning or the cursor movement

[@gachecem_yt]

Does this means i can host a full stack nodejs app thro cloudflare workers?

[@yosemitebandit]

would be cool to see the email ingestor + summarizer project 👍👍

[@johalun]

Great tutorial but personally I find the constant zooming and panning very distracting. IMHO, it's better to find a middle ground between zoom level and font size and keep that constant throughout the video. Thanks!

[@davepratt8753]

I'm looking forward to tutorial on using new Python Worker.

[@liorlsa9]

'wrangler 3.67.1' doesn't work properly, I can't start my project even when just after installing the project. Why is that? I used 'npm create cloudflare and follow any instruction. error: X [ERROR] MiniflareCoreError [ERR_RUNTIME_FAILURE]: The Workers runtime failed to start. There is likely additional logging output above. MiniflareCoreError [ERR_RUNTIME_FAILURE]: The Workers runtime failed to start. There is likely additional logging output above.

[@Pspet]

Ah yes, let's use a random third party library to help us write one endpoint. And then spend 15 minutes talking about AI integration. Just what an intro video needs!

[@AndreiGeorgescu-j9p]

I get your point but he taught you how to use cloudflare workers in the first 20 minutes. What else do you want him to do after that Also it's not random, it's what they recommend and use internally

[@golgothatv9888]

The motion blur on the cursor is unnerving.

[@GrantSR]

You also stay a bit too zoomed in while you jump your mouse around the page a lot. The screen barely moves enough to show the tip of the mouse before you zip over somewhere else. That makes it very difficult to follow what you are clicking on. And I am already slowed down to 75%. I'm sure your explanations are good, but I can't tell because you do so many little things that make it hard to follow.
