dude ur like the only person in this entire bloody internet who actually explained this properly
Legendary comment😭😭
As a teacher, I can say this is mindblowingly brilliant! Oh man the effort that gets in producing a seamless and well constructed lesson like this is enormous. A massive thank you from me.
Ahh, it's finally here! Thank you Mr. Shiffman for everything that you do!
if only you'd have started this series about 4 years ago, it would have made my life back then so much easier!
Finally got to understand it properly :)
Due to your pavlovian training with the bell, I now smile every time I your videos start Shiff. Excellent as always.
You are the god of programming tutorials. Your excitement and joy is contagious. If there was a person who could give birth to webDevs it's you. 😁👍🏻
This is the type of content that pushes humanity forward. Thank you for empowering others.
Just in case you confused like I was- "rainbow.jpg" is a file on his computer, so you just navigate to an image on your computer too.
Thank you!!!
the thing is for me the fetch API cannot load. i just did what was written by Dan.
the console said:
URL scheme must be "http" or "https" for CORS request.
oh ok it is done when i started the live server. i forgot that one
but where do we define the path for that file?
@@laalaajonsen
"rainbow.jpeg" is a relative path
Liveserver does load all the workspace (project folder ) on the network!
So suppose that that the project folder is:
Project ( index.html, img[ rainbow.jpeg ] ).
Fetch with absolute path is like : "localhost:5500/img/rainbow.jpeg"
Or with relative path is like:
"Img/rainbow.jpeg"
Such a great teacher, not even fully into the series and I can already tell I'm in good hands 👍
I am finally able and happy to report that I was able to write code to fetch an array of images and put them in a web page. I was also succesful to fetch the text in a .txt file. I have a good understanding of HTML and CSS and a few weeks of learning Javascript, so my next goal is to construct a web page to display analytic and historic information of Formula 1. There are a couple of API's available that I can use, so wish me luck!
Did you succeed? Post a link to the live page if so!
Wow! Amazing the way you explain how the code actually works behind the scene instead of just showing it. That is real teaching!
Respect from Brazil!
Seriously man. This is the best tutorial training I have ever seen in UA-cam so far. I'd love the way you teach, explain and illustrate. You're really doing great stuff. Thanks a lot.
Would you happen to know what does 'img elt' means at the 8:55 mark ?? I've never heard of " ELT " before. Thanks a lot.
where to get the rainbow file from ? where is this server please I am new to this
@@omkarpabe7780 it could be any file off the internet or stored locally. In this case he's using an image off the internet that has the .jpg extension.
As I am new in Javascript, but this guy could deliver precise explanation about it. Subscribe is a must !
I am massively appreciative for everything that you are bringing to the table in this course, as well as by way of all the other resources you provide. God bless you man.
I like how he made everything fun, even a person with no programming background can understand his explanation... I wish they taught me this way from the start
After like 5 other walkthroughs that left me feeling stupid I'm realizing how poorly almost everyone else explains this stuff. Props to you for being a good teacher. Thank you.
Wow.. this tutorial is perfect to context which gives real world example. Thank you very much.
probably one of the best programming teachers.
just came across your youtube videos, you have the most fun and vibrant coding lessons, and a teacher all children should have!
How does it happen that whenever I am stuck at anything and cannot think of any solution at all, you just completely solve my problem and make me a happy person again. ❤
the magic of FETCH-ing starts from 11:18 ASYNC & AWAIT --- awesome
i always head straight to your videos on any topics i learn, because of the way you explain and energize me. I am literally happy while watching your vids!
The best possible explanation that is available on UA-cam 👍👍
I absolutely love your tutorials. I'm astounded by how quickly you cover the information, jumping into code, error fixing, and rambling over so much territory with joy and humor. Math homework has never been this much fun!
I feel like I am there in the class. I get him and what he is saying so well. Learning just got easier for me.
You are my code hero. Nobody explains so easily like you. Choo choo !
I just love how he reminds me of my 6th grade teacher, like he literally has that same enthusiasm! Makes me really want to learn JS. Such an awesome job at keeping your viewers attention. I kinda wander off when learning on my own lol
Been coding in C the past couple months can’t wait to come back to JavaScript.
I'll be here!
You are so good at explaining everything! Thank you for the video :)
one of the best video to explain js in the most simple way.
I am new here and i came here to learn about api and i am damn sure that i will definitely learn too much from you Sir
VS Code has got an extension that is also called Live Server. It does basically the same thing, but for someone that has not yet played with node it might be simpler to use.
@@creeplabs idk about raspberry, but at least for linux distros, search for nvm (Node Version Manager)!
@@creeplabs Installing node in linux under sudo is going to create lots of permission issues
just install it as a snap then > snapcraft.io/node
@@matrezak it's only you put --unsafe-perm at the end of the line.
sudo npm i -g node@latest --unsafe-perm
xD
sudo apt install npm && sudo npm i -g npm@latest && sudo npm i -g node@latest --unsafe-perm
i'm glad to know english, just to say: thank you for all effort put on those videos.
i have never enjoyed while learning something. You are soooo good in explaining stuffs.
I finally understood fetch, in a way that I won't forget in 30 minutes. Great video!
This stuff wasn't really setting right with me before. You helped me figure it click for me but that wasn't the best part of the video. You make it fun. Life doesn't have to be boring, why not make it fun? Thanks a ton!
One of the best coding channels out there. Amazing video Shiffman, thank you for it!
Just the perfect course for my project. It's due on Tomorrow, hope I can complete it. This course has made my work much easier.
Hope it went well! :D
lmao same reason i'm here too
This is soo informative and well done! I love your enthusiastic voice tone. I can't thank you enough. 👍🏽👍🏽👍🏽👍🏽👍🏽
This is a BRILLIANT lesson! Its very good. Thank you
even adds async/await in first video this guy is the internets end boss. good work.
WHY DIDN'T I FOUND YOUR CHANNEL EARLIER! SUBSCRIBED!
Thanks for the amazing contents!
You're content is so awesome. I'm going to join NYU as a grad student in Bioinformatics and am proud to be in the same institution as you.
Come say hi at ITP!
I like the happy energy you deliver so coding is less depressing :) thank you !
Really like your style of teaching. You simplify concepts to the basic.
Awesome lecture. I'm jobless at the moment, but I will subscribe to your channel as soon as I get a new job.
You are my favorite teacher because you are so fun to watch so happy and animated thank you so much :)
This is the first video of yours I've stumbled on and it's the best yet to break down fetch() with the added bonus of await/async. I'm a self-taught adult student and it's hard finding a teacher that clicks. Subscribed and looking forward to diving into the rest of your videos.
i'm sorry, but the n00b in me has to say it loud... so here comes the CAPS:
"IT'S BEEN DAAAAAYZ I AM STRUGGLING ON GETTING A SIMPLE API CALL TO JUST WORK AND LITERALLY NOBODY BUT CODING TRAIN TOOK THE TIME TO EXPLAIN & DEMONSTRATE IT IN A PRACTICAL MANNER (..and with such enthusiasm!) ! I FINALLY UNDERSTAND HOW IT WORKS! ALERT("THANK YOU SO SO MUCH!!
I feel happy while studying from you.
ur a god, beem strugling with fetch for a week, its easy to understand u
Glad to hear!
Amazing ! Just discovered this channel because I was looking for how to use fetch and async, I understood all that stuff in this video. Thanks !
What a fantastic teacher! Keep up the good work
Man what did we do to deserve a teacher like you❤️
Thank you for the video! You made it easy to understand. I will try these exercises you suggested at the end of the video.
The only tutorial that made sense. Life saver!
Thanks for this video man, and grateful for google for linking it as 3rd option for beginners looking for practical fetch API lessons.👍
The first time I really understand promises! LIKE!
The best content and teaching method i ever seen. Thanks
Excellent - thanks! Just subscribed and will be watching some more videos related to fetch and async await.
Im showing this playlist to EVERYBODY! Congrats on the effort because this is helping me out a lot!
Working with fetch and .then in my bootcamp. This helped me tremendously thank you so much
The exercises in the final part are really good! I used other API called dummyjson to put a random quote with the author of the quote in the page. Each time i reload the page is a different quote.
i never really understood how to use api until i watched ur vid .
Thank you, this concept is not easy to understand, but you explains it so clear that everybody can understand it now. Thank you for your effort and sharing.
Basic concepts explained in an amazing way. Thank you once again for the great content and way of presenting it to the youtubers. You boosted my knowledge more than a whole semester at uni. Stay safe.
This guy is awesome, Wish there was more time in the day to watch all his videos
I love you. I have been searching for an easy way to retrieve an image from API and everyone was converting it into a base64 text. This si much easier, thanks !
Bro, you are a lifesaver, thank you so much for the well delivered tutorial. You've provided the full context, focused on the function clearly, and chunked up the steps involved in an understandable and logical manner, which is really important for true comprehension.
You and your channel are *brilliant*
That was nice. I`ve seen no teacher as jolly as you. Thanks for the video :)
Hey, do you know what the three calls to fetch() are?
To be honest I'm amazed I was able to do it! I sort of followed along while you were explaining the await and blob concepts but I actually managed to get three rainbow images to display plus the text. Woo!
Was coding along and I too kept on mispelling response too! Ahhh! Great tutorial. I enjoyed the challenge at the end which pushed me to make sure I understand how this all works! Looking forward to the rest!
U r a genius and teaches with heart. What else can we need?...Alll happiness
you did really well. You said what we needed exactly.
You've mentioned "arraybuffer" at some point during the video. And I'd like a video with raw binary data manipulation and/or typed arrays. It is truly one of my dream videos that I would want to see!
Thanks 🙏 I really like your videos , your energy and the way you explain in front of the whiteboard. I feel like exactly in the class 💫👌
I've been looking for this for a very long time!
You're alright buddy... good vibes and its genuine
Your tutorials are super duper awesome Mr. Shiffman. I'm learning and loving your contents. Keep it up
You're a magician. You really found your vocation!
Thank you, I had to scout a few videos with different teaching approaches and after 1-2 'explainer' videos and some stackoverflow posts I still didn't get "fetch" - putting it on whiteboard and the 'promise' aspect of the response really clinched the function for me. Thanks!
I enjoy your videos so much. This is so related to what im building and the way you explain things are very good. You enunciate and even the tempo is a bit faster its not that hard to follow. I appreciate you! 😘
Finally some high quality tutorial, thanks dude
This content and tutos are just, GOLD!
Nice video Dan :). One thing people often forget to do with fetch is to also look at the response! HTTP-level errors (eg: 404) are still considered resolutions, and so we're assuming that the response we get is fine to work with even though we may have ran into a HTTP-level error. A fix for this is to add a quick if-statement in the first _.then()_ callback:
.then(response => {
if(!response.ok) { // check for HTTP level errors, throw if error occurred
throw new Error("Failed with HTTP code " +response.status); // reject
}
return response;
}).then(result => result.blob()).then(...
This way, any proceeding code/logic can assume that the response received is okay to work with.
Thanks again for the videos, can't wait to see more :)
Oh, this is such a good tip, thank you!!
"I'm going to make an error happen just so we can see it"
That's my secret Cap, I always have errors in my code.
Dude you are amazing!! Fantastic video!
I just want to say, you are the best.
A massive thanks from here for your instructive lessons and your effort you're putting in this!
Bow!
You are the best teacher ever! Thank you so much for your videos! ❤️
for people who is having trouble to define the path, first try to open the image using normally path on HTML tag page egs:
Very interesting,learning with you.🌷
Good fetch tutorial thanks. I have a question, Can I use fetch in combination with setInterval? The thing is that I have a json file that update every 10 seconds, and I need get the current data, to print in the html and handle the same data to do another stuff. What do you recommend to me?
Hey King, you dropped this 👑
Thanks a lot for your efforts, you really make it seems to easy
Exceptionally explained! Thanks
Thank you for the videos!! so i managed to do the Fetch() API successfully . I now want to pass the SRC with the encrypted payload to a browser . How can i achive that please assist ?
I love your videos dude, can't wait to go through this series!
The best teacher! Thanks for your awesome work
