wooow... i think you are the only tutorial on youtube... that actually explains what they are doing, and doesn't waste time building out an entire interface. You actually explain what each line is doing, instead of saying just write this! thank you!
This is the best video about http request together with promise. You know how to illustrate the concept top-down and step-by-step. Thank you! Such a wonderful job！
This video proved to be a lifesaver for me. Your Javascript course on Udemy is awesome and there is so much to explore in it. Keep Up the good work Sir.
i dont mean to be so offtopic but does anybody know of a method to get back into an instagram account? I somehow forgot the account password. I appreciate any help you can offer me
Great video. I watch as many of your tutorials as possible from both here and Udemy. I currently on the journey to be a MEAN stack dev and your work has been extremely helpful. Please continue to create great content.
i am following you on udemy..you are best teacher i have seen ..its like whenever i want to learn something new, i wish you had created tutorials for that..i get an absolute understanding after watching your videos.
legit godly video. I am using ebay find api to make a ecommerce style app and needed this. our axios request went through but CORS did not allow us to work with it. This is great.
Thank you Max. By the way, yes, XHR object is the "old way". It seems to me a bit more complicated than Jquery, Angular or the fetch API way of working the communication between front and backend
in 8:49 you mistyped the 'url' at first, with the 'z' instead of the 'u'. I assume that those two keys are very close to each other in the keyboard you use. What type of keyboard layout do you have?
@@FordExplorer-rm6ew fetch is great for simple async requests and it's built into javascript. For production you might be better off using Axios for all of the built in features.
i used the idea to see how can i validate website if its active or not. but because of CORS error i could not. is there way to do that using the Javascript? thanks
I dont see the point of using promises here? Am i missing something? couldnt we had just returned the response directly? We have the onload method for us. Did you use promises just to make it analogous to using fetch() api?
And then in reality, you don't always direct access to JSON. At my job the reason for this is that the JSON data is dynamically generated. At which point you will have to manually build the http request header and then use a decompression algorithm to get the JSON data on the response header.
how to create an javascript interceptor, that intercept every xmlHttpRequest, and show an alert each time the xmlHttpRequest goes in error or errorCode is != 200?
Hello I am very new to JavaScript and API Automation. My project uses POST APIs with XML request (with input value tags and userid and password) and XML response. and using JEST framework. Can you please help me building a simple test with handling XML request response, Headers, URL, authorization key ?
I'm lost - when I add xhr.setRequestHeader('Content-Type', 'application/json'); I get a "Access to XMLHttpRequest at 'api.......' from origin 'localhost:4200' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values 'localhost:4200, *', but only one is allowed." When I delete the xhr.setRequestHeader bit, I get this error message: "Content type 'text/plain;charset=UTF-8' not supported". So I have to go back to set the headers to read json, right? It's a catch 22!!!!!!
Now that I've been building and deploying applications for some time now... My question really isn't so much about Ajax , libraries , or the xhr object itself, but... More so, *How do these things work in prod?* How can I avoid those icky CORS errors? What is best practice for stuff like that? I see all of these tutorials , and it's like, yeah... that's nice for my local machine... But I'm concerned about prod and others. The duct tape and glue way to avoid it seems to be, to make hybrid php/JS applications on apache and express (2 servers) Or figure out how to connect websockets (to work in prod mind you) Idk, kinda wanna avoid the whole hybrid php/js thing. Or is that just something one has to go through? Surely there are better ways? Idk.
Hi. I have some problems :) I have trying to call from js, like you, into a django-api-rest which is created by me and it s on localhost the same :) i have this error : access has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Nice one! I started back then with XMLHttpRequests, and made a jump later to the fetch API / jQuery's ajax-API. Old-used thing, those XMLHttpRequests, but they remind me of my beginning in web development. I remember a time, when i loaded whole HTML pages via XMLHttpRequests - something i would never do nowadays. But "ich schweife ab" ... - nice video!
im applying for a payment integration on my website and the merchant gave me files to send xml request but im totally confused any helP>>>> ?????????????????????????????
hello my API keeps retruning HTML and so i cant run my search box to call the API do you know how to solve this issue? in your code i get null and so i have to comment out responseType line and then i just get HTML code in the console this is a sample API call gigablast.com/search?format=json&q=Lisa thxz for any help i been trying to solve this myself and online for 3 weeks Lisa does anyone know the fix for this? i followed the code for fetch from david ceccia but i still get only HTML and so i will also get cant parse error < because thats the 1st caracter of an HTML page
Thank you, I am following you very long time and I learnt a lot from your video but my one concept is never clear about promises and async and await. I would like to ask could you please comment here function getData using async, await this will clear my doubt. Thanks you!!!
I don't get why start using recent methods when the whole point of using XMLHttpRequest is to use it in legacy projects where those methods are not available, I think you should've stayed with the traditional way of doing XMLHttpRequest and not introduce promise or async await etc

After a long time , good tutorials on request, thankyou max
Great Max, Can you add a video about CORS options ?
Yes is there one?
I'm in a front end and backend bootcamp and did the javascript classwork for both. Neither explained sending xml requests this well. Thanks man.

Hi, Max.
Thanks a lot for your work, you are the best instructor and teacher I have ever met.
Greetings from Ukraine!
Thanks so much Katerina, greetings from Germany :)
Just what I needed. Thanks a lot Academind. All the broke students thank you :)

Wow, thanks so much for your support and your awesome feedback Hamouda!
Big fan of you, Max. Just started my TH-cam dev channel as well. Thanks a lot for inspiring.
All the best dude
Thank you so much - and good luck for your channel!
@@academind Thanks a lot, Max.
Very thorough! Thank you, Max!
i started javascript 3 months ago and thnx god they come up with the fetch api
this XML is a nightmare to look at
Thanks!
It would be cool to look at CORS correct options, abort/canceling requests
Interesting topic, I agree! I'll write that down as a future idea!
@@academind, please do, Max! Struggling with CORS-related issues myself right now :(
Thanks Max! Cool video, as always!

Nice explanations and examples, so I understood all the material of the video !
Thanks a lot Dimitris!
Amazing, very helpful and simple to understand
Thanks Max, Your contents are very well explained.
Back to the basics :) Thanks. helped me understand the concept of promises.
Happy to read that Moran, thank you!
really great tut man, clear explanations.

Very good instructor! Thank you for sharing your knowledge
Good one! It would be great if you will make more videos about native js

But does fetch work in prod?
How can I use it whilst avoiding SPA frameworks?

i have this error :

you need to download cors package for django using pip and add some code in settings.py middleware to enable policy
