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!

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!

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.

@muchis 2 года назад

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

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?

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

@satviknema8629 4 года назад

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?

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.

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!!!!!!
