native-file-system-adapter VS FileSaver.js

If it's larger, it's complicated... https://github.com/jimmywarting/StreamSaver.js generally works, but is not 100% reliable. https://github.com/jimmywarting/native-file-system-adapter is supposed to be like a newer version of it, but I struggled to get it working. You can also use https://web.dev/file-system-access/ but it's only supported in Chrome.

Maintained polyfills exist for the File System Access API right now. "Workarounds" have been a staple of web development forever. PWA also has nothing to do with their concerns for the file system access api.

var headers = new Headers(); headers.append('Content-Type', 'application/x-www-form-urlencoded'); this.http.post('http://localhost/a2/pdf.php', reportPost, { headers: headers }) .retry(3) // .map( (res:any) => res.blob() ) // errors out .subscribe( (dataReceived:any) => { var blob = new Blob([dataReceived._body], {type: 'application/pdf'}); saveAs(blob, "Report.pdf"); }, (err:any) => this.logError(err), () => console.log('Complete') ); ps. the saveAs function comes from here: https://github.com/eligrey/FileSaver.js

You could check out this library to see how it’s done or just use the library itself: Blog on FileSaver.js

As a result, I had to go to the github page for FileSaver.js (https://github.com/eligrey/FileSaver.js), copy the “FileSaver.js” file in the “dist” folder and paste it into a new file in the same directory as my code. The FileSaver.js is then imported using a “script src=” tag on line 6, as seen below

Goto link https://github.com/eligrey/FileSaver.js After opening the link, go to the dist. folder and download FileSaver.js file

By following some post :get_URL().createObjectURL error I was able understand that:

The code of the component function is below. I've tried different alternatives, the blob way should be the way to go as far as I understood, but there is no function createObjectURL in URL. I can't even find the definition of URL in window, but apparently it exists. If I use the FileSaver.js module I get the same error. So I guess this is something that changed recently or is not yet implemented. How can I trigger the file save in A2?

I tested a file-saver.js, but it can only save, not load files, and it can't save in the background, it has to prompt the user to save the file somewhere.

If it's a relatively small amount of data (like 100mb or less), try https://github.com/eligrey/FileSaver.js it handles all the edge cases nicely.
