Type of "CSV" files not recognize about angular-file HOT 3 CLOSED

It is the browser that reveals the mime type. Standards exists for how the whole reading of files goes in a browser. This package, angular-file, essentially wraps all the adhering of standards for browser file reading into an Angular package.

For the mime type, this package, just takes what the browser gives it during select/drag/drop and then it does it's best to see if mime types match occurs as follows:

1. This package tries an exact mime match as seen in this code:

• https://github.com/AckerApple/angular-file/blob/development/src/file-upload/fileTools.ts#L22

2. This package tries to match by file extension as seen in this code:

• https://github.com/AckerApple/angular-file/blob/development/src/file-upload/fileTools.ts#L28

All of the above mentioned mime type comparing and parsing, is unit tested in this code here:
https://github.com/AckerApple/angular-file/blob/development/src/file-upload/fileTools.spec.ts

Please let me know if you have additional input, see a mime type comparison issue, love pinball, or let me know anything else I can help with

"Or am I missing something ?"

Yes, that is correct.

Are you using Internet Explorer or Internet Edge? As I last came to understand, during drag drop they don't reveal a files mime type. I've seen a few browsers that think it's a security risk to reveal any file information about a file during drag just incase the drag/drop is not intended for whats being dragged over.

So try, instead of drag/drop, selecting files and see if you get the results you desire.

Lastly, this package does NOT keep any mime type listings. It's up to you to type in the correct mime type. I've seen CSV as many things including text/comma-separated-values. Files can even be written with no mime type and then its up to the code to decide to assume the file extension is the right type.

Mime typing is a long a vast story. I recommend using more star like validations such as image/* or text/*

Good luck to you

Thanks for the answer

No, I use Firefox..

Maybe you answered to this and I didn't get it but I have one last question to clarify my thoughts...
Who determine the file type (see picture) when they are dragged or selected ? Is it your composant (angular-file) or the browser ?

Thanks again :)
