How do I create file with json inside?

I'm trying to create a new File() and write json to it but I Don't really understand how to. I've looked at the documentation but I don't understand what BlobPart is.

When I tried this:

const file = new File(this.myFrom.getRawValue(), 'json');

I got error :

Failed to construct 'File': The object must have a callable @@iterator property.

I need to append the file to formData like this:

formData.append('file', file);

You're nearly right. You just need to

a) put the content inside an array, as per the documentation

b) set the content type through the options

This is the corrected version of the code:

const file = new File([JSON.stringify(this.configForm.getRawValue())], 'payapp_init_json.json', {type: 'application/json'});
