Can't open .epub file downloaded by FileTransfer

[coelhucas]

well, probably it's some noob mistake but after spending some hours trying to fix it I needed to come here.

   this.fileTransfer.download('https://github.com/janpio/ionic-epubjs/raw/master/src/assets/books/moby-dick.epub', path + 'moby-dick.epub').then(entry => {
      this.finishedDownload = true;
      let url = entry.toURL();
      this.current_book = new Book();
      this.current_book.label = "Moby Dick (.epub)";
      this.current_book.file =  path + 'moby-dick.epub';
    })

which is not working. to make it happen I need to use an already existing local path:

    this.current_book = new Book();
    this.current_book.label = "Moby Dick (.epub)";
    this.current_book.file =  "assets/books/moby-dick.epub";

how can I fix it? I've already tried using as the this.current_book.file: entry.toURL(), path + 'moby-dick.epub', only path... anyone knows what can I do?

In your code:
What is path?
What is url?
Why are you setting url and never using it?

Sorry for the lack of info. Path is the string where the file are going to be downloaded. url returns the URL where can I locate the file, at first I thought that I can use this url as the current_book.file but it also didn't worked. I was trying to do some adaptation of this: https://www.youtube.com/watch?v=kM4cCQn8Bz4

Is the file actually downloaded ad accessible under that "url"? Can you do other stuff with the file?
Can you hardcode a file an use it at

ionic-epubjs/src/pages/book/book.ts

Line 34 in e2cf4dd

this.book = ePub(book.file);

to see if this can handle files from this source?
