Opening PDF file in new tab angular 4?

One liner solution to open a pdf file in new tab. You just need to have file url and use this function on button click.

window.open(url, '_blank');

From @barbsan idea, I changed the http headers and received a blob and used that to display the blob as pdf using window.open(). It worked.

Here is my sample code.

In service file

downloadPDF(url): any {
    const options = { responseType: ResponseContentType.Blob  };
    return this.http.get(url, options).map(
    (res) => {
        return new Blob([res.blob()], { type: 'application/pdf' });
    });
  }

In component file

this.dataService.downloadPDF(url).subscribe(res => {
  const fileURL = URL.createObjectURL(res);
  window.open(fileURL, '_blank');
});
