Use BlobURL instead of DataURL

Introduction

In this blog, I have explained How to Use BlobURl to preview file or download file.

Problem Statement

In the browser, on web page, when we need to preview or download file then, we deal with file as dataURl which consist the content-type followed by Base64 string as file content. But, Data URL that contains base64 string, can be very large and handling it (like sending one page to another in URL) can be time consuming. Additionally, we cannot have large string in URL.

Solution

Instead of large size Base64 string to preview or download the file we can use BlobURL. Blob object contains the file content and we can use it as URL which is a BlobURL to upload/download data and also, we can used as ‘src’ to > <>> <>> <> <><>> > <><>> >> – > <>> <>> <><>>< /> <>>< /> <>>< /> <>>< /> <>>< /> <>>< /> <>}< /> <>>< /> <>>< /> <>}< /> <>>< /> <>> <>> <>> <><>>< /> <>>< /> <>>< /> <>>< /> <>>< /> <>}< /> <>> <>><>> > <><>> <>>/<>. > <>“></> </>
