Blob stands for Binary Large Object and is a data type that can store binary data. This method is not restricted to the plain text entered by the user like the previous method. We can request any sort of data from an API and then use this approach to save data inside our computer. All the major browsers support all the above methods except the method using the Axios library. Internet Explorer still does not supports the native ES6 promises, and Axios depends heavily on them.

Notice in the GIF above that we have the same behavior as for the second method, only now we can monitor progress. After the file is completely downloaded, it will be sent to the browser and then it will be instantly saved to disk. Each of the above methods represents an update over the previous method. The first method is the easiest. In this, we simply forward the download process to the browser to manage it natively. This method is the preferred way when the application does not have to perform certain actions based on the load state. In the second, we manage the download internally and send it to the browser only when the download is complete. In this way, we can control the download inside the application and we can react depending on its status. This method works well for small files that are downloaded quickly, but when the file is too large, the user may think that the application is faulty, if nothing happens on the UI to indicate to the user that a download is in progress.
In the last method, we implement our own measurement of progress, which is similar to that in the browser. About Help Terms Privacy. Full-Stack Web Developer.
