Javascript code download files

This time, we are using a JavaScript library called FileSaver. The example below presents the syntax to implement the saveAs FileSaver interface:. It sets the file to a Blob value. For instance, it is useful for preventing sensitive information from being sent to external servers. It includes but is not limited to multimedia objects , programs , and code snippets.

Remember: as Blob has size limitations based on the supported browser, FileSaver. See the table below to check the compatibility of FileSaver. Learn easily by using our HTML5 canvas examples.

In this approach, we will use the Axios library to download files. 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. The idea is to programmatically create an anchor link, and then trigger the click event. This method is especially helpful for dynamically generated file URLs.

Sometimes, you may want to save programmatically generated data as a file using JavaScript. That's where blobs and object URLs are useful. A Blob object is a file-like object used to represent raw immutable data. Blob objects contain information about the type and size of data they store, making them very useful for storing dynamic contents in the browser.
