Hi Ashish,

Glad you’ve found the article useful and are using Azle on your projects.

You can download files in your browser using Azle’s download_file function:

az.download_file({
    "filename" : "my_file",
    "file_path" : "img/my_image.png"
})

If you want to allow a user to download a file by clicking on a button you can first add the button:

az.add_button("target_class", target_instance, {
    "this_class" : "my_button",
    "text" : "DOWNLOAD FILE"
})

…and then add a click event to the button that calls download_file:

az.add_event("my_button", 1, {
    "type": "click",
    "function": function() {
        az.download_file({
             "filename": "my_file",
             "file_path": "img/my_image.png"
        })
    }
})

Here is me doing this with one of my images:

You can also use Azle’s download_text_as_file function if you want to write some text output to a file that a user can download:

az.download_text_as_file({
    "filename" : "my_text",
    "text" : "This is some text inside a file."
})

Here’s a Fiddle.

Let me know if that helps, or if you have any other questions. Happy to help out.
