How to set data in HTML local storage using Python?

Question

I want to set data in HTML local storage using Python (I am using Flask framework). Do I need to use JavaScript?

Answer 1

You need to use JavaScript.

Python (server-side) knows nothing about JavaScript (client-side) where localStorage resides.

The easiest, however many times not the most efficient, way to approach the problem is

• You have a JavaScript JS snippet running in your HTML page

• This JS makes an AJAX request to the server-side Flask view. Try jQuery.getJSON()

• Flask view returns JSON data

• JS code receives the JSON and stores it in the localStorage

Alternative, if the amount of data is few bytes, you can pass it from the server-side to the client-side (JavaScript) using cookies.
