storing information between elements

Imagine I have a requirement to include a data provider element for my users, like this:

<user-data-provider user-data="{{data}}"></user-data-provider>

This element would send an ajax request to retrieve the logged in user's information.

If I want to access this user data on multiple pages, I could simply add this tag wherever needed. However, the issue is that every time the browser encounters this tag, it triggers another ajax request, causing me to wait for the data to be fetched each time!

I am aware that I could create a variable on my main page and pass it to child pages, but that seems excessive to me!

Is there a way to persist user data across different pages within my application?

Thank you for your assistance.

Answer №1

There are multiple approaches to achieve this task.

  1. Implement the monostate pattern
  2. Have a single instance of the user-data-provider element in your root element or index.html and utilize iron-signals to propagate the data to other elements
  3. Utilize iron-meta for global state management
  4. Integrate an external state management framework like redux, with a polymer wrapper available at polymer-redux

It is advisable to opt for an external state management framework such as redux.

Polymer 1.0 Global Variables

Answer №2

When it comes to storing data, I rely on PouchDB, paired with Polymer's convenient prebuilt elements for seamless integration.

With this setup, accessing data has never been easier—all I have to do is utilize that specific component.
