I am implementing a double slider for price range.There is a need to show the value when sliding by the user to select specific range.For that,I have used innerHTML which worked fine. But there is an error saying

Currently I'm trying to store a subset of my redux-state to localstorage. I was using the documentation from PWA Starter Kit to implement a basic storage, which works fine for now, but this only saves the complete state to the localstorage.

This isn't exactly what I want, because as mentioned, I only want to store a subset, like some specific action results (e.g. state.settings instead of state).

Every documentation and examples only store the complete state, I haven't found any comment that fits my need.

My current implementation

redux-store.js

I am currently encountering a problem which is probably simple, but I don't manage to nail it.

I have a polymer application using the latest version of lit-element (2.0.1).

Unfortunately after running the npm run build:static (behind it is polymer build) and serve it using: npm run serve:static (behind it is executing: polymer serve --port 5000 build/es5-bundled).

The lit-element.js is not available.

If I list the files in the project node_module I have:

In a lit-element component, I'm learning how to write to a Firebase document.

I set up the database reference as a constructor constant (docRef)... because it looked like a good place. However, I am not able to call it from the method writeToDb(). In the code below, everything works but you can see I have repeated the refDoc (=refDoc2).

I have tried "this.refDoc" but I get an error: Cannot read property 'set' of undefined. How do you do something similar in this case?

Thanks for any help!
