How to use the svelte/store.writable function in svelte

window.location = `/index.html?thread=${encodeURIComponent(hash)}#/thread`
        break
      case "&":
        window.location = `http://localhost:8989/blobs/get/${hash}`

      case "@":
        window.location = `/index.html?feed=${encodeURIComponent(hash)}#/profile`
        break
      case "#":
        window.location = `/index.html?channel=${hash.replace("#","")}#/channel` 
        break
    }
  }
}
