How to use the setItem function from localforage

localforage.setItem is a function that sets a key-value pair in a local storage database, using the IndexedDB, WebSQL, or localStorage API.

How does localforage.setItem work?

localforage.setItem works by taking two inputs: a key and a value.

The function then stores the key-value pair in a local storage database using the IndexedDB, WebSQL, or localStorage API, depending on the capabilities of the user's browser.

If the browser supports IndexedDB or WebSQL, localforage will use these APIs to store larger amounts of data than what localStorage is capable of storing.

If the browser only supports localStorage, localforage will use that API instead.

By using localforage.setItem, you can store data locally on the user's device, allowing for faster access to frequently used data and improving the user experience of your application.

const localforage = require("localforage");

// Define a key and value
const key = "myKey";
const value = "myValue";

// Store the key-value pair in local storage
localforage
  .setItem(key, value)
  .then(() => console.log("Value stored successfully!"))
  .catch((err) => console.error("Error storing value:", err));

In this example, we first require the localforage library. We then define a key and value that we want to store in the local storage database. We call the localforage.setItem function, passing in the key and value as inputs. The function returns a Promise that resolves when the key-value pair has been successfully stored, or rejects with an error if there was a problem storing the data. We log a success message if the Promise resolves, or an error message if it rejects. The resulting output demonstrates how localforage.setItem can be used to store a key-value pair in a local storage database.
