How to use the createInstance function from localforage

localforage.createInstance is a method provided by the LocalForage library that creates a new instance of LocalForage with its own configuration and database.

How does localforage.createInstance work?

localforage.createInstance is a method provided by the LocalForage library that allows you to create a new instance of LocalForage with its own configuration and database. When you call createInstance, it returns a new LocalForage instance that you can use just like the original one. However, this instance has its own set of options and settings, which allows you to use LocalForage with different databases or configurations in the same application. Here's an example of how you can use createInstance: javascript Copy code {{{{{{{ const localforage = require('localforage'); // Create a new instance of LocalForage with its own configuration const instance = localforage.createInstance({ name: 'my-db', storeName: 'my-store' }); // Set an item in the new instance's database instance.setItem('foo', 'bar') .then(() => { // Retrieve the item from the new instance's database return instance.getItem('foo'); }) .then((value) => { console.log(value); // 'bar' }); In this example, we first require the localforage library and then use createInstance to create a new LocalForage instance with a custom database name and store name. We then use the setItem method to set a value in the new instance's database, and retrieve it using the getItem method. Since the new instance has its own database, the value is not stored in the original LocalForage instance. By using createInstance, you can create multiple instances of LocalForage with their own settings and databases, which can be useful in situations where you want to store data in different databases or with different configurations.

const localforage = require("localforage");

// Create a new instance of LocalForage with its own configuration
const instance = localforage.createInstance({
  name: "my-db",
  storeName: "my-store",
});

// Set an item in the new instance's database
instance
  .setItem("foo", "bar")
  .then(() => {
    // Retrieve the item from the new instance's database
    return instance.getItem("foo");
  })
  .then((value) => {
    console.log(value); // 'bar'
  });

In this example, we use createInstance to create a new instance of LocalForage with a custom configuration. Specifically, we set the name property to 'my-db' and the storeName property to 'my-store'. We then use the setItem method to set a key-value pair in the new instance's database, and retrieve it using the getItem method. Since the new instance has its own database, the value is not stored in the original LocalForage instance. By using createInstance, you can create multiple instances of LocalForage with their own settings and databases, which can be useful in situations where you want to store data in different databases or with different configurations.
