How to use the dropInstance function from localforage

localforage.dropInstance is a method in the localForage library that deletes all the data associated with a given instance of localForage from the storage driver.

How does localforage.dropInstance work?

localforage.dropInstance is a method in the localForage library that deletes all the data associated with a given instance of localForage from the storage driver. When you call localforage.dropInstance(), you pass in the following parameters: options: An object that specifies the options for deleting the instance. This can include the name of the instance and the storeName of the storage driver you want to delete the data from. Once you pass in these parameters, the method performs the following steps to delete the instance: Get the storage driver: localforage.dropInstance() uses the getDriver() method to get the storage driver that corresponds to the instance you want to delete. Get the keys: Once the storage driver is obtained, localforage.dropInstance() uses the keys() method to get an array of all the keys that are associated with the instance. Delete the data: Finally, localforage.dropInstance() uses the removeItem() method to delete each key from the storage driver. Once all the keys are deleted, the instance is fully removed from the storage driver. Overall, localforage.dropInstance provides a simple way to delete all the data associated with a given instance of localForage from the storage driver. It's worth noting that this method is a destructive operation, and should be used with caution. Once the data is deleted, it cannot be recovered.

const localforage = require("localforage");

// Define the name of the instance you want to delete
const instanceName = "myInstance";

// Define the store name for the storage driver you want to delete the data from
const storeName = "localStorage";

// Define the options for deleting the instance
const options = {
  name: instanceName,
  storeName: storeName,
};

// Call the dropInstance() method to delete the instance
localforage
  .dropInstance(options)
  .then(() => {
    console.log(`Instance "${instanceName}" was successfully deleted.`);
  })
  .catch((error) => {
    console.error(
      `An error occurred while deleting instance "${instanceName}":`,
      error
    );
  });

In this example, we first import the localforage library using require. We then define the instanceName and storeName that correspond to the instance we want to delete and the storage driver we want to delete the data from, respectively. Next, we define an options object that contains the name and storeName properties, which we will pass to the dropInstance() method. Finally, we call the localforage.dropInstance() method and pass in the options object. If the operation is successful, the then() callback function will be executed and we will see a message indicating that the instance was deleted. If an error occurs, the catch() callback function will be executed and we will see an error message in the console. Overall, localforage.dropInstance provides a simple way to delete all the data associated with a given instance of localForage from the storage driver.
