3‐ delByID Command

delByID Command

The delByID command is used to delete data from a database managed by the jsonverse package based on a specified ID. It is a method of the jsonverse class and allows you to remove specific data items from a data store.

Syntax

jsonverse.delByID(id);

• id (string): The unique identifier of the data item you want to delete.

Example Usage (With Promises)

const Jsonverse = require("jsonverse"); // Import the jsonverse package
// Initialize the JSONDatabase instance
const db = new Jsonverse({
  dataFolderPath: "./MyData", // data directory
  logFolderPath: "./MyLogs", // logs directory
  activateLogs: true, // to enable the logs set this value to true
});

// Define the ID of the data item to delete
const itemIdToDelete = "12345"; // Replace with the actual ID

// Delete the data item with the specified ID using promises
jsonverse
  .delByID(itemIdToDelete)
  .then(() => {
    console.log("Data item deleted successfully.");
  })
  .catch((error) => {
    console.error("Error deleting data:", error);
  });

In this example, we create an instance of the jsonverse class and use the delByID method to delete a specific data item from the data store based on its ID. We handle the result using promises for asynchronous operation.

Example Usage (Without Promises)

const Jsonverse = require("jsonverse"); // Import the jsonverse package
const jsonverse = new Jsonverse("./data"); // Initialize jsonverse with data folder path

// Define the ID of the data item to delete
const itemIdToDelete = "12345"; // Replace with the actual ID

// Delete the data item with the specified ID using a callback function
jsonverse.delByID(itemIdToDelete, (error) => {
  if (error) {
    console.error("Error deleting data:", error);
  } else {
    console.log("Data item deleted successfully.");
  }
});

In this example, we create an instance of the jsonverse class and use the delByID method to delete a specific data item from the data store based on its ID. We handle the result using a callback function for asynchronous operation.

This documentation provides an overview of the delByID command in the jsonverse package, demonstrating how to delete data items by their unique IDs with and without promises.
