JavaScript CRUD Operation Using Google Sheet As A DataBase | Todo App Using Sheet As Database

In this article, we will explore how to create a simple todo app using JavaScript and Google Sheet as a database. We will perform CRUD operations (Create, Read, Update, Delete) on the todo list using JavaScript and Google Sheet API.

Setting up Google Sheet as a Database

To use Google Sheet as a database, you will need to create a new Google Sheet and enable the Google Sheets API in the Google Developer Console. Once the API is enabled, you will need to create credentials to access the API and obtain the API key and client ID.

Next, you will need to share the Google Sheet with the client email address obtained from the credentials. This will allow the JavaScript code to access and modify the Google Sheet.

Creating the Todo App

Let’s start by creating an HTML file with input fields for adding new todos and a table to display the list of todos.

JavaScript CRUD Operations

Now, let’s write JavaScript code to perform CRUD operations on the Google Sheet. We will use the Google Sheets API to add, retrieve, update, and delete data from the Google Sheet.

“`javascript
// JavaScript code for CRUD operations on Google Sheet

function addTodo() {
// Get the todo input value
var todo = document.getElementById(‘newTodo’).value;

// Add the todo to the Google Sheet
// Using Google Sheets API
}

function getTodos() {
// Get the list of todos from the Google Sheet
// Using Google Sheets API
// Update the table to display the todos
}

function updateTodo() {
// Update the todo in the Google Sheet
// Using Google Sheets API
}

function deleteTodo() {
// Delete the todo from the Google Sheet
// Using Google Sheets API
}
“`

Conclusion

In this article, we have learned how to create a simple todo app using JavaScript and Google Sheet as a database. By using the Google Sheets API, we can perform CRUD operations on the todo list, allowing users to add, retrieve, update, and delete their tasks. This is just a basic example of using Google Sheet as a database with JavaScript, and it can be extended to create more complex applications.
