Building a CRUD App with TanStack React-Query and React

When building a web application, it’s common to need to perform CRUD operations – Create, Read, Update, and Delete – on data. In recent years, there has been a rise in the popularity of modern frontend frameworks such as React, which provide powerful tools for building interactive user interfaces. One of the challenges in building CRUD applications is managing the state and handling asynchronous data fetching and updating. This is where libraries like React-Query come into play.

React-Query is a library for managing, caching, and updating asynchronous data in React. It provides a powerful set of hooks and utilities for managing data fetching, caching, and updating. Combined with React, it provides a robust foundation for building CRUD applications.

Setting Up the Project

To get started with building a CRUD app using TanStack React-Query and React, we first need to set up a new React project. We can do this using Create React App, a popular tool for setting up new React projects:

			npx create-react-app my-crud-app
			cd my-crud-app
			npm install react-query
		

Creating the CRUD Operations

With our project set up, we can now start building the CRUD operations for our app. Using React-Query, we can define queries and mutations for fetching and updating data. For example, we can create a query to fetch a list of items from an API:

			import { useQuery } from 'react-query';
			const { data, isLoading, isError } = useQuery('items', fetchItems);
		

Similarly, we can define mutations for creating, updating, and deleting items:

			import { useMutation } from 'react-query';
			const createItem = useMutation(createNewItem);
			const updateItem = useMutation(updateExistingItem);
			const deleteItem = useMutation(deleteExistingItem);
		

Building the User Interface

With the CRUD operations defined, we can now build the user interface for our app. We can use React components to display the data and provide forms for creating and updating items. We can also use the `useQuery` and `useMutation` hooks provided by React-Query to interact with the data and handle loading and error states.

Conclusion

Building a CRUD app with TanStack React-Query and React provides a powerful and efficient way to manage data fetching, caching, and updating in a React application. By combining the capabilities of React and React-Query, developers can build robust and scalable CRUD applications with ease.
