In this tutorial, we will be building a serverless CRUD (create, read, update, delete) app using AWS Amplify and React. We will be using Amplify’s powerful set of tools and services to build a fully-fledged app that can create, read, update, and delete items from a database.
Before getting started, make sure you have the following tools installed:
- Node.js and npm
- React
- AWS Amplify CLI
We will be using the AWS Amplify CLI to create a new React project and set up the necessary AWS services.
To create a new React project, run the following command:
Next, navigate to the project directory and install the AWS Amplify dependencies:
Now, we can use the AWS Amplify CLI to set up the necessary AWS services. Run the following command to configure the CLI:
This will prompt you to sign in to your AWS account and create a new IAM user. Follow the prompts to complete the configuration.
With the CLI configured, we can now create a new Amplify project using the following command:
This will walk you through a series of prompts to configure the Amplify project. For this tutorial, we will be using the default options.
Next, we will create a new Amplify backend using the following command:
This will walk you through a series of prompts to create a new REST API. For this tutorial, we will be using the default options.
With the backend created, we can now add the necessary CRUD functionality to our app. First, let’s create a new React component to display a list of items from the database.
In your src directory, create a new file called List.js and add the following code:
This component uses the useEffect hook to fetch a list of items from the database when the component is mounted. It then displays a list of the items by mapping over the items array and rendering a div for each item.
Next, we will create a form to allow users to add new items to the database. In your src directory, create a new file called Create.js and add the following code:
This component includes a form with two input fields for the item’s name and description, and a submit button to create the new item. When the form is submitted, it calls the createItem mutation to add the new item to the database.
Now, we will create a component to allow users to update and delete existing items. In your src directory, create a new file called Update.js and add the following code:
This component includes a form with two input fields for the item’s name and description, and two buttons to update and delete the item. When the update button is clicked, it calls the updateItem mutation to update the item in the database. When the delete button is clicked, it calls the deleteItem mutation to delete the item from the database.
Finally, we will update the main App component to render these three components and provide them with the necessary data and functionality. In your src/App.js file, add the following code:
This component uses the useEffect hook to fetch a list of items from the database when the component is mounted. It then renders the List component with the list of items, the Create component to allow users to add new items, and the Update component for each item to allow users to update and delete the item.
That’s it! You now have a fully-fledged serverless CRUD app using AWS Amplify and React. You can easily extend this app to include more features and functionality by using Amplify’s other services and tools.
