Most restaurants have a menu to help customers order food seamlessly. In this article, you'll build an app to store restaurant menus.
You'll be exploring the rich capabilities of Xata, a serverless database with built-in powerful search and analytics, and Cloudinary, a cloud-based image, and video management service.
Prerequisites
A basic understanding of JavaScript and Next.js is needed to follow along with this article.
Repository
You can find the complete code used in this article on GitHub.
Project Setup
Node has to be installed on your computer to set up the Next.js application. To install Node, go to the Nodejs website and follow the instructions to install the software compatible with your operating system.
You can verify the Node.js installation by running the command below:
node -v
v16.10.0 //node version installed
To create the Next.js app, run the command below. It will automatically set up a boilerplate Next.js app.
npx stands for Node Package Execute. It executes any package from the npm registry without installing it.
npx create-next-app@latest <app-name>
# or
yarn create next-app <app-name>
After the installation is complete, change the directory into the app you just created:
cd <app-name>
Run npm run dev or yarn dev to start the development server on http://localhost:3000.
Setting up Xata database
Create a new database on your Xata dashboard called restaurant_menu
Next, create a table and name it meals. Your table schema should look like this:
Setting up Xata instance
Run the command below to install the CLI globally:
npm install @xata.io/cli -g
Next, run xata auth login, which will prompt you to Create a new API key in the browser or use an existing one; go with the first option.
Now, in the project directory, run xata init. You will be prompted with several options to set up Xata in your app. Choose the options below:
Installing Cloudinary
Cloudinary provides a rich media management experience enabling users to upload, store, manage, manipulate, and deliver images and videos for websites and applications.
Install the package with the code below:
npm i @cloudinary/react
Fetching data from the database
To fetch the data from the database, first replace the existing code in the index.js file with the code below:
import FoodItem from '../components/FoodItem';
import styles from '../styles/Home.module.css';
import { getXataClient } from '../src/xata';
import { useState } from 'react';
export default function Home({ data }) {
return (
<div className={styles.container}>
<div>
<h1 className={styles.header}>Restaurant Menu</h1>
</div>
<div className={styles.foodListContainer}>
<FoodItem meals={data} />
</div>
</div>
);
}
export async function getServerSideProps() {
const xata = getXataClient();
const data = await xata.db.meals.getAll();
return { props: { data } };
}
In the root of your project create a components folder. In the components folder, create a FoodItem.js file and add the code below:
import styles from '../styles/Home.module.css';
export default function FoodItem({ meals }) {
return (
<div>
{meals.map((meal) => (
<div className={styles.foodList} key={meal.id}>
<img src={meal.image_url} alt='image' width='100%' height='250' />
<div className={styles.details}>
<p>{meal.name}</p>
<p>
<b>Price:</b> {meal.price}
</p>
</div>
</div>
))}
</div>
);
}
In the Home.module.css file, replace the contents with the code below:
.container {
background-color: white;
padding: 1.5rem;
height: 100vh;
}
.header {
color: black;
font-weight: 900;
text-align: center;
border: solid lightblue 10px;
padding: 20px;
}
.foodListContainer {
width: 50%;
height: auto;
float: left;
margin-right: 20px;
}
.foodList {
width: 45%;
height: auto;
padding: 1%;
display: inline-block;
background-color: beige;
margin: 2px;
}
.details {
margin-left: 60px;
color: black;
display: inline-block;
margin-left: 10px;
width: 70%;
}
.form {
width: 400px;
height: auto;
padding: 1%;
display: inline-block;
background-color: #626161;
}
.formInput {
width: 100%;
padding: 12px 20px;
margin: 8px 0;
display: inline-block;
border: 1px solid #ccc;
border-radius: 4px;
box-sizing: border-box;
}
.submitInput {
width: 100%;
background-color: #4caf50;
color: white;
padding: 14px 20px;
margin: 8px 0;
border: none;
border-radius: 4px;
cursor: pointer;
}
.submitInput:hover {
background-color: #45a049;
}
What has happened so far is that you:
- Imported the
getXataClientutility and initialized a new instance - Queried the
mealstable and fetched all records withgetServerSideProps - Passed the fetched data to the
FoodItemcomponent through props. - Did basic CSS setup ## Inserting new records in the database
To insert new data into the Xata database you created. First, you'd need to create a form and capture all the form data input by the user and send it via an API call to be stored in the database. Remember that you'd need to upload the Image selected by the user to Cloudinary.
In the index.js file, add the following code:
import FoodItem from '../components/FoodItem';
import styles from '../styles/Home.module.css';
import { getXataClient } from '../src/xata';
import { useState } from 'react';
export default function Home({ data }) {
return (
<div className={styles.container}>
...
<div className={styles.form}>
<label htmlFor='name'>
<b>Name:</b>
</label>
<input
type='text'
name='name'
className={styles.formInput}
onChange={(e) => setName(e.target.value)}
/>
<label htmlFor='price'>
<b>Price:</b>
</label>
<input
type='text'
name='price'
className={styles.formInput}
onChange={(e) => setPrice(e.target.value)}
/>
<label htmlFor='image'>
<b>Image:</b>
</label>
<input
type='file'
name='image'
className={styles.formInput}
onChange={(e) => setImageSrc(e.target.files[0])}
/>
<button
onClick={handleOnSubmit}
type='submit'
className={styles.submitInput}
>
Submit
</button>
</div>
</div>
);
}
export async function getServerSideProps() {
const xata = getXataClient();
const data = await xata.db.meals.getAll();
return { props: { data } };
}
This is just a basic HTML form. Now you’d need to capture the input data like so:
import FoodItem from '../components/FoodItem';
import styles from '../styles/Home.module.css';
import { getXataClient } from '../src/xata';
import { useState } from 'react';
import SearchResult from '../components/SearchResult';
export default function Home({ data }) {
const [imageSrc, setImageSrc] = useState([]);
const [name, setName] = useState();
const [price, setPrice] = useState();
return (
...
)
}
export async function getServerSideProps() {
const xata = getXataClient();
const data = await xata.db.meals.getAll();
return { props: { data } };
}
Now, create the function to upload the image to Cloudinary and store the data in the database.
Create a function called handleOnSubmit and add the following code to it:
import FoodItem from '../components/FoodItem';
import styles from '../styles/Home.module.css';
import { getXataClient } from '../src/xata';
import { useState } from 'react';
import SearchResult from '../components/SearchResult';
export default function Home({ data }) {
...
async function handleOnSubmit(event) {
event.preventDefault();
let response;
if (imageSrc) {
const body = new FormData();
body.append('upload_preset', 'bn1pyehj');
body.append('file', imageSrc);
response = await fetch(
'https://api.cloudinary.com/v1_1/chukwutosin/image/upload',
{
method: 'POST',
body,
}
).then((r) => r.json());
}
fetch('/api/add-food-item', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({
price,
name,
image_url: response.secure_url,
}),
}).then((r) => alert('record added successfully'));
}
return (
...
}
export async function getServerSideProps() {
const xata = getXataClient();
const data = await xata.db.meals.getAll();
return { props: { data } };
}
What you’re doing in this function is that you’re:
- Uploading the image, if it exists, to Cloudinary using your upload preset.
- Storing the data in the database through the next.js API.
You can find your upload preset in the Upload tab of our Cloudinary settings page by clicking on the gear icon in the top right corner of the dashboard page.
By scrolling down to the bottom of the page to the upload presets section, you’ll see your upload preset, or there will be an option to create one if you don't have any.
Storing data in the database
Create a new file in the api folder and name it add-food-item.js. Paste the code below in the file:
import { getXataClient } from '../../src/xata';
const xata = getXataClient();
const handler = async (req, res) => {
const { name, price, image_url } = req.body;
await xata.db.meals.create({
price: parseFloat(price),
name,
image_url,
});
res.end();
};
export default handler;
You get the data sent to the API and save it to the Xata database.
Adding Search functionality
To create a search functionality, create a new component file called SearchResult.js and pastre the code below:
import styles from '../styles/Home.module.css';
export default function SearchResult({ meals }) {
return (
<div>
{meals.map((meal) => (
<div className={styles.foodList} key={meal.record.id}>
<img
src={meal.record.image_url}
alt='image'
width='100%'
height='250'
/>
<div className={styles.details}>
<p>{meal.record.name}</p>
<p>
<b>Price:</b> {meal.record.price}
</p>
</div>
</div>
))}
</div>
);
}
This file is to show the search results.
Next, create a new file in the api folder called search.js and paste the code below into it:
import { getXataClient } from '../../src/xata';
const xata = getXataClient();
const handler = async (req, res) => {
const { searchTerm } = req.body;
const results = await xata.search.all(searchTerm);
res.send(results);
};
export default handler;
This is to query the database for the search term.
Displaying the search results
Hold the search term and search data in useState like so:
import FoodItem from '../components/FoodItem';
import styles from '../styles/Home.module.css';
import { getXataClient } from '../src/xata';
import { useState } from 'react';
import SearchResult from '../components/SearchResult';
export default function Home({ data }) {
...
const [searchTerm, setSearchTerm] = useState();
const [searchData, setSearchData] = useState();
....
Create a function to perform the search operation:
import FoodItem from '../components/FoodItem';
import styles from '../styles/Home.module.css';
import { getXataClient } from '../src/xata';
import { useState } from 'react';
import SearchResult from '../components/SearchResult';
export default function Home({ data }) {
...
async function handleSearch(event) {
event.preventDefault();
const result = await fetch('/api/search', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({
searchTerm,
}),
}).then((r) => r.json());
setSearchData(result);
}
...
Display the search results:
import FoodItem from '../components/FoodItem';
import styles from '../styles/Home.module.css';
import { getXataClient } from '../src/xata';
import { useState } from 'react';
import SearchResult from '../components/SearchResult';
export default function Home({ data }) {
..
return (
<div className={styles.container}>
....
{searchData ? <SearchResult meals={searchData} /> : ''}
{searchData ? '' : <FoodItem meals={data} />}
...
In displaying the search result, you first check to see that searchData has a value so that the SearchResult component and FoodItem don’t overlap.
Running the Application
To see the app in action, run npm run dev, and visit the URL. You should see a screen like this and be able to add and search for meals.
Conclusion
In this article, you created a restaurant menu app that helped you explore using Xata for seamless database storage and Cloudinary for easy image uploads.
