Wix has long been lauded for its intuitive drag-and-drop interface, making website creation accessible to everyone. But for businesses and developers seeking deeper customization, dynamic data interactions, and seamless third-party integrations, Velo by Wix (formerly Corvid) is the game-changer. Velo empowers you to add custom JavaScript, interact with databases, and integrate APIs directly within your Wix environment, transforming a simple website into a powerful web application.
However, harnessing Velo's full potential often requires delving into code, and finding practical, problem-solving examples can be a significant hurdle. As digital engineering experts at 'Do Digitals', we understand this challenge. This post provides highly technical, real-world Wix Velo examples to help you overcome common development obstacles and elevate your Wix site to new heights.
Problem: You need to display a large collection of items (e.g., properties, job listings, products) with advanced filtering and pagination, which Wix's default repeaters can't handle efficiently or robustly.
Velo Solution: Use Velo to query your Wix database collections, dynamically render content, and implement sophisticated filtering logic client-side or server-side.
import wixData from 'wix-data';
$w.onReady(function () {
// Populate initial repeater
loadItems();
// Event listener for filter changes
$w('#filterDropdown').onChange(() => loadItems());
});
function loadItems() {
let query = wixData.query('YourCollection');
const selectedFilter = $w('#filterDropdown').value;
if (selectedFilter !== 'All') {
query = query.eq('category', selectedFilter);
}
query.find()
.then(results => {
$w('#repeater1').data = results.items;
// Connect repeater elements to data fields
$w('#repeater1').onItemReady(($item, itemData, index) => {
$item('#textTitle').text = itemData.title;
$item('#imageItem').src = itemData.mainImage;
});
})
.catch(error => console.log(error));
};
Problem: Your forms require complex validation rules (e.g., conditional fields based on previous input, custom regex patterns, real-time feedback) beyond Wix's basic built-in options.
Velo Solution: Implement custom validation functions and event handlers to ensure data integrity and a superior user experience.
$w.onReady(function () {
$w('#inputEmail').onCustomValidation((value, reject) => {
const emailRegex = /^\S+@\S+\.\S+$/;
if (!emailRegex.test(value)) {
reject('Please enter a valid email address.');
}
});
$w('#dropdownService').onChange((event) => {
if (event.target.value === 'Custom') {
$w('#textBoxCustomDetails').show();
$w('#textBoxCustomDetails').required = true;
} else {
$w('#textBoxCustomDetails').hide();
$w('#textBoxCustomDetails').required = false;
}
});
$w('#buttonSubmit').onClick(() => {
if ($w('#form1').valid) {
// Submit data or call backend function
console.log('Form is valid and ready to submit!');
} else {
console.log('Please correct the form errors.');
}
});
});
Problem: You need to connect your Wix site with external services (e.g., CRM, payment gateways, weather APIs) but require secure handling of API keys and server-side logic.
Velo Solution: Utilize Velo's backend web modules (`.jsw` files) to make HTTP calls to external APIs, keeping sensitive information secure and off the client-side.
http-functions.jsw or a custom web module like apiIntegrator.jsw):import { fetch } from 'wix-fetch';
export async function callExternalApi(endpoint, data) {
const apiKey = 'YOUR_SECURE_API_KEY'; // Stored securely, e.g., in Secrets Manager
const response = await fetch(`https://api.example.com/${endpoint}`, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': `Bearer ${apiKey}`
},
body: JSON.stringify(data)
});
if (response.ok) {
return response.json();
} else {
throw new Error(`API call failed: ${response.status} ${response.statusText}`);
}
}
import { callExternalApi } from 'backend/apiIntegrator';
$w.onReady(function () {
$w('#buttonSend').onClick(async () => {
const dataToSend = { name: $w('#inputName').value, email: $w('#inputEmail').value };
try {
const result = await callExternalApi('submit-lead', dataToSend);
console.log('API Response:', result);
$w('#textMessage').text = 'Data sent successfully!';
} catch (error) {
console.error('Error sending data:', error);
$w('#textMessage').text = 'Failed to send data.';
}
});
});
Problem: You need to create personalized user experiences where content or functionalities are visible only to specific user roles or individual members, beyond Wix's basic member area permissions.
Velo Solution: Implement custom logic to determine user roles and dynamically control element visibility or redirect users based on their authenticated status and custom roles.
import wixUsers from 'wix-users';
import wixLocation from 'wix-location';
$w.onReady(async function () {
if (wixUsers.currentUser.loggedIn) {
let user = await wixUsers.currentUser.getRoles();
if (user.roles.some(role => role.name === 'Admin')) {
$w('#adminPanel').show();
} else if (user.roles.some(role => role.name === 'Premium Member')) {
$w('#premiumContent').show();
} else {
$w('#basicContent').show();
}
} else {
// Redirect unauthenticated users or show login prompt
wixLocation.to('/login');
}
});
