Writing Wix Code (Velo): A Comprehensive Guide for Beginners and Advanced Users

Wix is a popular website building platform that allows users to create impressive websites easily and quickly. However, sometimes greater flexibility and the ability to customize the site to specific needs are required. This is where Wix Code (Velo) comes in, a powerful tool that allows you to add advanced functionality to websites.

What is Wix Code (Velo), why do we need it, and who is it for?

Wix Code (Velo) is a development tool that allows you to add JavaScript code to Wix websites. With Velo, you can create custom interactions, connect your site to external databases, build complex web applications, and more.

Why do we need Velo?

• Customization: Velo allows you to customize your site to unique needs, beyond the basic capabilities of Wix.

• Advanced functionality: You can add functions like custom forms, advanced online stores, content management systems, and more.

• Integration with external services: Velo allows you to connect your site to services like Google Maps, Salesforce, and more.

• Automation: You can automate actions on the site, such as sending automatic emails or updating data.

Who is Velo for?

• Velo is for web developers, designers, and anyone who wants to extend the capabilities of a Wix site.

• Even users with little programming experience can start using Velo with tutorials and code examples.

• Velo is suitable for anyone who wants a site with complex functionality, such as an online store, user portal, or web application.

Basic Programming Concepts

Before you start writing Velo code, it's important to know a few basic programming concepts:

• Variables: Variables are storage locations for data. For example, you can use a variable to store the username or product price.

• Functions: Functions are code segments that perform a specific action. For example, a function can calculate the VAT amount or send an email.

• Loops: Loops allow you to repeat a specific action multiple times. For example, you can use a loop to iterate through a list of products and display them on the site.

• Conditions: Conditions allow you to perform a specific action only if a specific condition is met. For example, you can display a message to the user only if they are logged in.

Libraries

Wix provides pre-built code libraries that contain functions and tools for using Velo. These libraries make development easier and allow you to add advanced functionality to your site quickly.

Functions

Functions are the building blocks of Velo code. They allow you to perform complex actions and divide the code into small, manageable parts.

Velo Code Examples

• Displaying a message to the user:

$w("#text1").text = "Hello, user!";

• Changing the color of an element:

$w("#button1").style.backgroundColor = "red";

• Displaying data from a database:

wixData.query("Products")
  .find()
  .then((results) => {
    if (results.items.length > 0) {
      $w("#repeater1").data = results.items;
    }
  });

Tips for Writing Velo Code

• Plan your code before you start writing.

• Use meaningful names for variables and functions.

• Divide the code into small, manageable parts.

• Use comments to explain the code.

• Test the code regularly to make sure it works as expected.

Summary

Wix Code (Velo) is a powerful tool that allows you to add advanced functionality to Wix websites. With Velo, you can create custom websites, connect your site to external databases, build complex web applications, and more.
