Beyond the Basics: Coding with Wix for Advanced Features

Why Wix Coding Transforms Basic Websites into Business Powerhouses

Wix coding opens up a world of custom functionality that goes far beyond what you can achieve with drag-and-drop alone. While Wix's visual editor is perfect for getting started, adding code through Velo by Wix lets you build the kind of dynamic, interactive experiences that convert visitors into customers.

Quick Answer for Wix Coding:

• Enable Dev Mode - Toggle on coding features in Wix Studio or Wix Editor

• Use $w selector - Interact with page elements using JavaScript

• Add event handlers - Create interactive buttons, forms, and animations

• Connect databases - Build dynamic pages with CMS collections

• Integrate APIs - Add third-party services like payments and analytics

• Deploy serverless - No server management required

If you've been wondering why your e-commerce site isn't converting or why visitors aren't engaging with your content, the answer often lies in adding custom functionality that makes your site work for your business instead of just looking pretty.

With over 200 million websites powered by Wix, Velo by Wix has emerged as the platform that lets you build full-stack web applications up to 2x faster than traditional development. You get the visual builder you love plus the coding power you need.

The beauty of Wix coding is that it meets you where you are. Start with simple interactions like animated buttons or character counters. Then scale up to complex features like custom booking systems, dynamic product catalogs, or real-time inventory management.

I'm Athena Kavis, and over the past 8 years, I've designed over 1,000 websites using advanced wix coding techniques to help businesses transform their online presence. Through Quix Sites, I've seen how the right custom functionality can triple sales and boost engagement by 40% or more.

The Power Shift from Drag-and-Drop to Custom Code

When we first meet with clients in Las Vegas, many come to us with beautiful Wix sites that just aren't performing. They've mastered the visual builder—their sites look professional and polished. But something's missing. Visitors browse but don't buy. Forms get abandoned. The site feels static rather than engaging.

That's where wix coding becomes a game-changer. Instead of being limited to pre-built widgets and standard functionality, you can create exactly what your business needs. Need a custom calculator for your pricing? Build it. Want a multi-step booking form that captures specific client information? Code it. Looking to auto-generate product pages from your inventory database? Velo makes it possible.

The shift from drag-and-drop to custom code isn't about abandoning Wix's visual strengths—it's about amplifying them. You keep the WYSIWYG editor that makes design intuitive, but you add the programming power that makes sites truly functional.

Who This Guide Is For

This guide is perfect for three types of people:

Designers who want to offer clients more than just pretty websites. If you're tired of saying "sorry, Wix can't do that," this guide will show you how to say "yes, and here's how we'll build it."

Entrepreneurs who need their websites to work harder for their businesses. Maybe you're running an e-commerce store, a service business, or a content site—custom functionality can be the difference between a hobby site and a revenue generator.

Developers who are curious about low-code platforms but don't want to sacrifice power or flexibility. Velo offers a surprisingly robust development environment that might just change how you think about rapid prototyping and deployment.

Why Velo & Wix Coding Lift Your Site

Here's what happens when you add wix coding to your website: suddenly, everything becomes possible. At Quix Sites, we've watched clients transform their struggling websites into customer-converting machines simply by open uping the power of Velo by Wix.

Velo isn't just another coding tool—it's a complete full-stack development platform that turns your Wix site into a dynamic web application. Think of it as giving your website a brain upgrade. Instead of static pages that just sit there looking pretty, you get interactive experiences that respond to your users and drive real business results.

The secret sauce is Velo's serverless backend capabilities. You can build database-driven applications, connect to external APIs, and create custom user workflows without worrying about server management or hosting headaches. It's like having a development team built into your website builder.

We consistently see clients experience immediate improvements in user engagement after implementing custom functionality. One Las Vegas restaurant client saw their online reservations triple after we built a custom booking system that integrated with their existing POS system. Another e-commerce client boosted their conversion rate by 40% with a personalized product recommendation engine.

The numbers speak for themselves: over 80% of Wix users who enable Dev Mode report increased site interactivity and custom functionality. More importantly, they achieve this without the expense and risk of migrating to a completely different platform. You can explore more advanced Wix techniques that we use to transform businesses.

Velo in a Nutshell

Imagine giving your website JavaScript superpowers without the complexity. That's exactly what Velo delivers—a full-stack development environment that speaks plain JavaScript but works seamlessly with Wix's visual builder.

On the frontend, everything revolves around the magical $w selector function. Instead of wrestling with complicated DOM manipulation, you simply reference elements by their IDs. Want to make a button do something amazing? Just write $w('#myButton').onClick(() => { /* your magic happens here */ }). It's that straightforward.

The backend is where things get really exciting. You get serverless functions that handle data processing, API integrations, and complex business logic—all running in Wix's robust cloud infrastructure. No server maintenance, no scaling worries, no uptime anxiety.

What makes Velo brilliant is how it preserves Wix's visual design strengths while adding programming power. You still drag and drop to design your layout, but now every element can be improved with custom behavior. It's like having a professional development team integrated into your favorite design tool.

Studio vs Classic Editor vs Custom Embeds

Choosing the right development environment makes all the difference in your wix coding journey. At Quix Sites, we match the tool to the project based on complexity and team needs.

Wix Studio has become our preferred choice for new projects. The development experience feels like working in a professional IDE—think VS Code but built into your website builder. You get concurrent editing so multiple team members can collaborate simultaneously, AI-assisted code generation that speeds up development, and seamless GitHub integration for version control.

Wix Editor (Classic) still shines for existing sites or straightforward customizations. The code panel is clean and intuitive, while the Properties & Events panel makes element management simple. If you're adding interactive features to an established site, the classic editor often provides the fastest path forward.

Custom Code Embeds serve a specific purpose—integrating third-party scripts like analytics tracking or verification codes. However, they're limited to invisible functionality and can't interact with your page elements the way true Velo code can. Think of embeds as useful but limited compared to full wix coding capabilities.

When to Choose Blocks, Apps, or Service Plugins

Smart developers know when to build and when to buy. The Wix ecosystem offers multiple extension options, and choosing wisely saves time while ensuring your site remains maintainable and scalable.

Blocks become your best friend when you're creating reusable components. That custom booking widget or interactive calculator you built? Package it as a Block and use it across multiple client sites. You can even monetize your creativity by selling Blocks in the Wix marketplace—turning your wix coding skills into an additional revenue stream.

Apps from the Wix App Market handle common business needs efficiently. Before diving into custom development, check if a quality app already exists for email marketing, review management, or advanced e-commerce features. Sometimes the smartest code is the code you don't have to write.

Service Plugins open up exciting possibilities for headless architecture integration. You can replace or extend existing Wix functionality with external services—perhaps connecting to a specialized payment processor or integrating with a custom CRM system. This approach gives you enterprise-level flexibility while maintaining Wix's user-friendly interface.

Setup: Enabling Dev Mode & Picking Your Coding Environment

The moment you decide to add custom functionality to your Wix site, you'll need to enable Dev Mode. Think of it as open uping the developer toolkit that's been hidden inside your website builder all along. The process is straightforward, but the specific steps depend on whether you're working in Wix Studio or the classic Wix Editor.

At Quix Sites, we've guided hundreds of clients through this transition from visual design to wix coding. The most common question we get is "Will this break my existing site?" The answer is no—enabling Dev Mode simply adds new capabilities without affecting your current design or functionality.

Turning On Developer Mode in Wix Studio

Wix Studio makes enabling wix coding feel almost effortless. Simply click the Code icon in your left sidebar and select "Start Coding." Within seconds, you'll see the built-in Code panel appear alongside a new Code sidebar that gives you access to everything from page-specific code to backend files.

What really impressed us when we first started using Studio was the AI assistant that comes built into the Code panel. It's like having a coding mentor who can generate snippets, explain complex functions, and even catch errors before they cause problems. We've found this particularly valuable when working with clients who are new to JavaScript—the AI can bridge that knowledge gap in real time.

The concurrent editing feature in Studio has been a game-changer for our team workflow. While I'm working on the visual design, our developer can be writing custom functions simultaneously. Everything syncs automatically, which has cut our project delivery times significantly.

For more complex projects, you can click "Code in Wix IDE" to open a full browser-based development environment. This gives you VS Code-level features including debugging tools, an integrated terminal, and extensive extension support—all without leaving your browser.

Turning On Developer Mode in the Wix Editor

The classic Wix Editor takes a slightly different approach. Look for the "Dev Mode" toggle in your top menu—it's usually right next to the Preview button. Once you enable it, you'll see the Code Panel appear at the bottom of your screen, along with a Properties & Events panel that becomes essential for element management.

The Properties panel is where wix coding really starts to make sense in the classic editor. It shows you the unique ID for each element on your page and lets you attach event handlers through a visual interface. You can set up basic interactions here, then improve them with custom code.

We often recommend the classic editor for clients who prefer a more straightforward coding environment or when working on simpler customizations. The interface is less complex than Studio, which can be helpful when you're just starting your coding journey.

Coding Environments at a Glance

Choosing the right coding environment can make the difference between a smooth development experience and a frustrating one. The Code Panel works perfectly for quick customizations like adding click handlers to buttons or creating simple form validation. It's ideal when you need to make fast changes without switching contexts.

The Wix IDE becomes valuable for complex projects where you need advanced debugging capabilities or when multiple team members are collaborating. The real-time concurrent editing and built-in debugger make it feel like a professional development environment.

Local IDE integration with GitHub is the choice for advanced developers who need sophisticated version control or prefer working offline. While it has a steeper learning curve, it offers the full power of your favorite IDE combined with Wix's deployment system.

At Quix Sites, we typically start clients in the Code Panel for their first wix coding projects, then graduate them to the Wix IDE as their needs become more sophisticated. The beauty of Velo is that you can switch between environments as your project evolves.

Mastering Wix Coding on the Front-End

Frontend wix coding revolves around the $w selector function—think of it as jQuery designed specifically for Wix. This powerful tool lets you select, manipulate, and animate page elements with clean, readable JavaScript.

Wix Coding Essentials: $w Selector Power

The $w selector is your best friend when it comes to wix coding. It's like having a universal remote control for every element on your page. Instead of wrestling with complicated JavaScript selectors, you simply grab any element by its ID and start working with it.

Here's what makes the $w selector so neat. Every element in Wix gets a unique ID, and you can access it instantly. Want to change text when someone clicks a button? Easy. Need to hide a section until a form is filled out? Done in two lines of code.

$w.onReady(function () {
    // Select a button and add click behavior
    $w('#submitButton').onClick(() => {
        $w('#statusMessage').text = 'Form submitted successfully!';
        $w('#statusMessage').show();
    });

    // Change text color based on content
    if ($w('#priceDisplay').text.includes('$0')) {
        $w('#priceDisplay').style.color = '#ff0000';
    }
});

The Wix API Reference becomes your coding bible. We keep it bookmarked because it shows you every property and method available for each element type. Text boxes have different capabilities than images, and buttons have different events than input fields.

One tip that saves hours of debugging: rename your element IDs to something meaningful. Instead of keeping the default text123, change it to priceDisplay or confirmationMessage. Your future self will thank you when you're updating code six months later.

Adding Interactivity with Event Handlers

Event handlers are where your site transforms from pretty pictures to engaging experiences. At Quix Sites, we see the biggest impact when we add smart interactions that respond to what users actually do on the page.

Click events are the foundation of most interactive features. They're perfect for buttons, cards, and any element users might tap or click:

$w('#calculateButton').onClick(() => {
    const price = parseFloat($w('#priceInput').value);
    const tax = price * 0.08;
    const total = price + tax;

    $w('#totalDisplay').text = `Total: $${total.toFixed(2)}`;
});

Input events create that real-time feedback that users love. Instead of waiting until form submission to validate data, you can guide users as they type:

$w('#emailInput').onInput(() => {
    const email = $w('#emailInput').value;
    const isValid = email.includes('@') && email.includes('.');

    $w('#emailStatus').text = isValid ? '✓ Valid email' : '✗ Invalid email';
    $w('#emailStatus').style.color = isValid ? '#00aa00' : '#aa0000';
});

Mouse events add polish and help reveal information progressively. They're great for hover effects and showing additional details without cluttering the initial view:

$w('#infoCard').onMouseIn(() => {
    $w('#detailsPanel').expand();
});

$w('#infoCard').onMouseOut(() => {
    $w('#detailsPanel').collapse();
});

The key is thinking about user flow. What does someone need to see first? What information helps them make decisions? What feedback confirms they're on the right track?

Smart UI Tricks—Repeaters, Sliders & Animations

Repeaters are absolute game-changers for any site with dynamic content. Instead of manually creating fifty product cards or blog previews, you connect a repeater to your data and let wix coding handle the heavy lifting.

We use repeaters constantly for e-commerce sites and portfolios. Here's how we typically set up a product gallery that updates automatically:

import wixData from 'wix-data';

$w.onReady(function () {
    // Load products and populate repeater
    wixData.query('Products')
        .limit(12)
        .find()
        .then((results) => {
            $w('#productRepeater').data = results.items;
        });

    // Handle clicks on repeater items
    $w('#productRepeater').onItemReady(($item, itemData) => {
        $item('#productImage').src = itemData.image;
        $item('#productName').text = itemData.name;
        $item('#productPrice').text = `$${itemData.price}`;

        $item('#buyButton').onClick(() => {
            // Add to cart logic here
            console.log(`Adding ${itemData.name} to cart`);
        });
    });
});

Animations bring personality to your site without overwhelming users. Wix provides smooth built-in effects that you can trigger exactly when needed:

$w('#welcomeMessage').hide();

$w('#enterButton').onClick(() => {
    $w('#welcomeMessage').show('fade', { duration: 1000 });
});

For more sophisticated animations, the timeline API lets you orchestrate multiple elements like a conductor leading an orchestra:

import { timeline } from 'wix-animations';

const welcomeSequence = timeline()
    .add($w('#logo'), { scale: 1.2, duration: 500 })
    .add($w('#tagline'), { opacity: 1, duration: 300 }, '-=200')
    .add($w('#ctaButton'), { y: 0, duration: 400 }, '-=100');

$w('#startAnimation').onClick(() => {
    welcomeSequence.play();
});

The secret to great animations is restraint. Use them to guide attention, provide feedback, or add delight—but never let them slow down the user experience. A well-timed fade or slide can make your site feel premium, while overdoing it makes it feel amateur.

Back-End Power: Databases, APIs & External Integrations

The backend capabilities of wix coding transform your site from a static presentation into a dynamic application. With Velo's serverless architecture, you get enterprise-level functionality without managing servers or worrying about scaling.

At Quix Sites, we've seen how powerful this backend functionality can be for Las Vegas businesses. A restaurant client went from manually managing reservations to having a fully automated booking system that syncs with their kitchen schedule. An e-commerce store owner can now track inventory in real-time and automatically update product availability across multiple sales channels.

Wix's Content Manager acts like an internal database, letting you store and retrieve data without external services. For our clients, this often means customer information, booking details, inventory data, or user-generated content—all stored securely within the Wix ecosystem. The beauty is that non-technical team members can manage this data through Wix's intuitive interface while developers access it programmatically.

Connecting to Wix CMS & External Databases

The Wix CMS uses collections—think of them as database tables with a user-friendly interface. You can create collections for anything: products, blog posts, customer reviews, or booking appointments. What makes this powerful is how easily you can display this data dynamically throughout your site.

Here's how we typically set up a customer review system for our clients:

import wixData from 'wix-data';

// Save a new review
export function submitReview(name, rating, comment) {
    const reviewData = {
        customerName: name,
        rating: rating,
        comment: comment,
        dateSubmitted: new Date(),
        approved: false  // Require manual approval
    };

    return wixData.insert('Reviews', reviewData)
        .then((result) => {
            console.log('Review saved:', result);
            return result;
        })
        .catch((error) => {
            console.error('Error saving review:', error);
            throw error;
        });
}

// Load approved reviews for display
export function getApprovedReviews() {
    return wixData.query('Reviews')
        .eq('approved', true)
        .descending('dateSubmitted')
        .limit(10)
        .find();
}

Dynamic pages automatically generate individual pages for each item in a collection. If you have a products collection, Wix creates a unique URL and page for every product. This is incredibly powerful for e-commerce sites or content-heavy applications. One of our portfolio sites went from 20 manually-created product pages to over 500 automatically-generated ones, complete with SEO optimization for each item.

Data sets provide the bridge between your collections and page elements. You can bind repeaters, forms, and other elements directly to your data, creating real-time connections that update automatically when your content changes.

For external databases, Velo supports connections to services like MongoDB, MySQL, or third-party APIs. This lets you integrate existing business systems without data migration. We've helped clients connect their Wix sites to existing CRM systems, inventory management tools, and customer databases.

Building Serverless APIs with HTTP Functions & Routers

HTTP functions let you expose your site's functionality as custom APIs. This is perfect for mobile apps, third-party integrations, or webhook endpoints. The serverless nature means you only pay for what you use, and scaling happens automatically.

Here's a simple API endpoint we built for processing contact form submissions:

// In backend/http-functions.js
import { ok, badRequest, serverError } from 'wix-http-functions';
import wixData from 'wix-data';

export function post_contact(request) {
    const { name, email, message } = request.body;

    // Validate input
    if (!name || !email || !message) {
        return badRequest({ error: 'Missing required fields' });
    }

    // Save to database
    const contactData = {
        name: name,
        email: email,
        message: message,
        dateReceived: new Date(),
        status: 'new'
    };

    return wixData.insert('ContactSubmissions', contactData)
        .then((result) => {
            return ok({ 
                success: true, 
                submissionId: result._id 
            });
        })
        .catch((error) => {
            console.error('Contact form error:', error);
            return serverError({ error: 'Failed to save submission' });
        });
}

Custom routes handle specific URL patterns and can serve different content based on the request path. This is useful for creating API endpoints, handling webhooks from payment processors, or building single-page applications. We've used routers to create custom admin dashboards and client portals that feel like native web applications.

Webhooks let your site respond to external events in real-time. When a payment is processed, an email is opened, or an inventory item runs low, your site can take immediate action without manual intervention.

Securely Calling Third-Party Services

The Fetch API handles external service integration securely. Whether you're connecting to payment processors, email services, or data providers, wix-fetch provides a secure way to make HTTP requests from your backend code.

Here's how we implement a currency converter using an external exchange rate API:

import { fetch } from 'wix-fetch';
import { getSecret } from 'wix-secrets-backend';

export async function convertCurrency(amount, fromCurrency, toCurrency) {
    const apiKey = await getSecret('EXCHANGE_API_KEY');
    const url = `https://api.exchangerate.com/convert?from=${fromCurrency}&to=${toCurrency}&amount=${amount}&key=${apiKey}`;

    try {
        const response = await fetch(url);
        const data = await response.json();

        if (data.success) {
            return {
                originalAmount: amount,
                convertedAmount: data.result,
                exchangeRate: data.rate,
                fromCurrency: fromCurrency,
                toCurrency: toCurrency
            };
        } else {
            throw new Error(data.error);
        }
    } catch (error) {
        console.error('Currency conversion failed:', error);
        throw new Error('Unable to convert currency at this time');
    }
}

The Secrets Manager stores API keys and sensitive configuration securely. Never hard-code API keys in your frontend code—always use the secrets system for production applications. This is crucial for maintaining security, especially when integrating with payment systems or accessing sensitive customer data.

NPM packages extend your backend capabilities even further. You can import popular JavaScript libraries for data processing, image manipulation, or complex calculations. This means you're not limited to basic functionality—you have access to the entire JavaScript ecosystem while maintaining the simplicity of the Wix platform.

Best Practices, Testing, Security & Collaboration in Wix Coding

Building professional websites with wix coding goes way beyond making things work—you need code that's organized, secure, and actually maintainable six months from now. After designing over 1,000 websites at Quix Sites, I've learned that the difference between a quick fix and a lasting solution often comes down to following solid development practices from day one.

The good news? Velo gives you the tools to build like a pro, even if you're just getting started with coding. For more comprehensive guidance on advanced Wix development techniques, check out our detailed post on How to Use Velo by Wix.

Organizing Your Project for Scale

Here's what I wish someone had told me when I started with wix coding: organization matters more than clever code. A well-structured project saves hours of debugging and makes collaboration actually enjoyable.

Page Code handles everything specific to individual pages. Think form handlers, page-specific animations, or unique interactive elements. Each page gets its own code file automatically, which keeps things tidy and prevents one page's code from breaking another's.

Your masterPage.js file is like the foundation of your house—it runs on every single page of your site. We use this for navigation behaviors, user authentication checks, and analytics tracking. But here's the key: use it sparingly. If you stuff everything into masterPage.js, you'll end up with a bloated file that's impossible to debug.

Public Files are your best friend for shared functionality. When multiple pages need the same calculation logic or formatting functions, create a public file and import it where needed. This keeps your code DRY (Don't Repeat Yourself) and makes updates much easier.

Backend Files handle the server-side magic—database operations, external API calls, and business logic that needs to stay secure. This code runs in Wix's serverless environment, so it can't access browser APIs or page elements directly.

Here's how we typically structure projects at Quix Sites:

├── Pages/
│   ├── Home (Page Code)
│   ├── Products (Page Code)
│   └── Contact (Page Code)
├── Public/
│   ├── utils.js (Helper functions)
│   ├── validation.js (Form validation)
│   └── animations.js (Reusable animations)
├── Backend/
│   ├── data.js (Database operations)
│   ├── api.js (External service calls)
│   └── email.js (Email sending logic)
└── masterPage.js (Global site functionality)

Preview, Debug & Stage Rollouts

Testing is where the magic happens—or where you find your brilliant code idea needs some work. Wix Studio's Preview mode lets you test functionality without affecting your live site. We never publish without thorough testing on both desktop and mobile. Trust me, that "simple" button that works perfectly on desktop might behave strangely on a phone.

The browser's Developer Console becomes your debugging companion. Don't be shy about using console.log() during development—it's like having a conversation with your code:

$w('#calculateButton').onClick(() => {
    const input = $w('#numberInput').value;
    console.log('User input:', input);

    const result = performCalculation(input);
    console.log('Calculation result:', result);

    $w('#resultDisplay').text = result;
});

Velo's Release Manager is a game-changer for staged rollouts. You can deploy new features to just 10% of visitors first, then gradually expand to 50%, and finally 100% once you're confident everything works. This approach has saved us from several potential disasters when major updates didn't behave as expected in the real world.

The Logs and Monitoring tools track errors and performance in production. Set up alerts for critical functions so you know immediately if something breaks. There's nothing worse than finding your contact form stopped working three days ago.

Keeping Code & Data Secure

Security in wix coding isn't optional—it's essential, especially when you're handling customer data or payment information. The Secrets Manager is your first line of defense for sensitive data like API keys, database credentials, and third-party service tokens. Never, ever expose these in frontend code where visitors can see them.

Role-based access controls who can modify your site's code and data. For team projects, assign appropriate permissions carefully. Designers might need page editing access but definitely don't need backend code access. It's not about trust—it's about preventing accidental changes that could break functionality.

When handling user data, especially for clients in regulated industries, implement proper validation and sanitization:

import { sanitize } from 'wix-data';

export function saveUserProfile(userData) {
    // Validate required fields
    if (!userData.email || !userData.name) {
        throw new Error('Email and name are required');
    }

    // Sanitize input data
    const cleanData = {
        name: sanitize(userData.name),
        email: sanitize(userData.email.toLowerCase()),
        phone: sanitize(userData.phone),
        dateUpdated: new Date()
    };

    // Save to database
    return wixData.insert('UserProfiles', cleanData);
}

For GDPR compliance, categorize your custom code snippets and implement proper consent management. This is especially important for our Las Vegas clients who serve international audiences. The regulations might seem complex, but Velo provides tools to handle compliance requirements without making your code overly complicated.

Frequently Asked Questions about Wix Coding

When we work with clients at Quix Sites here in Las Vegas, these are the questions that come up most often about wix coding. Whether you're just starting with Velo or planning a complex custom project, understanding these limitations and capabilities helps you make smart decisions about your website's functionality.

What limits apply on free Wix sites using Velo?

Free Wix sites do support wix coding through Velo, but they come with specific quotas that work fine for testing and small projects. You get 1,000 data items across all your collections, which might sound like a lot until you realize that includes every product, blog post, customer record, and form submission.

The system also limits you to 10 data collections maximum and 1,000 reads plus 60 writes per minute. In practical terms, this means your site can handle moderate traffic, but if you're building something that needs to process lots of data quickly, you'll hit these walls pretty fast.

Your backend code runs on shared infrastructure with 1 vCPU and 400 MB RAM. For simple interactions like contact forms or basic calculations, this works perfectly. But complex data processing or heavy API integrations will feel sluggish.

Most of our clients start with free plans to test their concepts, then upgrade once they see the potential. The premium plans offer dedicated resources and much higher quotas—essential for serious business applications.

How do I store and access secrets securely?

Security matters, especially when you're integrating payment systems or customer data. Velo's Secrets Manager handles this properly by storing sensitive information like API keys and database passwords in encrypted storage that's separate from your code.

You'll find the Secrets Manager in the Velo Sidebar. Add your sensitive values there with descriptive names like "STRIPEAPIKEY" or "EMAILSERVICETOKEN." Then access them in your backend code using the getSecret() function:

import { getSecret } from 'wix-secrets-backend';

export async function callExternalAPI() {
    const apiKey = await getSecret('MY_API_KEY');
    // Use the API key in your external service call
}

The critical rule: never put secrets in frontend code or public files. Anyone can view your page source and see everything in your frontend JavaScript. Always keep sensitive data in backend functions where it stays private.

Can I switch from built-in editor to local IDE mid-project?

Absolutely, and it's surprisingly smooth. You can enable Git integration and Wix CLI at any point without losing your existing work. This downloads your current code, database structure, and site configuration to a local repository.

The beauty of this approach is flexibility. Maybe you start with simple wix coding in the browser editor, then realize you need advanced debugging tools or want to work offline. The transition preserves everything—your page code, backend functions, and even your database collections sync automatically.

You can actually switch back and forth between local development and the browser-based editor as your needs change. Some of our team members prefer the local IDE for complex logic but switch back to the browser for quick tweaks and testing.

This flexibility has saved us countless hours on client projects where requirements evolve or team members have different preferences for development environments.
