Build Custom, Interactive Components in Bravo with Webview Communication

Bravo Expert Juan Carlos is back — this time showing how to take your Bravo apps to a whole new level with Webview Communication.

Whether you’re creating custom maps, galleries, or dynamic HTML components, this feature unlocks the ability for your own web code to talk directly to Bravo — opening screens, sending data, or triggering actions.

What Is Webview Communication?

Bravo’s Webview Communication lets you embed your own HTML, CSS, and JavaScript inside your app — and connect it with Bravo’s navigation and data system.

This means you can:

Build rich, interactive UI elements beyond Figma
Pass data between your web component and your Bravo app
Trigger app actions such as open page, refresh data, or show alert
Extend your app with your own custom logic

It’s the perfect way to blend custom code power with Bravo’s visual no-code builder.

In the New Tutorial

In his latest video, Juan Carlos walks us through how he built a custom interactive map inside his app Syatrail — powered by Webview Communication.

“When a user taps a marker, the map sends a message to Bravo to open the detail page for that location,” JC explains.“It feels completely native — but it’s really just a simple bridge between the webview and Bravo.”

Here’s how it works:

Create a Webview Frame in Figma — simply name your frame webview and connect an external HTML file.
Load Your HTML — in JC’s case, it’s a custom map built with HTML, CSS, and JavaScript.
Send Messages to Bravo — using a small piece of code, the webview sends messages like:

‍window.Bravo.navigateTo({ href: "detailPage", hrefRemote: { id: "placeID123" }});

This tells Bravo which screen to open and what data to pass along.
Instant Interaction — when a user taps a location, the app opens the corresponding Bravo page, seamlessly.

What You Can Build With It

Webview Communication opens up endless possibilities:

🗺️ Interactive MapsDisplay custom maps or geolocation features powered by external APIs.
🖼️ Dynamic GalleriesCreate scrollable galleries or carousels with custom transitions.
🧠 AI-Powered WidgetsEmbed visual elements that show live AI-generated content.
📊 Custom DashboardsDisplay analytics, charts, or data visualizations with JS libraries.

The result: apps that feel native but are powered by your creativity and code.
