// The widget is available as the global BluvoWidget object

orgId?: string; // Legacy option

tag?: Record<string, string>;

}The widget includes all necessary styling. The base font is inherited from your application, but you can override styles if needed:
.bluvo-widget, .bluvo-widget * {
font-family: your-custom-font, sans-serif;
}You can also directly import the Widget component for more advanced use cases:
import { Widget } from '@bluvo/widget-vanjs';
import van from 'vanjs-core';
// Create a widget manually
const widgetElement = Widget({
mode: 'connect',
// ... other options
});
// Mount it yourself
van.add(document.getElementById('container'), widgetElement);The widget is built using VanJS, a minimalist reactive UI framework. The main components include:
- Widget - Main container component
- WidgetHeader - Header with title and navigation controls
- WidgetFooter - Footer with branding and terms
- ExchangeList - List of available exchanges
- CredentialForm - Form for API key authentication
- ConnectionProgress - Connection status progress
- ConnectionSuccess - Successful connection view
- ConnectionError - Error handling view
- Transact - Transaction flow components

pnpm previewThis package uses GitHub Actions for continuous integration and deployment. The workflow is organized into two separate jobs:
- Builds and publishes the
@bluvo/connectpackage (dependency) - Only publishes if the package doesn't already exist on npm
- Runs first to ensure the dependency is available
- Depends on the publish-connect job completing successfully
- Updates the widget's package.json to use the npm version of
@bluvo/connect - Installs dependencies, builds, and publishes the widget
- Automatically bumps the version (patch)
- Only publishes if changes are detected in the package
The workflow triggers on:
- Pushes to the main branch that include changes to either package
- Manual workflow dispatch
Since this package is part of a monorepo and depends on the internal @bluvo/connect package, the CI/CD workflow:
- Checks if
@bluvo/connectis already published to npm - If not, it builds and publishes it first in a separate job
- Then updates the widget's package.json to use the npm version instead of the workspace reference (
workspace:*) - This ensures proper dependency resolution when building outside the monorepo context
The workflow file is located at .github/workflows/publish-widget-vanjs.yml.
- An NPM_TOKEN secret must be set in the GitHub repository settings
- The package must have a valid package.json with a name, version, and required fields
