Downcast

Downcast is a podcast app for iOS, Mac, Apple Watch, and CarPlay. Protocol Launcher allows you to generate official URL scheme links to import podcast feed subscriptions in Downcast.

Usage

There are two ways to use this library:

• On-Demand import from subpaths enables tree-shaking and keeps bundles small.
• Full Import from the root package is convenient but includes all app modules.

Pick On-Demand for production builds; Full Import is fine for quick scripts or demos.

Convenient. Good for quick scripts.

Notes

Downcast's official knowledge base documents itpc://, podcast://, feed://, and downcast:// as supported podcast feed URL schemes. When one of those URLs is opened, Downcast attempts to import a subscription for the podcast at that URL.

The subscribe() helper expects a complete URL that already uses one of those documented schemes. The subscribeFeedUrl() helper returns the exact documented Chrome RSS Subscription Extension template: downcast://feed-url=%s.

Downcast Scheme

On-Demand

import { open } from 'protocol-launcher/downcast'

const url = open()

Open downcast://
