I built an in-browser Roku TV remote with ~80 lines of TypeScript. Here's how Roku's ECP API actually works
An in-browser Roku TV remote was created using approximately 80 lines of TypeScript. The remote utilizes Roku's External Control Protocol (ECP), which operates without authentication or documentation. The implementation faced challenges such as IP discovery and mixed-content requests, but ultimately provides a streamlined user experience for controlling Roku devices.
- ▪Roku's ECP API is accessible on all devices without authentication or API keys.
- ▪The browser-based remote requires users to input their TV's IP address due to browser limitations on sending UDP packets.
- ▪Commands are sent as POST requests to specific endpoints, allowing for direct app launches without navigating the home screen.
