Installing and Configuring HaRP for Nextcloud AppAPI is the next-generation deployment daemon for Nextcloud Hub 32+, replacing the older DockerSocketProxy (DSP). It acts as a dedicated bridge and proxy for External Apps (ExApps) , enabling them to communicate directly with clients via WebSockets and bypass the standard PHP stack for improved performance. 1. Prerequisites Before beginning the installation, ensure you have:
server core\/ajax\/update Use code with caution.

: For standard setups where ports are exposed to the host.
suggests that manual Docker Socket Proxying will eventually be deprecated in favor of this tunnel-based approach. This shift ensures that the Nextcloud ecosystem remains scalable and "cloud-native," allowing developers to build apps in any language that can be containerized, rather than being restricted to PHP. docker-compose.yml example for a HaRP setup, or should we troubleshoot a specific error message you've encountered? Adapting ExApps to HaRP - Nextcloud Documentation
Add the following lines:
: The HaRP container and the ExApp containers must share a network or have correctly mapped bridge ports to communicate. 📈 Future Outlook
: Enables real-time features like chat or live notifications, which were difficult to implement under older systems. FRP Tunneling
Add a custom PHP configuration file: .harp/overrides/php.ini Set Data Folder : Change this to /var/nextcloud_data
HaRP represents a significant step forward for the Nextcloud ecosystem. By providing a fast, secure, and WebSocket-ready proxy for external apps, it opens the door to a new generation of powerful, real-time features directly within your Nextcloud environment.
