The ffx tool

Future Fuchsia experience (FFX) provides a service oriented interface to many common development and integration workflow operations that users may wish to perform against one or more Fuchsia target devices.

It is both a service runtime, and a collection of utilities, and it is intended for both users and infrastructure integrators alike.

Getting started

• Using ffx command line tool
• Developing for ffx

CLI

The Command Line Interface (CLI) provides the UX for FFX. It is responsible for:

• Parsing user parameters (CLI Parameters)
• Communicating with the daemon (starting it if necessary)
• Routing parsed parameters and requested FIDL proxies to the proper code path for execution

Daemon

The daemon runs in the background on the host device and manages:

• Target discovery
• Target lifecycle management (flashing, provisioning, and package serving)
• Facilitating communication with target devices

Remote control service

The remote control service runs on target devices and is responsible for providing access to the FIDL services running on the target.
