Fuchsia VS Code Extension

The Fuchsia VS Code Extension streamlines Fuchsia development by integrating essential tools and workflows within the editor.

Visit the fuchsia.dev reference for a detailed walkthrough of this extension's features, Using the Fuchsia extension for VS Code.

Setup

Ensure you have a Fuchsia source checkout. You may need to configure the path to your ffx tool:

1. Go to Settings > Extensions > Fuchsia
2. Set the Fuchsia: Ffx Path to the absolute path of your ffx executable.

If not set, the extension will search for ffx in ./tools/ffx and ./.jiri_root/bin/ffx.
