Documentation

Overview

Package webui embeds a pinned release of the mast-web operator UI (github.com/go-steer/mast-web) so the agent binary can serve it at /ui/* on its attach listener when the --ui flag is set.

The dist/ subdirectory is populated at build time by dev/tools/fetch-mast-web (which downloads the release tagged in the top-level .mast-web-version file). A .gitkeep file ensures the directory exists on a fresh clone so //go:embed succeeds even before fetch-mast-web has run; in that state HasAssets returns false and the --ui startup path emits a clear operator-facing error instead of serving an empty UI.

Functions

func FS 

func FS() (fs.FS, error)

FS returns the embedded SPA file system rooted at dist/. Always succeeds — the //go:embed directive is satisfied by the .gitkeep placeholder when fetch-mast-web hasn't been run. Use HasAssets to check whether the bundle is actually populated.

func HasAssets 

func HasAssets() bool

HasAssets reports whether the embedded bundle contains a real SPA (presence of dist/index.html), as opposed to just the .gitkeep placeholder. Used by the --ui startup path to fail fast with a useful error when the build didn't populate the assets.
