Dune Miniapp Builder

App Layout

Each app lives at /config/miniapps/<slug>/ with an app.json manifest and entry file.

Manifest (app.json)

Fields: slug, name, description, collection, status (published|building|archived|error), entry (relative path, defaults to index.html), order, tags.

• slug must match ^[a-zA-Z0-9][a-zA-Z0-9-_]*$
• entry must be relative and inside app directory

Host-Bridge Protocol

Miniapp sends: window.parent.postMessage({ type: 'dune:miniapp-action', requestId, action, payload }, '*') Host replies: window.postMessage({ type: 'dune:miniapp-action-result', requestId, ok, response }, origin) Always handle ok:false with user-visible error state.
