monaco

Configurable Monaco (VS Code) code editor. The third sandboxed heavy-JS plugin. Canonical doc is {code, language}; syntax highlighting runs worker-free on the main thread (opaque-origin safe), with an opt-in real-worker path. Supports a diff-editor mode and per-instance language/theme/read-only/minimap/word-wrap config.

import "github.com/DonaldMurillo/gofastr-plugins/monaco"

app.RegisterPlugin(monaco.New())

Isolation

Runs in an opaque-origin iframe

The frame never gets allow-same-origin, so it cannot reach host cookies, the database, or the host DOM. It talks to the host only over the versioned postMessage bridge, limited to the capabilities listed below.
