GrapesJS is a client-side visual web page builder framework distributed as a pnpm monorepo. The core package exposes a `grapesjs.init()` entry point that creates an `Editor` backed by `EditorModel`, with pluggable modules for the component tree, iframe-based canvas, CSS rule composer, style manager with custom property types, block/asset/layer/trait managers, command registry, HTML/CSS parsers, code generators, storage adapters, internationalization, keyboard shortcuts, undo/redo, and a plugin system. The CLI package scaffolds, builds, and serves plugins. Although it contains a `DataSources` subsystem, this is an application feature for binding external records to component content, attributes, and styles, not a data-research pipeline; the repository is a software library, not research code.
