Introduction

Inkstream is a developer SDK for embedding a rich text editor into React applications. It is built on ProseMirror and exposes a clean plugin API, a React component, and a licensing system for freemium monetisation.

Architecture overview


@inkstream/react-editor       ← React component + toolbar + hooks
  └── @inkstream/editor-core  ← Plugin system, schema, license manager
        └── prosemirror-*     ← ProseMirror document model & state

External packages (registered as plugins):

@inkstream/heading
@inkstream/font-family
@inkstream/link-bubble
@inkstream/image
@inkstream-dev/pro-plugins (private — requires license)

Design goals

Register only what you use — each feature is a plugin; unused plugins add zero code
Schema is dynamic — the ProseMirror schema is built from registered plugins at initialisation time
Secure by default — without a licenseValidationEndpoint, all plugins are treated as free tier
Undoable by default — all content mutations go through ProseMirror transactions; undo/redo works out of the box
