BlockSuite (pronounced "block sweet" 🍬) is the open-source editor project behind AFFiNE. It provides an out-of-the-box block-based editor built on top of a framework designed for general-purpose collaborative applications. This monorepo maintains both the editor and the underlying framework.

BlockSuite works very differently than traditional rich text frameworks. Feature highlights:

• 📝 Block-Based Editing: BlockSuite breaks down rich content into discrete contenteditable blocks, avoiding pitfalls using traditional monolithic rich text container.
• 🧬 Intrinsically Collaborative: By harnessing the power of CRDT, any application built with BlockSuite effortlessly supports real-time collaboration right from the start.
• 🧩 Framework Agnostic: With UI components implemented using Web Components, BlockSuite provides editors that can be easily embedded and eliminates the risk of vendor lock-in.
• 🎯 Incremental State Sync: The state updates in BlockSuite can be incrementally encoded as standardized binaries, enabling efficient data synchronization over various network protocols.
• 📏 Compact Rich Text: BlockSuite builds its own rich text component. With minimal responsibilities that benefits from the block-based architecture, this component is light, simple and reliable.
• 🎨 Hybrid Infinite Canvas: A high performance canvas-based renderer is also provided by BlockSuite, fulfilling needs for whiteboard functionalities.
