Fun With Fiber Custom Renderers
summary
React Fiber exposes a first-class custom-renderer pathway that uses a host config with concrete hooks like createContainer and updateContainer, createInstance, createTextInstance, prepareUpdate and commitUpdate so a renderer actually builds, updates and tears down target instances. Examples include an emoji renderer that mutates text in finalizedInitialChildren, a React→Electron menu renderer, react-hardware for Arduino, and a full audio synth using a synth manager with MIDI that runs in Node/core audio and the browser and demonstrably plays sound; API surface is promise of a formal export but not fully exposed yet.
