    zhuzhiliao

    zhuzhiliao

    Traditional toy that makes a wah-wah sound when it spins

    Zhuzhiliao is a browser simulation of the traditional Chinese bamboo cicada toy that makes a distinctive sound when swung in circles. The experience runs from a single dependency-free HTML file and can work offline without a build step or backend. Touch gestures, automatic swinging, and mobile motion sensors can drive the virtual toy. A fixed-step physics model simulates gravity, an elastic string, drag, tension, and rotational speed. Audio uses a real toy recording whose playback changes with motion, with a synthesized Web Audio fallback when the sample cannot be decoded. ...

    JavaScript library files for Offline, Sync, Sigv4.

    ...You can use any HTTP or GraphQL client to connect to a GraphQL API on AppSync. For front-end web and mobile development, we recommend using the Amplify clients which are optimized to connect to the AppSync backend. For DynamoDB data sources, use the DataStore category in the Amplify client. It provides the best developer experience and built-in conflict detection and resolution. For non-DynamoDB data sources in scenarios where you have no offline requirements, use the API (GraphQL) category in the Amplify client. For use cases where you are utilizing the Apollo V3 client, use the Apollo Links in this repository to help with authorization and subscriptions.
