@wisiendot/expo-unlimited-secure-store/src/uuid.js

An 'unlimited' secure store engine for expo projects, also compatible with redux-persist. (Expo's SecureStore was limited to 2KB in SDK v33)

const uuid = () => {
    let d = new Date().getTime();
    if (typeof performance !== 'undefined' && typeof performance.now === 'function') {
        d += performance.now();
    }
    return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, (c) => {
        const r = (d + Math.random() * 16) % 16 | 0;
        d = Math.floor(d / 16);
        return (c === 'x' ? r : (r & 0x3 | 0x8)).toString(16);
    });
};

export default uuid;
