Add opentok-react as a dependency of your application: yarn add opentok-react Or if you’re still using npm: npm install –save opentok-react Then include opentok.js before your application: <script src=”https://static.opentok.com/v2/js/opentok.min.js”></script> Alternatively, wrap your top-level component using OpenTok with the preloadScript HOC. The HOC will take care of loading opentok.js for you before rendering. https://github.com/opentok/opentok-reacthttps://github.com/opentok/opentok-react-native-samples
