| Thanks to Metro bundler, there are two modes your React Native application can run in:</p><ol><li><p><strong>Debug mode</strong>. Running <code>npx react-native start</code> spawns the <em>Metro bundler</em> on port 8081 (by default). It serves JavaScript files of your app over HTTP, expecting that the native code will request it right upon the launch on the mobile device. Thus, the native app keeps re-downloading and executing the new code every time you change the code locally.</p></li><li><p><strong>Release mode</strong>. In contrast to the debug mode, <em>Metro bundler</em> does not need to run as a server on the side. It bundles your JavaScript code once into the native app binary file. Hence, every edit to the source code requires rebuilding the entire app binary and reinstalling it on the device before you can see the effect.</p></li></ol><p>There are two ways to configure the <em>Metro bundler</em> to use your mocks: quick (<strong>debug mode</strong> only) and universal. | |
