Never use ScrollView to render huge lists<\/h3>\n\n\n\n<p>If you want to display items in React Native with scrollable lists, you have two options &#8211; ScrollView and FlatList components.<\/p>\n\n\n\n<p>ScrollView is easy to implement. However, it&#8217;s also one of the biggest reasons behind the <strong>React Native Android slow performance<\/strong>. The issue shows up even more when the number of items on the list is huge.&nbsp;<\/p>\n\n\n\n<p>Thus, you&#8217;d do better to use FlatList to handle large amounts of data in the list format. The component displays a scrolling list of changing but similarly structured data. The component works best with long lists of data where the number of items changes over time.&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" data-src=\"https:\/\/lh3.googleusercontent.com\/RzEG9Lt1WBYhVeoMIUYLQOHcjDgxQ9npHu0mN_zhKdl9djYQglluoWDQORz6bP2S2nt_YxwUHg6giwljpBDf7yZ7dsYFr9Nl50CkuWh5uZrqgjN142fKHeTF8O4lsNnIfw0T_3BxdXexCCtZ0yaKNjudi-KSSUrXC6pze1mwzOcT9Ku7OBWTihqmFAdIuJj6PzOsVldgGg\" alt=\"\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\" \/><\/figure>\n\n\n\n<p><a href=\"https:\/\/blog.codemagic.io\/improve-react-native-app-performance\/\">Source<\/a><\/p>\n\n\n\n<p>However, note that the items in the FlatList component are lazy-loaded. Thus, the feature can make the app use an excessive or inconsistent amount of memory.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Steer clear of unnecessary renders<\/h3>\n\n\n\n<p>Steering clear of unnecessary renders is a great way to reduce the overall rendering overhead.&nbsp;<\/p>\n\n\n\n<p>The reason behind this is when you avoid unnecessary renders, a component uses the previously cached properties and renders the JSX view returned by the functional component only once even when the component receives the same set of properties multiple times.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p>You can achieve the same by using React.memo. The feature handles memorization.<\/p>\n\n\n\n<p>Here&#8217;s an example for you to understand this better.<\/p>\n\n\n\n<p>In the example, the Animal component comes with a state variable called leg count. The variable is updated with a number that&#8217;s associated with each pair whenever the button is pressed.<\/p>\n\n\n\n<p>When the button is pressed, the WildAnimal component gets re-rendered. The function happens even though the text property of the component doesn&#8217;t change with render.<\/p>\n\n\n\n<p>React.memo can optimize the process by wrapping the contents of the WildAnimal component with itself.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" data-src=\"https:\/\/lh5.googleusercontent.com\/SKpwgBQ_3zo2ThjFXj7FNMP43iLmr3UlIofsjDvmjKSmcjLfZlocdDDV6jl2KsVURhJtXZtwhSjRXKcI2zPiInGVVYlnaFdsdEtUsnU47e_v8vnxjk_VvcrSRhCEQDoC1RkW1Eo1TPXimbb4VPSugLkm-2V67NbHkhe1eD1Gqjr7zv1mmvEso6HACXTGKQaF3lZ3RO10Hw\" alt=\"\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\" \/><\/figure>\n\n\n\n<p><a href=\"https:\/\/blog.codemagic.io\/improve-react-native-app-performance\/\">Source<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Steer clear of passing functions inline as props<\/h3>\n\n\n\n<p>Never pass a function inline when you need to pass a function as a property to a component. The reason behind this is doing so makes the parent re-render a new reference. The process creates an additional function.<\/p>\n\n\n\n<p>Thus, the child component re-renders without the props changing.&nbsp;<\/p>\n\n\n\n<p>Instead, declare the function as a class method or as a function inside a functional component. The process helps the references get rid of any possibility of across re-renders.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" data-src=\"https:\/\/lh5.googleusercontent.com\/M4hRBhJHez-lSTMW8HpJKddPthASiCAiKu5rGmAMgUZQJKY6IZM_QsfwfYDkYq_fU7gssir895YnLB-hCFb0A-dwhRqmVKX3er437MKqGXoKs9B31rFejC8aNDWskkoYq41zEZcnlDzUgcl08W16198rZxsenkOBdl4ASwf0o2iYdezgud7ur_6RHlXgzO6JaGLeaKDnWQ\" alt=\"\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\" \/><\/figure>\n\n\n\n<p><a href=\"https:\/\/blog.codemagic.io\/improve-react-native-app-performance\/\">Source<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Steer clear of arrow functions&nbsp;<\/h3>\n\n\n\n<p>If you&#8217;re asking &#8220;<strong>How to check the performance of a React Native app<\/strong>?&#8221; checking if you&#8217;re using arrow functions is a great way to measure the same.<\/p>\n\n\n\n<p>Arrow functions result in unnecessary re-renders.&nbsp;<\/p>\n\n\n\n<p>That&#8217;s why you shouldn&#8217;t use arrow functions as callbacks in your functions to render views. Furthermore, the arrow function allows each render to generate a new instance of that particular function.&nbsp;&nbsp;<\/p>\n\n\n\n<p>Therefore, whenever reconciliation happens, the <a href=\"https:\/\/flatlogic.com\/blog\/top-10-best-react-native-ui-components-for-mobile-app-development\/\">React Native framework<\/a> compares a difference. The framework never reuses old references if the function reference doesn&#8217;t match, thus avoiding unnecessary re-renders.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" data-src=\"https:\/\/lh4.googleusercontent.com\/jTxObuJn3HnO8W7l_fgYtafiKCDm2U1f5hhoCRemcSexb-oxdvrnKbB75WbFIQjJvmIbDgLEUoe_Yu94ZAFeYOK8hqIk6Vlh09FPXSbJD5OIIK5EX0VCPk11kt-2lKIssJ4jkyrGd91S-v63-_JoSqx7SqXINQk8u66uJ3jU8Q8oL8WP6SYgn3RyOSOeOYkLeiRjxwzIFw\" alt=\"\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\" \/><\/figure>\n\n\n\n<p><a href=\"https:\/\/blog.codemagic.io\/improve-react-native-app-performance\/\">Source<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Steer clear of implementing bulk reducers<\/h3>\n\n\n\n<p>A brilliant <strong>React Native performance KPI<\/strong> is not implementing bulk reducers.<\/p>\n\n\n\n<p>You should always update only the references that need to be updated. If an item comes with the same value as before, you don&#8217;t need to save a new reference for the same as it&#8217;ll create useless renders.<\/p>\n\n\n\n<p><section class=\"flatlogic-templates\"><a title=\"Bootstrap, Angular, React, Vue templates\" href=\"https:\/\/flatlogic.com\/templates\"><img decoding=\"async\" data-src=\"\/img\/flatlogic-templates.jpeg\" alt=\"React, Angular, Vue and Bootstrap templates\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\"><\/a> <p>In Flatlogic we create web &amp; mobile application templates built with <a title=\"React templates\" href=\"https:\/\/flatlogic.com\/templates\/react\">React<\/a>, <a title=\"Vue templates\" href=\"https:\/\/flatlogic.com\/templates\/vue\">Vue<\/a>, <a title=\"Angular templates\" href=\"https:\/\/flatlogic.com\/templates\/angular\">Angular<\/a> and <a title=\"React Native templates\" href=\"https:\/\/flatlogic.com\/templates\/react-native\">React Native<\/a> to help you develop web &amp; mobile apps faster.

Afterward, the React Native framework will load one module at a time.&nbsp;<\/p>\n\n\n\n<p>Furthermore, enabling the RAM format on the Android platform will create a set of files for each module on its own. You can force Android <a href=\"https:\/\/flatlogic.com\/generator\">to create a single file<\/a> similar to iOS as well. However, using several files needs less memory on Android and offers better performance.<\/p>\n\n\n\n<p>Edit the build phase &#8220;Bundle React Native code and images&#8221;.
