StyleSheet

A StyleSheet is an abstraction similar to CSS StyleSheets

Create a new StyleSheet:

var styles = StyleSheet.create({
  container: {
    borderRadius: 4,
    borderWidth: 0.5,
    borderColor: '#d6d7da',
  },
  title: {
    fontSize: 19,
    fontWeight: 'bold',
  },
  activeTitle: {
    color: 'red',
  },
});

Use a StyleSheet:

<View style={styles.container}>
  <Text style={[styles.title, this.props.isActive && styles.activeTitle]} />
</View>

Code quality:

• By moving styles away from the render function, you're making the code easier to understand.
• Naming the styles is a good way to add meaning to the low level components in the render function.

Performance:

• Making a stylesheet from a style object makes it possible to refer to it by ID instead of creating a new style object every time.
• It also allows to send the style only once through the bridge. All subsequent uses are going to refer an id (not implemented yet).
