Adding custom fonts to a React Native CLI project

Downloading and integrating Google Fonts into our project

To integrate custom fonts into a React Native CLI project, we will use Google Fonts like Quicksand and Raleway. Download the desired fonts from Google Fonts and extract the font files.

Integrating the Google Fonts into the project

Create an assets/fonts folder in your project and paste the TTF files of the downloaded fonts into it. Create a file to specify the font assets path in your project.

Linking the fonts to be used in project files

Ensure the fonts are linked correctly so they can be used in your project styles.

Using custom fonts in React Native with Expo

Loading custom fonts using the Hook

In Expo, use the provided Hook for loading and using custom fonts in your project.

Using Google Fonts in Expo

Install the required Expo packages for using Google Fonts, such as Raleway and Quicksand, to easily incorporate them into your Expo project.

Using local custom fonts in Expo

For custom fonts not available in Google Fonts, you can load local custom fonts in your Expo project by referring to the specific font files.

React Native fonts best practices

Using system fonts for better performance

Utilize system fonts for improved performance, as they are readily available on devices and offer a native feel to users. Specify platform-specific font families for a consistent look across different platforms.

Dynamic font loading and preventing FOIT

Avoid FOIT by implementing dynamic font loading strategies to ensure fonts are loaded before rendering the UI. Verify font formats to ensure compatibility with the target platform.

Using unsupported font formats

Check platform support for font formats like .ttf or .otf to ensure compatibility and proper rendering of custom fonts in your React Native applications.
