Most of the work is done for you. Just download the `TTF` or `OTF` files you want to use, place them in `./app/theme/fonts/` and load them in the `index.ts` file in that same directory. + +ignite integrated `expo-fonts` according to [this guide](https://docs.expo.io/versions/latest/sdk/font/). + +## For Non-Expo Projects + +1. Find a font in `TTF` or `OTF` format that you like and put it in `./assets/fonts/`. I picked [this one](https://fonts.google.com/specimen/Shadows+Into+Light). +2. Now run `npx react-native link`. Even though we're past react native 0.60 we can still use this command to link the fonts. This is a one-way operation. You'll have to remove fonts yourself later if you want to remove them from your app. This will add items to your xcode project and `Info.plist` file as well as putting some files in place for android to bundle (specifically, it will move the font files to `./android/app/src/main/assets/). +3. Both iOS and Android changes must be committed to source control, but sometimes other common libraries like `react-native-vector-icons` may mess with this process and add some fonts you don't intend to ship. Make sure to review these changes carefully before pushing any changes to source control. +4. The tricky part is next: knowing what font family to use. iOS uses the family name like `{fontFamily: 'ShadowsIntoLight'}` whereas on android, you must include all the different variations of the font you will use and reference them by their _filename_. So I downloaded `ShadowsIntoLight-Regular.ttf` that means android must use `{fontFamily: 'ShadowsIntoLight-Regular'}` (yes, it's case sensitive 🙄). [There are components to help you deal with this](https://github.com/lendup/react-native-cross-platform-text) or you can roll your own based on your needs and something like: + +``` +const CUSTOM_FONT_TEXT: TextStyle = { + fontFamily: Platform.select({ + ios: "ShadowsIntoLight", // The font family name + android: "ShadowsIntoLight-Regular", // The file name + }), + // ... whatever else +} +``` |
