Create a folder in your project folder, and add your fonts to it. Example:
Example: Here we added a folder in root called “mystuff”, then “fonts”, and inside it we placed our fonts:

Add the below code in package.json.
json { …
"rnpm": {
"assets": [
"path/to/fontfolder"
]
},
...
}
“rnpm”: {
“assets”: \\[
“mystuff/fonts”
\\]
\\}
react-native link command.<Text style={{ fontFamily: 'FONT-NAME' }}>My Text</Text>
Where `FONT-NAME` is the prefix platform specific.
### Android
FONT-NAME is the words before the extension in file. Example: Your font's file name is `Roboto-Regular.ttf`, so you would set `fontFamily: Roboto-Regular`.
### iOS
FONT-NAME is "Full Name" found after right clicking, on the font file, then clicking on "Get Info". ( Source: <https://stackoverflow.com/a/16788493/2529614> ), in the screenshot below, the file name is `MM Proxima Nova Ultra bold.otf`, however "Full Name" is "Proxima Nova Semibold", thus you would set `fontFamily: Proxima Nova Semibold`.

* Run `react-native run-ios` or `react-native run-android` again (this will recompile with the resources)
