Installation

Terminal
npx expo install expo-contacts

If you are installing this in an existing React Native app, start by installing expo in your project. Then, follow the additional instructions as mentioned by the library's README under "Installation in bare React Native projects" section.

Configuration in app.json/app.config.js

You can configure expo-contacts using its built-in config plugin if you use config plugins in your project (EAS Build or npx expo run:[android|ios]). The plugin allows you to configure various properties that cannot be set at runtime and require building a new app binary to take effect.

Example app.json with config plugin

app.json
{
  "expo": {
    "plugins": [
      [
        "expo-contacts",
        {
          "contactsPermission": "Allow $(PRODUCT_NAME) to access your contacts."
        }
      ]
    ]
  }
}

Configurable properties

NameDefaultDescription
contactsPermission"Allow $(PRODUCT_NAME) to access your contacts"
Only for:
iOS

A string to set the NSContactsUsageDescription permission message.
