Third-party expo plugins


Add third-party plugins to your React Native projects. WaveMaker extended support for npm, git, and local, in addition to Expo plugins. You can import plugins from the Export as ReactNative Zip Dialog.

Expo

This option shows all the available Expo plugins. Once the plugin is selected, it will add the latest version of the plugin to the project.

Expo-plugins

Npm

This option will allow users to add a specified version of the plugin from the npm registry and add it to the project.

Expo-plugins-npm

GitHub

This option allows you to upload custom expo plugins from the Git repo. For this, provide the plugin name and the Git repository details, such as github:username/repository and it will get added to the project.

GitHub Example

Git Repo URL - https://github.com/sboyina/my-expo-battery

You'll need to pass the GitHub URL: https://github.com/sboyina/my-expo-battery/tarball/main

Expo-plugins-git

Local

This option allows users to upload their own customized plugin using tarball file (.tgz file).

You can get the tarball (.tgz file) of expo-plugins by visiting https://registry.npmjs.org/expo-plugin-name/expo-plugin-version

You can find the tarball under the dist key.

Expo-plugins-local

Script

const Battery = require('expo-battery');

Page.onReady = function() {
Page.batteryLevel();
};

Page.batteryLevel = async function() {
const batteryLevel = await Battery.getBatteryLevelAsync();
Page.Widgets.label3.caption = batteryLevel;
}
  1. Preview will show the Battery Level using getBatteryLevelAsync API.

Platform

Third-party plugins are supported only on specific platforms and these can be implemented by using Platform.OS. By importing react-native a condition to check the platform can be added. See the example below.

const Battery = require('expo-battery');
const reactnative = require('react-native');
Page.onReady = function() {
if (reactnative.Platform.OS == 'web')
Page.batteryLevel();
};

Page.batteryLevel = async function() {
const batteryLevel = await Battery.getBatteryLevelAsync();
Page.Widgets.label3.caption = batteryLevel;
}
