ln-extension-executor-bridge

An Expo native module wrapping LNExtensionExecutor. Allows bypassing UIActivityViewController to execute both UI and non-UI action extensions.

Adding to Your Project

1. Create a new Expo native module in your app

   • npx create-expo-module@latest --local ln-extension-executor-bridge

2. Delete all files in modules/ln-extension-executor-bridge:

   • rm -rf modules/ln-extension-executor-bridge/*

3. Clone this repo into the modules/ln-extension-executor-bridge directory. You can delete README.md and LICENSE.

   • cd modules/ln-extension-executor-bridge && git clone https://github.com/carter-0/ln-extension-executor-bridge.git .
   • rm README.md LICENSE

That's it! It's not the most elegent installation and it could definitely be improved by making it a real package but I spent so long getting this to work that I'm not touching it for now.

Usage

Make sure to re-build your app before usage.

Import the module:

import LnExtensionExecutorBridgeModule from "../modules/ln-extension-executor-bridge/src/LnExtensionExecutorBridgeModule"
