Drawings, gestures, and animations workshop – App.js Conference 2022

Hosted by


During this workshop we will work with an Expo / React Native app published in this repo. In order to make setup more seamless we have prepared a so-called Expo’s development client builds that include all the native code for all the dependencies that are used as a part of the workshop.

You should be able to use iOS simulator, Android emulator, or any modern Andorid or iOS phone to perform the exercises, however, we recommend that you stick to one choice to avoid additional setup steps you may need to do in the future. If you choose to work with an emulator (either iOS or Android) make sure that you have that emulator installed and configured as setting it up is outside of this setup scope.

Before you begin

use the below command to install Expo CLI:

npm install -g expo-cli

Or make sure it is up to date if you have it installed already:

expo --version

Preparing device or simulator

Depending on what device or simulator you choose to use, you’ll need to install custom made Development Client application in your environment. Follow one of the sections below for detailed instructions.

For iOS simulator

  1. Download Development Client build from this link
  2. Extract appjsworkshop.app file from the downloaded archive
  3. Launch your iOS simulator
  4. Drag and drop the .app file onto the simulator

Running the app

After completing Development Client installation step, you now should be able to clone this repo and launch the app. Follow the below steps from the terminal:

git clone [email protected]:software-mansion-labs/drawings-and-animations-workshop.git && cd drawings-and-animations-workshop
  1. Install project dependencies (run the below command from the project main directory):
