Web5 Wallet

Built with React Native and Expo

Application Setup

Note that most things are not installed using Homewbrew. Homebrew is nice for personal projects but doesn't scale well for teams.

Installation prerequisites:

• nvm (Node Version Manager) - install NOT using homebrew:

  curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

  Change the version in the command above to latest nvm version as needed.

• rvm (Ruby Version Manager) - install NOT using homebrew:

  \curl -sSL https://get.rvm.io | bash -s stable

• node v20.15.1 and select it - install using nvm:

  nvm install 20.15.1

  nvm use 20.15.1 - installing should already switch to the desired version, but run this if node -v shows a wrong version

• ruby v3.2.2 and select it - install using rvm:

  rvm install 3.2.2

  rvm use 3.2.2 - installing should already switch to the desired version, but run this if ruby -v shows a wrong version

  Note, ruby installation requires openSSL v1, if you have openSSL v3 installed, you might need to override with explicit reference to openSSL v1 directory if you installation fails on openSSL. e.g.

  rvm install 3.2.2 --with-openssl-dir=$(brew --prefix openssl@1.1)

• watchman

  brew install watchman

• This project uses the web5-js repo symlinked locally. You must clone the web5-js repo into a sibling folder next to this repo. Afterwards, install and build the web5-js repo.

Installation steps:

1. Run corepack enable to turn on corepack for this node version if you haven't already turned it on.

2. Run corepack install to install yarn pkg manager

3. Run yarn to install node_modules

   Note, if you encounter the following error:

   "Internal Error: Error when performing the request to https://registry.npmjs.org/yarn;
   

   Check to see if you are running a VPN that blocks this URL, if so, disable the VPN and try again.

4. From root repo directory, run:

   cd ios then bundle install

5. From root repo directory, run:

   cd android the bundle install

6. In the root repo directory run yarn pods to install CocoaPods

   Note: if you encounter the error below:

   [!] CocoaPods could not find compatible versions for pod "hermes-engine"
   

   You will need to run the following command to update hermes-engine version in Podfile.lock file in the ios directory as suggested in the full error message:

   pod update hermes-engine --no-repo-update

7. Install XCode with the latest SDK if necessary

8. Install Android Studio with the latest SDK if necessary

The project should now be ready to run.

First start the Metro Bundler:

yarn start

To Run iOS: Inside the ios folder, open the .xcworkspace and run the build (click the "play" button).

To Run Android: Open the android folder in Android Studio and run the build.

Debugging

The application can be debugged through VSCode

1. Download the Expo Tools VSCode Extension.

2. Use the "Run and Debug" menu in VSCode to run the script "Debug Expo App."

3. Fire up a simulator so that the session attaches to the debugger.

4. Set your breakpoints as needed.

   Caution: Reused breakpoints don't work. Make sure to clear breakpoints in between sessions.

Alternative Method

If you are having trouble getting the above method to work. Consider the alternative method below.

Start Metro Bundler with:

npx react-native start --experimental-debugger

Then you can launch the debugger by triggering the Dev Menu in the app (e.g. by pressing d in the Metro Bundler terminal) then choosing the "Open Debugger" option, this will launch the debugger in the browser.

Troubleshooting install

• which yarn should be /Users/{USER}/.yarn/bin/yarn

• which rvm should be /Users/{USER}/.rvm/bin/rvm

• which node should be /Users/{USER}/.nvm/versions/node/v20.15.1/bin/node

• which npm should be /Users/{USER}/.nvm/versions/node/v20.15.1/bin/npm

• nvm list should include -> v20.15.1

• rvm list should include =* ruby-3.2.2 [ arm64 ]

Further troubleshooting install

• Run npx expo-env-info@latest and send that info to a maintainer or post it in an issue
