# Embassy App

Only Android right now, under heavy development

#### Requirements

Install `nodejs v18`

#### Installation

```bash
yarn
```

#### Add circuit build

Go to this [repo](https://github.com/0xturboblitz/circom-embassy) and build the circuit.
Then, place `passport.r1cs` and `passport.wasm` in ark-circom-passport/passport/

#### Build native lib

In /script, run:
```
./build_rust.sh
```
This will build the libhalo2_circom_passport.so lib and copy it to the desired place to be used by the app.
The config used is in android/react-native-passport-reader/android/build.gradle.
You can go there to change the profile (`debug` or `release`)



You'll potentially need to set the rust-toolchain rust version as global default. Example:
```
rustup default 1.67.0
```
And install the targets like this:
```
rustup target add aarch64-linux-android
```

To run the server:
```
yarn start
```
Then press `a` for android or `i` for iOS









This is a new [**React Native**](https://reactnative.dev) project, bootstrapped using [`@react-native-community/cli`](https://github.com/react-native-community/cli).

# Getting Started

>**Note**: Make sure you have completed the [React Native - Environment Setup](https://reactnative.dev/docs/environment-setup) instructions till "Creating a new application" step, before proceeding.

## Step 1: Start the Metro Server

First, you will need to start **Metro**, the JavaScript _bundler_ that ships _with_ React Native.

To start Metro, run the following command from the _root_ of your React Native project:

```bash
# using npm
npm start

# OR using Yarn
yarn start
```

## Step 2: Start your Application

Let Metro Bundler run in its _own_ terminal. Open a _new_ terminal from the _root_ of your React Native project. Run the following command to start your _Android_ or _iOS_ app:

### For Android

```bash
# using npm
npm run android

# OR using Yarn
yarn android
```

### For iOS

```bash
# using npm
npm run ios

# OR using Yarn
yarn ios
```

If everything is set up _correctly_, you should see your new app running in your _Android Emulator_ or _iOS Simulator_ shortly provided you have set up your emulator/simulator correctly.

This is one way to run your app — you can also run it directly from within Android Studio and Xcode respectively.

## Step 3: Modifying your App

Now that you have successfully run the app, let's modify it.

1. Open `App.tsx` in your text editor of choice and edit some lines.
2. For **Android**: Press the <kbd>R</kbd> key twice or select **"Reload"** from the **Developer Menu** (<kbd>Ctrl</kbd> + <kbd>M</kbd> (on Window and Linux) or <kbd>Cmd ⌘</kbd> + <kbd>M</kbd> (on macOS)) to see your changes!

   For **iOS**: Hit <kbd>Cmd ⌘</kbd> + <kbd>R</kbd> in your iOS Simulator to reload the app and see your changes!

## Congratulations! :tada:

You've successfully run and modified your React Native App. :partying_face:
