## Development
This is an Ionic 3 / Angular 5 application using Cordova Plugins for mobile-native functionality.


### dev env setup
For a basic web version, only Node.js 8+ is required.
For Android & iOS builds the respective platform tooling is required.

This repo contains mandatory submodules; so you need to clone this repo via
```sh
git clone --recursive https://github.com/sensebox/blockly-app.git
```

To install npm dependencies run `npm install` once.

Then run `npm start` to start a hot-reloading development view in the browser on <http://localhost:8100>.

Ionic & cordova provide CLIs for plugin installation & code generation. You might want to install them with `npm install -g ionic cordova`.

#### android specific
First install the Android toolchain on your system.

Make sure you have the correct environment variables set.
On linux you could add this to your `~/.bashrc`:
```bash
export ANDROID_SDK=$HOME/Android/Sdk
export ANDROID_HOME=$ANDROID_SDK
export PATH=$PATH:$ANDROID_SDK/emulator:$ANDROID_SDK/tools:$ANDROID_SDK/tools/bin:$ANDROID_SDK/platform-tools:$ANDROID_SDK/build-tools/28.0.3
```

To build & deploy on an emulator or device use the `android:*` build commands defined in `package.json` (some only work on linux), for example:
```bash
npm run android:dev # build debug build & deploy to connected device & restart app
```

###### release signing
You need a keystore with a valid signing key!
```
zipalign -p 4 blockly-unsigned.apk blockly-aligned.apk 
apksigner sign -ks reedu-android.keystore --in blockly-aligned.apk --out blockly-signed.apk
```

### updating blockly

To update it, just pull in the commit you want, and commit the change in this repository:
