 18 | ## Overview
 19 | This document provides instructions on how to install and configure the AWS 
 20 | IoT device/Shadow in React Native.
 21 | 
 22 | ### AWS SDK Dependency
 23 | This package is built on top of the AWS SDK [aws-sdk.js](https://github.com/aws/aws-iot-device-sdk-js) which provides two classes: 'device'
 24 | and 'thingShadow'. 
 25 |  
 26 | #### Thing Shadows
 27 | The 'thingShadow' class implements additional functionality for accessing Thing Shadows via the AWS IoT
 28 | API; the thingShadow class allows devices to update, be notified of changes to,
 29 | get the current state of, or delete Thing Shadows from AWS IoT.  Thing
 30 | Shadows allow applications and devices to synchronize their state on the AWS IoT platform. 
 31 | 
 32 | #### Device
 33 | The 'device' class wraps [mqtt.js](https://github.com/mqttjs/MQTT.js/blob/master/README.md) to provide a
 34 | secure connection to the AWS IoT platform and expose the [mqtt.js](https://github.com/mqttjs/MQTT.js/blob/master/README.md) interfaces upward.  It provides features to simplify handling of intermittent connections, including progressive backoff retries, automatic re-subscription upon connection, and queued offline publishing with configurable drain rate.

 37 | ## Installation
 38 | 
 39 | Installing with npm:
 40 | 
 41 | ```sh
 42 | npm install react-native-aws-iot-device-shadows
 43 | ```
 44 | 
 45 | <a name="examples"></a>
 46 | ## Examples
 47 | 
 48 | ### MQTT React Native IoT Shadow Class
 49 | ```js
 50 | <AWSIoTMQTT
 51 |     ref={(ref) => { this.AWSIoTMQTT = ref; }}
 52 |     type="shadow"
 53 |     region="us-west-2"
 54 |     host="asdasd.iot.aws.com"
 55 |     onReconnect={() => this.onConnect()}
 56 |     onConnect={() => this.onConnect()}
 57 |     onDelta={(thingId, stateObject) => this.onDelta(thingId, stateObject)}
 58 |     onStatus={(thingId, statusType, clientToken, stateObject) =>
 59 |         this.onStatus(thingId, statusType, clientToken, stateObject)}
 60 |     onThingConnected={(thingId) => { this.onThingConnected(thingId); }}
 61 | />
 62 | ```
 63 | 
 64 | ### MQTT React Native IoT device Class
 65 | ```js
 66 | <AWSIoTMQTT
 67 |     ref={(ref) => { this.AWSIoTMQTT = ref; }}
 68 |     type="device"
 69 |     region="us-west-2"
 70 |     host="asdasd.iot.aws.com"
 71 |     onReconnect={() => this.onConnect()}
 72 |     onConnect={() => this.onConnect()} 
 73 | />
 74 | ```
 75 |     
 76 | <a name="AWSIoTMQTT"></a>
 77 | ## AWSIoTMQTT
 78 | 
 79 | Returns a React Native component whichs wraps xxxxxxxx
 80 | 
 81 | 
 82 | <a name="api"></a>
 83 | ## API Documentation
 84 | 
 85 |   * `type`: use 'device' for device type and 'shadows' for ShadowThing
 86 |   * `host`: the AWS IoT endpoint you will use to connect
 87 |   * `region`: the AWS IoT region you will use to connect
 88 |   * `config`: extra configuration for the thingShadow
 89 |   * `onConnect`: callback for when the websockets connects
 90 |   * `onReconnect`: callback for when the websockets reconnects
 91 |   * `onDelta`: callback for delta msg
 92 |   * `onStatus`: callback for status msg
 93 |   * `onThingConnected`: callback for each registered thing
 94 | 
 95 | <a name="connections"></a>
 96 | ## Connection Types
 97 | 
 98 | This react native component only supports one type of connections to the AWS IoT platform:
 99 | 
100 | * MQTT over WebSocket/TLS with SigV4 authentication using port 443
101 | 
102 | 
103 | <a name="debug"></a>
104 | ## Debug
105 | 
106 | The enable debug mode for display logging information just pass a object with debug:true
107 | 
108 | ```js
109 | <AWSIoTMQTT
110 |     config={debug:true}
111 |     ...
112 | />
113 | ```
114 | 
115 | <a name="bundle"></a>
116 | ## Re-Creating the bundle with webpack
117 | This IOT JS SDK is packaged with[webpack](https://webpack.js.org/), because currently there is not official support for AWS IOT react native. This  is already bundle it for you using the last version.
118 | 
119 | ```sh
120 | npm run build
121 | ```
122 | 
123 | <a name="unittests"></a>
124 | ## Unit Tests
125 | 
126 | This package includes unit tests which can be run as follows:
127 | 
128 | ```sh
129 | npm test
130 | ```
131 | 
132 | Running the unit tests will also generate code coverage data in the 'reports'
133 | directory.

 30 | ## Updating to New Releases
 31 | 
 32 | You should only need to update the global installation of `create-react-native-app` very rarely, ideally never.
 33 | 
 34 | Updating the `react-native-scripts` dependency of your app should be as simple as bumping the version number in `package.json` and reinstalling your project's dependencies.
 35 | 
 36 | Upgrading to a new version of React Native requires updating the `react-native`, `react`, and `expo` package versions, and setting the correct `sdkVersion` in `app.json`. See the [versioning guide](https://github.com/react-community/create-react-native-app/blob/master/VERSIONS.md) for up-to-date information about package version compatibility.
 37 | 
 38 | ## Available Scripts
 39 | 
 40 | If Yarn was installed when the project was initialized, then dependencies will have been installed via Yarn, and you should probably use it to run these commands as well. Unlike dependency installation, command running syntax is identical for Yarn and NPM at the time of this writing.
 41 | 
 42 | ### `npm start`
 43 | 
 44 | Runs your app in development mode.
 45 | 
 46 | Open it in the [Expo app](https://expo.io) on your phone to view it. It will reload if you save edits to your files, and you will see build errors and logs in the terminal.
 47 | 
 48 | Sometimes you may need to reset or clear the React Native packager's cache. To do so, you can pass the `--reset-cache` flag to the start script:
 49 | 
 50 | ```
 51 | npm start -- --reset-cache
 52 | # or
 53 | yarn start -- --reset-cache
 54 | ```
 55 | 
 56 | #### `npm test`
 57 | 
 58 | Runs the [jest](https://github.com/facebook/jest) test runner on your tests.
 59 | 
 60 | #### `npm run ios`
 61 | 
 62 | Like `npm start`, but also attempts to open your app in the iOS Simulator if you're on a Mac and have it installed.
 63 | 
 64 | #### `npm run android`
 65 | 
 66 | Like `npm start`, but also attempts to open your app on a connected Android device or emulator. Requires an installation of Android build tools (see [React Native docs](https://facebook.github.io/react-native/docs/getting-started.html) for detailed setup). We also recommend installing Genymotion as your Android emulator. Once you've finished setting up the native build environment, there are two options for making the right copy of `adb` available to Create React Native App:
 67 | 
 68 | ##### Using Android Studio's `adb`
 69 | 
 70 | 1. Make sure that you can run adb from your terminal.
 71 | 2. Open Genymotion and navigate to `Settings -> ADB`. Select “Use custom Android SDK tools” and update with your [Android SDK directory](https://stackoverflow.com/questions/25176594/android-sdk-location).
 72 | 
 73 | ##### Using Genymotion's `adb`
 74 | 
 75 | 1. Find Genymotion’s copy of adb. On macOS for example, this is normally `/Applications/Genymotion.app/Contents/MacOS/tools/`.
 76 | 2. Add the Genymotion tools directory to your path (instructions for [Mac](http://osxdaily.com/2014/08/14/add-new-path-to-path-command-line/), [Linux](http://www.computerhope.com/issues/ch001647.htm), and [Windows](https://www.howtogeek.com/118594/how-to-edit-your-system-path-for-easy-command-line-access/)).
 77 | 3. Make sure that you can run adb from your terminal.
 78 | 
 79 | #### `npm run eject`
 80 | 
 81 | This will start the process of "ejecting" from Create React Native App's build scripts. You'll be asked a couple of questions about how you'd like to build your project.
 82 | 
 83 | **Warning:** Running eject is a permanent action (aside from whatever version control system you use). An ejected app will require you to have an [Xcode and/or Android Studio environment](https://facebook.github.io/react-native/docs/getting-started.html) set up.
 84 | 
 85 | ## Customizing App Display Name and Icon
 86 | 
 87 | You can edit `app.json` to include [configuration keys](https://docs.expo.io/versions/latest/guides/configuration.html) under the `expo` key.
 88 | 
 89 | To change your app's display name, set the `expo.name` key in `app.json` to an appropriate string.
 90 | 
 91 | To set an app icon, set the `expo.icon` key in `app.json` to be either a local path or a URL. It's recommended that you use a 512x512 png file with transparency.
 92 | 
 93 | ## Writing and Running Tests
 94 | 
 95 | This project is set up to use [jest](https://facebook.github.io/jest/) for tests. You can configure whatever testing strategy you like, but jest works out of the box. Create test files in directories called `__tests__` or with the `.test` extension to have the files loaded by jest. See the [the template project](https://github.com/react-community/create-react-native-app/blob/master/react-native-scripts/template/App.test.js) for an example test. The [jest documentation](https://facebook.github.io/jest/docs/getting-started.html) is also a wonderful resource, as is the [React Native testing tutorial](https://facebook.github.io/jest/docs/tutorial-react-native.html).
 96 | 
 97 | ## Environment Variables
 98 | 
 99 | You can configure some of Create React Native App's behavior using environment variables.
100 | 
101 | ### Configuring Packager IP Address
102 | 
103 | When starting your project, you'll see something like this for your project URL:
104 | 
105 | ```
106 | exp://192.168.0.2:19000
107 | ```
108 | 
109 | The "manifest" at that URL tells the Expo app how to retrieve and load your app's JavaScript bundle, so even if you load it in the app via a URL like `exp://localhost:19000`, the Expo client app will still try to retrieve your app at the IP address that the start script provides.
110 | 
111 | In some cases, this is less than ideal. This might be the case if you need to run your project inside of a virtual machine and you have to access the packager via a different IP address than the one which prints by default. In order to override the IP address or hostname that is detected by Create React Native App, you can specify your own hostname via the `REACT_NATIVE_PACKAGER_HOSTNAME` environment variable:
112 | 
113 | Mac and Linux:
114 | 
115 | ```
116 | REACT_NATIVE_PACKAGER_HOSTNAME='my-custom-ip-address-or-hostname' npm start
117 | ```
118 | 
119 | Windows:
120 | ```
121 | set REACT_NATIVE_PACKAGER_HOSTNAME='my-custom-ip-address-or-hostname'
122 | npm start
123 | ```
124 | 
125 | The above example would cause the development server to listen on `exp://my-custom-ip-address-or-hostname:19000`.
126 | 
127 | ## Adding Flow
128 | 
129 | Flow is a static type checker that helps you write code with fewer bugs. Check out this [introduction to using static types in JavaScript](https://medium.com/@preethikasireddy/why-use-static-types-in-javascript-part-1-8382da1e0adb) if you are new to this concept.
130 | 
131 | React Native works with [Flow](http://flowtype.org/) out of the box, as long as your Flow version matches the one used in the version of React Native.
132 | 
133 | To add a local dependency to the correct Flow version to a Create React Native App project, follow these steps:
134 | 
135 | 1. Find the Flow `[version]` at the bottom of the included [.flowconfig](.flowconfig)
136 | 2. Run `npm install --save-dev flow-bin@x.y.z` (or `yarn add --dev flow-bin@x.y.z`), where `x.y.z` is the .flowconfig version number.
137 | 3. Add `"flow": "flow"` to the `scripts` section of your `package.json`.
138 | 4. Add `// @flow` to any files you want to type check (for example, to `App.js`).
139 | 
140 | Now you can run `npm run flow` (or `yarn flow`) to check the files for type errors.
141 | You can optionally use a [plugin for your IDE or editor](https://flow.org/en/docs/editors/) for a better integrated experience.
142 | 
143 | To learn more about Flow, check out [its documentation](https://flow.org/).
144 | 
145 | ## Sharing and Deployment
146 | 
147 | Create React Native App does a lot of work to make app setup and development simple and straightforward, but it's very difficult to do the same for deploying to Apple's App Store or Google's Play Store without relying on a hosted service.
148 | 
149 | ### Publishing to Expo's React Native Community
150 | 
151 | Expo provides free hosting for the JS-only apps created by CRNA, allowing you to share your app through the Expo client app. This requires registration for an Expo account.
152 | 
153 | Install the `exp` command-line tool, and run the publish command:
154 | 
155 | ```
156 | $ npm i -g exp
157 | $ exp publish
158 | ```
159 | 
160 | ### Building an Expo "standalone" app
161 | 
162 | You can also use a service like [Expo's standalone builds](https://docs.expo.io/versions/latest/guides/building-standalone-apps.html) if you want to get an IPA/APK for distribution without having to build the native code yourself.
163 | 
164 | ### Ejecting from Create React Native App
165 | 
166 | If you want to build and deploy your app yourself, you'll need to eject from CRNA and use Xcode and Android Studio.
167 | 
168 | This is usually as simple as running `npm run eject` in your project, which will walk you through the process. Make sure to install `react-native-cli` and follow the [native code getting started guide for React Native](https://facebook.github.io/react-native/docs/getting-started.html).
169 | 
170 | #### Should I Use ExpoKit?
171 | 
172 | If you have made use of Expo APIs while working on your project, then those API calls will stop working if you eject to a regular React Native project. If you want to continue using those APIs, you can eject to "React Native + ExpoKit" which will still allow you to build your own native code and continue using the Expo APIs. See the [ejecting guide](https://github.com/react-community/create-react-native-app/blob/master/EJECTING.md) for more details about this option.
173 | 
174 | ## Troubleshooting
175 | 
176 | ### Networking
177 | 
178 | If you're unable to load your app on your phone due to a network timeout or a refused connection, a good first step is to verify that your phone and computer are on the same network and that they can reach each other. Create React Native App needs access to ports 19000 and 19001 so ensure that your network and firewall settings allow access from your device to your computer on both of these ports.
179 | 
180 | Try opening a web browser on your phone and opening the URL that the packager script prints, replacing `exp://` with `http://`. So, for example, if underneath the QR code in your terminal you see:
181 | 
182 | ```
183 | exp://192.168.0.1:19000
184 | ```
185 | 
186 | Try opening Safari or Chrome on your phone and loading
187 | 
188 | ```
189 | http://192.168.0.1:19000
190 | ```
191 | 
192 | and
193 | 
194 | ```
195 | http://192.168.0.1:19001
196 | ```
197 | 
198 | If this works, but you're still unable to load your app by scanning the QR code, please open an issue on the [Create React Native App repository](https://github.com/react-community/create-react-native-app) with details about these steps and any other error messages you may have received.
199 | 
200 | If you're not able to load the `http` URL in your phone's web browser, try using the tethering/mobile hotspot feature on your phone (beware of data usage, though), connecting your computer to that WiFi network, and restarting the packager.
201 | 
202 | ### iOS Simulator won't open
203 | 
204 | If you're on a Mac, there are a few errors that users sometimes see when attempting to `npm run ios`:
205 | 
206 | * "non-zero exit code: 107"
207 | * "You may need to install Xcode" but it is already installed
208 | * and others
209 | 
210 | There are a few steps you may want to take to troubleshoot these kinds of errors:
211 | 
212 | 1. Make sure Xcode is installed and open it to accept the license agreement if it prompts you. You can install it from the Mac App Store.
213 | 2. Open Xcode's Preferences, the Locations tab, and make sure that the `Command Line Tools` menu option is set to something. Sometimes when the CLI tools are first installed by Homebrew this option is left blank, which can prevent Apple utilities from finding the simulator. Make sure to re-run `npm/yarn run ios` after doing so.
214 | 3. If that doesn't work, open the Simulator, and under the app menu select `Reset Contents and Settings...`. After that has finished, quit the Simulator, and re-run `npm/yarn run ios`.
215 | 
216 | ### QR Code does not scan
217 | 
218 | If you're not able to scan the QR code, make sure your phone's camera is focusing correctly, and also make sure that the contrast on the two colors in your terminal is high enough. For example, WebStorm's default themes may [not have enough contrast](https://github.com/react-community/create-react-native-app/issues/49) for terminal QR codes to be scannable with the system barcode scanners that the Expo app uses.
219 | 
220 | If this causes problems for you, you may want to try changing your terminal's color theme to have more contrast, or running Create React Native App from a different terminal. You can also manually enter the URL printed by the packager script in the Expo app's search bar to load it manually.
