Usage (creating an example app)

Expo package

yarn global add expo-cli
# expo-cli supports following Node.js versions:
# * >=8.9.0 <9.0.0 (Maintenance LTS)
# * >=10.13.0 <11.0.0 (Active LTS)
# * >=12.0.0 (Current Release)
expo init StreamChatExpoExample
cd StreamChatExpoExample
yarn add stream-chat-expo

Please check Example to see usage of the components.

OR you can swap this file for your App.js in the root folder with additional following steps:

yarn add react-navigation

and finally

yarn start

Native package:

For react native < 0.60

react-native init StreamChatReactNativeExample
cd StreamChatReactNativeExample
yarn add stream-chat-react-native

# https://github.com/react-native-community/react-native-netinfo#react-native-compatibility
# For React native 0.59.x - use @react-native-community/[email protected]
# For React native <= 0.58.x - use @react-native-community/[email protected]
yarn add @react-native-community/[email protected]

# https://github.com/react-native-community/react-native-image-picker#react-native-compatibility
yarn add [email protected]
yarn add react-native-document-picker

react-native link @react-native-community/netinfo

# if you are plannign to use image picker or file picker or both
react-native link react-native-image-picker
react-native link react-native-document-picker

Please check Example to see usage of components.

OR you can swap this file for your App.js in root folder with additional following steps:

yarn add [email protected]
yarn add [email protected] react-native-reanimated
react-native link react-native-gesture-handler
react-native link react-native-reanimated

and finally

react-native run-ios

For react native >= 0.60

react-native init StreamChatReactNativeExample
cd StreamChatReactNativeExample
yarn add stream-chat-react-native
yarn add @react-native-community/netinfo react-native-image-picker react-native-document-picker
cd ios && pod install && cd ..

Just to be sure, please verify you are using appropriate version of following packages as per your react-native version.

• netinfo : https://github.com/react-native-community/react-native-netinfo#react-native-compatibility

• react-native-image-picker : https://github.com/react-native-community/react-native-image-picker#react-native-compatibility

Please check Example to see usage of components.

OR you can swap this file for your App.js in root folder with additional following steps:

yarn add [email protected]
yarn add react-native-gesture-handler react-native-reanimated
cd ios && pod install && cd ..

and finally

iOS:

react-native run-ios

Note for Android:

If you are using androidx app:

AndroidX is a major step forward in the Android ecosystem, and the old support library artifacts are being deprecated. For 0.60, React Native has been migrated over to AndroidX. This is a breaking change, and your native code and dependencies will need to be migrated as well.

(reference: https://facebook.github.io/react-native/blog/2019/07/03/version-60#androidx-support)

In current context, dependencies such as react-native-document-picker and (if you are using react-navigation) react-native-gesture-handler, react-native-reanimated don't have androidx support. But awesome tool named jetifier is quite usefull to patch these dependencies with androidx support.

NOTE If you are planning to use file picker functionality, make sure you enable iCloud capability in your app

Upgrade

• Upgrade from 0.1.x to 0.2.x:

  • 0.2.x added support for react native 0.60. Dependencies like react-native-image-picker, react-native-document-picker and netinfo have been taken out of hard dependencies and moved to peer dependencies and thus will have to be installed manually on consumer end (Reference)

  • React native 0.60 came with autolinking functionality, that means if some native libraries are linked manually before upgrade, they will have to be unliked so that react native can autolink them (Reference)

    react-native unlink react-native-image-picker
    react-native unlink react-native-document-picker
    react-native unlink @react-native-community/netinfo

  • React native 0.60 has been migrated over to AndroidX. In current context, dependencies such as react-native-document-picker and (if you are using react-navigation) react-native-gesture-handler, react-native-reanimated don't have androidx support. But awesome tool named jetifier is quite usefull to patch these dependencies with androidx support.

  • CocoaPods are not part of React Native's iOS project (ref). Thus make sure to install all the pod dependencies.

    cd ios && pod install && cd ..

How to run example

Expo example

1. Make sure node version is >= v10.13.0

2. yarn global add expo-cli
   git clone https://github.com/GetStream/stream-chat-react-native.git
   cd stream-chat-react-native
   make
   cd examples/one
   yarn start

Native example

1. Please make sure you have installed necessary dependencies depending on your development OS and target OS. Follow the guidelines given on official react native documentation for installing dependencies: https://facebook.github.io/react-native/docs/getting-started#

2. Make sure node version is >= v10.13.0

3. Start the simulator

4. git clone https://github.com/GetStream/stream-chat-react-native.git
   cd stream-chat-react-native
   make
   cd examples/two

5. • For iOS

     react-native run-ios

   • For android

     react-native run-android

While running native example, you may (not necessarily) run into following issues:

1. When you execute react-native run-ios for the first time, it starts a metro bundler in parallel. It can result into some errors, since build process isn't complete yet. Try the following to fix this:

   1. Close/stop the metro bundler process.
   2. Let the build process finish completely, it can take usually around 2-3 minutes for the first time.
   3. Start the metro bundler manually by executing yarn start inside stream-chat-react-native/examples/two directory.

2. When you execute react-native run-android, you may (not necessarily) run into following error:

   info Starting JS server...
   info Building and installing the app on the device (cd android && ./gradlew app:installDebug)...
   Starting a Gradle Daemon, 1 incompatible Daemon could not be reused, use --status for details
   
   FAILURE: Build failed with an exception.
   
   * What went wrong:
   A problem occurred configuring project ':@react-native-community_netinfo'.
   > SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.
   
   * Try:
   Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
   
   * Get more help at https://help.gradle.org
   
   BUILD FAILED in 13s
   error Could not install the app on the device, read the error above for details.
   Make sure you have an Android emulator running or a device connected and have
   set up your Android development environment:
   https://facebook.github.io/react-native/docs/getting-started.html
   error Command failed: ./gradlew app:installDebug. Run CLI with --verbose flag for more details.

   To resolve this, do the following

   1. Craete a file named local.properties inside stream-chat-react-native/examples/two/android directory
   2. Put the this line in that file. Make sure sdk path is correctly mentioned as per your system:

      sdk.dir=/Users/{user_name}/Library/Android/sdk/

   3. Rerun react-native run-android in stream-chat-react-native/examples/two directory
