Portkey React Native SDK

Read this first

This readme.md doc is presented for pure react-native project. If you are using expo, please refer to expo-sdk-doc.

Don't know whether you are an expo project user? If one of the following conditions is met, you are an expo project user:

you created your project with expo-cli-like command, such as expo init my-project or npx create-expo-app XXX
you can find .expo dictionary in your project root path
you can find those expo's commands in your package.json file that look like:

  "scripts": {
    "start": "expo start",
    "android": "expo run:android",
    "ios": "expo run:ios",
    "web": "expo start --web"
  },
  ...

Installation

Note: react-native's version should be less than v0.73.0 !

Step 1: Install npm package

npm install @portkey/react-native-sdk --save
# or
yarn add @portkey/react-native-sdk

Step 2: Configure your project

Configure the expo autolinking plugin

//in android/settings.gradle file
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.PREFER_SETTINGS)
    repositories {
        google()
        mavenCentral()
        maven { url "https://jitpack.io" }
        // add this maven path for expo-camera dependencies
        maven {
            url "../node_modules/expo-camera/android/maven"
        }
    }
}

// add the follow code for autolink
apply from: new File(["node", "--print", "require.resolve('expo/package.json')"].execute(null, rootDir).text.trim(), "../scripts/autolinking.gradle");
useExpoModules()

# in iOS Podfile, add the follow code

platform :ios, '13.0'

require File.join(File.dirname(`node --print "require.resolve('expo/package.json')"`), "scripts/autolinking")

use_expo_modules!
post_integrate do |installer|
  begin
    expo_patch_react_imports!(installer)
  rescue => e
    Pod::UI.warn e
  end
end

Create .env file
In order to use Google login, You need to create an .env file in the same directory as package.json, which must contain GOOGLE_WEB_CLIENT_ID, GOOGLE_IOS_CLIENT_ID and GOOGLE_ANDROID_CLIENT_ID.
See Configure Google Login For Portkey SDK for details.
```
# .env file like this
GOOGLE_WEB_CLIENT_ID = "your google web client id"
GOOGLE_IOS_CLIENT_ID = "your google ios client id"
GOOGLE_ANDROID_CLIENT_ID = "your google android client id"
```

extends tsconfig.json

In your tsconfig.json, add "extends" key-value.

{
  "extends": "@portkey/react-native-sdk/tsconfig.json",
  "compilerOptions": {
    ...
  }
}

if you already extends other tsconfig.json, you can config like this:

{
  "compilerOptions": {
      // add this code
      "types": ["reflect-metadata"],
      "experimentalDecorators": true,
      "emitDecoratorMetadata": true,
  }

}

deal with the version gap
Since both our SDK project and your project are using particular versions of several dependencies that are common in react-native development, there may be version conflicts, which will cause runtime errors.
For example, if your project is using react-native version 0.63.4, but our SDK project is using react-native version 0.63.3, then there will be a version conflict. The only way to stop this conflict is to make sure that both projects are using the same version of react-native.
You can solve this problem by those instructions:
a. check the SDK's dependencies
Please refer to the package.json file in the dictionary of <Your Project Root>/node_modules/@portkey/react-native-sdk, and check the dependencies' and 'devDependencies' field. You can ignore those dependencies marked with "peerDependencies" since they have no version code.
b. check your project's dependencies and compare
Check your project's package.json file, and compare the dependencies' and 'devDependencies' field with the SDK's. Record the version code of those dependencies that are different from the SDK's.
c. make a decision
We recommend you to use the same version of conflicting dependencies as the SDK's. You can do that by changing your project's dependencies' version code to the SDK's version code.
But if for some reason you can't do that, you can try to use your project's version code and make the SDK's version code the same as yours. But this may cause some unexpected errors.
You can use the resolutions field or overrides field in your project's package.json file to solve this problem. the resolutions field will only work on yarn, and the overrides field will only work on npm (although they all looks the same).
```
{
  "dependencies": {
    "react-native": "0.63.4", // and SDK is using 0.63.3
    ...
  },

  // use resolutions field for yarn
  "resolutions": {
    "react-native": "0.63.3"
  },

  // use overrides field for npm
  "overrides": {
    "react-native": "0.63.3"
  }
}
```
This will force the react-native version to be 0.63.3, which is the same as the SDK's.
To make sure there are no other version conflicts, you can check that there are no matching dependencies under <Your Project Root>/node_modules/@portkey/react-native-sdk/node_modules, since dependency conflicts will make a different version of the same dependency coexists in there.

Step 3: Init

// Please import the following statement in your entry file
import '@portkey/react-native-sdk';

Note: We use autolink, you don't need to configure Android/iOS dependencies. But you need to recompile your Android/iOS project so that the autolink takes effect.

Now, all configuration is complete and you can use the portkey service freely.

Q&A

Q: Why does Google login always prompt "login fail"?

A: Make sure the applicationId, keystore, .env file correspond correctly.

Q: problem occurred evaluating project ':portkey_react-native-sdk'. > Project with path ':expo-modules-core' could not be found in project ':portkey_react-native-sdk'.

A: make sure you have set the expo autolink config in android/settings.gradle file.
