@huyhpham/rn-line v1.0.0

This library includes:

• LINE SDK v5 for iOS Swift, wrapped with Swift.
• LINE SDK v5 for Android, wrapped with Kotlin.

Requirements

• React native >=0.61.1
• iOS 10.0 or later as the development target
• Android minSdkVersion set to 17 or higher
• LINE developer account with a channel created.

Migration from v1.x.x

If you are currently using react-native-line-sdk (v1.x.x):

1. Unlink the old library:

  react-native unlink react-native-line-sdk

2. Remove it from the package.json
3. Remove any line sdk's *.aar from android/libs
4. Remove from android/app/build.gradle:

repositories {
    flatDir {
        dirs 'libs'
    }
}

Finally, follow the installation steps for the new version.

Installation

First, install the npm package with yarn. Autolink is automatic.

  yarn add @xmartlabs/react-native-line

iOS Setup

Using Objective-C

Inside your AppDelegate.m, setup the line sdk by passing the channel id obtained.

1. Add platform :ios, '10.0' in Podfile line:1
2. Modify your info.plist like it says here Configuring the Info.plist file
3. Change your AppDelegate.m to match the following:

// AppDelegate.m

//
// Import the Library
//
@import RNLine;

//
// Setup the plugin using your CHANNEL_ID when the app finishes launching
//
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [LineLogin setupWithChannelID:@"YOUR_CHANNEL_ID" universalLinkURL:nil];
}

//
// Handle redirection back to the app from Line
//
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  return [LineLogin application:app open:url options:options];
}

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray<id<UIUserActivityRestoring>> * _Nullable))restorationHandler
{
  BOOL handledLine = [LineLogin application:application continue:userActivity restorationHandler:restorationHandler];
  return handledLine;
}

Using Swift

1. Follow instructions in Integrating LINE Login with your iOS app.
2. Change your AppDelegate.m to match the following:

// AppDelegate.swift

//
// Import the Library
//
import LineLogin

//
// Setup the plugin using your CHANNEL_ID when the app finishes launching
//
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    LineLogin.setup(channelID: "YOUR_CHANNEL_ID", universalLinkURL: nil)

    return true
}

//
// Handle redirection back to the app from Line
//
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    return LineLogin.application(app, open: url, options: options)
}

Don't forget to add application function, as line's instructions indicate.

Android Setup

1. Follow all the configuration steps in Line's Android integration guide
2. Add the string line_channel_id to your strings file with the the channel id that you have on your line console.

<string name="line_channel_id" translatable="false">Your channel id here</string>

3. Add minSdkVersion = 17 in android/build.gradle
4. Add LineSDK as a dependency in android/build.gradle

android {
  // Enable Java 1.8 support.
  compileOptions { // <- add this block if didn't setup
      sourceCompatibility JavaVersion.VERSION_1_8
      targetCompatibility JavaVersion.VERSION_1_8
  }
  ...
  dependencies {
    ...
    implementation 'com.linecorp.linesdk:linesdk:5.7.0' // <- add this line
  }
}

5. In your manifest add xmlns:tools="http://schemas.android.com/tools" in your manifest tag and also tools:replace="android:allowBackup" in your application tag

API

First, require the LineLogin module:

import LineLogin from '@xmartlabs/react-native-line'

Then, you can start using all the functions that are available:

Return values

The following objects are returned on the methods described above:

1. UserProfile:

{
   /// The user ID of the current authorized user.
  userID: String

  /// The display name of the current authorized user.
  displayName: string

  /// The profile image URL of the current authorized user. `null` if the user has not set a profile
  /// image.
  pictureURL?: string

  /// The status message of the current authorized user. `null` if the user has not set a status message.
  statusMessage?: string
}

2. AccessToken:

{
   /// The value of the access token.
  access_token: String
  /// The expiration time of the access token. It is calculated using `createdAt` and the validity period
  /// of the access token. This value might not be the actual expiration time because this value depends
  /// on the system time of the device when `createdAt` is determined.
  expires_in: String
  /// The raw string value of the ID token bound to the access token. The value exists only if the access token
  /// is obtained with the `.openID` permission.
  id_token?: String
}

3. AccessTokenVerifyResult:

{
  // The channel ID bound to the access token.
  client_id: String

  /// The amount of time until the access token expires.
  expires_in: String

  /// Valid permissions of the access token separated by spaces
  scope: String
}

4. LoginResult

{
   /// The access token obtained by the login process.
  accessToken: AccessToken
  /// The permissions bound to the `accessToken` object by the authorization process. Scope has them separated by spaces
  scope: String
  /// Contains the user profile including the user ID, display name, and so on. The value exists only when the
  /// `.profile` permission is set in the authorization request.
  userProfile?: UserProfile
  /// Indicates that the friendship status between the user and the bot changed during the login. This value is
  /// non-`null` only if the `.botPromptNormal` or `.botPromptAggressive` are specified as part of the
  /// `LoginManagerOption` object when the user logs in. For more information, see Linking a bot with your LINE
  /// Login channel at https://developers.line.me/en/docs/line-login/web/link-a-bot/.
  friendshipStatusChanged?: boolean
  /// The `nonce` value when requesting ID Token during login process. Use this value as a parameter when you
  /// verify the ID Token against the LINE server. This value is `null` if `.openID` permission is not requested.
  IDTokenNonce?: String
}

5. BotFriendshipStatus

{
  friendFlag: boolean
}

  /// URL in the login response.
  PROFILE = 'profile',

        ...
    } catch (error) {
        ...
    }

2. Login with arguments:

    try {
        ...
        const loginResult = await Line.login({
          scopes: ['email', 'profile'],
          botPrompt: 'normal'
        })
        ...
    } catch (error) {
