How to Set Up Import Aliases for Gatsby

In this post, we will be looking into how we can add import aliases to our gatsby site step by step.

The reason why we are setting up import aliases is more to do about readability and the look of our code when importing components from the import tree.

What I mean by that, is if we look at the following example

import Subscribe from '../../../../../../../core/modules/newsletter/mixins/Subscribe'

This just looks downright ugly in my opinion, so how can we improve it?

We can do that by updating webpack config to include aliases for our main directories that we know are going to be the base for our components.

Once we go through all the steps from this post, the end results will look like the following below

import Subscribe from '@core/modules/newsletter/mixins/Subscribe'

---

Adding Aliases in Gatsby

Given that Gatsby uses Webpack as its core and does not expose the config by default, we can add custom Webpack config using Gatsby’s onCreateWebpackConfig API, this will result in the custom configs being merged allowing you to modify the default webpack config.

To add the custom webpack config we need to edit (or create the file if it doesn’t exist in the root of our project) gatsby-node.js and add the new configs into it.

Configuration

const path = require("path");
exports.onCreateWebpackConfig = ({ actions }) => {
  actions.setWebpackConfig({
    resolve: {
      alias: {
        "@components": path.resolve(__dirname, "src/components"),
        "@static": path.resolve(__dirname, "static")
      }
    }
  });
}

As we can see in the above snippet, actions object give us the option to use setWebpackConfig that takes our custom webpack config and merge it to Gatsby’s webpack config.

In order to add new aliases, we are going to use webpack’s resolve alias which will allow us to use the newly created import aliased inside our components.

As you can see below, the end result after adding the new alias will look like this

import Layout from '@components/Layout';

WebEngage Flutter Plugin

WebEngage Flutter SDK

For more information checkout our website and documentation.

Installation

Add WebEngage Flutter Plugin

• Add webengage_flutter in your pubspec.yaml file.

dependencies:
webengage_flutter: 1.0.3

• Run flutter packages get to install the SDK

Initialization

Android

1. Initialize WebEngage in main.dart in initState();

WebEngagePlugin _webEngagePlugin = new WebEngagePlugin();

1. Initialize WebEngage Android SDK in your <your-project>/android/app/src/main/java/<your-package-path>/MainApplication.java class.

...
import com.webengage.sdk.android.WebEngageActivityLifeCycleCallbacks;
import io.flutter.app.FlutterApplication;

public class MainApplication extends FlutterApplication {
    @Override
    public void onCreate() {
        super.onCreate();
         WebEngageConfig webEngageConfig = new WebEngageConfig.Builder()
                .setWebEngageKey("YOUR_LICENCSE_CODE")
                .setAutoGCMRegistrationFlag(false)
                .setLocationTrackingStrategy(LocationTrackingStrategy.ACCURACY_BEST)
                .setDebugMode(true) // only in development mode
                .build();
        WebengageInitializer.initialize(this,webEngageConfig);
        ...
    }
    ...
}

Push Notifications

1. Add below dependencies in app-level build gradle

    implementation platform('com.google.firebase:firebase-bom:25.12.0')
    implementation 'com.google.firebase:firebase-analytics'
    implementation 'com.google.firebase:firebase-messaging:20.2.1'
    implementation 'com.google.android.gms:play-services-ads:15.0.1'

1. Add the following to your dependencies section in project/build.gradle

        classpath 'com.google.gms:google-services:4.3.4'

1. Firebase tokens can be passed to WebEngage using FirebaseMessagingService

import com.google.firebase.messaging.FirebaseMessagingService;
import com.webengage.sdk.android.WebEngage;

public class MyFirebaseMessagingService extends FirebaseMessagingService {
    @Override
    public void onNewToken(String s) {
        super.onNewToken(s);
        WebEngage.get().setRegistrationID(s);
    }
}

It is also recommended that you pass Firebase token to WebEngage from onCreate of your Application class as shown below. This will ensure that changes in user’s Firebase token are communicated to WebEngage.

import com.google.android.gms.tasks.OnSuccessListener;
import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.InstanceIdResult;
import com.webengage.sdk.android.WebEngage;

public class MainApplication extends FlutterApplication {
    @Override
    public void onCreate() {
        super.onCreate();
    FirebaseMessaging.getInstance().getToken()
    .addOnCompleteListener(new OnCompleteListener<String>() {
        @Override
        public void onComplete(@NonNull Task<String> task) {
          if (!task.isSuccessful()) {
            Log.w(TAG, "Fetching FCM registration token failed", task.getException());
            return;
          }
          // Get new FCM registration token
          String token = task.getResult();
          WebEngage.get().setRegistrationID(token);
        }
    });
     
    }
}

1. Pass Messages to WebEngage Create a class that extends FirebaseMessagingService and pass messages to WebEngage. All incoming messages from WebEngage will contain key source with the value as webengage.

package your.application.package;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
import com.webengage.sdk.android.WebEngage;

public class MyFirebaseMessagingService extends FirebaseMessagingService {
  @Override
  public void onMessageReceived(RemoteMessage remoteMessage) {
    Map<String, String> data = remoteMessage.getData();
    if(data != null) {
      if(data.containsKey("source") && "webengage".equals(data.get("source"))) {
        WebEngage.get().receive(data);
      }
    }
  }
}

Next, register the service to the application element of your AndroidManifest.xml as follows.

<service
    android:name=".MyFirebaseMessagingService">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>

iOS

1. Add WebEngage configurations <your-project>/ios/<YourApp>/Info.plist file.

<dict>
	<key>WEGLicenseCode</key>
	<string>YOUR-WEBENGAGE-LICENSE-CODE</string>

	<key>WEGLogLevel</key>
	<string>VERBOSE</string>
    ...
</dict>

1. Initialize WebEngage iOS SDK in <your-project>/ios/<YourApp>/AppDelegate.m file.

#import <WebEngage/WebEngage.h>
...

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary * launchOptions {
    ...
  
    [[WebEngage sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];

How Imports Work in Python

And a bit about packages

The Python import system is pretty straightforward… to a point. Importing code present in the same directory you’re working in is very different from importing between multiple files present in multiple directories. Through this post, I try to analyse the different import scenarios that one might encounter, hopefully making it easier to create your own packages.

The Growing Need and Importance of Data Enrichment

Organizations can make progress by enriching their customer data to improve their customer experience.

As 2021 initiates, customers have sky-high expectations with regards to their experiences with each business they associate with: retail brands, utility services, and even their banks. It’s anticipated that these organizations should envision our necessities, know what our identity is, and consistently be important. Basically, we need organizations to read our thoughts. While this is incomprehensible and unreasonable, organizations can make progress by enriching their customer data to improve their customer experience.

Having access to the same volunteered data your rivals have, you don’t have a lot of favorable advantages over them. To improve and get more profound information, you can utilize data enrichment.

Data enrichment is a process that can transform the data you have into a total profile that precisely maps the requirements of your leads.

Why Data Enrichment?
