How can you develop a Banking App that balances security with UX? 

While all other industries are leveraging the capability of mobile apps to streamline operations and enhance end-user experiences, the banking sector is no exception. Today, banking applications have become part and parcel of personal finance management, offering convenience and accessibility to users. Banking app development requires a blend of robust security measures and seamless UX to meet industry standards and end-user expectations. The entire process involves several key aspects including secure user authentication, data encryption, and user-friendly design.

Developing a banking app that balances security with user experience is challenging but achievable. This post provides you with step-by-step guidance on how to create a simple banking app (MVP) with basic functionalities like user authentication, secure data communication, and balance checking.  

Banking App Development: An example 

Prerequisites  

Tech Stack: React Native for mobile app development, Firebase for backend services, and AES for data encryption. 

Tools: Firebase Authentication, React Navigation, Axios for API calls. 

Key Development Steps 

Step 1: Set Up Firebase Authentication 

Firebase Authentication will handle user sign-up, sign-in, and multi-factor authentication (MFA). 

Install Firebase 

npm install firebase 

Then, create a Firebase configuration file (firebaseConfig.js):  

import firebase from "firebase/app"; 

import "firebase/auth"; 

const firebaseConfig = { 

  apiKey: "YOUR_API_KEY", 

  authDomain: "YOUR_AUTH_DOMAIN", 

  projectId: "YOUR_PROJECT_ID", 

  storageBucket: "YOUR_STORAGE_BUCKET", 

  messagingSenderId: "YOUR_MESSAGING_SENDER_ID", 

  appId: "YOUR_APP_ID", 

}; 

if (!firebase.apps.length) { 

  firebase.initializeApp(firebaseConfig); 

} else { 

  firebase.app(); 

} 

export default firebase; 

Create the sign-up and login functions in the banking application 

import firebase from './firebaseConfig'; 

export const signUp = async (email, password) => { 

  try { 

    await firebase.auth().createUserWithEmailAndPassword(email, password); 

  } catch (error) { 

    console.error(error.message); 

  } 

}; 

export const login = async (email, password) => { 

  try { 

    await firebase.auth().signInWithEmailAndPassword(email, password); 

  } catch (error) { 

    console.error(error.message); 

  } 

}; 

Step 2: Implement Data Encryption with AES 

Data encryption is essential for securing user data. AES (Advanced Encryption Standard) will be used to encrypt and decrypt sensitive information. 

Install the crypto library for AES encryption: 

npm install crypto-js 

How to encrypt and decrypt sensitive data? 

import CryptoJS from 'crypto-js'; 

// Encryption function 

export const encryptData = (data, secretKey) => { 

  return CryptoJS.AES.encrypt(data, secretKey).toString(); 

}; 

// Decryption function 

export const decryptData = (encryptedData, secretKey) => { 

  const bytes = CryptoJS.AES.decrypt(encryptedData, secretKey); 

  return bytes.toString(CryptoJS.enc.Utf8); 

}; 

Step 3: Fetch User Balance Using Axios 

Let’s assume you have a backend API that returns the user's balance. Here, Axios can be used to fetch the data securely. 

Install Axios 

npm install axios 

Then, fetch the User balance from an API 

import axios from 'axios'; 

export const getBalance = async (userId) => { 

  try { 

    const response = await axios.get(`https://api.example.com/balance/${userId}`, { 

      headers: { 

        'Authorization': `Bearer ${userToken}`, // Use token from Firebase 

      }, 

    }); 

    return response.data.balance; 

  } catch (error) { 

    console.error(error.message); 

  } 

}; 

Step 4: User Interface to Display Balance 

Create a simple interface for displaying the user's balance. 

import React, { useState, useEffect } from 'react'; 

import { Text, View, Button } from 'react-native'; 

import { getBalance } from './api'; 

const BalanceScreen = () => { 

  const [balance, setBalance] = useState(null); 

  const userId = "USER_ID";  // Replace with the actual user ID 

  useEffect(() => { 

    const fetchBalance = async () => { 

      const userBalance = await getBalance(userId); 

      setBalance(userBalance); 

    }; 

    fetchBalance(); 

  }, []); 

  return ( 

    <View> 

      <Text>Your Current Balance: {balance}</Text> 

      <Button title="Refresh Balance" onPress={() => fetchBalance()} /> 

    </View> 

  ); 

}; 

export default BalanceScreen; 

Step 5: Secure the API Requests 

Make sure that your API endpoints use HTTPS (SSL/TLS) to establish secure communication. If you're developing the backend yourself, you can use libraries like Express and Helmet to enforce HTTPS and security headers. 

How to set up secure headers in Express? 

npm install express helmet 

const express = require('express'); 

const helmet = require('helmet'); 

const app = express(); 

// Use Helmet to secure HTTP headers 

app.use(helmet()); 

app.get('/balance/:userId', (req, res) => { 

  // Endpoint logic to return user balance 

  res.json({ balance: '1000.00' }); 

}); 

app.listen(3000, () => { 

  console.log('Server running on port 3000'); 

}); 

Summing it Up 

By adopting these best practices—secure authentication, data encryption, and secure API communication—you can craft a banking app that protects user data while delivering an intuitive, engaging experience. This example provides the basic steps to get started with developing a secure and user-friendly banking app. You can build upon this foundation by adding advanced features such as transaction history, real-time notifications, and more advanced security measures such as two-factor authentication depending upon your specific needs.

Integrating Redux Toolkit into Your React TypeScript App: A Comprehensive Guide

It is essential to keep up with the latest tools and technologies in the field of front-end web development. One such tool that has gained popularity among developers is Redux Toolkit. Redux Toolkit is a package that simplifies the process of managing state in React applications, especially when using TypeScript.

In this blog, we'll guide you through the process of integrating the Redux Toolkit into your React TypeScript app, ensuring a smoother and more efficient development experience.

What is Redux Toolkit?

Redux Toolkit is a package that provides a set of tools and best practices for managing state in Redux applications. It includes utilities such as configureStore, which simplifies the setup of a Redux store, as well as createSlice, which allows you to define Redux slices with less boilerplate code. Redux Toolkit also includes middleware such as redux-thunk, which enables you to write asynchronous logic in your Redux reducers.

Benefits for Developers and Users:

Simplified State Management:

Redux Toolkit simplifies state management, ensuring a more predictable application state for a smoother user experience.

Improved Code Organization:

Encourages a structured approach to code organization, enhancing readability and maintainability.

Enhanced Debugging:

Includes Redux DevTools for real-time inspection and debugging of state changes.

Streamlined Asynchronous Actions:

Simplifies handling of asynchronous actions like API calls, improving performance.

Scalability:

Designed to scale with the application's complexity, maintaining performance and maintainability.

Type Safety:

Provides TypeScript integration for type safety, reducing runtime errors, and improving code quality.

Step 1: Installing Redux Toolkit

The first step in integrating the Redux Toolkit into your React TypeScript app is to install the package. You can use npm or yarn for this:

npm install @reduxjs/toolkit

or

yarn add @reduxjs/toolkit

Step 2: Setting Up the Redux Store

Next, you'll need to set up the Redux store in your application. Create a new file called store.ts and define your Redux store using the ‘configureStore’ function from Redux Toolkit:

import { configureStore } from '@reduxjs/toolkit';

import rootReducer from './reducers';

const store = configureStore({

  reducer: rootReducer,

});

export default store;

Step 3: Creating Redux Slices

Redux Toolkit allows you to define Redux slices using the createSlice function. A slice is a collection of Redux reducers and actions that are related to a specific feature or part of your application. Here's an example of how you can create a slice for managing a user's authentication state:

import { createSlice } from '@reduxjs/toolkit';

const authSlice = createSlice({

  name: 'auth',

  initialState: {

    isAuthenticated: false,

    user: null,

  },

  reducers: {

    login(state, action) {

      state.isAuthenticated = true;

      state.user = action.payload;

    },

    logout(state) {

      state.isAuthenticated = false;

      state.user = null;

    },

  },

});

export const { login, logout } = authSlice.actions;

export default authSlice.reducer;

Step 4: Connecting Redux to Your React Components

Finally, you'll need to connect your Redux store to your React components using the Provider component from the react-redux package. Use the Provider component to wrap your root component and pass your Redux store as a prop:

import React from 'react';

import ReactDOM from 'react-dom';

import { Provider } from 'react-redux';

import store from './store';

import App from './App';

ReactDOM.render(

  <Provider store={store}>

    <App />

  </Provider>,

  document.getElementById('root')

);

Integrating the Redux Toolkit into your React TypeScript app can help you manage state more effectively and improve the overall development experience. By following the steps outlined in this guide, you'll be able to seamlessly integrate Redux Toolkit into your app and take advantage of its powerful features. Remember to stay updated with the latest developments in front-end web development, as new tools and technologies are constantly emerging.

[holytheoristtastemaker]

In this post, we are going to leverage AWS Amplify authentication while still building the UI we want. Prerequisites Seeing as this is a post about AWS and AWS Amplify, you should be set up with both of those. Don't have an AWS account yet? You can set one up here. To interact with AWS Amplify you need to install the CLI via npm. $ yarn global add @aws-amplify/cli Setting up our project Before we can show how to build a custom UI using Amplify, we first need a project to work from. Let's use create-react-app to get a React app going. $ npx create-react-app amplify-demo $ cd amplify-demo With our boilerplate project created we can now add the Amplify libraries we are going to need to it. $ yarn add aws-amplify aws-amplify-react Now we need to initialize Amplify and add authentication to our application. From the root of our new amplify-demo application, run the following commands with the following answers to each question. $ amplify init Note: It is recommended to run this command from the root of your app directory ? Enter a name for the project amplify-demo ? Enter a name for the environment prod ? Choose your default editor: Visual Studio Code ? Choose the type of app that you're building: javascript ? What javascript framework are you using react ? Source Directory Path: src ? Distribution Directory Path: build ? Build Command: npm run-script build ? Start Command: npm run-script start $ amplify add auth Using service: Cognito, provided by: awscloudformation The current configured provider is Amazon Cognito. Do you want to use the default authentication and security configuration? Default configuration Warning: you will not be able to edit these selections. How do you want users to be able to sign in? Username Do you want to configure advanced settings? No, I am done. Successfully added resource amplifydemobc1364f5 locally Now that we have the default authentication via Amplify added to our application we can add the default login. To do that go ahead and update your App component located at src/App.js to have the following code. import React from "react"; import logo from "./logo.svg"; import "./App.css"; import { withAuthenticator } from "aws-amplify-react"; import Amplify from "aws-amplify"; import awsconfig from "./aws-exports"; Amplify.configure(awsconfig); function App() { return ( Internal Application behind Login ); } export default withAuthenticator(App); The default Amplify authentication above leverages the higher-order component, withAuthenticator. We should now be able to see that our App component is behind a login. Go ahead and start the app up in development mode by running yarn start. We should see something like below. Customizing The Amplify Authentication UI Now that we have the default authentication wired up it's time to customize it. In the previous blog post we essentially inherited from the internal Amplify components like SignIn. This allowed us to leverage the functions already defined in that component. But, this felt like the wrong abstraction and a bit of a hack for the long term. It was/is a valid way to get something working. But it required knowing quite a few of the implementation details implemented in the parent component. Things like knowing how handleInputChange and _validAuthStates were getting used in SignIn were critical to making the brute force version below work as expected. import React from "react"; import { SignIn } from "aws-amplify-react"; export class CustomSignIn extends SignIn { constructor(props) { super(props); this._validAuthStates = ["signIn", "signedOut", "signedUp"]; } showComponent(theme) { return ( Username .....omitted..... ); } } But in running with this brute force approach for a bit I was able to form up a better way to customize the Amplify authentication UI. The approach, as we are going to see, boils down to three changes. Instead of using the higher-order component, withAuthenticator. We are going to instead use the component instead. This is the component built into the framework that allows for more customization. We are going to change our App component to make use of an AuthWrapper component that we will write. This is the component that can manage the various states of authentication we can be in. Finally, we will write our own CustomSignIn component to have it's own UI and logic. Let's go ahead and dive in with 1️⃣. Below is what our App component is going to look like now. import React from "react"; import { Authenticator } from "aws-amplify-react"; import "./App.css"; import Amplify from "aws-amplify"; import awsconfig from "./aws-exports"; import AuthWrapper from "./AuthWrapper"; Amplify.configure(awsconfig); function App() { return ( ); } export default App; Notice that our App component is now an entry point into our application. It uses the Authenticator component provided by Amplify instead of the higher-order component. We tell that component to hide all the default authentication UI, we are going to create our own. Then inside of that, we make use of a new component we are going to create called AuthWrapper. This new component is going to act as our router for the different authentication pieces we want to have. For this blog post, we are just going to implement the login workflow. But the idea is transferrable to other things like signing up and forgot password. Here is what AuthWrapper ends up looking like. import React, { Component } from "react"; import { InternalApp } from "./InternalApp"; import { CustomSignIn } from "./SignIn"; class AuthWrapper extends Component { constructor(props) { super(props); this.state = { username: "" }; this.updateUsername = this.updateUsername.bind(this); } updateUsername(newUsername) { this.setState({ username: newUsername }); } render() { return ( ); } } export default AuthWrapper; Here we can see that AuthWrapper is a router for two other components. The first one is CustomSignIn, this is the custom login UI we can build-out. The second one is our InternalApp which is the application UI signed in users can access. Note that both components get the authState passed into them. Internally the components can use this state to determine what they should do. Before taking a look at the CustomSignIn component, let's look at InternalApp to see how authState is leveraged. import React, { Component } from "react"; import logo from "../src/logo.svg"; export class InternalApp extends Component { render() { if (this.props.authState === "signedIn") { return ( Internal Application behind Login ); } else { return null; } } } Notice that we are checking that authState === "signedIn" to determine if we should render the application UI. This is a piece of state that is set by the authentication components defined in AuthWrapper. Now let's see what our customized authentication for the login prompt looks like. Here is what CustomSignIn looks like. import React, { Component } from "react"; import { Auth } from "aws-amplify"; export class CustomSignIn extends Component { constructor(props) { super(props); this._validAuthStates = ["signIn", "signedOut", "signedUp"]; this.signIn = this.signIn.bind(this); this.handleInputChange = this.handleInputChange.bind(this); this.handleFormSubmission = this.handleFormSubmission.bind(this); this.state = {}; } handleFormSubmission(evt) { evt.preventDefault(); this.signIn(); } async signIn() { const username = this.inputs.username; const password = this.inputs.password; try { await Auth.signIn(username, password); this.props.onStateChange("signedIn", {}); } catch (err) { if (err.code === "UserNotConfirmedException") { this.props.updateUsername(username); await Auth.resendSignUp(username); this.props.onStateChange("confirmSignUp", {}); } else if (err.code === "NotAuthorizedException") { // The error happens when the incorrect password is provided this.setState({ error: "Login failed." }); } else if (err.code === "UserNotFoundException") { // The error happens when the supplied username/email does not exist in the Cognito user pool this.setState({ error: "Login failed." }); } else { this.setState({ error: "An error has occurred." }); console.error(err); } } } handleInputChange(evt) { this.inputs = this.inputs || {}; const { name, value, type, checked } = evt.target; const check_type = ["radio", "checkbox"].includes(type); this.inputs[name] = check_type ? checked : value; this.inputs["checkedValue"] = check_type ? value : null; this.setState({ error: "" }); } render() { return ( {this._validAuthStates.includes(this.props.authState) && ( Username Password Login )} ); } } What we have defined up above is a React component that is leveraging the Amplify Authentication API. If we take a look at signIn we see many calls to Auth to sign a user in or resend them a confirmation code. We also see that this._validAuthStates still exists. This internal parameter to determines whether we should show this component inside of the render function. This is a lot cleaner and is not relying on knowing the implementation details of base components provided by Amplify. Making this not only more customizable but a lot less error-prone as well. If you take a look at the class names inside of the markup you'll see that this component is also making use of TailwindCSS. Speaking as a non-designer, Tailwind is a lifesaver. It allows you to build out clean looking interfaces with utility first classes. To add Tailwind into your own React project, complete these steps. Run yarn add tailwindcss --dev in the root of your project. Run ./node_modules/.bin/tailwind init tailwind.js to initialize Tailwind in the root of your project. Create a CSS directory mkdir src/css. Add a tailwind source CSS file at src/css/tailwind.src.css with the following inside of it. @tailwind base; @tailwind components; @tailwind utilities; From there we need to update the scripts in our package.json to build our CSS before anything else. "scripts": { "tailwind:css":"tailwind build src/css/tailwind.src.css -c tailwind.js -o src/css/tailwind.css", "start": "yarn tailwind:css && react-scripts start", "build": "yarn tailwind:css && react-scripts build", "test": "yarn tailwind:css && react-scripts test", "eject": "yarn tailwind:css && react-scripts eject" } Then it is a matter of importing our new Tailwind CSS file, import "./css/tailwind.css"; into the root of our app which is App.js. 💥 We can now make use of Tailwind utility classes inside of our React components. Conclusion AWS Amplify is gaining a lot of traction and it's not hard to see why. They are making it easier and easier to integrate apps into the AWS ecosystem. By abstracting away things like authentication, hosting, etc, folks are able to get apps into AWS at lightning speed. But, with abstractions can come guard rails. Frameworks walk a fine line between providing structure and compressing creativity. They need to provide a solid foundation to build upon. But at the same time, they need to provide avenues for customization. As we saw in this post the default Amplify authentication works fine. But we probably don't want exactly that when it comes to deploying our own applications. With a bit of work and extending the framework into our application, we were able to add that customization.

dotnet 3.0 で WinForms なアプリ動いた。 pic.twitter.com/46TkkM47SP

以下の手順でアプリケーションを作成すると、SayHello というメソッドを持った Greeter サービスが作られる。

$ dotnet new grpc -o mygrpc

proto ファイルは以下の通り。

syntax = "proto3"; option csharp_namespace = "mygrpc"; package Greet; // The greeting service definition. service Greeter {   // Sends a greeting   rpc SayHello (HelloRequest) returns (HelloReply); } // The request message containing the user's name. message HelloRequest {   string name =��1; } // The response message containing the greetings. message HelloReply {   string message = 1; }

dotnet コマンドを使ってそのまま実行できる。

試しにこの proto ファイルから Go のクライアントを作って接続してみる。以下のコマンドで Go のクライアントが作られる。

$ go get github.com/golang/protobuf/protoc-gen-go $ protoc --go_out=plugins=grpc:. greet.proto

以下がそのクライアントを使ったサンプル。dotnet のサーバ側はポート 5000 番で通常ソケットの HTTP、5001 番で HTTP/2 で通信可能。dotnet run コマンドでは HTTP 通信のサーバは起動しないので dotnet build でビルドし、bin 配下にある exe ファイルを実行する。この exe ファイル出力も今回の .NET Core 3.0 の新しい機能になる。

package main import (     "fmt"     "log"     pb "github.com/mattn/grpc-greeter/Greet"     "golang.org/x/net/context"     "google.golang.org/grpc" ) func main() {     conn, err := grpc.Dial("127.0.0.1:5000", grpc.WithInsecure())     if err != nil {         log.Fatal(err)     }     /*         opts = append(opts, grpc.WithTransportCredentials(creds))     */     defer conn.Close()     client := pb.NewGreeterClient(conn)     hello := &pb.HelloRequest{         Name: "おるみん",     }     result, err := client.SayHello(context.Background(), hello)     if err != nil {         log.Fatal(err)     }     fmt.Println(result.GetMessage()) }

実行すると以下の結果が得られる。
