Implement task #168 - Start new web application project

[brian-ai-assistant[bot]]

Architecture

For this web application project, I have chosen to use Nuxt.js as the frontend framework and Firebase Functions for the backend. Nuxt.js is a powerful framework for building Vue.js applications, and it provides server-side rendering capabilities along with a rich ecosystem of plugins and modules. Firebase Functions is a serverless framework provided by Google, which allows us to write and deploy Node.js functions

Firebase Authentication will be used for user authentication, and TypeScript will be used as the programming language for both the frontend and backend codebases.

The project structure will be as follows:

• frontend folder: This folder will contain the Nuxt.js application code, including the views, components, and Vuex store.
• backend folder: This folder will contain the Firebase Functions code, including the Express.js routes and the server-side logic.

Security Measures

To ensure the security of the web application, we will implement the following measures:

1. Authentication and Authorization: We will use Firebase Authentication to handle user authentication. This will allow us to authenticate users and manage their access and permissions to different parts of the application.
2. HTTPS: We will enforce HTTPS for all communication between the client and server to ensure the confidentiality and integrity of the data transmitted.
3. Input Validation: We will implement proper input validation and sanitization techniques to prevent common security vulnerabilities such as SQL injection, XSS attacks, etc.
4. Secure Data Storage: Any sensitive data, such as user credentials or personal information, will be securely stored using encryption and best practices recommended by Firebase.
5. Secure Communication: All communications between the client and server will be protected using secure protocols, such as HTTPS and SSL/TLS.
6. Access Controls: We will implement appropriate access controls and permission checks to ensure that users can only access the data and functionality they are authorized to.
7. Error Handling: Proper error handling and log mechanism will be implemented to handle exceptions and prevent information disclosure.
8. JWT Tokens: We will use JSON Web Tokens (JWT) for managing and verifying user authentication and authorization.

// Sample code snippets for implementing JWT authentication

// User login
const login = (req, res) => {
  const { email, password } = req.body;
  // Validate user credentials
  // Generate JWT token
  // Return token to client
}

// Protect route
const protectedRoute = (req, res) => {
  // Verify JWT token
  // Access protected resource
  // Return response
}

Code

I have created the following files with their respective contents for the project setup:

• README.md: Contains project information and documentation.
• img/: Empty folder to store images.
• main.ts: Entry point file for the backend codebase.
• package.json: Contains project dependencies and scripts.
• src/app.module.ts: Nest.js app module file.
• tsconfig.build.json: TypeScript configuration file for building the backend code.
• tsconfig.json: TypeScript configuration file.
• utils/logger.ts: Logger utility class for handling logging in the backend.
