Detailed Description and Functionality of Tech Stack Tools
Next.js
Next.js is a powerful React framework that enables server-side rendering (SSR) and static site generation (SSG), enhancing performance and SEO. In NkBanks, it is used to build the frontend application, providing seamless navigation, optimized page loading, and robust performance. It simplifies routing and supports API routes for backend integration.
How It Works:
- Server-side Rendering (SSR): Fetches data and renders pages dynamically on the server.
- Static Site Generation (SSG): Generates static HTML pages at build time.
- File-based Routing: Creates routes automatically based on the file structure.
TypeScript
TypeScript is a superset of JavaScript that introduces static typing, making code more robust and easier to debug. In NkBanks, it ensures type safety and prevents runtime errors.
How It Works:
- Static Typing: Detects type-related errors during development.
- Code Predictability: Improves developer experience with better autocomplete and IntelliSense.
- Integration with Next.js: Ensures compatibility and enhances the reliability of components.
Appwrite
Appwrite is an open-source backend-as-a-service (BaaS) platform providing database, authentication, and storage services. In NkBanks, it handles user authentication, secure data management, and cloud functions.
How It Works:
- Authentication: Manages user login, registration, and session handling.
- Database: Provides a NoSQL database for storing user data.
- Cloud Functions: Executes custom backend logic.
Plaid
Plaid is a financial technology API that connects bank accounts to applications. In NkBanks, it allows users to link their accounts securely and fetch transaction data in real time.
How It Works:
