一、什么是全栈开发
A full-stack web application is a complete software application that encompasses both the frontend and backend components. It’s designed to interact with users through a web browser and perform actions that involve data processing and storage.
全栈 Web 应用程序是一个完整的软件应用程序,包括前端和后端组件。它旨在通过 Web 浏览器与用户交互,并执行涉及数据处理和存储。
1.1 前端
The frontend of a web application is the part that users directly interact with. It’s responsible for the visual elements, user interface, and user experience. Technologies like HTML, CSS, and JavaScript are commonly used to build the frontend. In the context of modern web development, frameworks like React have become increasingly popular due to their component-based architecture and efficiency.
Web 应用程序的前端是用户直接与之交互的部分。它负责视觉元素、用户界面和用户体验。HTML、CSS 和 JavaScript 等技术通常用于构建前端。在现代 Web 开发的背景下,像 React 这样的框架由于其基于组件的架构和效率而变得越来越流行。
1.2 后端
The backend of a web application handles the business logic, data management, and server-side operations. It interacts with databases, performs calculations, and manages user authentication. Languages like Python, Ruby, and Node.js are often used for backend development. FastAPI, a Python-based framework, is gaining traction for its speed and ease of use.
Web 应用程序的后端处理业务逻辑、数据管理和服务器端作。它与数据库交互、执行计算并管理用户身份验证。Python、Ruby 和 Node.js 等语言通常用于后端开发。FastAPI 是一个基于 Python 的框架,因其速度和易用性而越来越受欢迎。
1.3 数据库
A database is crucial for storing and managing application data. Relational databases like MySQL and PostgreSQL have been traditionally popular, but NoSQL databases like MongoDB have gained significant ground due to their flexibility and scalability.
