TypeScript实战项目：内容管理系统（CMS）开发指南
内容管理系统（Content Management System，简称CMS）是一种用于创建、编辑、发布和管理网站内容的软件。在当今数字化时代，CMS已经成为企业、组织和个人管理网站内容的重要工具。TypeScript作为一种JavaScript的超集，提供了类型系统、模块化和编译时类型检查等特性，使得开发大型、复杂的应用程序变得更加容易。本文将围绕TypeScript语言，实战开发一个内容管理系统（CMS）。
项目概述
本篇文章将介绍如何使用TypeScript开发一个简单的CMS。我们将实现以下功能：
1. 用户注册与登录
2. 文章管理
3. 分类管理
4. 文章发布与预览
5. 文章搜索
技术栈
- TypeScript
- Node.js
- Express
- MongoDB
- Mongoose
- Bootstrap
- Axios
开发环境搭建
1. 安装Node.js和npm（Node Package Manager）
2. 创建一个新的TypeScript项目
bash
mkdir my-cms
cd my-cms
npm init -y
npm install typescript --save-dev
npx tsc --init
3. 安装项目依赖
bash
npm install express mongoose body-parser cors --save
npm install @types/node @types/express @types/mongoose @types/body-parser @types/cors --save-dev
4. 配置tsconfig.json
json
{
"compilerOptions": {
"target": "es6",
"module": "commonjs",
"strict": true,
"esModuleInterop": true
}
}
5. 创建项目结构
my-cms/
├── src/
│ ├── models/
│ │ └── article.ts
│ ├── routes/
│ │ └── articleRoutes.ts
│ ├── controllers/
│ │ └── articleController.ts
│ ├── app.ts
│ └── server.ts
├── public/
│ └── index.html
├── package.json
└── tsconfig.json
用户注册与登录
1. 创建用户模型
在`src/models/article.ts`中定义用户模型：
typescript
import mongoose, { Document, Schema } from 'mongoose';
interface IUser extends Document {
username: string;
password: string;
}
const userSchema: Schema = new Schema({
username: { type: String, required: true },
password: { type: String, required: true }
});
export default mongoose.model('User', userSchema);
2. 创建用户控制器
在`src/controllers/articleController.ts`中创建用户控制器：
typescript
import { Request, Response } from 'express';
import User from '../models/article';
export const register = async (req: Request, res: Response) => {
const { username, password } = req.body;
try {
const user = new User({ username, password });
await user.save();
res.status(201).send('User registered successfully');
} catch (error) {
res.status(500).send('Error registering new user');
}
};
export const login = async (req: Request, res: Response) => {
const { username, password } = req.body;
try {
const user = await User.findOne({ username, password });
if (!user) {
return res.status(401).send('Invalid credentials');
}
res.status(200).send('Login successful');
} catch (error) {
res.status(500).send('Error logging in');
}
};
3. 创建用户路由
在`src/routes/articleRoutes.ts`中创建用户路由：
typescript
import { Router } from 'express';
import articleController from '../controllers/articleController';
const router: Router = Router();
router.post('/register', articleController.register);
router.post('/login', articleController.login);
export default router;
4. 配置Express应用
在`src/app.ts`中配置Express应用：
typescript
import express from 'express';
import articleRoutes from './routes/articleRoutes';
const app: express.Application = express();
app.use(express.json());
app.use('/api', articleRoutes);
export default app;
5. 启动服务器
在`src/server.ts`中启动服务器：
typescript
import app from './app';
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});

category: mongoose.Types.ObjectId;
publishedAt: Date;
}
const articleSchema: Schema = new Schema({
title: { type: String, required: true },
content: { type: String, required: true },
author: { type: mongoose.Schema.Types.ObjectId, ref: 'User', required: true },
category: { type: mongoose.Schema.Types.ObjectId, ref: 'Category', required: true },
publishedAt: { type: Date, default: Date.now }
});
export default mongoose.model('Article', articleSchema);

export const createArticle = async (req: Request, res: Response) => {
const { title, content, author, category } = req.body;
try {
const article = new Article({ title, content, author, category });
await article.save();
res.status(201).send('Article created successfully');
} catch (error) {
res.status(500).send('Error creating article');
}
};
export const getArticles = async (req: Request, res: Response) => {
try {
const articles = await Article.find();
res.status(200).send(articles);
} catch (error) {
res.status(500).send('Error fetching articles');
}
};
3. 创建文章路由
