使用typescript播种mongoose (MongoDB)数据库

mkdir myproject
cd myproject
npm init

npm install typescript mongoose

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "outDir": "dist",
    "strict": true,
    "esModuleInterop": true
  },
  "include": [
    "src/**/*.ts"
  ],
  "exclude": [
    "node_modules"
  ]
}

import mongoose from 'mongoose';

// 连接 MongoDB 数据库
mongoose.connect('mongodb://localhost/mydatabase', {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});

// 定义模型
const UserSchema = new mongoose.Schema({
  name: String,
  age: Number,
});

const UserModel = mongoose.model('User', UserSchema);

// 使用模型进行数据库操作
async function main() {
  const user = new UserModel({
    name: 'John Doe',
    age: 25,
  });

  await user.save();

  const users = await UserModel.find();
  console.log(users);
}

main().catch(console.error);
