使用 Mongoose 和 Bun 读写 MongoDB 数据

mkdir mongoose-app
cd mongoose-app
bun init

bun add mongoose

import * as mongoose from "mongoose";

const animalSchema = new mongoose.Schema(
  {
    name: { type: String, required: true },
    sound: { type: String, required: true },
  },
  {
    methods: {
      speak() {
        console.log(`${this.sound}!`);
      },
    },
  },
);

export type Animal = mongoose.InferSchemaType<typeof animalSchema>;
export const Animal = mongoose.model("Animal", animalSchema);

import * as mongoose from "mongoose";
import { Animal } from "./schema";

// 连接数据库
await mongoose.connect("mongodb://127.0.0.1:27017/mongoose-app");

// 创建新的 Animal 实例
const cow = new Animal({
  name: "Cow",
  sound: "Moo",
});
await cow.save(); // 保存到数据库

// 读取所有 Animals
const animals = await Animal.find();
animals[0]!.speak(); // logs "Moo!"

// 断开连接
await mongoose.disconnect();

bun run index.ts
