MongoDB and Mongoose work with Bun with no extra configuration. This guide assumes you've already installed MongoDB and are running it as a background process or service on your development machine. See the [MongoDB installation guide](https://www.mongodb.com/docs/manual/installation/) for details.
|
|

|
|
|
|
Once MongoDB is running, create a directory and initialize it with `bun init`.
|
|
|
|
```sh terminal icon="terminal"
|
|
mkdir mongoose-app
|
|
cd mongoose-app
|
|
bun init
|
|
```
|
|
|
|
---
|
|
|
|
Then add Mongoose as a dependency.
|
|
|
|
```sh terminal icon="terminal"
|
|
bun add mongoose
|
|
```
|
|
|
|
---
|
|
|
|
In `schema.ts`, declare and export an `Animal` model.
|
|
|
|
```ts schema.ts icon="/icons/typescript.svg"
|
|
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);
|
|
```
|
|
|
|
---
|
|
|
|
In `index.ts`, import `Animal`, connect to MongoDB, and add some data to the database.
|
|
|
|
```ts index.ts icon="/icons/typescript.svg"
|
|
import * as mongoose from "mongoose";
|
|
import { Animal } from "./schema";
|
|
|
|
// connect to database
|
|
await mongoose.connect("mongodb://127.0.0.1:27017/mongoose-app");
|
|
|
|
// create new Animal
|
|
const cow = new Animal({
|
|
name: "Cow",
|
|
sound: "Moo",
|
|
});
|
|
await cow.save(); // saves to the database
|
|
|
|
// read all Animals
|
|
const animals = await Animal.find();
|
|
animals[0]!.speak(); // logs "Moo!"
|
|
|
|
// disconnect
|
|
await mongoose.disconnect();
|
|
```
|
|
|
|
---
|
|
|
|
Run the file with `bun run`.
|
|
|
|
```bash terminal icon="terminal"
|
|
bun run index.ts
|
|
```
|
|
|
|
```txt
|
|
Moo!
|
|
```
