Bun 1.2: Built-in S3 and PostgreSQL Support
Bun continues to expand its built-in functionality with native database and cloud storage support.

Native S3 Client

No more aws-sdk for simple S3 operations:

javascript

import { S3Client } from "bun";
const client = new S3Client({


  region: "us-east-1",
});

await client.putObject({ Bucket: "my-bucket", Key: "file.txt", Body: "Hello, World!", });

PostgreSQL Driver

Built-in PostgreSQL support with excellent performance:

javascript

import { sql } from "bun";const users = await sqlSELECT * FROM users;
