RDS Connection String Generator

How to use

About this tool

Enter connection information for AWS RDS instances and generate connection strings in multiple formats (DSN, URL, Laravel .env, JDBC, Python, Node.js). Supports database engines (MySQL, PostgreSQL, MariaDB, Oracle, SQL Server, Aurora) with options for SSL settings, timezone, charset, read replicas, and connection pool settings.

How to use

1. Enter basic information: Select database engine and enter hostname, port, username, password, and database name. When you change the engine, the default port is automatically set. 2. Optional settings: Specify timezone, charset, and SSL settings. 3. Advanced settings: Configure read replicas, connection pools, IAM authentication, and Secrets Manager integration. 4. View connection strings: Connection strings are generated in real time as you type. Switch between formats using tabs and copy the format you need.

Options

Use cases

• Laravel project setup (generating .env file and config/database.php settings) • Multi-environment connection management (switching between dev/staging/prod with presets) • Sharing across multiple language projects (generating connection strings for PHP, Node.js, Python, Java simultaneously) • SSL certificate configuration verification (generating connection strings with appropriate SSL parameters) • Read replica utilization (generating read/write separation settings) • Connection pool optimization (generating connection strings with pool settings)

Code Examples

1$dsn = "mysql:host=example.rds.amazonaws.com;port=3306;dbname=mydb;charset=utf8mb4";
2$pdo = new PDO($dsn, $username, $password);

1const mysql = require('mysql2');
2const connection = mysql.createConnection({
3  host: 'example.rds.amazonaws.com',
4  port: 3306,
5  user: 'admin',
6  password: 'password',
7  database: 'mydb'
8});

1from sqlalchemy import create_engine
2engine = create_engine(
3  "mysql+pymysql://user:[email protected]:3306/mydb"
4)

1String url = "jdbc:mysql://example.rds.amazonaws.com:3306/mydb";
2Connection conn = DriverManager.getConnection(url, username, password);

How it works

Connection string generation builds strings according to standard specifications for each format based on the input connection information (engine, host, port, credentials, options). DSN format follows PHP PDO standard, URL format follows RFC 3986, Laravel format follows Laravel standard, JDBC format follows Java Database Connectivity standard, Python format follows SQLAlchemy standard, and Node.js format follows each driver's configuration object format. Special characters in passwords are properly escaped in URL format. All processing is done in the browser; connection information is never sent to any server.

Privacy and data

All processing is done in the browser; connection information (hostname, username, password, database name, etc.) is never sent to any server. When using the preset feature, settings are saved in the browser's local storage but are not sent to any server.

FAQ

Q: Does this tool support Aurora?

A: Yes. Aurora MySQL and Aurora PostgreSQL are both supported. You can select them from the database engine dropdown.

Q: Is my password sent to any server?

A: No. All processing is done entirely in your browser. Connection information (hostname, username, password, database name, etc.) is never sent to any server.

Q: What connection string formats are supported?

A: DSN, URL, Laravel .env, JDBC, Python (SQLAlchemy), and Node.js formats are supported. You can switch between them using the format tabs.

Q: Can I use this for local MySQL, not just AWS RDS?

A: Yes. While designed for RDS, the generated strings work with any MySQL, PostgreSQL, or MariaDB instance (local or cloud).
