How it works

Driver, host, port, database, user, password, TLS, and extra options are serialized into the selected key-value or URI syntax. Values containing separators are quoted or percent-encoded for that format.

  • Driver defaults are starting hints, not server guarantees.
  • Driver-specific options remain explicit.

Worked example

PostgreSQL Connection URI
Build a PostgreSQL connection URI with credentials and SSL
Input
											Driver: postgresql
Host: db.example.com
Port: 5432
Database: myapp
Username: admin
Password: secret
SSL: true
Output
												postgresql://admin:[email protected]/myapp?sslmode=require

When to use this

Application secrets, migration tools, and local database READMEs build connection strings.

Edge cases

  • @ or # in URI passwords must be encoded.
  • IPv6 hosts need brackets in a URI authority.
  • TLS options differ between drivers.
