What is a database connection string?

A connection string is one URL holding everything a client needs to reach a database: username, password, host, port, database name and options such as sslmode.

The short version

A connection string is one URL holding everything a client needs to reach a database: username, password, host, port, database name and options such as sslmode. Treat it as a secret, and keep it in an environment variable rather than in your code. Rotating the password changes the string, so every app using it needs the new value.
