Neon CLI command: connection-string

The connection-string command gets a Postgres connection string for any database on any branch in your Neon project. The connection string includes the password for the specified role. For information about connecting to Neon, see Connect from any application. If --project-id is omitted, the CLI resolves it from your context file, auto-selects when your account has only one project, and prompts otherwise. --role-name and --database-name are needed only when the branch has more than one role or database.

Usage

neon connection-string [branch] [options]

The [branch] is the branch name or ID. If omitted, the default branch is used. To connect to a specific point in the branch's history, use the point-in-time format branch@timestamp or branch@lsn. If no timestamp or LSN is appended, the current state (HEAD) is used.

Options

The --endpoint-type value can be read_write (the default) or read_only. The --psql option doesn't require a psql installation: if psql isn't on your $PATH, the CLI uses a built-in TypeScript implementation. To save your project context to a file and avoid repeating --project-id, see Using a named context file.

Examples

Get a connection string for a branch:

neon connection-string mybranch

postgresql://alex:AbC123dEf@ep-cool-darkness-123456.us-east-2.aws.neon.tech/dbname?sslmode=require&channel_binding=require

• Get a pooled connection string. The --pooled option adds a -pooler suffix to the host name, which enables connection pooling for clients that use this connection string.

  neon connection-string --pooled

  postgresql://alex:AbC123dEf@ep-cool-darkness-123456-pooler.us-east-2.aws.neon.tech/dbname?sslmode=require&channel_binding=require

• Get a connection string for use with Prisma. The --prisma option adds connect_timeout=30 to the connection string so that connections from Prisma Client don't time out.

  neon connection-string --prisma

  postgresql://alex:AbC123dEf@ep-cool-darkness-123456.us-east-2.aws.neon.tech/dbname?sslmode=require&channel_binding=require&connect_timeout=30

• Get a connection string to a specific point in a branch's history by appending @timestamp or @lsn. Availability depends on your configured history window. For additional examples, see How to use Time Travel.
