Neon CLI commands — connection-string

Before you begin

Before running the connection-string command, ensure that you have installed the Neon CLI.
If you have not authenticated with the neon auth command, running a Neon CLI command automatically launches the Neon CLI browser authentication process. Alternatively, you can specify a Neon API key using the --api-key option when running a command. See Connect.

For information about connecting to Neon, see Connect from any application.

The `connection-string` command

This command gets a Postgres connection string for connecting to a database in your Neon project. You can construct a connection string for any database in any branch. The connection string includes the password for the specified role.

Usage

neon connection-string [branch[@timestamp|@LSN]] [options]

branch specifies the branch name or ID. If a branch name or ID is omitted, the default branch is used. @timestamp|@LSN is used to specify a specific point in the branch's history for time travel connections. If omitted, the current state (HEAD) is used.

In addition to the Neon CLI global options, the connection-string command supports these options:

Option	Description	Type	Required
`--context-file`	Context file path and file name	string
`--project-id`	Project ID	string	Only if your Neon account has more than one project

Examples

Get a basic connection string for the current project, branch, and database:

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 for the current project, branch, and database with the --pooled option. This option adds a -pooler flag 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 for the current project, branch, and database. The --prisma options adds connect_timeout=30 option to the connection string to ensure that connections from Prisma Client do not timeout.
```
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 restore window window.
```
neon connection-string @2024-04-21T00:00:00Z
```
For additional examples, see How to use Time Travel.
Get a connection string and connect with psql.
```
neon connection-string --psql
```
Get a connection string, connect with psql, and run an .sql file.
