Desktop Deployment

pgAdmin may be deployed as a desktop application by configuring the application to run in desktop mode and then utilising the desktop runtime to host the program on a supported Windows, Mac OS X or Linux installation.

The desktop runtime is a standalone application that when launched, runs the pgAdmin server and opens a window to render the user interface.

Note

Pre-compiled and configured installation packages are available for a number of platforms. These packages should be used by end-users whereever possible - the following information is useful for the maintainers of those packages and users interested in understanding how pgAdmin works.

See also

For detailed instructions on building and configuring pgAdmin from scratch, please see the README file in the top level directory of the source code. For convenience, you can find the latest version of the file here, but be aware that this may differ from the version included with the source code for a specific version of pgAdmin.

Configuration

From pgAdmin 4 v2 onwards, the default configuration mode is server, however, this is overridden by the desktop runtime at startup. In most environments, no Python configuration is required unless you wish to override other default settings.

See The config.py File for more information on configuration settings.

Desktop Runtime Standalone Application

The Desktop Runtime is based on NWjs which integrates a browser and the Python server creating a standalone application.

Runtime Menu

Use the File Menu to access the Runtime Menu:

Option

Action

Configure…

Click to open configuration dialog to configure fixed port, port number and connection timeout.

View log…

Click to open the view log dialog to view the pgAdmin 4 logs.

Enter Full Screen

Click to enter/exit the full screen mode. Keyboard Shortcuts: OSX (Cmd + Ctrl + F), Other OS (F10).

Configuration Dialog

Use the Runtime Menu to access the Configuration dialog:

Runtime Configuration

Following are the details of the Fixed port number?, Port Number, and Connection Timeout configuration parameters:

Key

Type

Purpose

FixedPort

Boolean

Use a fixed network port number rather than a random one.

PortNumber

Integer

The port number to use, if using a fixed port.

ConnectionTimeout

Integer

The number of seconds to wait for application server startup.

Log dialog

Use the Runtime Menu to access the Log dialog:

Runtime View Log

Click on the Reload button at the bottom to view the latest logs of pgAdmin 4 Server.

When executed, the runtime will automatically try to execute the pgAdmin Python application. If execution fails, it will prompt you with error message displaying a Configure button at the bottom. You can configure a fixed port number to avoid clashes of the default random port number with other applications and a connection timeout if desired.

Runtime Error

If the error is related to Python Path or pgAdmin Python file then you need to create a file named ‘dev_config.json’ and specify the following entries:

{
    "pythonPath": "/path/to/python.exe",
    "pgadminFile": "/path/to/pgAdmin4.py"
}

Note that the dev_config.py file should only be required by developers who are working outside of a standard installation.

The configuration settings are stored in runtime_config.json file, which will be available on Unix systems (~/.local/share/pgadmin/), on Mac OS X (~/Library/Preferences/pgadmin), and on Windows (%APPDATA%/pgadmin).
