`Desktop Deployment`:index:
|
|
***************************
|
|
|
|
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.
|
|
|
|
.. seealso:: 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 <https://git.postgresql.org/gitweb/?p=pgadmin4.git;a=blob;f=README.md>`_,
|
|
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 :ref:`config_py` for more information on configuration settings.
|
|
|
|
Desktop Runtime Standalone Application
|
|
======================================
|
|
|
|
The Desktop Runtime is based on `NWjs <https://nwjs.io/>`_ which integrates a
|
|
browser and the Python server creating a standalone application.

Log dialog
|
|
----------
|
|
|
|
Use the *Runtime Menu* to access the *Log* dialog:
|
|
|
|
.. image:: images/runtime_view_log.png
|
|
:alt: Runtime View Log
|
|
:align: center
|
|
|
|
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.
|
|
|
|
.. image:: images/runtime_error.png
|
|
:alt: Runtime Error
|
|
:align: center
|
|
|
|
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:
|
|
|
|
.. code-block:: json
|
|
|
|
{
|
|
"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).
