MySQL Router 8.0 Release Notes
A script to define and register extension objects must have a file
extension of .js for JavaScript code, or
.py for Python code, to match the language used
for the script. The file extension is not case-sensitive.
The preferred way to persist an extension object is by adding it
into a MySQL Shell plugin. Plugins and plugin groups are loaded
automatically when MySQL Shell starts, and the functions that
they define and register are available immediately. In a
MySQL Shell plugin, the file containing the initialization script
must be named init.js or
init.py as appropriate for the language. A
plugin can only contain code in one language, so if you are
creating an extension object with a mix of members defined in
Python and members defined in JavaScript, you must store the
members as separate language-appropriate plugins. For instructions
to use MySQL Shell plugins, see
Section 10.3, “MySQL Shell Plugins”.
As an alternative, scripts containing extension objects can be
stored directly in the init.d folder in the
MySQL Shell user configuration path. When MySQL Shell starts,
all files found in the init.d folder with a
.js or .py file
extension are processed automatically and the functions that they
register are made available. (In this location, the file name does
not matter to MySQL Shell.) The default MySQL Shell user
configuration path is ~/.mysqlsh/ on Unix and
%AppData%\MySQL\mysqlsh\ on Windows. The user
configuration path can be overridden on all platforms by defining
the environment variable
MYSQLSH_USER_CONFIG_HOME.
