It may contain usage information, categories and other content that is not part of the original module page.

This Lua module is used on approximately 311,000 pages, or roughly 1% of all pages.
To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.

This module depends on the following other modules:

Lua-native alternative to popular flag templates. Can be used to reduce post-expand include size of pages with lots of templates, since it avoids calling multilevel templates.

Caveats

When used inside a template, parameters from that template are passed to the module. This can be useful in some situations, but can lead to conflicts (for example, if the parent template has a parameter |country= that is unrelated to the flag it is supposed to display). To prevent this behavior, add the |frameonly= parameter to the module call, e.g. {{#invoke:flag|deco|CHN|frameonly=true}}.
