===Modules===
{{main|Wikipedia:Lua}}
Lua modules are sometimes used instead of templates to store reusable material. Reasons for this include usage of module-specific features such as [[loop (programming)|loops]] or stored values, and complex code is often easier to read and maintain in a module. If a module is easily implementable in a template it generally should be, since there are more users with experience editing templates.

If a module is intended to be used in articles or talk pages, a template wrapper should generally be created to simplify usage without directly requiring the <code>#invoke</code> parser function. Documentation is then mostly located on the template's /doc page, with the module's documentation pointing to the template and/or explaining further technical details that are unnecessary at the primary template documentation.

A template wrapper uses more of the [[WP:PEIS|post-expand include size limit]] than calling the module directly, therefore it may be necessary to avoid using one in articles that are near the limit.
