no-empty-footer-link-columns

Disallow footer link columns whose items arrays are statically empty.

Targeted pattern scope

This rule targets docusaurus.config.* files and inspects themeConfig.footer.links column objects.

What this rule reports

This rule reports footer columns whose items arrays resolve statically to [].

Why this rule exists

Empty footer columns take up space, add visual noise, and often indicate unfinished or copy/pasted configuration.

❌ Incorrect

export default {
    themeConfig: {
        footer: {
            links: [{ title: "Docs", items: [] }],
        },
    },
};

✅ Correct

export default {
    themeConfig: {
        footer: {
            links: [
                {
                    title: "Docs",
                    items: [{ label: "Overview", to: "/docs" }],
                },
            ],
        },
    },
};

Behavior and migration notes

This rule autofixes by removing empty footer columns from static themeConfig.footer.links arrays.

When not to use it

Do not use this rule if your footer intentionally includes placeholder columns for later runtime population.
