no-empty-config-link-labels

Disallow empty label values on Docusaurus theme-config link items.

Targeted pattern scope

This rule targets docusaurus.config.* files and inspects default Docusaurus theme-config link items in navbar and footer arrays.

What this rule reports

This rule reports label properties whose static string value is empty or whitespace-only.

Why this rule exists

Empty link labels usually come from copy/paste or unfinished configuration and make navigation harder to understand.

❌ Incorrect

export default {
    themeConfig: {
        navbar: {
            items: [{ label: "", to: "/docs/intro" }],
        },
    },
};

✅ Correct

export default {
    themeConfig: {
        navbar: {
            items: [{ label: "Docs", to: "/docs/intro" }],
        },
    },
};

Behavior and migration notes

When html already provides visible content, this rule autofixes by removing the empty label property.

When not to use it

Do not use this rule if empty labels are intentionally used as placeholders for a later transform step.
