📝 Require a last default entry in exports/imports conditions objects.

💼 This rule is enabled in the ✅ recommended config.

Conditions are resolved top to bottom. This rule requires each conditions object in exports and imports to end with a default fallback.

Note

Some packages deliberately omit default so that resolution fails for unsupported platforms. Disable the rule for those cases.

Examples

// ❌
{
	"exports": {
		"types": "./index.d.ts",
		"import": "./index.js"
	}
}

// ❌
{
	"exports": {
		"default": "./index.cjs",
		"import": "./index.mjs"
	}
}

// ✅
{
	"exports": {
		"types": "./index.d.ts",
		"import": "./index.js",
		"default": "./index.cjs"
	}
