✅ 1. Fetch Custom Post Type (product)

Just replace 'post' with 'product':

const { products, isLoading } = useSelect((select) => {
	const query = {
		per_page: 5,
		_fields: ['id', 'title'],
	};	return {
		products: select('core').getEntityRecords('postType', 'product', query),
		isLoading: !select('core').hasFinishedResolution(
			'getEntityRecords',
			['postType', 'product', query]
		),
	};
}, []);

---

✅ 2. Fetch Taxonomy (product_cat)

For taxonomies, entity type changes from 'postType' → 'taxonomy'

const { categories, isCatLoading } = useSelect((select) => {
	const query = {
		per_page: 10,
		_fields: ['id', 'name'],
	};	return {
		categories: select('core').getEntityRecords('taxonomy', 'product_cat', query),
		isCatLoading: !select('core').hasFinishedResolution(
			'getEntityRecords',
			['taxonomy', 'product_cat', query]
		),
	};
}, []);

---

🚀 3. Fetch BOTH (Best Practice – Single useSelect)

👉 This is what you should do in production (avoids multiple subscriptions)

const { products, categories, isLoading } = useSelect((select) => {
	const productQuery = {
		per_page: 5,
		_fields: ['id', 'title'],
	};	const categoryQuery = {
		per_page: 10,
		_fields: ['id', 'name'],
	};	const core = select('core');	return {
		products: core.getEntityRecords('postType', 'product', productQuery),
		categories: core.getEntityRecords('taxonomy', 'product_cat', categoryQuery),		isLoading:
			!core.hasFinishedResolution('getEntityRecords', ['postType', 'product', productQuery]) ||
			!core.hasFinishedResolution('getEntityRecords', ['taxonomy', 'product_cat', categoryQuery]),
	};
}, []);

🔗 4. Filter Products by Category (Very Useful)

If you want products by category, pass taxonomy query:

const query = {
	per_page: 5,
	product_cat: 12, // category ID
};

👉 Full example:

products: core.getEntityRecords('postType', 'product', {
	per_page: 5,
	product_cat: 12,
})

⚠️ Important Notes

1. CPT must be exposed to REST API

When registering CPT:

'show_in_rest' => true,

---

2. Taxonomy must also support REST

'show_in_rest' => true,

---

3. _fields optimization

Be careful:

_fields: ['id', 'title']

• Works for posts
• For taxonomy → use name, not title

---

🧠 Key Takeaways

• CPT → 'postType', 'product'
• Taxonomy → 'taxonomy', 'product_cat'
• Combine in single useSelect for performance
• Use hasFinishedResolution for loading state
• Pass taxonomy slug in query to filter posts
