Using services in custom medusa routes

Looking to get into development? As a full-stack developer I guide you on this journey and give you bite sized tips every single day 👊

Using services in Medusa routes

For this example, I'll be using the ProductService. First, we'll want to add a custom route endpoint.

Inside our custom route, we can start by assigning this service like this.

const productService = req.scope.resolve('productService');

Let's say we want to list all products. We can easily do that with the following command.

router.get('/store/test', async (req, res) => { const productService = req.scope.resolve('productService'); productService.list().then((products) => { res.json(products); }); });

If you now restart your server and query this endpoint, you should be able to see a list of your products. (My database only has one effect).

This is, of course, not super beneficial as we already have an endpoint to retrieve precisely this information. The cool part is that we can choose to manipulate this data. Let's say we only want items that have stock.

router.get('/store/test', async (req, res) => { const productService = req.scope.resolve('productService'); productService.list({}, { relations: ['variants'] }).then((products) => { res.json( products.filter((product) => product.variants.some((variant) => variant.inventory_quantity >= 0) ) ); }); });

We have quite a few changes here. Let's take a closer look. The first one is that we pass arguments to the products list function. These arguments are as follows:

{}: The first option is the params to query on. In our case, nothing in particular

{relations:['variants']}: This can be used to add specific options to the query. We want to add the variants

Once we have this, we filter all products and only return products where at least one variant has stock.

You can play with adjusting the stock levels in the query.

And that's it, we super powerful way of querying from service in medusa.
