How do i get an array instead of an object using mongoose?

Question

i use Mongoose to get my data from my database with this get function.

router.get("/:id", async (req, res)=> {
  const products = await Product.findOne({slug: req.params.id});
  if (products) {
    res.send(products);
  } else {
    res.status(404).send({message:"product not found"})
  } 
});

The output seems to be an object. However i need a array instead, because i use the slice() method in my further code.

What i tried: var ready = Object.keys(products).map((key) => [Number(key), products[key]]);

Is there any function i could use to make an array instead of the object or another mongoose function for getting an array?

The easier approach would be to use find as it always returns an array. In your case:

const products = await Product.findslug: req.params.id});

Also note that if (products) { would now always return true, so you may want to update to if (products.length) { (in case you need at least 1 document).

There's also aggregate method available that also returns an array but usually it's being used for a little more advanced queries. If your query is as simple as you have provided, you don't need aggregate here.
