Adding slug to req params url in express - node.js

Question

I'm using the 'slug' npm library to give-strings-dashes-for-url-cleanliness. The library works when I console.log() a string, and it's required properly into all of the relevant controllers.
However, I can't figure out how implement slug() properly to format my URLs. The problem I'm having is that a product name might be "Foo Bar Baz Quux", but I can't seem to find the right implementation for slug() without disrupting the connection between the app.js route and the findOne query via mongoose.
app.js
app.get('/market/:product_name', marketController.getProduct);
controller.js
exports.getProduct = function(req, res, next) {
var product_name = req.params.product_name;
// var slugProduct = slug(product_name);
Product.findOne({'name': product_name}, function(err, product) {
if (err) return next(err);
return res.send(product.data);
});
}

Perhaps you could "slugify" a product by defining a slug property while setting up your "Product Schema". I can confirm it works if using mongoose with along mongoose-slug-generator plugin, see link... You could set it up as follows:
const mongoose = require('mongoose');
const { Schema } = mongoose;
const slug = require('mongoose-slug-generator');
// * mongoose slug generator options
const options = {
separator: '-',
lang: 'en',
truncate: 120
};
// * Init mongoose slug generator plugin
mongoose.plugin(slug, options);
const ProductSchema = new Schema({
name: {
type: String,
trim: true
},
slug: {
type: String,
slug: 'name', // genarating slug from multiple properties is allowed ['name', 'brand']
unique: true
},
price: {
type: Number,
required: true
},
brand: {
type: String,
default: 'Apple'
}
});
module.exports = mongoose.model('Product', ProductSchema);
exports.getProduct = function(req, res, next) {
const { product_name } = req.params;
Product.findOne({ slug: product_name }, function(err, product) {
if (err) return next(err);
if (!product) {
return res.status(404).json({
message: 'Product data not found.'
);
}
res.status(200).send(product);
});
}
app.get('/market/:product_name', marketController.getProduct)
// request
const response = await axios.get('/api/market/my-awesome-product')
// response.data
{
"_id": "60fh4d37ac1a1c6f58d6a5f4",
"name": "My Awesome Product",
"slug": "my-awesome-product",
"price": 85.9,
"brand": "Apple"
}
