mongodb - unique field allover documents of collection

I am new to MongoDB and I want to add validation of a unique field (product slug) among all the documents of the collection.

If the user adds a new product and slug of that new product already available in MongoDB then it should give me an error. I have experience in MySQL. If I make that field unique it will give me an error. So, How could I implement such kind of functionality using MongoDB validator?

Can anyone help me with this?

You can set a unique index on the field.

Something like

db.products.createIndex({"slug": 1}, { "unique": true})
