Why does mongoose always add an s to the end of my collection name

Why is Mongoose Adding an "s" to the End of My Collection Name? 😱

So, you've been using Mongoose, the popular MongoDB object modeling library, and you've noticed something peculiar: every time you create a model, Mongoose automatically adds an "s" to the end of your collection name. Why is this happening? Don't worry, you're not alone in wondering!

The Mysterious "s" Addition 🕵️‍♂️

Let's take a closer look at the code examples you provided:

var Dataset = mongoose.model('data', dataSchema);
var User = mongoose.model('user', dataSchema);

In both cases, Mongoose is creating a model with the given name (e.g., "data" or "user"), but the collection name ends up being "datas" and "users," respectively. What's the deal with that extra "s"? 🤔

Understanding Pluralization Rules 📚

To understand why Mongoose adds an "s" to your collection name, we need to delve into the world of English language pluralization rules. In English grammar, most nouns (words representing people, places, things, or ideas) have a singular form and a plural form.

For example, the singular form of "data" is "datum," and the plural form is "data" (yes, they share the same form!). Similarly, "user" stays the same in both singular and plural forms.

Mongoose's Default Pluralization Rule 💪

By default, Mongoose pluralizes your model names using a simple rule: it adds an "s" to the end of the model name. This rule works well for most English nouns, but as we've seen, there are exceptions like "data" and "user."

Overriding Mongoose's Pluralization Rule 🚀

Luckily, Mongoose provides an easy solution for handling irregular pluralization cases. You can explicitly set the collection name for your models using the collection option.

Let's modify your code examples to specify the desired collection names:

var Dataset = mongoose.model('data', dataSchema, 'data');
var User = mongoose.model('user', dataSchema, 'user');

With these changes, your collections will be named "data" and "user" respectively, without the extra "s" at the end.

Extra Tips and Tricks 🎁

• If you prefer singular collection names for all your models, you can set a global option by adding the following line of code before defining your models:

mongoose.pluralize(null);

• Remember to avoid naming conflicts when setting explicit collection names. Ensure that the collection name you specify doesn't clash with any existing collections in your MongoDB database.
