Question

describing a schema for a mongoose model in a TypeScript environment

I am currently working on a function named createFactory, which requires two parameters - a model and a data object. The purpose of this function is to generate a document based on the provided data.

const createFactory = (Model, obj: object) => {
    Model.create(obj)
}

However, TypeScript is issuing a warning because the type of Model is not specified. As a result, when I attempt to access properties or methods of Model in VScode by typing "Model." and pressing ctrl+space, code completions are not displayed.

What is the correct way to address this issue in my code?

typescript mongoose

If you want to streamline your code when working with mongoose, you can utilize specific definitions from the package and apply them to your functions. Even though it may seem daunting at first.

import {Model, Document, CreateQuery} from "mongoose";

const createNewDocument = <T extends Document>(model: Model<T>, data: CreateQuery<T>) => {
    return model.create(data);
}

To ensure that your Model is a valid mongoose model, we import the Model interface. This interface is customizable based on the document type T, which should be an extension of the base Document interface. Only certain types of objects are suitable as arguments for the create method, so we specify this using Mongoose's CreateQuery<T> type definition.
