Is it possible to store a JavaScript object (including methods) within MongoDB?

I am looking for a solution to store objects containing text formatting methods and CSS styles in a MongoDB collection using Mongoose. The structure of the objects I have is more complex than this example:

const myStyle = {
    book: {
        templates: ["/authors/. ", "/title/. ", "/date/. "],
        authors: {
            format: formatAuthors
        },
        title: {
            format: formatTitle,
            style: {fontStyle: "italic"}
        }
    }
}

Does anyone have suggestions on how to send and save such objects in a MongoDB collection? It seems that Object cannot be used as a schemaType according to the Mongoose documentation, making it challenging to save them directly as JavaScript objects.

Answer №1

To create custom methods in Mongoose, you can use the Schema.methods field.

SchemaName.methods.methodName = function(){...}

For a practical example of how to use mongoose, check out this link.

Answer №2

Object is not an acceptable type for a mongoose schema, but you can use Mixed instead.

As a SchemaType that allows for anything, using Mixed provides flexibility but may be challenging to maintain. Mixed can be accessed through Schema.Types.Mixed or by passing an empty object literal.

More detailed information on this topic can be found at the link provided above.

If the data you wish to store is a valid JavaScript object, you should have no trouble inserting it.

It is important to recognize that as a schema-less type, Mixed has certain performance limitations. Additionally, make sure to call .markModified(path) when making changes, as outlined in the documentation.

Answer №3

Sorry, but it is not possible to store methods in mongodb.
