As explained here in the mongoose documents https://mongoosejs.com/docs/validation.html , you can use doc.validate(callback) or doc.validateSync() to check for validation.

The difference is that you do not have to use await for validateSync() as its name suggests. it returns an error if validation fails, otherwise, it returns undefined. for example:

const model = new Model({somedata:somedata})

const validatedModel = model.validateSync()
if(!!validatedModel) throw validatedModel
