How to use Enum with Default Values In Mongoose
We can specify a default value for a field with enum and ensuring that it always has a valid initial value.
const userSchema = new mongoose.Schema({
role: {
type: String,
enum: ['user', 'admin', 'moderator'],
default: 'user' // Default value for the 'role' field if not specified during document creation
}
});
Explanation: This Mongoose schema defines a role field with a type of String and an enum specifying that the field can only have the values ‘user’, ‘admin’, or ‘moderator’. Additionally it sets a default value of ‘user’ for the role field if no value is provided during document creatio
