How to Create and Use Enum in Mongoose

849    Asked by AmitSinha in Spark , Asked on May 12, 2021

I am trying to create and use an enum type in Mongoose. I checked it out, but I'm not getting the proper result. I'm using enum in my mongoose schema as follows:

var RequirementSchema = new mongoose.Schema({ 
status: { 
type: String, 
enum : ['NEW', 'STATUS'], 
default: 'NEW' 
}, 
})

But I am a little bit confused here, how can I put the value of an enum like in Java NEW("new"). How can I save an enum into the database according to its enumerable values? I am using it in express node.js.

To Create and Use mongoose enum, mongoose has various inbuilt validators. Strings have enum as one of the validators. So enum creates a validator and checks if the value is given in an array.

var userSchema = new mongooseSchema({ 
userType: {
type: String,
enum : ['user','admin'],
default: 'user'
},
})
