Setting expiry time for a collection in mongodb using mongoose

Solution 1:

In Mongoose, you create a TTL index on a Date field via the expires property in the schema definition of that field:

// expire docs 3600 seconds after createdAt
new Schema({ createdAt: { type: Date, expires: 3600 }});

Note that:

• MongoDB's data expiration task runs once a minute, so an expired doc might persist up to a minute past its expiration.
• This feature requires MongoDB 2.2 or later.
• It's up to you to set createdAt to the current time when creating docs, or add a default to do it for you as suggested here.
  • { createdAt: { type: Date, expires: 3600, default: Date.now }}

Solution 2:

this code is working for me.

may it help

let currentSchema = mongoose.Schema({
    id: String,
    name: String,
    packageId: Number,
    age: Number
}, {timestamps: true});

currentSchema.index({createdAt: 1},{expireAfterSeconds: 3600});
