How can I make a mongoDB schema delete in 5 min-CodePudding

So im making a verification code sorta thing, they get the code then they can verify. But, I want to make it so it expires in 5 min (so the db isnt filled with random stuff) after creation how would I go about doing that.

CodePudding user response：

You can add expireAt as time-to-live parameter with createIndex.

To create a TTL index, use the createIndex() method on a field whose value is either a date or an array that contains date values, and specify the expireAfterSeconds option with the desired TTL value in seconds.

db.eventlog.createIndex( { "lastModifiedDate": 1 }, { expireAfterSeconds: 3600 } )

Document will expire in 1 hour and will be deleted automatically by mongodb.

Check this documentation | TTL indexes

Update:

In mongoose you can this parameter directly in Schema constructor

const schema = Schema({ name: String, timestamp: Date, metadata: Object }, {
  expireAfterSeconds: 86400
});
