Typescript + mongodb : create index - mongodb

Question

Hello I'm having trouble creating an index to delete automatically expired rows something like:
db.eventlog.createIndex( { created_at: 1 }, { expireAfterSeconds:
3600, partialFilterExpression: { state: 'TMP' } } );
my code:
export type PasswordRecoveryAttributes = {
employee_id: string;
email: string;
token: string;
used: boolean;
expiration: Date;
latitude: string;
longitude: string;
};
const PasswordRecoverySchema = new Schema(
{
employee_id: {
type: String,
trim: true,
required: true,
},
email: {
type: String,
lowercase: true,
trim: true,
required: true,
},
token: {
type: String,
trim: true,
required: true,
},
used: {
type: Boolean,
trim: true,
default: false,
required: true,
},
expiration: {
type: Date,
},
ip: {
type: String,
trim: true,
required: true,
},
latitude: {
type: String,
trim: true,
required: false,
},
longitude: {
type: String,
trim: true,
required: false,
},
},
{
timestamps: true,
},
);
type PasswordRecoveryDoc = Document & PasswordRecoveryAttributes;
export interface PasswordRecoveryDocument extends PasswordRecoveryDoc {}
// For model
export interface PasswordRecoveryModel extends Model<PasswordRecoveryDocument> {}
export default mongoose.model<PasswordRecoveryDocument>(
'PasswordRecovery',
PasswordRecoverySchema,
);
connection:
(async () => {
const mongoUserPass = mongoConfig.username
? `${mongoConfig.username}:${mongoConfig.password}#`
: '';
const connection = await mongoose.connect(
`mongodb://${mongoUserPass}${mongoConfig.host}:${mongoConfig.port}/${mongoConfig.database}`,
{
useNewUrlParser: true,
useUnifiedTopology: true,
useCreateIndex: true,
useFindAndModify: false,
},
);
})()
But I’m not able to imagine how to do this in typescript and
Mongo

Suggestions: It would help your work if your can think in terms of
Mongoose, which was meant for this, it helps you in this task to model your objects for MongoDb
To answer your question:
class EmployeePassword {
...
#index(1, { unique: true, sparse: true, name: 'email_unique_index' }) email: string;
#index() someId: number;
}
Now with Mongoose a good example:
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const EmployeePassword = new Schema({
employee_id: string;
email: string;
token: string;
used: boolean;
expiration: Date;
latitude: string;
longitude: string;
});
