mongoose-expiring-schema

Build Status Dependency Status

A schema plugin that allows documents to have expiration dates, and defaults queries to respect these.

This plugin is meant to be used on a class of documents that is only valid for a certain period of time. That mainly means that the document might have a validFrom date (which means it is only valid AFTER the specific time) and an validUntil date (which means it is only valid until that date). Either of these values can be null, which means the document is valid indefinitely on that end.

When querying for documents that have this plugin, by default, documents will only be returned if they are currently valid.

Getting Started

const ExpiringSchemaPlugin = require('mongoose-expiring-schema');
const ticketSchema = new mongoose.Schema({ concertId: String });
 
ticketSchema.plugin(ExpiringSchemaPlugin);
const TicketModel = mongoose.model('ticket', ticketSchema);
 
// Results will only contain tickets that are currently valid
const results = await Model.find().exec();
 
// Results will only contain tickets that were valid on `someDate`
const results = await Model.find({ validAsOf: someDate }).exec();
  • Note that you can use null for validFrom or validUntil to represent that there is no bound on when it starts being valid or when it stops being valid, respectively.

Configuration

defaultValidFilter: You can specify a function that provides a different default query to determine if documents are valid or not. By default, all currently valid documents come back. The function takes a parameter that is a Date() representing when "now" is for the query.

ExpiringSchemaPlugin contains a constant that has two options in it:

  • VALID_FILTERS.CURRENT (default): Queries for docs current valid.
  • VALID_FILTERS.CURRENT_AND_FUTURE (default): Queries for docs current or future valid.

Access these via require('mongoose-expiring-schema').VALID_FILTERS.
