Always populate() certain fields in your mongoose schemas
npm install mongoose-autopopulateAlways populate() certain fields in your mongoose schemas


Note: population is a powerful feature, but it has limitations and
helps you get away with poor schema design. In particular, it is usually
bad MongoDB schema design to include arrays that grow without bound in
your documents. Do not include a constantly-growing array of ObjectIds
in your schema - your data will become unwieldy as the array grows and
you will eventually hit the 16 MB document size limit.
In general, think carefully when designing your schemas.
The mongoose-autopopulate module exposes a single function that you can
pass to Mongoose schema's plugin() function.
``javascriptpopulate()
const schema = new mongoose.Schema({
populatedField: {
type: mongoose.Schema.Types.ObjectId,
ref: 'ForeignModel',
// The below option tells this plugin to always call onpopulatedField
// `
autopopulate: true
}
});
schema.plugin(require('mongoose-autopopulate'));
Only apply this plugin to top-level schemas. Don't apply this plugin to child schemas.
`javascriptnestedSchema.plugin(require('mongoose-autopopulate'))
// Don't do .``
// You only need to add mongoose-autopopulate to top-level schemas.
const nestedSchema = mongoose.Schema({
child: { type: Number, ref: 'Child', autopopulate: true }
});
const topSchema = mongoose.Schema({ nested: nestedSchema });
topSchema.plugin(require('mongoose-autopopulate'));
