Example

`typescript
// On your application startup
import mongoose from 'mongoose'
import cache from 'ts-cache-mongoose'

// In-memory example
const instance = cache.init(mongoose, {
defaultTTL: '60 seconds',
engine: 'memory',
debug: true, // Debug mode enables hit/miss logs in console, not for production use
})

// OR

// Redis example
const instance = cache.init(mongoose, {
defaultTTL: '60 seconds',
engine: 'redis',
engineOptions: {
host: 'localhost',
port: 6379,
},
debug: true, // Debug mode enables hit/miss logs in console, not for production use
})

// Connect to your database
mongoose.connect('mongodb://localhost:27017/my-database')

// Somewhere in your code
const users = await User.find({ role: 'user' }).cache('10 seconds').exec()
// Cache hit
const users = await User.find({ role: 'user' }).cache('10 seconds').exec()

const book = await Book.findById(id).cache('1 hour').exec()
const bookCount = await Book.countDocuments().cache('1 minute').exec()
const authors = await Book.distinct('author').cache('30 seconds').exec()

const books = await Book.aggregate([
{
$match: {
genre: 'fantasy',
},
},
{
$group: {
_id: '$author',
count: { $sum: 1 },
},
},
{
$project: {
_id: 0,
author: '$_id',
count: 1,
},
}
]).cache('1 minute').exec()

// Cache invalidation

// To clear all cache, don't use in production unless you know what you are doing
await instance.clear()

// Instead use custom cache key
const user = await User.findById('61bb4d6a1786e5123d7f4cf1').cache('1 minute', 'some-custom-key').exec()
await instance.clear('some-custom-key')
