How can we rewrite this?

Currently I’m using a timer with node-schedule to check for changes in the database, making queries every 1 minute and then comparing with the information already registered to see if there were changes since the last check.

With what I want to do I want to decrease the amount of unnecessary queries and be able to bring the data in real time, and this is interesting because I am using this timer to provide statistics on the amount of users, categories and articles.

I am using Knex as query-builder in my db.

This is my file with the timer (I am using MongoDB to store this information):

const schedule = require('node-schedule')

module.exports = app => {
    schedule.scheduleJob('*/1 * * * *', async function () {
        const usersCount = await app.db('users').count('id').first()
        const categoriesCount = await app.db('categories').count('id').first()
        const articlesCount = await app.db('articles').count('id').first()

        const { Stat } = app.api.stat

        const lastStat = await Stat.findOne({}, {},
            { sort: { 'createdAt': -1 } })
        
        const stat = new Stat({
            users: usersCount.count,
            categories: categoriesCount.count,
            articles: articlesCount.count,
            createdAt: new Date()
        })

        const hasChanged = !lastStat
            || stat.users !== lastStat.users
            || stat.categories !== lastStat.categories
            || stat.articles !== lastStat.articles;
        
        if (hasChanged) {
            stat.save().then(() => console.log('[STATS] Estatísticas atualizadas!'))
        }
    })
}
