I can't seem to figure out what's going wrong with my code. I've checked the documentation and it all appears to be correct. I've also gone through several posts and attempted various solutions.
Code:
router.get('/rank/:rank', async (req, res) => {
const users = await loadUserCollection()
const query = users.find({rank: req.params.rank}, {projection: {email: 0, password: 0}})
res.json(query)
})
async function loadUserCollection() {
const client = await mongodb.MongoClient.connect(mongoUri, {useNewUrlParser: true})
return client.db('myFirstDatabase').collection('users')
}
