From your last code snippet, seems like you using Express or similar framework. You can use express-mongo-db to get connection inside req object. This middleware will cache connection for you and share it with other incoming requests:

app.use(require('express-mongo-db')(require('mongodb'), { db: 'test' }))
app.post('/employee', function(req, res){
    // req.db.collection('names'),insert(req.name)
    // Put req.name in database
});


app.post('/car', function(req, res){
    // req.db.collection('names').insert(req.name)
    // Put req.car in database
});
