mongojs驱动程序未连接到mongodb

Question

i have been trying to connect to my local mongodb using mongojs package but its not connecting at all. i have my mongo service running on http://127.0.0.1:27017/ and below is my code :

    var express = require('express');
var app  = express();
var bodyParser = require('body-parser');
var mongo= require('mongojs');
var db=mongo('catalog',['products']);

app.use(bodyParser.json);
//adding our first route  name 
db.on('connect', function () {
    console.log('database connected')
})
app.get('/',function(req,res){
    res.send('It Worked');
});
app.get('/products',(req,res)=>{
    db.products.find(function (err,docs) {
        if (err) {
            res.json(err)
        }else{
            res.json(docs)
        }
    })
});

i have set event on connect to log if the connection is established but nothing is showing up.do you i could use mongoose or some other packages if it doesnt work at all?

Answer 1

mongojs doesn't fire the connect function until you make the first request to a collection. Make a request to your collection and the on('connect') function will fire.

Or in your case go to /products in your browser and you can see the database connected log in your terminal.

If you want to request records from your collection without going to /products in your browser then just write your query outside of your app.get('/products') .

Make sure you add

app.listen(3000, function() { 
  console.log('server is running');
});

at the the end and go to localhost:3000/products in your browser.
