Nodejs Rest API with mongoose and mongoDB - node.js

Question

I have this rest API on nodejs as follows
router.route('/api/Customers')
.post(function(req, res) {
var Customer = new Customer();
Customer.name = req.body.name;
Customer.save(function(err) {
if (err)
res.send(err);
res.json({ message: 'Customer created!' });
});
})
.get(function(req, res) {
Customer.find(function(err, Customers) {
if (err)
res.send(err);
res.json(Customers);
});
});
router.route('/api/Customers/:Customer_id')
.get(function(req, res) {
Customer.findById(req.params.Customer_id, function(err, Customer) {
if (err)
res.send(err);
res.json(Customer);
});
})
.put(function(req, res) {
Customer.findById(req.params.Customer_id, function(err, Customer) {
if (err)
res.send(err);
Customer.name = req.body.name;
Customer.save(function(err) {
if (err)
res.send(err);
res.json({ message: 'Customer updated!' });
});
});
})
.delete(function(req, res) {
Customer.remove({
_id: req.params.Customer_id
}, function(err, Customer) {
if (err)
res.send(err);
res.json({ message: 'Successfully deleted' });
});
});
How can I create endpoints for specific fields ? For example if I want to GET results for CustomerName, CustomerZip, etc .. Do I have to create separate end points for each field?

Answer 1

Are you using express.js as framework? In this case you can put optional params in your route, for example:
router.route('/api/Customers/:Customer_id?')
.post(function(req, res) {
...
})
.get(function(req, res) {
...
});
});
in this way :Customer_id will be optional and you can manage logic inside your route.
This is a working example:
app.route('/test/:param1?/:param2?')
.get( function(req, res, next) {
res.json({
'param1' : req.params.param1,
'param2' : req.params.param2
});
});
app.listen(8080);
this route supports:
/test
/test/1
/test/1/2
inside response you can see value of this params, I don't know how pass only param2 without param1.
