Express restful api expecting json array - node.js

Question

I'm trying to integrate an Excel spreadsheet with my application using an node.js Express Restful Api. My API already accepts simple json like:
{
"num": "1",
"name": "Adams"
}
But now i need to send array of objects like:
[
{
"num": 1,
"name": "Adams"
},
{
"num": 2,
"name": "Phillips"
}
]
I'm using mongoose to connect to a mongoDB server and already the following function connected to a route in my api to accept single objects:
create_a_budget: function (req, res) {
var budget = new budgetModel({
user_id : req.body.user_id,
seq_budget : req.body.seq_budget,
date_done : req.body.date_done,
num_budget : req.body.num_budget,
medium : req.body.medium,
client_name : req.body.client_name,
email : req.body.email
});
budget.save(function (err, budget) {
if (err) {
return res.status(500).json({
message: 'Error when creating budget',
error: err
});
}
return res.status(201).json(budget);
});
}
But i don't have a clue about how to treat the array

Answer 1

You can simply pass an array of documents received from mongodb in res.json. res.json() will handle array properly. You dont have to do anything else. Example of the same:-
db.budget.find(query, (err, budgets) {
if(err) {
// handle error
}
return res.status(200).json(budgets);
});
