Unable to send numbers using res.send() using express with node

I am trying to get the \"imdb rating\" using express in node and I am struggling.

movies.json

[{
\"id\": \"3962210\",
\"order\": [4.         


        

Answer 1

this works, you have to convert it to a string: threeFunction().toString() or x1.toString()

Answer 2

Integer is not valid for res.send() so convert it to string.

res.send(value.toString())

Answer 3

According to Express res.send([body]) docs:

The body parameter can be a Buffer object, a String, an object, or an Array

You can't send a number by itself.

Try either converting the number to a string

res.send(''+result.rows[0].doc.imdb.rating);

or send it as an object value

res.send({ result: result.rows[0].doc.imdb.rating});
