Get row count before LIMIT but on it's own row - json

Question

I'm trying to get the full row count before i limit the return in postgres, which I have using:
count(*) OVER() AS full_count
However as I put it in the select it outputs it with every row which is less then ideal. I'm outputting it in NodeJS as JSON and noticed that the output contains it's own tow with rowCount, but this is after the limit, is there a way to replace the rowCount in the JSON with full_count, or a better way of trying to do what I'm doing? This is my query thus far:
SELECT name, id, count(*) OVER() AS full_count FROM table ORDER BY id ASC LIMIT ($1) OFFSET ($2)
Update
Expected output:
{
total : 170000
rows : [
{
name : Karl,
age : 31,
},
name : Helen,
age : 36
}
]
}

NodeJS
Route
router.get('/api/v1/person/:limit?/:offset?', (req, res, next) => {
person.get(req, res);
});
Model
this.get = function(req, res) {
var limit = req.params.person_limit || 10;
var offset = req.params.person_offset || 0;
if (limit > 100) {
limit = 100;
}
pool.connect(function(err, client, done) {
if(err) {
done();
console.log(err);
return res.status(500).json({success: false, data: err});
}
client.query('SELECT name, id FROM person ORDER BY id ASC LIMIT ($1) OFFSET ($2)',[limit, offset], function(err, result) {
done();
if(err) {
return console.error('error running query', err);
}
res.send(result);
});
});
};
