Express App: What's In Query

Oftentimes, we need to process the data from the URL query string (urlencoded).

Write a route that extracts data from the query string in the GET /search URL route, e.g. ?results=recent&include_tabs=true and then outputs it back to the user in JSON format.

Use app.get('/search', function(){...}) for the route.

In Express.js, to extract query string parameters, we can use (inside the request handler):

req.query.NAME

HINTS

No need to install query middleware. It's part of the Express.js framework.

To output JSON we can use:

res.send(object)

My Solution

var express = require('express');
var app = express();
var url = require('url');

app.get('/search', function(req, res) {
  var parsedURL = url.parse(req.url, true);
  res.send(JSON.stringify(parsedURL.query));
});

app.listen(process.argv[2]);

Official Solution:

var express = require('express')
var app = express()

app.get('/search', function(req, res) {
  var query = req.query
  res.send(query)
})

app.listen(process.argv[2])
