I want to get record based on title so I have passed parameter as /blog/:title' but it is populating whole json file ?

I have posts.json file. after hitting http://localhost:3000/blog/santosh it is returning whole array of Object and not only single record app.get('/blog/:title',function(req,res){ res.send(posts); });

Hi Margee,

In the example video Huston does a couple of things to return a specific part of the posts JSON file. I've commented his code below to explain it but can help out further if you post the full version of your code :)

var posts = require('./mock/posts.json');

app.get('/blog/:title?', function(req, res){ 
    /*this title variable is equal to the url te user inputs*/
    var title = req.params.title;

    /*if the url doesn't match any blog title, return 503*/
    if (title === undefined) {
        res.status(503);
        res.send("This page is under construction!");
    } else {
        /*otherwise, if there is a match
          pass the title string (received in url - in your case "santosh") to the posts json object*/
        var post = posts[title];
        res.send(post);
    }
});

```Sebastian : Thanks for quick reply My Posts.json file look like this. posts.json [{ "id": 1, "title":"santosh", "body":"<h1> Hello</h1>" }, { "id":2, "title":"ganesh", "body":"<h1> Konichiwa </h1>" }, { "id": 3, "title":"kiran", "body":"<h1> Hallo </h1>"

}]

app.js

'use strict';

var express= require('express'); var posts=require('C:/Users/santosh/Desktop/Node.js/express/express-basics/mock/posts.json'); var app= express(); app.set('view engine','jade'); app.set('views',__dirname +'/templates'); app.get('/',function (req,res) { //res.send('<h1> I Love Express</h1>'); res.render('index'); }); app.get('/blog',function(req,res) { res.send(posts); }); app.get('/blog/:title',function(req,res){ debugger; var title=req.params.title; if(title===undefined) { res.status(503); res.send("This page is under construction!"); } else{ var post=posts[title]; res.send(posts); }

}); app.listen(3000,function(){ console.log('The frontend server is running on 3000 port'); });
