Parsing Array in NodeJS

Our Goals –
• Parsing Array in NodeJS App

Assumption
We already have a NodeJs project “myschool” in our working directory. If you don’t have the project then please create it. We have discussed it on our previous tutorial.

To do so –
1. Open comand prompt at our working directory and install “body-parser” by typing “npm install body-parser –save”.
2. And the out put will be like –

3. The “package.json” file will looks like –

{
  "name": "myschool",
  "version": "1.0.0",
  "description": "My First Project in NodeJS",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "Tanmay Sarkar",
  "license": "ISC",
  "dependencies": {
    "body-parser": "^1.17.0",
    "express": "^4.15.0"
  }
}

4. Open “app.js” file and paste the following code.

5. Now run this app using “node app” command at command prompt.
6. Now at command promt the output will be –

7. Open your browser and type http://localhost:5000/ and it will show the result as –

8. And if you check the console, the log will displayed as –

9. To terminate the server press “Ctrl+c”

Source Code :

var express = require('express');
var parser = require('body-parser');
var app = express();
var person =[
	{
		fname : 'Tanmay',
		lname : 'Sarkar'
	},
	{
		fname : 'Harold',
		lname : 'Finch'
	},
	{
		fname : 'John',
		lname : 'Reese'
	}
]
app.get('/',function(req,res){
	res.json(person);
	console.log('user accessing array parsing page');
});
app.listen(5000,function(){
	console.log('server running on port 5000');
})

Thank you.
