// This is the simplest setup.
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))
// parse application/json
app.use(bodyParser.json())
app.use(function (req, res) {
res.setHeader('Content-Type', 'text/plain')
res.write('you posted:\n')
res.end(JSON.stringify(req.body, null, 2))})
Example 4: urlencoded json express
var express = require('express')
var app = express()
app.use(express.json()) // for parsing application/json
app.use(express.urlencoded({ extended: true })) // for parsing application/x-www-form-urlencoded
app.post('/profile', function (req, res, next) {
console.log(req.body)
res.json(req.body)
})
Example 5: bodyparser purpose
//body-parser helps parse json files
//you can use body-parser anytime you need to use a form to post
//data to a request
var bodyParser = require("body-parser");
app.use(bodyParser.urlencoded({extended: true}));
