Error Code 

You will face this error if you are using app.configure in an express js application.

var express = require('express'),

    app     = express(),

    port    = parseInt(process.env.PORT, 10) || 8080;

app.configure(function(){

  app.use(express.bodyParser());

  app.use(app.router);

});

app.listen(port);

app.post("/myRoute", function(req, res) {

  console.log(req.body);

  res.send({ status: 'SUCCESS' });

});

Solution

app.configure is removed in Express 4 and above .

Code Changes 

add the following import in your component.ts file .

  

        

var express = require('express');

var bodyParser = require('body-parser');

var app = express();

app.use(bodyParser.urlencoded({ extended: true }));

app.use(bodyParser.json());

app.post('/api/users', function(req, res) {

   console.log(req.body);

  res.send('success');

});

app.listen(8082);

         

OUTPUT

works
